Touch screen faulty; can only use voice control and physical buttons - Galaxy Tab 3 Q&A, Help & Troubleshooting

~~

Braxton343 said:
I'm working on a Sprint T217S Galaxy Tab 3 that I gifted to my grandmother a few years back. I had completely reset it beforehand, so developer options are disabled as far as I know. It has had battery issues lately, so I ordered a battery. It arrived today, and my grandma happened to stop by. She told me that she can't use the touch screen anymore, and after further inspection, the digitizer seems to be completely unresponsive.
Here's my dilemma: The entire digitizer is faulty (no menu/back button or touch input), and OTG support seems to not be working. I can connect via USB to the computer, and I believe it takes charge. I cannot however plug in a mouse/keyboard via OTG to navigate the tablet. My only option seems to be using voice input, but all it can do is open settings/handle very basic tasks.
Is there anything I can do? I've considered side-loading apps, but I can't tap anything to establish a connection via apps or settings in the slide down menu to enable bluetooth, etc. I'm at a loss, because I told her I could figure it out soon. I didn't realize how long this would take since I might be looking at a digitizer replacement, and shipping would take a while (weekend). Really appreciate any help, thank you!

If your voice controls can get you in there, set up a Bluetooth mouse.

[Q] Touch Screen Problem

Recently I began to notice a problem with my phone. Whenever I have the keyboard slid out the touch screen is almost non-responsive. So over the past few days I've tried observing what the exact problem is and I think it could be the cable/ribbon that connects the touch screen to the keyboard. I'll have to tilt the screen back and forth before it will actually recognize me touching it. And I've noticed when I rub that ribbon it seems to work. There's also a crease in the ribbon where it folds on it when you close it. I believe this is the problem but I'm not sure and I want any advice/tips I can get. If it is the cable can you order a new one and replace it yourself?
Thanks in advance
Any ideas anyone? I cant get it to half work so I can text and stuff but I have to press it hard and it still wont work at times so something somewhere or another is wrong.

Flash the stock ROM and SPL, and do a warranty exchange. This isn't a device you want to open up unless you really know what you're doing and are certain of the issue. If you really want to give it a go, then just buy a non-functioning unit from eBay to use for parts. They can normally be had for less than $40.
Wow, I cant believe that I finally found someone with the same problem as I have.
At first I thought that it was a software issue and I reloaded the software on my device.
The screen responds to presses with the keyboard in, but extended it doesnt respond and only the external keyboard works.
So to type a nice long sms I would have to start it on my display, flick out the keyboard to carry on and then flick it back in before I could press send or anything.
How frustrating.
But I did a test now and flicking the keyboard out and then slowly slowly pushing it back in I can get to a stage where both the external keyboard and screen responds at the same time again.
Definitely a ribbon problem or something.
Only had this phone for a few months now and if it already doing this then I am not feeling too obtimistic about its future.
Well, time to take it in for a warranty repair. I wonder how much greaf I am in for now.
Time to pull out my awesome trusty Artemis out the cuboard.

I had a friend that had this problem with his TP2 which I've successfully repaired. First thing if you want to do it yourself, go to youtube and look for the Rhodium disassembly video (this will help you a lot). It is not difficult to change any parts in the phone provided that you proceed with caution and take the necessary precautions.
If you are afraid or have never opened up a phone to fix parts, then I would suggest to send it to HTC - this would be devastating if you managed to break up the motherboard by mistake or any other parts in the process of fixing the flex cable.
Tripp --
Did you ever find resolution to your problem? Recently my phone started having the same problem, which I originally thought was related to messing up the calibration file when I put loaded xdandroid GBX0A.
However, it sounds like my problem is pretty similar to yours -- touchscreen works fine when the keyboard is closed, but when it is open it only registers on the bottom of the screen -- which is actually useful in some sense because I can still hit the soft keys in the messaging app and such, but not so useful if you want to scroll using the touch screen. If I play around with the z-hinge a bit, sometimes it starts working -- which sounds like the same thing that you described.
Sorry, I just seen your post but I never fixed mine as I went ahead and bought another phone (Evo) but I did research the problem quite extensively and the problem I believe lies in the ribbon that connects the two halves of the phone. If I remember correctly the motherboard is in the side with the keyboard and that's why when it's slide out, the touch screen won't respond correctly. You can find the part online and replace it yourself. I've taken mine apart and it's not that hard but as said, you need the right tools and to be very careful.
Hi guys
I have tried all the above
Last resort is i got sprite backyup to work
BUT HOW THE HELL DO YOU HIT "NEXT" OR "OK" FROM THE KEYBOARD AS SCREEN DOESNT WORK????

Microsoft Wedge Mouse

I have no problem connecting to my LG phone which is running Android 4.1.2 but for the life of me I cannot get my Note 10.1 2014 to connect or even see my wedge mouse. Any ideas?

I was able to get mine successfully paired and working. Just got my new Note 10.1 today.
In the bluetooth setting, making sure I check-marked "make device discoverable" I flipped my Wedge over, pressed the power button once until it lit steady blue, then held it down until it went into pairing mode, then I hit 'Scan' on the Note and in seconds it found the Wedge mouse.
Perfect!

I made the device discoverable. The problem I had was the 1-2 punch of (1) turning the mouse on & (2) then pressing and holding to get it into pairing mode. I guess I got lucky when I was messing with it on my phone and got it paired.

Ah, you are far better than I. Some products default to discoverable mode, others not. It took me several tries on some devices to realize I had to put it in discoverable mode myself - basically, not paying attention to the screen text - and I found most fam/friends did the same, so I assumed that was the issue. Nonetheless, the connection button actions ... it took me three attempts to figure that one out
But tell me, do you find the cursor movement erratic with the Wedge on the Note 10.1 (2014)? Mine seems to be jerky quite often, sluggish to perform a movement.

So far it is jerky. I'm not too sure how much I will use it since the sPen does mostly the same thing anyway. Overall I'm very happy with the tablet but maybe when/if we get all 8 cores up and going or once we get our tablets fine tuned just like we want them, things will settle into place.
For those of you that have it working, what does the right-click on your mouse do? I have a note 10 (2012 version) and will probably be upgrading to the 10 or 12. I have one major problem using my note as a work terminal connecting to a citrix session: The right mouse button acts as a 'back' command in anything, including within the citrix session. I have another, older samsung 10" tab and the right click is ignored at the OS level, but within Citrix it works as expected. I believe the OS is applying a default behavior of a 'back' function to any right click on the later device(s) and am wondering if anyone here has any input on it's behavior in the latest devices.
Thanks for any input

[Q] Screen wont turn on

I have the new Galaxy Note 2014 edition tablet, as does my son. My son came home today with his tablet and told me the screen no longer turns on. He said he was playing a game with a friend when the screen flickered and then went dark. Nothing seems to bring it back online.
Tried to press the power button and volume up button for a forced reboot. Most times does not but it did reboot once and stayed black.
Also tried pressing the power button down while pressing a finger on the screen, apparently a solution to sleep of death or something. I can't tell if that does anything - if anything it seems to turn it off or something because it has become unresponsive after doing that.
Any thoughts on what to do next?

I seem to be able to get it into two states right now, but neither is like it was - powered on and "working" but no screen. If I hold the power button for a while it seems ot go into a deep state of sleep or off, but I do not quite think it is off. If I hold it again for 30 seconds nothing happens at all. If I hold it again for 4 seconds, the back and menu soft keys will light up again. And then I can get them to light by hitting the home button or a quick touch of the power button.
Press and hold power in either state while holding volume up no longer seems to take me to a reboot - I no longer hear the power up music.
No idea what state it really is in or how to get it out of this.
ok - I think when it is able to light the buttons - it actually is still on. I just heard the vibration notification of an incoming alert (email, twitter or something).

Use the function to chat with the amazon support.
just google "Amazon Support". You will find the option on the right side on the amazon page
They will know what to do and from my experience amazon will offer you that you can send your tablet either to amazon or directly to samsung and they wil pay the shipping costs good luck !

Its a problem with your tablet. I know of a few other people in other threads who have also experienced this. My experience was different though because mine didn't turn on out of the box. I think there's a problem with Samsung's display connector. Your best bet is to just get it replaced at this point.

Yeah - it looks like that. I was hoping for a service option because my son has a lot of homework on it that would be nice to retrieve and of course he is bummed that he might lose all his game stats. I tried ot hook the device up to the pc to see if I could copy some files but although the device shows, its internal drives do not show up.
I really do not know what state the device is in right now. The soft buttons light up and if i pull the smart pen out it vibrates as it acknowledges it has been taken out, and I can hear the occasional vibration notification as an email, twitter update, or some other notification comes in. So - it "seems" like it is on. But I can not get it to do a forced boot and a few other things seem not quite right.
Anyway - Thanks for the help everyone!

That's strange that you can't see the drives when connected to the computer. If you look really closely though it could just be the backlight not turning on when the actual lcd is turning on. If you really need to see whats on the screen and try to find a way to send the files to yourself or upload them somewhere you can try taking a screenshot while the tablet is connected to the computer and check the screenshots folder to see what is on the screen at a certain time. I know it could take a while, but if what's on the tablet is really important it could work. Best of luck.

I tried to see if there was anything vaguely showing but the screen is totally black as far as I can see. I have a service ticket open with Samsung and will send it back for repairs. I would prefer repair over replacement as I would hate to lose all the stuff installed. I generally trust repairs as my philosophy is that they tend to pay better attention on the repair than the assembly line.
Thanks for all the help everyone!
You should definitely try getting it repaired or see if it's possible to copy the data to an external storage prior to getting a new one.
As a general rule I always have Google Drive take automatic backups and store what I can on my external SD to prevent any loss of important work.

Don't you have to unlock the device for the drives to show up on the PC? It's probably waiting for the lock screen to be cleared.

This is what I am thinking - that it is sitting at the lock screen. I tried to see if I could unlock it by touching the screen in the right places but I guess when the screen is dark its not just dark but not functional. I figured as much but thought I would try anyway.

Well - its going back this morning for either repair or replacement. I would prefer repair to save the apps and data and work. Nothing irreplaceable but its a royal pain to reset all this up and my son had significant game experience on the device that might be nice to save.
Either way - it will just be nice to get it working.
Just wanted to follow up with the results. Got notification from Samsung yesterday that they repaired my device and it is on its way back. They replaced the LCD screen and the battery. All free and in warranty and coming back 2 day air.
Not sure why they replaced the battery. I wonder if the battery takes a beating because of 1 game that we play - Bloons TD5. It tends to drain the battery from full to empty in about 30 - 45 minutes. Any other game or function we do the battery last many hours. I wonder if that damages the battery long term?

Carperformance.se Uconnect Android system help.

I am hoping I can find some help in here with a couple problems I am running into on this system that would make it so much better to me.
The system is basically an Android box utilizing the touch screen and monitor of my Uconnect 8.4 head unit. The naming in the settings is rk3188 and is running on KitKat 4.4.4, so it is some variant of the Android TV boxes. If there are other specs or info that are needed to help in possibly fixing my issues please let me know.
Issue 1: although not major, there is no option to have OK Google from any screen. Having this option for a car system is obviously something helpful. In the settings of the Google App trying to access the menu for OK Google detection doesn't work, so I can't even get to the screen where that option lives. I have the most up to date version of Google App and Google Play Services. I have Google searched on ways to fix this but nothing has brought that ability up. I know Android version 4.4.4 was capable of this. There was another app that utilized Googles voice engine and allowed this function but Google made him stop using their servers and killed that as an option.
Issue 2: this is the biggest bother to me and I could not find anything even related to what's happening in my searches. The system comes loaded with some apps and using Launcher3 for its front end, it has big buttons but offers almost no ability to customize it. The bottom row has apps that you cannot switch out to anything else, and 3 of them I will never be using. The system works but is not as nice as it could look or function. The obvious answer is to use a different launcher which is where the problem arises. I have tried to use Nova and Apex so far with the same very frustrating outcome. After the install everything is great, I can set the screen up to look amazing and add icons and functionality that really make it a great experience. So everything is working lovely then I shut my truck off and go do whatever. The next time I come back I start the truck up everything loads fine, the new launcher and everything I did to it is working just as expected until about 5 minutes in the screen goes black for a second and then the system goes through a factory reset. Really? Are you kidding me? The first couple times I thought maybe I hit something because I hadn't fully put my truck back together but after playing with it more and having the system factory reset 5 other times I have concluded it is related to changing the launcher. I tried Nova first, then I tried Apex with the same outcome and same sequence of events. Obviously it's annoying everytime testing this because updating and reentering my info everytime just to try the launcher again is time consuming. The last test the only thing I did was a different launcher so that has to be it, but why and how can I fix it?
If anyone has any clue how using a different launcher would cause a factory reset to happen please help me out. Or if there is anything I can do to this system to prevent that. My last resort thought would be to root it but I read someone else who has this system that rooting it caused screen layout issues and made things go 90 degrees off? The loaded apps in the system have touch screen calibration and screen resizing which might be necessary for this to function with the monitor.
Thanks for any help.
I spoke with someone else that has the system and they are not having any issues with running a different launcher so something happen to my particular device. I contacted the company and they will be getting me the firmware to refresh it and hopefully that fixes the resetting issue.
i am looking to get this also. I am very curious how you like the device - it looks great though a bit out of date. Waze & email should work well. How much storage does it have? Can you add a sd card or something?

I'm getting a new unit sent out, it seems there are 2 versions and for whatever reason mine wouldn't let me customize the launcher.
But even though it's outdated, every app I tried worked just fine, they still install the latest versions. The system has 8gb of on board storage and a microSD card slot that is mainly for loading maps for offline navigation. I think you can still access it for other uses, but they have a better option for that. There is a USB input for flash drives or external drives. I tried my 2TB external drive on it and it accessed my movies fine from it.
How did you get it installed? Who?
got any pics?
Actually I would be interested in this too, I have an Alfa Romeo and the Uconnect 6.5 (european version) which isn't that great, it would be nice to attach a sort of box with ARM hardware running on Android and using the display and touch of the existing Uconnect. The question is, how this can be done?

I would check out this thread. It has two videos that walk you through the entire process - great info!

glad to hear i'm not going crazy with the clock but there is an issue.
I just bought and installed a V4 a couple weeks back too.
i must have left a loose connection cause i keep having to recall the touchscreen for android. I half-arsed the install cause we were leaving for a 2k mile roadtrip the next day- need to take it apart and do it right. Luckily you can connect a usb mouse in to trigger the calibration app.
id also love root- at the moment im trying to figure out if the one usb port is safe to connect an A to A usb cable into to get ADB. apparently on some versions of nvida sheild, you can. If they provide a firmware update for the clock fix then maybe that gets us an image to futz with for root.
a keyboard also works in teh usb port and i've tried a handful of key combos during boot to get to recovery but haven't stumbled on it yet.
I'll post back if i find anything

Hi @michaelk
Good to hear that I am not alone here with this special system V4. Except for the issue with the system time and no root access, I am fully satisfied so far. I hope to fix it soon. If we had root access then we could solve this issue with the system time with some time apps ourselves.
Thank you for your experiences.

wiring harness investigation
so played around some today.
I've got an issue where I need to recalibrate the screen almost every time I boot. it seems the box (or card added to the radio?) forgets things and only works the bottom right corner and also seems to rotate 90 degrees at boot. The end result is unusable screen. I think carperformance is just a reseller because of their response. They're friendly and reply quickly but are really unable to help. The first answer was just randomly fiddle with screen and try to find calibrate setting and reboot- that proved impossible and on my own I discovered a 6 dollar USB mouse from the Walmart could be used to navigate to the calibrate app. When I inquired again when it got more frequent they basically said it's not normal and offered no help except to adjust a personalization setting to run calibrate on boot- that only works once that I can figure (might be related to weird time bug)- so I settled on having tasker run calibrate on each boot. I wonder if there is a battery in the box that needs changing but the warranty sticker keeps me out for not- might add an external battery to keep it alive for a longer time to minimize the rebooting
Anyway took everything apart today to double-check and can't find any connection issues. I traced the harness a bit to try and understand a little and basically, the skinny cables run the daughterboard to snag the screen output and the touchscreen input. But i wanted to figure out what is tapped from the radio harness to the large white plug on the box and see if anything going on their .
DISCLAIMER- I NEED TO CONFIRM (it was hot - laughing) but basically seems what is tapped in radio harness is:
1) power and ground also
2) L&R aux audio signal- interesting here is they tapped a single ground (physically next to the right signal) for common. Earlier i had the RAX hack and their harness used a ground for each L&R and their aux input worked all the time without the little plugin shunt thing to trick aux input. When i dug some more and found a pin diagram from mopar I found that the 'left' ground is actually labeled "aux audio device detect signal" I need to play some more to see what happens but my guess is if we put a switch on that to short it to ground then the aux would just work to avoid the hokey plug.
3) Here's the fun- holding the screen to flip inputs could be the daughterboard running things. BUT since it also reacts to the left steering wheel button pack and switches inputs itself when you need the reverse cam- i figured it reads the can bus. and sure enough, it looks like it taps CAN IHS (+) and CAN IHS (-). Very cool that it would get into the whole bus and read anything- BUT since there are other FCA vehicles that don't auto-switch inputs on revers and they have alternate connections it seems the real dev is not involved to update things to sniff for other reverse signals. Reading around here- seems that there is probably a custom serial port someplace in the box that reads this and there's probably no documentation for us to do anything ourselves. But one can hope...

I just bought and installed a V4 a couple weeks back too.
i must have left a loose connection cause i keep having to recall the touchscreen for android. I half-arsed the install cause we were leaving for a 2k mile roadtrip the next day- need to take it apart and do it right. Luckily you can connect a usb mouse in to trigger the calibration app.
id also love root- at the moment im trying to figure out if the one usb port is safe to connect an A to A usb cable into to get ADB. apparently on some versions of nvida sheild, you can. If they provide a firmware update for the clock fix then maybe that gets us an image to futz with for root.
a keyboard also works in teh usb port and i've tried a handful of key combos during boot to get to recovery but haven't stumbled on it yet.
I'll post back if i find anything

So the spec for the chipset for the V4 says it can handle an OTG port and a couple (maybe 3?) other USB ports. Obviously, the box only has the one USB A port visible on the pigtail. I wish we could get in the box and look for a header for the OTG port to help rooting but.... the darn warranty sticker.
on the FCA/Dodge side of things- I have a Durango with a USB port and SD card reader in the dash (USB Media "Hub" Apparently, FCA uses USB Mini B connectors to interconnect all the ports and the radio. They use latching connectors that are keyed but if you undo them there's a standard USB mini B in there. They do some odd male/female things so you have to pay attention to where you undo cables, but bottom line you can undo the connector on the back of the dash's USB port and stuff a USB mini B female on it and connect it to whatever host device you want.
I first tried an old laptop in case there's anything weird going on. My Dash "Hub" actually has 2 mini-B connectors and a multipin auto harness. Without the harness when you connect it to windows it sees a USB Hub, but the USB port was still dead. So I assumed it needs power from the harness on the back of the dash hub and connected that. UP popped up a USB mass storage device which I believe is the SD card reader- didn't get around to confirming and then the USB port also comes to life. Knowing that it was safe at that point I connected it to the USB A Host port on the box and presto chango now I have the in-dash port connected to the android tv box without any exposed wiring.
Connected the "android auto dongle" through the cars USB port and that works perfectly. I ordered a used 2 USB dash hub from eBay (later model years have 2 and will see what that does. The pictures of that also show the 2 mini B ports- I'll play some more when I get that. I'm not sure what is in those dongles but from the other folks hacking android auto into older models (by using newer radios) apparently, one port works for android auto and the other doesn't. The scuttle is its a body module programming thing but I wonder if maybe there's something physical in there and so the dongle won't be necessary any longer with the new hub? My other thought is if the two USB min B jacks allow you to connect to 2 different hosts- I would try one on the original Uconnect (in case I ever need to update the software) and the other for the android TV box.
So apparently the android tv box handles hubs just fine. As I mentioned earlier it handles a mouse or USB keyboard fine. Also, I played around and connected my hotspot by USB instead of wifi so the device sees it as a modem and that works just fine- so I assume a USB modem works out of the box too. (again odd if that works that carperformance sells a hotspot and not USB modem- like they don't know what the box can do)
I disassembled my display 2 times until it worked. After the first start, I had a black screen. I thought that was it... After 3 times it finally worked. I also had a cable on the plug which has easily resolved. I think you will also have a loose contact somewhere. One time I also had the display calibration gone. Then I connected my old usb keyboard and could then start the display calibration. I reset the system before. So far, the system works without problems. I also have a passive 4-way usb hub to connect.
I have already connected cables for the frontcam but have not yet moved into the engine compartment.
In the video tutorial of Carperformance, you can see when you switch to drive, the display then changes to the frontcam or signal from the cam, but the display does not change to the Frontcam signal with me.
Do you have with you the signal on the display of the camera when switching to drive?
Adw2 = bad mix
Went back and forth many times in email and turns out my calibration issue was probably all ADW2 launcher, guess it conflicts with whatever app they use to communicate with the display.
in the process of troubleshooting I got the update zip for the current version but I don't think those have recovery partition in there and so can't help root? I need to read some more.
I've ripped everything apart like 12 times with the screen, so that my front cam is not connected right now. For the brief time I had it, it was connected to one of the smaller video in pin connectors and don't think it worked in drive by itself, but can't really say for certain. I think certain models can't get the canbus command to see reverse and if I understand they connect in to the video in on the main connector and then use a point on the car that is energized to trigger the switch on that connection. If your adventurous they seem to have to flip a dip also. I think it's the Cherokees or maybe grand Cherokee so maybe Google their thread's? This site gives connector pin outs
http://connectors.dcctools.com/home.htm
There might be a lead for the drive on your shifter if lucky. I think I read the reverse shoulder comes from a body control box in the passenger wheel well?
Also they're super friendly and never wrong when you email but they can be brief. So you could ask if there's a dipswitch to flip to enable auto switching one of the inputs. Hec maybe we should just ask for a table of where the dips do...
(Sorry for any typos... Will try to edit later)
Supposedly it is enough to connect the extra input cable for DVD or CMMB. That answered me Carperformance. Before, I had no external input cable connected. That's why no signal came. The OEM rearcam works flawlessly.
Also, I forgot, they have a workaround for the clock bug
For the clock there is a fix

It's a cheaper fix but so no solution. Carperformance should offer a software update with root access. Then we would be satisfied. We should expect it for the money.
My frontcam is working now good.
You already tried Android auto? Which USB dongle do you use? Do you need a special app for this?
My China usb dongle does not want to connect properly with my oneplus 6T.
Edit:
Android auto is working with Pumpkin USB dongle and autoplaybox app. The noname China scrap goes back to shop.
The time fix is working until now also. Thanks for this info. The carperformance, they wrote or informed the affected people who ordered it. I did not get any info.

besides powering your camera and connecting the yellow RCA video signal did you have to do anything else?
something with the red signal wire maybe?
I cant consistently get a signal on my front cam and not sure if the camera is bad or my setup

few other notes for others-
FCA "aux audio device detect signal" harness line is actually normally closed (I think shorted to ground)- if you break the connection the oew radio flips right to aux in. make the connection again and it flips back to previous input.
the in dash usb port is infact a powered hub. I originally had a usb + SD card combo and replaced it with 2 usb port and works fine. FCA uses mini b connections to it- just use a usb a to mini b cable to connect it to the android auto box and your indash usb port(s) will work on android auto (And provide more watts to charge your stuff). oddly either dahs hub has a second usb mini b connector that i played around with a little but never could figure out what it does
more can bus fun! - i updated the dongle firmware on the android auto dongle sold direct from carperforance and now it has a beta feature to map buttons. somehow it seems to be sniffing the canbus through the android tv box. it has arrow keys, numbers, enter, etc and you use the app to select the input to assign then you press the same button on the car twice- it sniffs the signal and assignes it. I My durango has the button packs on the steering wheel and i was able to assign up, down, left, right and get it to have the android auto respond. Need to play more but i think it actually goes android wide. For example i think the down button on my steering wheel was sending page down to the chrome browser i had open on the box. Pretty cool stuff if they expand that.

Question Screen not working unable to get into the phone

Hi, I need help and looked almost everywhere for answers. For the past few days, I've been trying to recover the photos and videos on my phone. The screen went completely black last week and I've restarted it thinking this would fix the problem. It didn't and now I can't even get past the PIN unlock. The phone still works when connecting with an HDMI cable, but I'm unable to get past the pin unlock.
I tried using an HDMI adapter hub and connected with a keyboard to no avail. The keyboard powered on, but anything I tried pressing on my keyboard the phone didn't respond to the keys, numbers, and all. Also even tried using a mouse.
I also tried using Samsung Dex, but I just couldn't get past the startup PIN.
What can I do to retrieve my files?
A data recovery specialist may be able to retrieve them.
Always regularly and redundantly backup critical data.Another disadvantage of not having a SD card slot as it's data if unencrypted it would by accessible
Thank you for your kind response. Would it be possible to have the screen fixed then I'd be able to have a working phone?
You're welcome.
Perhaps. That may increase the risk of data lose though. If it was me I would have written the lost data off already. I've lost a database that was 30 yo and not replaceable. Some lessons are learned the hard way.
Man, that's a terrible and awful lesson to learn. But you are right, that's the hard way. I'm going to try one last thing, I can't give up, I'm going to purchase a wireless keyboard and pray that I can type my pin in.

You can also connect a USB mouse, but then you have to find out where on the screen the numbers normally appear.

I'm thrilled that my solution worked! I'm now using Samsung DEX in combination with a universal adapter hub, a wireless mouse, and keyboard, and transferring files to an external SSD. I am grateful for the advice provided by others.
Edit: After further exploration, I've realized the solution was even when the screen was black. I can still swipe up and type my pin blindly while using Samsung Dex. (The screen isn't active when not in Dex, but in Dex, it works somehow.)
Edit2: The only way to get past my pin was to blindly type my pin like this the way to get access to my phone data was to blindly accept the access from computer. (I say blindly because I could not see the what I was pressing and it was just through memory that I was able to do it)
Edit 3: If you are suffering from a dead screen issue and are unable to access the data from your phone, there is still hope. But first, you must remember your pin and where each press goes. Although you cannot see your screen, swipe up (this would allow you to type your pin). Type your pin, and if done correctly you have unlocked your phone (although you cannot see this). You should however be able to access your phone through Samsung Dex, see your screen, and access your files. Sometimes Samsung Dex just doesn't want to work. It's okay, now, connect your phone to your computer. You should see your internal storage. If not, then your phone is asking permission. (You can't see this) Simply tap on the bottom right of your phone to OK the permission. I hope this was helpful. Thank you
Some notes; a day before my screen went completely black, the top half of my phone was not touchable (the touch screen just didn't want to work.) I was very lucky the bottom half to type my pin was still working even though I could not see (just through memory).
Kindly change the thread to SOLVED thank you
