screen stutter, complete loss of touch. - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Been using the phone for the last 12 hours and I noticed something towards the end of my use last night.
The screen seemed to become unresponsive. And when it would work it would start to make its own input when scrolling and opening any app or link my finger would drag over while scrolling.
Changed refresh rates, changed resolutions, even seen if the blue light filter was the issue. Nothing.
Almost seems like the screen drops frames when scrolling, like it gets caught on something.

New development. Fingerprint sensor doesn't respond at all and inputting a pattern is damn near impossible. Going to try removing the screen protector to see if that could also be the issue

Did a factory reset
Issue seems to be where the finger print scanner is
It's almost like a dead or unresponsive zone.

Sounds like a factory defect, better have it replaced if resetting didn't worked.

Small video showing when scrolling over the fingerprint reader, the screen almost loses input

Defect.

Samsung has been little help lol. They want me to send it in for repair instead of an exchange. They also said to just order a whole new one and return the one I have now except the black 128 is sold out

Sounds like Samsung support LOL...sorry you're having issues

Did you remove the factory installed screen protector? Maybe it's the cause of the issue

Return that pal, that doesn't sound good at all.

one of the first things i did to trouble shoot. still having the issue. sometimes the screen completely loses all touch registration and it doesnt even know im trying to swipe or push on things. just realized it did this also after tmobiles new software update.
im still waiting here to hear back from samsung on how they are going to fix this issue

The same thing happens to me. Pulling down the notification shade seems to be the only thing that still works. It seems to goose the phone and it starts working again.

Test using the *#0*# diagnostic menu and use the Touch test.

Less responsive touch screen at random times

It seems the touchscreen of my Desire gets less responsive at random times. Anyone else who has this problem as well?
The touchscreen of the Desire is very sensitive in most cases. But it sometimes (randomly) becomes less responsive. I have to give more pressure for the screen to register the touch. This is especially annoying when typing an e-mail or text message.
But for example: when sliding between the screens at the homescreen (Sense), you have to barely touch the screen to slide. When my 'problem' appears, I can actually feel and slide on the screen but nothing happens. When applying more force it does work, but is not as comfortable...
When I reboot the problem seems to be gone for a while, but at some point it becomes less responsive again.
Obviously I have tried uninstalling apps and widgets and see what happens then. But the problem remains. Hard reset/factory reset appears to be working at first, but again after some time the screen becomes less responsive again. This can be after a few minutes or after a few hours. The only way to 'solve' this is to reboot the phone again.
So! Is there anyone who is experiencing the same problems? Because of the factory reset (and obviously not installing any apps after that reset) it seems to me this is some sort of hardware problem.
Any takes on the issue?
I only get such a problem when my hands are sweaty or sticky and when the screen is smudgy. I'm a cleanliness freak though so I naturally keep my hands and the screen very clean avoiding this problem. Otherwise everything is pretty darn consistent on my side... except for one oddity.
I struggled with this phone for months and then gave up trying to type or even just use the touchscreen while it's laying flat on any surface. Most of the touches just never registered, honestly. Even when applying a lot of pressure. Until last week, quite unexpectedly, the touches started registering perfectly. Just as good as when holding it vertical. I was quite amazed and baffled at how something just changed automatically to improve it significantly. The only other observational change in sync was that some apps that kept changing the phones layout based on the way I'm holding it even when I had disabled this feature (like the Tapatalk XDA app) have started working correctly as set now. Just all of a sudden.
I haven't made any setting or config change. I did root a while back but unrooted very soon after by flashing the stock T-Mobile ROM and things were still as bad as the beginning. That's something like 2 months back.
-----------------------------------
- Sent via my HTC Desire -
Ok, weird!
Since I am able to reproduce this with and without installed software (hard reset, no sim, no sd, no nothing) I can only assume it's some sort of hardware problem.
So off to repair department it goes! Thought I'd post it here and perhaps someone would have a solution saying:"Oh! That's this or that". You never know
What I found is sometimes it's unresponsive but it's *puts on black roll neck and jeans* the way that I'm holding it.
I think if you squeeze the phone too much it registers a touch on the side of the screen. Also so times when I'm using it one handed the ball of the bottom of my thumb touches the screen and this is registering, making the rest of the screen unresponsive.
I'd consider this to be the problem first (as annoying as it is). I used to have the 2nd problem on the iPhone, but not the first. It's a bit upsetting but I got over it.

Are you using a screen protector at all?
Since you have the same problem after performing a hard reset, maybe you should consider taking it back to the vendor for a warranty repair or replacement as it could be a faulty digitizer.

[Q] Mytouch 3g Slide Screen Issues ? (WARNING : EXTREMELY LARGE PHOTOS)

So recently my mytouch has been getting worse and worse. I'm not exactly sure if it's me or if it's the stupid phone because it's been degrading over time for some strange reason. First of all, the camera is **** for some reason, this is my second replacement phone from T-Mobile and it's extremely blurry for some reason(apparently it's a common problem but not common enough apparently for the tmobile representatives I've met with have seen before). Secondly, it's been becoming unresponsive at times although i kill my apps after i'm done with them(I probably only have internet, and facebook running most of the time). Third, ever since I've factory reset it, it's become very glitchy for some reason. One of the problems is that I would close the physical keyboard but after sending a text and all of a sudden the screen goes black and the only thing to fix it is to hit the power button and press it again to get it off of sleep. Another problem is after i send a text i close the keyboard and the screen repeats but the location of buttons is still where they're suppose to be on the screen.
Pics of what I'm talking about :

Third Problem(Glitchy screen)

As you can see the buttons are on as the phone is on but the screen is black and unresponsive, i realize i can still go to apps while like that somehow but to fix it i just hit the power button which shouldn't be happening though
Fourth(Repeat Screen)

As said before unless you didn't read this happens after i send a message and close the physical keyboard...

Dude.. you dont need pictures, and if you post them.. resize them first.
Make the thread want to be readable, like-able. Ask yourself, would you read this thread?? and with yellow highlights that no one can even see????????
You also need to post if you're phone is stock, what rom you are on, what version..

This is a stock version, I updated the phone to 2.2.2 but i factory reset it and now it says i have 2.2.1 even though i have 2.2.2 features like Wifi Hotspot,Wifi Calling, and images for contacts on messages...
im not sure, i havent had stock phone in a lonnnggg time..
Hopefully someone else can help you out

This is a hardware problem (the repeating screen) that seems to be happening to many people. (it happened to me before which is why i replaced my previous slide). After my 2yr contract is done, im gonna stop getting phones with keyboards because this also happened to my previous htc slider phones

So it's actually because of the sliding part of the phone ?
I'm not surprised, this phone was pretty cheaply made imo, literally a piece of crap :\

Oh I see, well I tried to get it replaced but HTC was a bit suspicious when they wanted my credit card before anything ......
I have the same issue with my phone
As I was looking at your photos I realized I have the same issue going on with my phone. Does anyone have suggestions on ways to fix it? Personally, I do not believe it is a hardware issue. I do believe it is more of a software issue. That update that HTC offered is definitely screwed up! Ever sine I updated my phone, all of these problems started. This problem did not occur beforehand! My phone was working fine - before this "software update."
Same Problem
I had the same exact problem with the Repeating Screen (and completely agreed about the camera lol). Yesterday I tried demonstrating to my friend the problem, and permanently blacked out my screen. Now, the phone works in the sense that it receives calls, the home keys light up, and the camera still takes pictures. However, with no screen to select any options or perform any functions, the phone has been rendered completely useless. I, too, would like to figure out what the problem is and if there is any possible fix.
Sorry I couldn't be of much help. Just know you're not the only one lol
My girlfriend had the repeating screen issue back in May/June of this year. It was more than likely a software issue, because it became incrementally worse as the phone opened and closed until it came to a point where absolutely nothing could be done when the phone was moved horizontally.
I had T-mobile replace the phone at the time. Unfortuntely an idiot I work with who was supposed to mail it back didn't, I got stuck with an extra $360 on the bill.
Worked out paying for the phone with them yesterday morning, this morning my girlfriend messages me to let me know the screen is acting up again.
Potential Fix?

I would recommend replacing your flex ribbon. It worked for me, and from other threads I've read, I believe it's the cause of these issues. It's a pretty easy fix ( coming from me, who's far better at breaking electronics than fixing them, lol ).
Here's the flex ribbon that I bought off of Ebay ( it's the cheapest I found and it comes with the tools too ):
http://www.ebay.com/itm/170647168235?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
And here's a good video on disassembling your Espresso:
http://www.youtube.com/watch?v=-jgFHuVWlig
P.S.: I'd recommend being more delicate than he was with the volume ribbon though, as mine seemed very frail. Also, this video is for replacing the digitizer, so you only need to follow it to get to the flex ribbon.
A month ago, I had issues very similar to the ones you posted. Sliding my keyboard out ( in any way but gently ) would occasionally split the screen or freeze the phone. Even without using my keyboard, the phone would occasionally freeze while "settling" after the boot animation, and sometimes even during the boot animation. Slowly, those "occasionally"s become more and more frequent, until my screen just went black one day. The phone still seemed to work ( lit up when turned on, made sounds, etc. ), just the screen seemed dead. Figured that I was having a combination of software issues ( the random freezes ), and hardware issues ( split & black screen ), but replacing my flex ribbon suprisingly fixed everything.
This is what worked on my MyTouch 3G Slide
i just keep sliding the phone. and turn off the screen then turn it back on. but not turning off the phone.

Touch screen issues?

Hi,
I have a UK sim free model. It sometimes misinterprets a tap or adds a phantom tap. Its not terrible but I'm sure mine has a issue. A quick Google and a tweet tell me I am not alone. Anyone else seeing this? I could return but I'm dubious it's hardware related...just not sure if it's worth waiting for a software update...

I have same issues with my g4 here in the US.
Unfortunately same here, on a G4, korean model F500S.
I have the same issues on my G4. So probably returning it won't solve it. I notice it the most when I am scrolling in Facebook or web pages I will open a link accidently.
I have the same, occasionally it just won't respond to some taps, i find just pressing the standby on/off button quickly sorts it but it is very annoying.
same here in israel, sometimes do not respond to double tap on lock screen to wake the G4 up
im sure its a software issue, prolly the LP 5.1
Are so you guys using screen protectors? That was the issue for me with g3 and g2.

I am using the out-of-the-box protector on G4. So the thing u mentioned was it with this kinda protector or after-market glass protector?
Try...SGS Touchscreen Booster - Google Play Store
I have run into this same problem with my Verizon G4 (VS986). Many of my taps have gone unrecognized.
I did find this.... http://forum.xda-developers.com/g4/help/fix-touch-screen-registering-touches-t3128518
I tested the software that was recommended...and IT WORKED!
Give it a try...can't hurt!

Okay, I was able to replicate my bug. It happens after playing a game and stops after some time. Turning autorotate back on and switching back and forth from landscape view fixed it.
Hey guys.
I was searching the forums for a fix that solves the phantom/ghost touches I'm getting frequently on my LG G4, H815 model.
Sorry for the long post but my case looks a little more complex than the ones I've been seen in here.
In my case, that's how it happens:
I receive several multi-touches at the same time, usually when Data is enabled. Sometimes it starts right when I switch from Wi-Fi.
It happens often when I'm driving and using Location+Data as well, which drives me crazy. I does also happens (like another user mentioned in this thread) when scrolling down a feed (such as on Facebook) and it suddenly likes/shares a photo/post. It also drives me crazy! And there is also the case where it taps the keyboard and send crazy typos on chat apps when you are real-time texting someone! Another hassle is right after using the camera and opening the gallery to show someone the taken photo...it suddenly scrolls the gallery and open another photo. I just can't make it to see the taken pic. Therefore, I really wanna fix this so bad since it happens every time I need something right away.
A workaround that's been helping, though it's a pain:
I found that pressing the On/Off button and giving it a few seconds will return it to a normal state. The problem is when it happens while I'm driving and are supposed to take an exit/make a turn at the moment. There are some other cases where I'm into something and giving this few seconds is not an option.
Trying right now:
Someone suggested in this thread to use the SGS Touchscreen Booster. I'm giving it a try right now.
Important notes:
This issue has been happening since I got this phone on November, 2015. We got this 6.0 update recently and I was hoping that it would fix it. It didn't.
I have an after market screen protector that I applied in order to see if the issue would go away. It also didn't.
I have been searching about a digitizer replacement but I don't think is a hardware issue, since it just doesn't happens when I'm only on Wifi at home with Data disabled. I believe that the problem is the Data connection that triggers smth.
Any thoughts?
Does anyone have any idea or have experienced the same scenario before? Any thoughts on my guess of data enabling triggering the ghost touches?
Sorry for the long post and thank you so much for reading it.
I think it's both, its hardware and software, LG tried to fixed it but it makes it worst. You can solve the problem for few seconds putting your five fingers at the home menu, It goes crazy and after it stopped making ****. Anyway this phone is great but all the problems make it ****.
I am going to use this thread even though I think my problem is not as serious as yours are.
My problem is that touches are registered, but no action is taken.
For example. Quickly tapping on an icon on the home screen will highlight it, but it will not open the application. I enabled the option in Developer mode to display the touches and the touch is registered. It's just that the app will not load. If I click for a tad longer - it loads. Happens on both stock Launcher and Action Launcher. I have not noticed it happening outside the launcher.
I read something about a keyboard update, but in the Update Center I don't have anything related to the keyboard.
The icons I see it happening with are located in the lower part of the screen.
I am almost sure that this is a software problem, but several updates have not fixed it. Currently on v20d.
Any suggestions or ideas?
After a few more testing and monitoring, I found out that the ghost touches only take place when I'm on LTE.
And even more weird, while driving through some specific areas when I'm commuting.
It's just so weird to think that some towers may send a LTE signal that may cause the ghost touches.
At home, at work, wifi or data, it doesn't happen.

Fingerprint sensor not working occasionally

I've been recently getting some instances where I would lock the phone and the fingerprint sensor won't respond to my finger.
This really started when I changed my lock to pattern swiping. Anyone have the same issue? I rebooted and changed it back to pin lock and it seems to be working all the time again, but I don't know what caused it in the first place.
Thoughts?
How many fingerprints do you have saved? I have 3. 2 of my left index finger and one of my right. 95% of the time I use my left. Set up several and see if that helps. Move your finger all over the sensor when setting it up so it gets a broad picture of your fingerprint

It's not that it doesn't recognize my fingerprints, but it doesn't recognize fingerprints in general. So when I put my finger on it, it doesn't do the double buzz, it's just non responsive.
this happened to me yesterday several times. And i received phone yesterday... . I have two prints. Left and right index fingers. It didnt fail, just was as my finger wasnt in the reader
MDB08L
experienced the same thing this morning. phone was plugged charging and finger print would not detect, had to manually hit the power button then it worked. i find there are a lot of issues when the phone is charging though, screen sometimes becomes very unresponsive while charging. i think there was a similar thread about that as well.
Just started having this today as well. Sometimes doesn't acknowledge fingertip at all; works if i press lock button to wake the screen. Kind of a bummer, otherwise very satisfied overall. Hope it's just something that can be ironed out with a software update.
---------- Post added at 11:58 PM ---------- Previous post was at 11:52 PM ----------
Nothing out of the ordinary installed. Twitter, Instagram, Dropbox, etc. Nothing to interfere with lock screen. I do use pattern unlock.
EDIT: Will try PIN unlock instead of pattern for a while to see if it acts any differently.

Any luck? I did a system wipe after unlocking, and flashed new factory images but still happening.
No luck. Still happening either way. I'd say maybe 10% of the time, fingerprint unlock works correctly. The other 90% I have to wake the screen with the lock button first. Sometimes after trying fingerprint multiple times, when I press the lock button and the screen wakes there is a little message at the bottom that says "Fingerprint hardware unavailable" in red where the little fingerprint icon usually is. But then it immediately changes to the fingerprint icon and it works fine.

I was able to find a bit more about this issue. When it happened again, I pressed the power button and quickly checked the fingerprint icon at the bottom of the lockscreen and it turned red and said "fingerprint hardware not available" for a split second before turning white again. I searched that error message and got this thread https://www.reddit.com/r/nexus5x/comments/3pm3lv/fingerprint_hardware_not_available/
I'll try wiping the cache and see if that helps at all. If not, I'm going to RMA.

I'm not much of a tinkerer, but I'll give this a shot. If it clears it up then okay, but if it happens again I'll probably RMA too. Not willing to put up with such inconsistencies on a brand new phone with such a highly touted feature.
Unrelated, this is actually already my second Nexus 5X. The first one I received would not take a charge, and I didn't have another USB Type-C cable to test, so they sent me an entirely new package. If wiping cache doesn't do it, I'm really not sure if I should bother with a third Nexus 5X. Kind of disheartening. I really enjoy the device otherwise.
So far so good for me, Let me know how it goes for you!

I chatted with a Google support rep today, describing the issue and sending links to other message boards that are discussing this topic. He had me restart the phone in safe mode and sent a follow-up email, asking me to check back in after a few hours or a day or whenever, and let him know if the issue happens again. This was about seven or eight hours ago, and I haven't had the fingerprint sensor fail once when pulling the phone out of my pocket. It seems possible that a third-party app is interfering with the sensor's ability to function when the device is locked and the screen is off. I haven't installed very many apps, and they're all mainstream ones that everybody uses. My next step may be to factory reset the phone and stick to stock install for a day or two, then maybe add apps like Twitter, Instagram, etc., back one at a time per day and see if the issue returns. If it is a software issue, I don't think an RMA is necessary.
EDIT: Well it just did it, never mind all that

Lots of apps updated in the past week. The problem hasn't resurfaced for a whole 48 hours now. Hoping I can put this behind me

That's a bummer. It actually happened again today for me too.

I've spent the past week emailing back and forth with Google tech support, sending in bug reports, even sending a video of the problem happening (and showing the fingerprint sensor working immediately after pressing the lock button). They've determined that the fingerprint sensor hardware itself is fine, and the problem is that instead of waking the screen it's telling the phone to go into Doze. I'm still sending them bug reports, and they're trying to replicate the problem on their own Nexus 5X to determine what (possibly an app?) is causing the problem. I'll report back in with any more information, in case anyone else has the problem and ends up here.
It happened to me too, stock phone, no third apps installed. I will keep an eye on this.
off-topic: the discoloration of the back of the phone it's very bad!

I believe it's not the hardware as well. I've noticed that it's mainly when I get notifications from something that the sensor stops working.

Did a factory reset, and the problem came back almost immediately. Google tech support wanted me to reinstall OS entirely, but I don't have the right cable (type C to type A) to hook up to computer, so they just gave RMA. Got the new one on Friday, so far so good. But then, with the last phone, the issue didn't appear until after a week or two. Fingers pressed. Tech support really seemed to take my case as a rarity, and they were unable to recreate it with their own device. Here's hoping it's just limited to a few devices.
P.S. Off topic, but Google support wouldn't give me anything for the Black Friday deal. I asked multiple times in multiple ways. Oh well.

Ghost touches in upper third of screen

Hi.
My Z1C seems to have a similar case of faulty display as described in some other threads here, but actually a bit different. The phone is stock, not rooted, running 5.1.1
Whenever I do something, there are ghost touches in the upper quarter or third of the screen. They only happen when I am not touching the screen myself. It happens no matter what I do. When I browse internet, it clicks links, when I scroll contacts, it calls people, when I am on facebook it gives likes etc... It seems like the more demanding task the phone is performing, the more ghost touches.
I turned on the developer settings and the "show pointer location" option, which leaves track of the last touch on screen, so I can research the issue.
I found out that when the phone is on home screen, it happens very rarely or not at all - the track of my last touch stays until screen turns off.
When I jump into the touchscreen service test, it does not happen at all. I can draw a line around the whole screen and it stays higlighted indefinitely.
In lock screen, it also doesn't happen.
I tried it in Sketch and it confirmed what I thought, when I was just sketching, from time to time a dot appeared in the upper part of the screen, but when the phone was downloading or installing in the background, the screen literally had seizures. I touched and released and then a storm of dots started to appear around the top part of the screen. It stopped after 5+ seconds, and after another input from me, the screen got another fit, drawing more dots.
I don't have any experience, but I think that since the problem doesn't happen constantly and it doesn't even happen at all in test mode, it could be a SW mistake.
I have found this thread https://forum.xda-developers.com/showthread.php?t=2691849 and I'm willing to try, but 1) my phone is still under warranty and 2) I have never done a root so I am not too eager. Do you think I should try that? Or has anyone found another solution for this problem?
Thanks.

As You have warranty, I would strongly suggest that You go for a repair. I had the same issue in beginning, ghost touches appearing randomly, going away only after reboot. I was rooted and xposed, so went full stock without restoring any apps or data from internal storage, yet the problem remained, thus ruling out the point that it was software problem. And then after a week or so, that much part of screen stopped responding to touch entirely. You can see details over here, Another user had same problem as Mine and had the same end result,
OK then, I'll go for a repair. Thanks for the tip.

I am having exactly the same behaviour as you described .
Ghost touches happening on the upper part, and triggered when a demanding task is running.
Actually I didn't realized completely about this, I thought it was just random, but right now after I saw your post, I tried an app similar to Sketch while upgrading apps or playing a video in the background. And dots in the upper part start appearing crazily.
Did the phone repair solve your problem ? Mine is not in warranty, so I'll have to pay for it.
But also in my case, before this thing happened, I got some water damage and that upper quarter of the screen stopped responding.
After replacing screen+digitizer I got this very specific behaviour you described.

In my case, I realized that I bought (probably) a badly re-fitted phone. Display's backlight was visible around screen panel edges, where I'd say it shouldn't be visible at all. I decided to return the phone and got a refund.
Sorry for not being able to help you.

Ok. The aftermarket screen I got has that issue with the screen edges also. Very probable you are right.
In my case I water damaged myself. It seems that after 2 years of intensive use, waterproofing is gone, by accumulation of slight hits or so, never had a single crack on the screen. I read many posts reporting this happening, even with much less use time.
Too bad, I loved the phone, but I'm afraid that sending it to repair will mean to change the PCB or similar for a complete fix, which can come to a ridiculous price.
Seems it will be time to move on...
Yeah. If you want it fixed properly, you'd need to send it to Sony, and for the money it would cost you, you can probably gen a new phone. Sadly, similar phones aren't made anymore.
