MTCE - PX5 - Screen interference Issue when data writing to storage - MTCD Android Head Units General

Is it common for the screen to flicker (sometimes quite badly) when data is writing to SD card or memory?
My unit has always done this, like when it does a media scan or if I'm installing a new ROM image, it's as if the storage system is interfering with the LCD hardware.
I recently installed a music streaming app and it is very apparent here, as the song caches to local the screen glitches badly until it finished then it works normally again until the next track.
It's so annoying, does anyone have this or know how I can make it stop?

Absolutely not normal. Send it back if you can.
If not, I have a screen to sell.

Was hoping it was a normal thing or suggested a lose or badly grounded connection I could check
It's not like the example I gave all the time, my screen is normal unless there is a large data transfer taking place, that's the only time it happens. I should open it and check the cables first.
PM me the details of your screen, I haven't taken this apart before, is it a complete unit, screen, and digitiser? are you in AUS?
Thanks

Camera freeze after 3 pictures taken. EVERYTIME!

My Camera locks up after taking 3 pictures. Just freezes on the finished photo and I have to tap home multiple times to get out of the camera then I start the camera up again and it just displays a black screen. So then I have to exit out of it again and open it to get it to take 3 more pictures. Storage is set to the SD card.
Sorry to hear the man. I have been using the camera quite a bit and havent had 1 issue with the camera or behavior as you explained.
Try a different SD card or even format the card as a test and try again. If not next clear/wipe the phone for poss software issue. If not it maybe hardware, remember you have your manufacture warranty from the store if you need it p
yea, that's a bummer. No issues here either.
You can try the formatting of the SD card, or you can simply change the setting to make it so that images are stored on internal storage to see if that makes a difference. If it's already set to store on internal storage, then change it to the storage card. One or the other may be bad.
Doesn't really makes sense that it only happens after snapping a few shots though.
Good luck.
I have had this happen too. I cant use the home button to get out though, I have to lock the phone for about 30 seconds, and when I unlock, it sometimes is ready to take a picture. I have switched my camera down to 5mp to see if it helps, and it did a little, but it still happens. I also had my camera set to internal storage.
Changed to internal storage again and its working so far. Saw another post on the Verizon boards saying the fixed the issue by switching form internal to SD card storage.
This is still happening even after its been switched to internal storage.
I have the same problem, but intermittently

Anyone report this to HTC directly? On my winmo phones, they were MORE than helpful; basically the definition of excellent customer service.
Forums only go so far, ya know?
I have had the same problem off and on, once I use task killer It runs ok again. It can be quite frustrating when you only have a limited amount of time to take a pic. Kids, pets, etc dont exactly stay in the same place for very long LOL. I assumed it was caused by some stupid app I downloaded
FIXED
Fixed ( I think) got a response to the same post on the Verizon forum from an employee.
Factory reset (i know big pain). I guess the camera app/driver was corrupted and factory reset reloads a fresh build of the camera.
Tried it and i snapped about 15 shots rapid fire no problems.
I said that 2nd post from the top lmao
NOT FIXED

Well it didn't work. The camera app locks up randomly now when taking pictures.
It gets worse when i adjust the settings on the camera.
Same problem here. Factory reset did not help.

Camera crashed. Lost everything.

I'm so mad right now.
My camera app crashed even after several reboots forcing a Hard reset.
I lost all my data and the camera app still crashes.
I can't describe how mad I am.
I press the camera button and it shows for a sec. It then immediately returns to the home screen.
I'm gonna contact Microsoft first thing in the morning.
I might lose a job because of this.
The hard reset didn't fix anything. It still crashes .
Can someone link me the he fastest way to get to Microsoft to help me fix this stuff.
I'm seriously going insane. All me stuff is gone and since its impossible to take a backup I'll never get it back.
Die, Microsoft. Die.
You just made me lose heaps of things because of a camera flaw.
Thanks for letting us know:
1. What you were doing when it crashed.
2. What type of phone you have.
3. Whether or not you're using a 3rd party MicroSD card in the slot.
4. What actually happens when it crashes (phone freezes, app just closes, middle finger graphic comes up on the screen, what does it do?)
5. Were you on WiFI, EDGE, 3G, GPRS?
6. Are you sure the device isn't defective (And/or prematurely failing on you? In this case, the OS has nothing to do with it - can happen on any phone running any Smartphone OS)
7. Other trivial information that can cause us to come to better conclusions.
Instead, you plummel us with bad grammar, vulgarities, and a rant that will certainly accomplish nothing due to #s 1-5.
BTW, you should back up all important information on any device. Laptop, Tablet PC, Desktop PC, Smartphone, Thumb Drive, etc. It's not Microsoft's fault if you lose you fault due to data loss. Important information should be backed up and IIRC Windows Phone 7 is capable of keeping the Camera Roll Sync'd up with SkyDrive.
I give you 3/10, though.
Ciao!
You might try Windows Phone Support on twitter. They usually reply pretty fast during business hours.
http://twitter.com/#!/WinPhoneSupport
A side note, if you've got a job that depends on your ability to take pictures, you might not want to depend on a phone's camera and use a dedicated camera.
@Side Note: Still shouldn't matter. Anyone that takes (EDIT) photos for business use with their phone camera should have the SkyDrive Camera Roll Backup/Sync enabled and you can set your Photo Gallery to Private.
The OP's situation is completely avoidable.

damn my camera app crashed too yesterday after i was changing some settings.
i turned off light and changed the measurement adjustment.
it crashed when i tried to focus the object. black screen, crash.
so happy a restart fixxed it, i better dont mess with the settings for some time...
Yeah, besides, Microsoft did not MAKE you do a hard reset of your device.
If you read the manual and understood what you were doing before you did it you would have known that a Hard Reset puts the phone back to its initial state.
You must have also disabled image syncing onto Zune which would have backed up your photos everytime you plugged it in or Wifi synched it. Could have also auto-uploaded the pics to Skydrive and had a lower resolution copy on there.
Can't blame Microsoft for this. Yes, the camera should not be broken, but most times a soft reset will fix any software issues.
Bah, sorry.
I was kinda drunk when I posted this.
I was at a party.
But to answer the questions:
1. What you were doing when it crashed.
Nothing. I tried to take a picture by holding the camera button whilit was still locked.
2. What type of phone you have.
HTC HD7
3. Whether or not you're using a 3rd party MicroSD card in the slot.
No, I did not modify my phone
4. What actually happens when it crashes (phone freezes, app just closes, middle finger graphic comes up on the screen, what does it do?)
It shows the zoom bar on the right, then immediately closes and shows the start screen.
5. Were you on WiFI, EDGE, 3G, GPRS?
Edge
6. Are you sure the device isn't defective (And/or prematurely failing on you? In this case, the OS has nothing to do with it - can happen on any phone running any Smartphone OS)
Nope, there's nothing wrong with it other than that.
7. Other trivial information that can cause us to come to better conclusions.
Not really, I never did anything special to it.
All I did that evening was texting, calling and updating my status on Facebook because the power blacked out, three times.
Ok, so after the third hard reset the camera works again.
But now all the pictures I take are rotated 90 degrees
I think there's definately something wrong with the camera app.

Sounds more like a HW problem to me (wouldn't be the first for a HD7) as it doesn't happen to everyone else.
Yeah, sounds like a bad HD7 to me too. My first HD7 was an awesome phone, if by awesome, the standard you use is how often it simulated Windows XP by crashing on me.
Returned it and got a new one and it's been smooth sailing so far.
Send that POS back and replace, blame HTC not MS and don't do your business while drunk otherwise it won't be the phone's fault you lost your job.
i don't know which is worse, being unable to identify the cause or blaming something else other than the cause

Honestly, I'm actually surprised somebody hasn't posted Die, Badboy70. Die. because of this post, XDA is maturing. Anyway, your Zune auto syncs your photos by default, I'm assuming if you do this for a living, you'd know not to turn this off. So, I'm going to go out on a limb here and say that you're FOS for saying you're losing a job because of this. I'm betting more on you being a 14 year old who's phone is malfunctioning due to a hardware problem and had to come rant about it instead of asking for help.

Your excuse of being drunk just validates the first part of my phone. You won't know your device is defective without a professional looking at the camera hardware. Just becase nothing else is messing up doesn't mean the camera isn't defective. Considering it worked, and then didn't, especially on factory settings leads me to believe this is hardware related, if it even exists at all. I would try to replace the device.
It's more likely to be a defective HD7 ...
Doesn't a hard reset delete all the data off your phone? So instead syncing it to your PC and extracting the photos you decided to delete. It may be MS fault that your Camera app crashed, but its your fault the data is missing. Why didn't you back your photos up on your computer or even to skydrive? Couldn't had been to important if your didn't.

[Q] A Couple VERY Weird Glitches Occurring (Need help please!)

*Originally I posted this in the Help section of the G3 forums but got no help, so I am posting this here*
Hey all,
So I'm posting this thread regarding a couple pretty weird glitches and bugs occurring on my G3, 3 specific ones.
The first: (Probably the least serious but still REALLY annoying) At EXACTLY 12:00AM every night no matter what timezone I set the phone to (I'm in AU on the AEST GMT+10 timezone but it does this at the same time on any timezone) the phone will switch it's WiFi off automatically without warning, reason or explanation. It just goes off and then I have to manually turn it back on. Sure I could use an app such as Tasker or AutomateIt to turn it back on but I don't see why this is occurring in the first place?
The second issue (Most recent): Lately after updating to the V20E firmware for my D855 I've noticed that a graphical glitch (Specifically related to the colour Blue) occurs when there are fast moving elements on my phone's screen (Such as when I move a chat head around on my phone from Messenger, or when I'm scrolling Facebook or my App Drawer fast, there's just a blue box around whatever object/s appear to be moving on my phone's screen. I've not dropped the phone at all, and it has only been present since updating from the V20D ROM. Not sure what could be causing it.
The third and by far the MOST ANNOYING of the issues I'm having, is that for no apparent reason, whenever I am listening to Music with the stock Music player, and I lock the screen (The screen goes off) about 5 seconds later weird stuff starts to happen..
The song will pause, play or even stop completely, seemingly on its own. The "phone" will change songs, artists and sometimes complete albums and playlists completely by itself, with me doing nothing but staring at the lock screen (It keeps doing it until I re-enter the Music app, then when I lock the phone the whole cycle just repeats itself.)
I've done some looking around and careful observations on the phone itself, and it seems that before the weird stuff starts happening to my music, the phone opens Voice Mate by itself, and then if I'm not present, it apparently closes it and then that's when the stuff happens. I've tried everything I can on a non-rooted phone to stop this. I've tried re-installing the Music app, Uninstalling all updates to the Voice Mate and it's packages to the factory version, force-stopping Voice Mate, everything and no matter what I do the phone still opens Voice Mate and the weird stuff starts happening (It's like it's taking commands from Voice Mate to do something but I'm not even doing anything ) It's been doing this since I got my phone when it came with Android KitKat 4.4 (I was on the D10M ROM until I moved to the D20D Android L ROM) and I moved ROMs doing a completely fresh start ( I factory wiped the phone and then upgraded via a CSE flash and put all my stuff back on it manually) and I would've thought a completely fresh start would have fixed it but apparently not... Either it's a bug that's been present for a while, or it's something deeper than the ROM.
So yeah some pretty weird issues, if someone knows what could be causing them, please let me know, especially if you know a way to solve them.
Cheers guys.
I'd do a factory reset for bugs 1 and 2. If that doesn't fix it, then do a clean flash from LG's Flash Tool. Regarding the first one, I think that it may be due to Quiet Mode on your phone? Or possibly even Battery Saver automagically kicking in at 12.
But yeah, backup your data and do a reset. It fixes around 80% of bugs after an update (As a rule of thumb I reset just before and right after an update to avoid any issues.

the WiFi issue seems like its something to do with battery saver/quiet mode (to me anyway). Unless your router is kicking the phone off at that time?

oh and regarding the Voice Mate issue it could be either the jack or your headphones?

Note 4 Suddenly Having a Multitude of problems. Hardware Issue?

Hello, I have had my Note 4 for quite some time now and have not had any issues with it up until the last month or so.
At first it started out as just a hiccup every now and then, an example would be when I play music via bluetooth to my Jeep CD Player, I would sometimes have to turn bluetooth off then back on to get it to connect or reconnect.
Now things are getting out of hand. Here is a list of problems I have on a daily/hourly basis and seemingly at random times. I cannot reproduce any of these problems (except the NFC problem) on demand.
I have noticed that rebooting the phone will clear up these issues (except NFC) for a short time, SOMETIMES. Other times a reboot does nothing to help the situation.
Keyboard Lag
Sometimes when I press the keys the phone vibrates indicating a key press and magnifies the key that is being pressed, but fails to enter anything in the text box/input field. For the record I am using Swiftkey. I have noticed that this happens most often when I open an app via "popup notification." For example, if I were to receive an IM or SMS I would tap on the notification that pops up, which then switches to/opens the corresponding app. It is then I will more often than not have this issue. To remedy this I have to close and re-open the app, sometimes several times causing the keyboard to open and close, several times... Sometimes when I TAP a key, the phone will behave as though I have held the key down or performed a "long press." This issue is not exclusive to the keyboard, it often happens anywhere on the screen and with any app, usually indicating that I have been "long pressing" for about 1-2sec at a time.
NFC Does Not Work
One day while I was at work I attempted to add the office printer via NFC. To my surprise I was unable to turn on NFC via the "quick settings" drawer. In the quick settings panel the NFC icon would light up, as if it were turning on, and then just turn right back off again, this happens consistently. I went into setting to enable NFC that way and I am stuck with a slider that is actually in the "on" position but greyed out, I am unable to interact with it.
Bluetooth Connectivity
I have a JVC CD player in my Jeep, I often use YouTube or Google Play Music when I drive. Usually I do not have any problems connecting to the CD player at first, but after about 30-60sec of playback the audio goes blank. The app says that it is still playing however no audio can be heard. Then it will suddenly come back on after about 5-10sec, and here is where it gets strange. After the audio comes back on after this "hiccup" the playback is fast, as in it is playing at 2X's it's normal speed, makes the vocals sound like chipmunks. This will continue indefinitely until I turn on the screen, unlock the phone, then shut the screen off. Then the audio goes on playing fine. This happens with both YouTube and Play Music, while using YouTube the video gets sped up as well. I also experience issues with connectivity where sometimes at random the phone will just disconnect from the CD player, and refuse to reconnect until I have rebooted the phone, or if it does reconnect I get no audio until the phone is rebooted. I notice that this ONLY happens when connected via bluetooth. If I turn bluetooth off while this is happening music will play over the phone's speaker perfectly normal. My CD player has a hands free feature, and I do not seem to have any issues with phone calls, it's only with music playback do I have problems.
Originally I thought it was my CD player acting up, however in light of the other problems, and the fact that I tested it with my tablet and two of my friend's phones without issue, I don't think the CD player is the problem.
Sluggish/Glitchy UI
Sometimes when the phone really freaks out, the UI behaves very strangely. Sometimes notification Icons will hover above the running app, other times the whole screen will lock in place for a few seconds. Sometimes if the screen is locked up, I will shut it off, then turn it on, shut it off, turn it on. However as I press the power button to turn the screen on and off, nothing is happening, the screen just stays black while the "back" and "recent apps" buttons light up at the bottom. Then when the screen does finally come back in it will flash on and off quickly in accordance with how many times I pressed the power button. While all this is happening, if I hold the power button to turn the phone off, the power/reboot menu will appear without incident. Sometimes when I am swiping to unlock the phone, it does not register the full swipe. Basically it acts/appears as though I lightly touched the screen and moved my finger a half inch even though I have drug my finger all the way across the screen. To remedy that issue I have to SLOWLY drag my finger across the screen and then it unlocks without incident. I have also noticed that when I go to "swipe away" a notification, especially one that has "information" in it, it will swipe off the information but leave the notification there and display the app name the notification was from. An example would be, if I just installed an app (for example YouTube) from the Play Store, the notification will say "YouTube has been successfully installed." When I swipe either left or right to remove that notification, a "white ghost box" or "overlaying top layer" with the "successfully installed" text in it will slide away. However it leaves behind a green box/notification that says "Google Play Store" and that remains until I shut the screen off and turn it back on.
NFC Will Not Turn On
I simply cannot get NFC to turn on, the slider is in the ON position but is greyed out as I mentioned earlier. I would post a picture but I guess there is a 10post rule before I can do that. I have given up on NFC, mostly because I rarely use it, so it's really not that big of a deal.
Initializing the Camera
I use an app called "Telegram" instead of SMS messaging, thus I use Telegram to share pictures with friends. Sometimes, again I am not able to reproduce this problem on demand, the problem comes and goes seemingly at random. The camera will take more than 30-60sec to initialize, while I am waiting for it I am stuck with a black screen. If the camera doesn't initialize, shutting the screen on then off will take me back to the telegram app. I never get an error message or anything. Other times when I try to use the camera it pops on instantly and works flawlessly. Originally I thought this was a problem specific to telegram, however in the name of science I tested it with the default camera app and get the same results.
USB File Transfers
I'm not really sure this is specific to my phone, but whenever I transfer files from my PC to the phone or from the phone to PC, it is PAINFULLY slow. It's even painfully slow when the PC just displays what is in the folder. However I can't say for sure this is related because I never attempted to transfer files until I started having these issues, at which point I thought it would be a good idea to start backing things up.
Gets Stuck in 3G Mode
This happens rarely, not even sure that it's related but I felt that it was worth mention.
What have I done to try to remedy this problem you ask?
So far I have performed a non-root ADB nandroid backup, just in case factory resetting the phone didn't work.
I have factory reset the phone 2 times, I see no improvements.
I have cleared out my SD card/removed SD card
I removed and/or shut off bloatware apps (Yes I tested the phone without removing/disabling bloatware, still having the same issues)
Wiped cache via Recovery
I am not sure what else I can really do to fix the phone, I am starting to think that this is a hardware issue. I should mention that there was no significant event that I feel would cause these malfunctions. System update installed and worked perfectly up until this last month, I have not dropped the phone from significant height, the phone has an otterbox anyway. I have not gotten the phone wet, it has not been left outside, this phone has not seen any abuse what-so-ever. I just started having these problems out of the blue and they seem to be getting progressively more frequent and longer lasting. If I don't get any ideas from here I am going to try to get Verizon to replace the phone via insurance, however I don't have high hopes for that because I have grandfathered unlimited data and this is not the "original" phone that I had when I added the insurance option, so I am not sure it's covered.
Does anyone have any ideas on what could be causing this or anything I can do to correct it or try to troubleshoot it?
Any help is greatly appreciated!

I realize that this is a long post but whenever I ask for help I like to be detailed. If I left out any information that might be helpful please let me know.
Unfortunately, it looks very much like components on your logic board are going bad. Sometimes a few specific things will go bad that don't actually make the phone unusable, but make it act similar to what you are explaining. It wouldn't be worth the money you'd have to pay someone to track down the bad components and replace them. If you really like the note 4, I would just make a full backup with kies while you can, buy a new phone and restore your backup.
All of Kies backups do NOT restore to a new phone! Only contacts, messages and call logs will restore on a new phone. Use Samsung Smart Switch or Helium. Good luck

Question Graphical glitches on A52s (Culprit found)

Update: Found the culprit! When the phone is on a 2G network, it happens always when there is any (voice or data) communication and glitches are stronger when the signal is weaker. It's probably caused by an interference and bad shielding of components. Similarly how 2G network makes buzzing sound in radio speakers, on A52s it makes a mess on the screen.
At least one user (bellow) solved it by RMA - sending the phone to service and getting back new/fixed one.
Update 2: Problem fixed. I sent the phone to service center with description how to replicate the issue (phone must be on 2G network, ideally low signal, data or voice transfer is happening). Got it back after 2 weeks. Report says they replaced the display and also battery for "construction" reason (as they described it) and issue seems to be solved!
To conclude: It is indeed hardware issue and is fixed by replacing the display. If this happens to you too, don't wait for software update or anything else, send it to a service for a fix covered by the warranty!
Since few weeks ago, maybe since last update a month ago (security update from 1st October 2021), I'm randomly getting graphical glitches on my A52s.
It usually happens when I wake my phone after few hours of screen off but today I also saw few flashes even when playing a (graphically not demanding) game.
There is colour noise flashing over parts of the screen. It is usually just few random quick couple of 1/100 sec flashes, sometimes it stays a second and it disappears and everything is okay after that.
I also saw noise not covering the screen but flashing instead of wallpaper... Like there's a corruption in graphical memory, driver or whatever.
It doesn't make a difference whether the phone is freshly rebooted or running a week or two.
Does anybody else have this issue?
Is my phone (the memory, screen cable or something else) dying or is ist just a bug in current system update? I don't experience any other instabilities or problems.
(I'd send my phone to RMA but since I didn't find any consistent way to replicate this, it would make just as much of a difference as locking my phone in a drawer for a month.)
I'm appending mock-up screen shots how some of the flashing glitches look.
Clear system cache, hard reboot.
Huh, I didn't really ask for help, but yeah, that's a good idea with clearing the cache.
I rebooted to recovery and wiped the cache partition.
(I also accidentally hard rebooted when trying different button combos to enter the recovery LOL, so I did both things. In the end I had to enter the recovery using "adb reboot recovery" command because none of the button combos I found worked for me.)
I'll report back in few days whether it solved the issue or not.
Your screen is dying. This is hardware issue
Easy fixes are a good thing...

A possibility as is a mobo failure but no harm in trying a few simple fixes first.
Samsung has been having a lot of issues with their displays this year...
It doesn't really feel like screen itself is dying when glitches can appear under the home screen icons in wallpaper or in the application area with status and nav bars being untouched. But I guess it can be; I have no idea how the image on screen is being redrawn.
But it happens especially after phone display is off for longer period of time. The phone then is quite sluggish, presumably because the system paused or killed some apps and is waking them up. And glitches mainly appear then.
That would suggest to me either a system memory being corrupted or something weird happening in the cache, depending on where these apps go when they're paused/killed.

Factory reset. Before loading apps confirm if ok.
Then be careful what 3rd party apps you load.
If the reset doesn't work, reflash it to a known good version.
If all that fails it's likely hardware.
The most likely cause is a 3rd party app given right to overlap other apps and this 3rd party app has crashed. Uninstall apps in opposite order of installing until problem is solved. Or factory reset.
I have the same problem, sent phone for repair.
In my case, the issue is occurring when phone is on 2g network. You could try going to network and set it to 2g only, check if it's happening, and then set it to 3g and see.
Cheers!

So is it a hardware issue or software?

I have the same problem, and I can't replace the phone, the question is here, will this problem increase and affect the screen more?
Same problem here...but mostly when I am on 2G network (anyone please try and post results)...Thinking of sending phone to service...will see how it goes
Huh, I didn't get notifications for my thread, so I didn't know about all the replies!
I tested different things in last few weeks and I came to the same conclusion - that it only and always happens when my phone is on 2G network. If 2G signal is strong, it's occasional small glitchy line here and there. When the signal is really bad, it just messes up the whole screen - I had my phone ringing with screen being all just noise and mess. So I guess it's probably because of interference similarly how the 2G network connection makes buzzing sound in a radio speakers. Except here it makes a mess on the screen.
Now that I know how to reliably replicate the problem, I'll back the phone up and RMA it after christmas.
i have the same problem from the first day, it happens only in 2g signal ...and only if 2g signal is weak... i sent the phone to Samsung , they inform me that they know the problem and it will be fix ..on another update ...it s software problem they told....from this day i have take 3 updates and nothing happened....the phone still have the problem
Same here, took my a52s to a Samsung authorized repair center, after 3 repairs (the third one being the display change) it seems that the problem is solved. To me, it has nothing to do with software.
So, it's a hardware issue, I face the same problem for almost 2 months, and I don't know what to do
Only solution is to contact Samsung and have it fixed
