I bought a new Google IO Galaxy 10.1 about a month ago from someone who attended the conference. I haven't had any major problems with it until tonight. For some reason, the screen flickers so severely that the tab is unusable. I thought maybe there was an app that wasn't compatible with HC3.1, so I wiped it clean in fastboot and reflashed everything to stock.
Unfortunately the screen flicker remains, and turning the screen off and on provides me with only a few seconds to see what I'm doing. I will post a picture after my 8th post.
Anyone have similar problems? Any idea what could have caused it? Since I bought it in a private sale, I don't think I can send it in.
Update:
The screen flicker was completely gone this morning after letting the tablet sit overnight. Unfortunately, upon rebooting, the flickering has returned in full force.
Update:
The flicker, which was more like trying to watch a scrambled t.v. channel, has disapeared on it's own. Very strange, maybe the gpu was overheating due to overclocking.
Problem still exists, unrooting and sending it in.
Thanks for all the input... pfft.
I just experienced the exact same issue for the first time this morning. The entire screens flickers and becomes scrambled which renders the touchscreen useless.
My tablet is in factory form with no rooting or overclocking so I find this puzzling....

I've had my TFP for about three days and I'm getting heavy screen tearing. It shuts down the entire left third of my screen. Every thing goes blank and then I get flickering.
What's the solution to this?
try a reboot or soft reset
Hello,
I've had very similar issue with my screen. Every now and again when I wake my TFP it looks as though it's running in 16-bit color mode. Once unlocked the screen returns to normal.
I've also experienced the screen taring as described above. As with the other issue things usually place them selves after a few seconds. Once I had to reboot to return the screen to normal.
Scary as hell the first time it happened, though I had fried my prime....
Sadly I have not had the chance to look into why this happens or find a fix for it but as it doesn't keep the tablet from working correct it not very high on my priority list.

This.
Here is a helpful video for this procedure
Where did you buy your prime from? Reason I ask if this doesn't fix the problem you may consider the option of going back and exchanging for another
unit.
I did the cold boot and have done a complete factory re-set twice. Neither fixed the problem! Terribly disappointing! I really do like this device but the screen tearing makes it almost unusable!
Would a new software update potentially fix this? I got mine from Best Buy and have a week left to return it. There are none in the stores locally.

Just an idea, does it also show on a screenshot? Maybe if it does it can be fixed with a update, otherwise it is best to return it because then it most likely is hardware I guess.
Here's a screen shot of my problem. It doesn't happen if I just try a screen shoot still picutre.

i've seen this stuff happening with my prime also, but after reboot it was solved..
if it's not disappearing after a reboot i would say the gpu\soc is having troubles (hardware issue)
First of all, that isn't a screen shot. That is video of the screen. A screen shot is taken by the device and saved to an image file so it can be uploaded. You may have something wrong with your screen, which a SCREEN shot would rule out or in.

Just to clarify, I know what a screen shot is and I have tried to capture a still picture of my screen tearing but it doesn't take. I've tried it on everyone of my 5 screens but it only happens as show in my video.

I've seen that problem on several primes. Usually viewing Youtube video's causes this. I've also seen the taskbar "micro jumping" while this is occuring.

Do you have a Micro-HDMI to HDMI cable(Or whatever it is the Prime uses)?
They are about $6-$10 shipped online, but if you have one of these already plug it into a TV or something. If the artifacting still happens, it's the GPU. If it doesn't though, it's probably a faulty cable or circuitry.
Turn off the ASUS 'quick settings'. Also unmount the SD card.
I Believe I've Got It Fixed!
Last night I did a complete wipe of my TFP. I turned it off and then held the volume button down while pressing the power button. I got the tiny text and the two icons. I read the instruction on how to do a wipe, it's very specific and you have to confirm you want to do this. It then wiped all my data and did a cold boot.
When my home screen came back, there was no screen tearing or flickering. I changed
the background and added some widgets to the home screen and brought up the quick menu, but still no screen tearing or flickering
I had to input my Google account and everything else. For some reason, my Google Play Store account doesn't automatically download every one of my apps. So I have been selectively downloading and installing each app and widget. So far, so good. No screen problems.
I took snapshots of my previous screens so I can re-build them from scratch but this time I'll only put one icon or widget on each screen at a time and test for tearing or flickering.
Crossing my fingers that I got this fixed.
Hi Everyone
So I've been having issues with the touchscreen for Kindle fire HDX 7" tablet. I have spoken to Amazon customer service which was no help and the only help they offered was for me to buy a new Kindle which is unacceptable in my opinion.
When I first turn on my tablet everything is working fine with no issues, but after some light usage and maybe some internet browsing it starts to lock up. It almost seems like there's some memory leak issue where the RAM fills up too fast causing the device to become unresponsive. Some parts of the screen becomes unresponsive while other parts of the screen work ok especially when using the keyboard. The tablet seems to be completely responsive again if I press the power button where it takes me back to the homepage but only for like 2 minutes and then starts to do the same thing again. One thing to note is it's not always the same area of the screen that becomes unresponsive.
I have tried doing a factory reset, hard reboot, and even used a custom ROM (CM 11 using Safestrap v4). I am still getting the same issue so now I believe it's some sort of hardware issue but not sure which. I would like to see if I can fix this as I did spent over 240 dollars on this device. Could it be the screen display and digitizer causing this issue or something else? There are no cracks in the screen and I do not believe it was ever dropped. If anyone can shed any light on what could be the problem that would be fantastic.
-Thanks

Hello everyone, this happened just today. I was using my galaxy alpha AT&T and all of a sudden the screen starting glitching and jumping. I was quite shocked because I bought this phone a few days ago. Although the phone is not brand new but the vendor told me that it's completely fine. Anyhow, I pressed the power button and waited for a few seconds then turned the screen back on. This time the screen was fine but after a few seconds of usage the problem started again. Now i read on the internet that this is not a screen issue but rather its associated with phone's charging port but I'm not sure. And another interesting thing is that the screen shots are completely fine and there are no signs of glitching or flickering. Secondly also note that I was experiencing the famous "cannot charge because battery is too cold!" message and I believe that this problem is also associated with the charging port. So please if anyone is familiar with this problem then guide me. Here a video link that shows what's happening to my screen

If you have the screen on the lowest bright setting the flickering will continue. Once I put it back on auto or at a slightly higher level the flickering went away. That's at least what fixed mine.

I've never had encounter this kind of problem. Your problem is too severe. I think it is related to the hardware.
(UPDATE: Here is a link to a short video of my issue: https://youtu.be/YqKW3tU4Fhw)
So I cant seem to find ANY info relating to this issue aside from results for the LG G4, but the solutions for said phone are all over the place. Some are bad screen, some are related to sim tray, some are related to water damage and battery etc. So basically, about a month after buying this phone (KIW-L24 US version), the screen started to artifact and flash in and out randomly. There is nothing that seems to trigger it. I have set the phone down on a table while on the homescreen and watched the lightshow. It is basically a mixture of the problems seen in these videos (Feat. LG G4).
https://youtu.be/gAUkXLR7eQI And https://youtu.be/QstOH66pfiU.
Symptoms:
Screen will randomly start to flicker and fade in and out. I will also get crazy artifacting lines. (Think de-gaussing an old CRT monitor or simillar to what is seen in the second video)
If i see the problems happening, locking the phone and unlocking again will sometimes fix it temporarily. Other times the problem continues after i turn the screen back on.
Sometimes the screen will refuse to come back on. The backlight turns on, and the digitizer responds, but the screen is still black. Making sure the screen really is off, I can come back to the phone a few minutes later and it will turn on. Other times ill have to hard reset the phone (hold power button 10 sec) and it usually brings the screen back to life.
Background:
I bought the phone "used - Like New" from amazon. It came with all the original accessories and even still had the film protector on the back of the phone. I may have noticed these problems after I received the phone, but they really only started to show about a month after purchase.
At first I though it could be software related as I was running CM13 and something could have been corrupted, so i did not just a factory restore, but a full reflash. This didn't solve the issue. Restarting my phone and the reflash did help, but the problem returned. The inability to turn the screen on persists through a reset and I have to wait till the phone boots again to get the screen back. Sometimes takes more than one reboot. This pretty much confirms a hardware issue right? If i put the phone on a black screen, i can see three small fuzzy "dots" in a triangle shape in the top left quadrant. Could the screen have been damaged by whoever owned it before returning it? They are not dead pixels per se, but seems more like areas where the backlight is showing through ever so slightly more. Not visible unless you are on a black screen in a dark room. Ill upload a video showing some of the issues. Any help is appreciated!
im afraid you need a new display brodar...
Seems to be hardware issue. You can visit the nearest service center to get it fixed for few bucks if you don't have warranty.
Yeah that's what i figured, i just needed conformation. I was able to get amazon to take the return even though I was out of the return period. So at least ill be able to get a refund. Ill just pay the extra for a new one this time haha.
One question : Do u have over heat problem with ur phone ?? If u feel ur phone is more than work from the back dont replace . U'll damage the new screen also . Some ppl erported over heat cpu issue with honor ! ;.

Try moving to stock once , if it fixed stick to it for few days . 99% of possible cases for hardware issue .
So better request for a replacement from huawei . but don't mention them that u bought it used . tell them u bought it new
Seems that a lot of people complain about this bug/glitch. It mostly happens with this device, specific to some carrier like s5 t mobile etc. Mostly what people face is flickering with a green/yellow nuance that covers at least half of the screen, and that happens when you set screen brightness on minimum. Some other ( like me ) also get the flickering while turning the screen on or off. So I started doing some searches over the web, and tried all the 'fixes' possible. Sadly to me nothing worked. Some of these 'fixes' are :
Turning off auto brightness.
Turning off adaptive display.
Turning off screen overlay ( found on developer settings )
Also other strange ones like removing your sd card etc. Few people say that these worked for them, but for me it didn't.
I tried booting on safe mode, and the problem was still there. I also flashed official 5.0 and the same. So the only thing left was to blame the hardware. But I was sceptical about this since the problem is not persistive, sometimes it happens, sometimes not. Sometimes it happens on small scale, sometimes it is worse. Also a lot of people say that their devices were working fine and the problem started after marshmallow update. A certain person on an online forum claims that he/ she spoke with samsung officials and they are aware about this problem and working on an update to fix this. Does this mean it is not physical problem but just a software glitch ? Hard to say, I sent my phone to different local repair shop and they say it is screen physical problem. But maybe they just want to scam me and take money ( new screen costs too much )
After going through all these, I just got the idea to try and flash an older firmware, like kitkat. And to my surprise, on official kitkat rom it still does the problem, but FAR less.
So TLDR if you have this glitch and gave up on all the 'fixes' you found online, try flashing kitkat, it might work for you even if it's not a permanent fix.
I'm sorry to bump this topic being that it seems dead. However after my own research and now my second S5 from T-Mobile. I'm at the same point as you. My research states that it's more of an AMOLED screen issue, which after a factory reset and flash of older ROM and such does make sense. However, at the same time it could be an actual issue with the screen.
It's definitely a hardware issue in my case-cold temperatures exacerbate it ie-I have no flicker issues in the summer, but get flicker issues in the winter if my phone cool's down to the 60s. The flicker goes away if I heat the screen.
It seems the lower the temp, the more wattage (brightness) is required for the display matrix to function; insufficient wattage/heat when the screen is activated, and the matrix collapses. This is why it autobrightness tends causes issues when it provides power below threshold for matrix stability.
Easiest legitimate econimical fix is ordering a replacement screen, if you have reaervations about yiur shop doing it, it's a very easy/cheap/simple process to do yourself and plenty of how to YouTube videos.
okay, I will solve this issue for yall. I have an s5 g900t that had the screen flicker issue and also when temps are cold, the screen would blank out till I warmed the screen. I fixed this issue after a year of having the issue. a temp fix which can damage the device was found by accident when I went to change out a broken rear cam. heating the screen with a heat gun during surgery fixed the issue for a while then the symptoms came back. after much much research and testing, I found the amoled screen was the culprit. I ordered a new screen and replaced it. no more issues. I took the old screen and replaced it to my other s5 which is for testing only and the screen flickered under low light and would not come on when cold. so, if you have a screen that is flickering in low light and/or wont come on during cold, its your screen. replace it and fixed. how long the new screen will last? well 2 years later no problems, yet.
FYI, AMOLED screens are notorious for this issue and the manufacture is well aware.
