[Q] Weird Screen Flicker Issue - Samsung Galaxy Nexus

Hi guys,
My Galaxy Nexus has a weird issue that I can't seem to figure out whether it is caused by software or hardware. A portion of my screen seems to flicker when I have certain apps open. They all have a common cause. For instance when I open Chrome and begin to do a search from the top I notice the drop down results will flicker in sync with the cursor. It doesn't appear that the whole screen flickers. It only seems to be the drop down results which are typically black text on white backgroud that flicker. I don't notice anything similar within all other apps such as the standard messaging app which have blinking cursors. I can also get the same flickering result in my IMDB Movie app while starting a search within the app which will start to display results that faintly flicker. I have never seen it flicker using a screen testing app such as the ones used for detecting dead pixels. I am not sure if this is something has always existed on my phone, but I noticed this about a week ago while still on 4.1.2. I am now on 4.2 and still have the issue. I attempted a factory reset just to see if that would clear it up but it didn't. Has anyone else experienced this or have some insight for the flickering? I wanted to see if anyone has noticed this before I start the whole Samsung tech process!
One additional observation I made is that when I don't notice the flickering within Chrome,it will remain without any issue until I go and start clearing recent apps.
Thanks,
Jay

Sounds stupid but you sure its not an auto-brightness issue? Samsung phones are known to have crazy auto brightness but anyway try clearing the cache for each app that seems affected....check back let us know what happens

Thanks for the response. I have turned off auto brightness and tried manual brightness settings with the same result. It hasn't become worse, but I can't explain it either way. I have tried clearing the cache for chrome and other apps, but that also hasn't improved things. I am wondering if I try flashing the phone with a fresh stock image instead of just a factory reset since that automatically re-downloaded my apps. I have never done any modifications (root or unlock) so I am not sure that would really help. Maybe the screen is beginning to go bad, but I figured it would flicker when using a screen test app. It only flickers on the white background for specific app search results (ex. Chrome, IMDB, and Zillow).
Thanks again,
Jay

So I did some more troubleshooting and I started uninstalling apps to see if I could find an app causing the issue if it was software. For some reason if I am running my XDA Forum app and leave it running in the recent apps list then I don't get the flicker within Chrome or other apps that have search with drop down results. It is just the search results that flicker and not the whole screen. As soon as I swipe away the XDA app then the flickering returns. I tried uninstalling the XDA app and the flickering continues. It is fairly subtle. I could try a factory reset again and not allow Google to re-install my apps and see if that resolves the issue, but it is very strange overall. I swung over to a Verizon store that still had one on display (even though mine is a GSM model)and noticed there unit had similar behavior and it could be a coincidence. It is pretty subtle, but I am confused why the XDA app keeps it from doing it.

Galaxy S3 I747M Screen Glitching

I've read descriptions and watched videos of the flickering issues, and haven't come across what I'm seeing on my phone. It's flickering but not so much of the screen as the elements being displayed, and only in certain situations.
I will take a screenshot next time, but I've found an easy fix for now, in case anyone else is experiencing this issue.
On the home screen while scrolling, icons and widgets will glitch. Either the background will flicker and disappear, or the foreground image or the whole damn thing disappears and reappears. The background also flickers. Will happen in app drawer too. It's happened in multiple launchers.
I've also noticed this happening in the camera app when scrolling through the effects dropdown.
My fix: power down, pull battery.
So far so good. I'm not sure what causes the problem, but I did install new apps right before the glitch began. Uninstalling these apps does not help. Disabling HW overlays and other GPU options doesn't help.
Anyone ever have anything similar?

reflash your rom. If problem persists, flash stock rom. If problem still persists, clear all traces of root and send it in for repair.

Play store/Youtube issues

I'm having this really weird issue with these two apps for a while. Basically I would keep getting connection error in the Play store or on Youtube every few minutes or so, then I would retry and everything would be back to normal. Odd thing is that I can have a browser open in a side window and go to google or any other website just fine while this issue happens. I'm not sure if there's more google apps affected. Hell one time it was so bad that Youtube refused to load for a good minute or so, I opened a pen window for the browser, loaded up the same youtube video in there and it started playing before the app even loaded it (kept giving me connection error).
I have Adblock Plus running in the background so I wonder if that's what's doing this..but it seems odd for it to affect these apps.
Any ideas to fix this?

I don't have Adblock but I have issues with YouTube App aswell. It works most of the time flawlessly but sometimes like you it seems to take to long to load so what I do is close the app fully then launch it again and it works fine, I also had another weird issue of whenever I played a video in full screen and changed the tablets orientation it would dim the brightness to 0% (even changing the screens brightness to 100% wouldn't cause the app to brighten up) and hoy a "small weird box with what looked like signal bars next to it", this hasn't happened the last few times I used the tablet but its just bizarre so deffo something is up with the App that's for sure.

[Q] Somethings Wrong with my S4

Hi guys, I never posted here but am trying to find some help. I've had my S4 for quite a while now, and I just factory reset everything because I kept getting a "Unfortunately, the process android.process.acore has stopped." message that wouldn't go away or let me use my phone without an interruption literally every 2 seconds. But before I even had that problem, there were worse problems as well. There are two things that occur frequently:
1. Sometimes, when I tap on an icon, the indicator light shows up (a glow around the icon), but the app itself does not open. Then, if i tap on it repeatedly, nothing happens. I can temporarily fix this problem by opening up the recent/opened apps list (holding home button) and clearing everything (or clicking on that app if it had been opened). Once cleared, I can tap it again and it would open. As you might see, this can get very annoying and troublesome after doing it so many times. Is there anyway I can permanently fix this so that I don't need to keep clearing the open apps list?
2. Sometimes, when I unlock my screen, exit an app, press the home button, or clear the opened app list (as mentioned above), my wallpaper changes to an app. The app is usually random and sometimes is not one that I had opened. For example, the background of my messaging app or Astro File Manager would show up even if I had not recently opened it at all. I can also temporarily fix this by clearing the recent/opened apps list (as mentioned in #1). After clearing this, the wallpaper resets. Is there any way I can fix this permanently as well?
3. Snapchat and VSCO Cam constantly "stop unexpectedly". I don't know if this is a firmware or incompatibility issue, but it usually works fine. This message pops up once in a while and isn't too burdensome, but is still quite annoying.
Thank you for all the help in advance. I am trying to get the most out of my phone and appreciate any help.
Are you running stock or custom and has anything changed since you factory reset?

It's stock right now. Not rooted or anything at all. I didn't really change much of the device internally, only downloaded a couple of apps, but those have been working fine since the beginning. It is running Kit Kat, 4.4.2. I am currently using Nova Launcher as my home screen replacement.

Random Freezing and Crashing

Hey guys, i love my pixel 3 XL its been great but it has been randomly freezing and locking up, somtimes requiring a restart.
Other time i get the system UI crashed message and then i close it and it works again. Sometimes Chrome or the camera app locks up and crashes too.

I'm getting pretty fed up of factory resetting my phone, the phone started saying it's corrupt so I ended up reflashing it and that issue is now gone, but this freezing issue happens every now and then. You really think a factory reset is worth trying? Or could have something of gone wrong with the reflash?

I absolutely would try a factory reset if things are acting strange for no apparent reason.

If you flashed the factory image it's either a hardware or app issue. Have you tried using the phone for awhile with a minimum of apps? I'd give that a try I don't think a factory reset will do anything if you've already flashed the factory image.

Pixel 3 XL crashing
I have had the same problem. My system UI crashes since new, along with other apps and the phone becomes non-responsive. I thought it was just a new phone glitch that would be fixed with an update, no such luck... I need to do a hard reboot by holding the power button until it reboots. I bought a Pixel 2 XL in August and never had any problems like this. I finally contacted Google about the problems and they RMA'd it. I never root my phones before making sure they work correctly, so this one is and has been stock, unrooted.
My wife and I have the 64GB models in Black (mine), White (hers). She's on her 3rd replacement phone for what seems to be a similar issue.
Symptoms:
When using the fingerprint reader to unlock the phone, it may not unlock for 10+ tries.
The phone's battery drains quickly, within a couple hours of barely any use, her phone might be down to 60-70%
System_UI crashes
Some apps don't seem to load quickly (Like going into messages, you see the app container, and a new chat button, but no messages load for a minute). Or she's had a straight up black screen, and the app wouldn't load.
Takes minutes to call or hang up a call and often takes rebooting to close out the phone app.
It almost seems like something is running in the background that is utilizing the CPU and causing the lag/app/battery issues.
Troubleshooting:
Factory Reset
Wiping Dalvik Cache
Replacing the phone twice through Verizon. The first replacement had the same issues immediately. The 2nd phone showed the same issues immediately, and then went away for 3 weeks since the Dec. 5th Security update, but in the past few days has returned.
Booted in Safe Mode (everything seems to be working fine however extremely limited).
We've also checked the processes and no apps seem to be running that would make any sort of impact.
Running out of ideas

Since the December update, the freezing issues I was having have been significantly reduced, but it still freezes sometimes... I am hoping the January update coming in the next week will smooth out any remaining bugs.
Any of you using a different launcher?
I had this freezing and non-responsive issue. The google rep, replaced it, he determined it is some kind of hardware issue. My replacement didn't have this issue at all (November update). However, the lag/stuttering still persists though. I had replaced quiet a few pixel 3 XL, and i am just getting tired of it. For a $1K phone, we shouldn't get mediocre quality of phone.
So my wife had been removing applications in small groups to try to narrow it down. It seemed for a week or so that she was in the clear and everything was working. Then all of a sudden she got the January update and her phone is still having issues.
Slow responding finger print reader.
System UI crashes
Unable to answer phone calls despite numerous attempts.
It still seems like there is something that is running in the background that is just using the processing power.

Get gsam from the app store, if you don't have it. After awhile see what apps are using battery, app sucker in the app. Gsam is a battery monitor.

Screen Flickering

Hi,
So I offer this phone to my wife this xmas and everything was going smooth until we found this issue:
https://www.youtube.com/watch?v=xYFdyDwuS_w
The bottom screen does this flickering when typing with Swiftkey keyboard on some apps. This one is Doggcatcher but it happens on other apps too.
If I swap to GBoard it does not happen. We're on Android Pie 9.0.
Has anyone found this issue?
Seems like a graphic bug in that specific keyboard.
Please, i need help.
Evaluate for yourself whether it is related to this topic.
Occasionally, graphical glitches appear on my Mi A2 lite, (4/64, Android Pie, December update, locked bootloader, no root, intact system).
In most cases, they flickering all over the screen, and in some other cases they are frozen, as is shown in attachment.
They are completely random and they appear through many applications that i use.
I can not determine the cause.
Does anyone else have a similar problem?
me... on chrome and all app that use webview... during call status bar is flickering... when switch to the camera in whatsapp with swipe to set status... and other
Something similar here, if Facebook Messenger chat head is overlaying YouTube it flickers a lot (only the actual video but the description and recommend are always working without flicker also no problems in fullscreen), less often it happens with Chrome and sometimes YouTube does it without Facebook Messenger even being open (Android Pie Dec. 5) [also it didn't happen for the first few weeks with 8.1 then Pie got released and worked well for some days then this started to happen]
I have that problem , the notification bar flickers a lot and when on video calls, it shows a black flickering rectangle at the bottom of the screen
Hi, I've got the same problem here. For me, the flickering appears when the keyboard is open, and get faster while typing, please does someone know how to fix that?

It is true that it is the keyboard, my keyboard developer is fixing the bug making it do that as we speak but in my case the whole screen flashes black instead of the little box you have
The problem with the flickering screen in some apps like Youtube, Chrome or Instagram can be fixed as follows:
Go to Developer Options and activate "disable hw overlays"
However, the setting must be set again after every Phone restart.

Isn't that bad long term?
"Without a hardware overlay every application that is displaying things on the screen will share video memory and will have to constantly check for collision and clipping to render a proper image, this can cost a lot of processing power. With a hardware overlay each application gets its own portion of video memory, getting rid of the need to check for collision and clipping."
