Screen Flickering - Xiaomi Mi A2 Lite Questions & Answers

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."

[Q] Weird Screen Flicker Issue

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.

Sent from my SGH-I747 using xda app-developers app
I found the real culprit causing this issue:
Display > Auto adjust screen tone
Once this was turned off this problem completely disappeared.

only lag I ever experience....

I use swiftkey keyboard and sometimes it seems to start lagging. I'll type too fast for it to catch up and it's quite annoying. Other times it's perfect and very responsive. It seems like it starts happening randomly. I thought it could be a ram issue but a couple times it's started happening I've closed all apps and cleared ram and it doesn't fix it. I even cleared swiftkey cache. Any ideas? I should mention I type pretty fast.
Two diagnostic questions:
(1) When Switfkey starts lagging, do you also get a lag in the sound-feedback on the stock phone dialer?
(2) Does the Swiftkey delay go away if you turn off sound-feedback for typing?

You mean does the typing sound lag as well or just the sound if I open up the phone app and dial to make a call?
I did a lot of research last night about this and found others with the same problem... Someone said that if you clear your clipboard from the settings in your keyboard the lag goes away.. I did that last night and the keyboard has never felt father. How come that would cause it to start lagging?
Nope, the lag doesn't go away even if I have sound and vibration off. The only thing that seems to have made a huge difference is clearing the clipboard. I don't think it's placebo because it literally hasn't went into lag mode a single time since I did that.
Also, when it would go into lag mode, the keyboard lag wasn't too terrible ever in the messaging app built into the phone however facebook messenger, kik, and Google search were pretty horrible.
After more research I found more posts. Someone said having accessibility option enabled for nova launcher is causing this. I took about 10 screen shots and my keyboard immediately started lagging again. I cleared clipboard and lag fixed. I then disabled nova accessibility, took 10 screen shots, and it DID NOT LAG even with all of those in clipboard. I'm now convinced it's nova launcher causing this issue....

My Google keyboard keeps disappearing

Any permanent solution for that? I can clear data and it works. But it resets everything. And after a few days it disappears again. I can actually type but I see no keyboard.
I had the same problem on my Z Play with stock 7.1.1 (soak test). The Gboard disappaer and goes black. I have then force close in Settings, Apps, Gboard. Then it working again for a while.
Now I have switch to LOS14.1 and the problem isn't come again. Maybe the final release of stock 7.1.1 fix the problem, too?
But I really don't know if it's a rom problem or an app problem.

I get this too a lot. Never happened when I was still using my LG G3, but ever since I switched to the Z Play it crashes sometimes or the keyboard just stays black.

But that's a software problem. On LOS14.1 I have not this issue. But here is all newest now That's feels so good
And would be interested to know if the problem by Motorolas Stock ROM or by Googles Gboard.
And I see that I have gotten the newest version of Gboard with the latest Open Gapps. Maybe it's enough to update Gboard? Otherwise moto has the bug in her firmwares.
Just enable Force GPU rendering on Dev settings and will be fixed

I would say that's the problem is by Gboard. Would try to update Gboard first. Then we would know exactly.
But don't know. Try Gboard update, then we see.
Had this problem also , seems to be solved with the latest gboard update a couple of days ago.
Me too. Started about 2 months ago, When starting Google search the keyboard appeared, disappeared, appeared. I often typed in an area exactly when the keyboard disappeared. Sometimes it seems to have crashed, no keyboard to see, needed to switch to a different keyboard and back to re-enable. Was happening about every second day. Then I found it it is active, but invisible!
All that crap ended last week after an update. Hope all the issues had the same reason which got fixed.
Not all issues are fixed. When activating Google Search bar, the keyboard sometimes still appears, disappears, appears. It's a really bad timing because every second time I start typing exactly in the moment when it disappears for a quarter second, and thereby deactivate it and start something else whatever is under the key I press (maybe the second key press if the first got used by deactivating, dunno for sure).

Question Pixel 6 pro screen glitch

Hi, anyone has this issue with pixel 6 pro. It only happens on video from YouTube and very intermittent. Does not happen to the same video. Have not seen it in full screen or on other apps. Very strange bug or is it hardware issue in which case I should get a replacement

I'd suggest to use safemode and see if it still pops up then, in that case I'd contact Google. Of course you could always try a factory reset, but that's a heckload of trouble and wasted hours...

The hard part is that it happens only once a day or so that I struggle to capture it. So I'd probably have to run on safe mode for a long while, I'll see if I can get Google to replace. Cheers
I've never had that, I'd RMA that if I were you!

I definitely had that happen last week when I was watching Youtube! This was after a factory reset too so I wasn't sure what was happening. Same exact thing, lines flashed across the screen just like yours. I have not seen it happen since or perhaps I haven't been watching enough videos on the phone since.
Have you contacted support, and what did they say? I'm kind of scared to contact them with all the outsourcing now and other stories I've been seeing about them not being as helpful as they used to be.

I'm not sure but am wondering the same thing. I was not able to get a hold of Google support but will try after the new year. If the OP can see it happening randomly I bet it is happening randomly for us too but we haven't caught it again. It looks like those old CRT TV's. I unfortunately was not able to get screen recorder open in time to capture when it was happening.

There is no need to record your screen. you can send google the op recording
I hope google will fix this phone.. I guess that is what you get for being a Tensor early adopter.
I just had this happen too for the first time, happened to quickly to get any recording of it. Also on YouTube as I was adding a video to my watch later. Are you using Vanced by any chance? Maybe it's just the software glitch with that?! Hope there's no hardware fault going on here...

I am using the regular Youtube app since I pay for premium. I don't think its related to any app as the OP said it also happened on other videos.
Also have this happen to me somewhat often (once or twice a day), but it's only ever in the youtube app. I'm using the YouTube vanced app and It's never happened in any other app.

Interesting.....let's hope a fix is on it's way at some point...
Have you guys noticed a graphical glitch in Google photos? When in landscape and the video is paused and you scroll up from the bottom of the screen for your settings, a glitch appears!
It was first mentioned in Reddit.
I've had the same thing, but it appears at the bottom of the screen (it's happened a few times, maybe 5 or 6) - and for mine it was about an inch high. It was really odd - never seen a glitch like that before. usually you can tell if it's the display or software but this was very similar to op's - and it stayed for like 10 seconds. using Brave Browser, not watching a video (pixel 6 pro on december build)
YES YES YES! Thank you for the post, OP!
This wasn't an issue till about five days ago and it only occurs in the YouTube application! It's difficult to reproduce, but usually having a video running, opening the comments section then successively minimizing and maximizing the video (in Portrait mode) can trigger this error.
I suspect it has something to do with a change in refresh rate, since this particular change causes just that.
It's not annoying to the point I have considered turning the phone back, but it's mildly concerning especially since the first time it occurs, you're unsure whether it's a hardware or software issue.
Same here with YouTube Vanced in the exact same Spot, never seen in another app
Try newpipe instead. Hint: no ads
