Weird Dark Blotches on screen? - Xiaomi Mi A2 / 6X Questions & Answers

Hello! For some reason my phone has these weird dark spots that jump around whenever there's something dark on my phone (Reddit dark mode, twitter, discord, dark spots on youtube/netflix) and I tried to use a screen recorder to capture it but it doesn't show up on the video, so I assume I just have a faulty screen? Or is this a bug with Android Pie? I only got the phone a few days ago, no drops or thuds on it.

It's a known issue that was introduced in the February security update.

Well, I guess I'm happy my screen isn't broken but this also means I don't know how to fix it.. Have they announced that they know this? Once I update my phone to pie (The day I got it sadly) I've noticed so many issues with it, and I can't go back to Oreo :/

People have reported it but no official response from Xiaomi yet. We'll have to wait and see if the March security update fixes it.

Thanks for these details. I almost accepted the update but declined.
It's going to take a lot for me to purchase a Mi A3. Quality control on this device is horrid.

Night shots and Astrophotography Pictures disappearing

Is anyone else running into this issue? The problem started last night, and it happened first on the September update, so I don't think much about it, kinda pissed, sat outside in the cold taking 4 minute pictures that looked awesome just to have them not save to the device. But the problem still persists after updating to the November update.
When I take the picture, I can click the thumb nail immediately after taking the shot, and once the thumb nail pulls up the phone says that it is processing, than just vanishes the photo as if was never taken and pops the previous photo in my camera roll into the thumb nail. This happens with night shots, Astrophotography shots, and selfi night shots. Basically anything using the night shot software is not saving to the phone. I randomly have gotten two photos to save, and I am assuming that is purely luck, as I tried taking at least 100 now while trouble shooting.
Some basic info. I'm on the pixel 4 xl, unlocked (not a carrier device) I'm currently rooted, but had no issues with this last week while being rooted. I have tried clearing the data and force stopping the camera app and also the photos app, and no change. To try everything possible, I even hid root from all Google apps with magisk, and still nothing. My current build is QD1A.190821.014 (TMobile service)
Anyone else having this issue I would be fascinated to hear about it. And of course if you have an idea about how to fix this nonsense that would be awesome. Thanks in advance.
Well figured it out, the November 5th update appears to be the problem.
Down graded to the October 25th release: Google Camera 7.2.011.276470382, andy night shots are now saving to my device.
The November 5th update is one that was giving me issues, it's version: Google Camera 7.2.014.278150624

Interesting, my camera version didn't change when I upgraded to the nov security patch. It was and still is 7.2.011.276470382
Just found the new version on APK mirror, gonna install and test it out and see if I have those same issues.
*Just tested every mode, with and without DNG. Everything saves fine for me. I'm not rooted if that matters. Maybe something with magisk is screwing it up.
Well I thought I fixed my issue, but it started back up. I thought maybe it was the kernel I was running so I went back to stock, and for some reason I am having the same issues. So weird, not sure how this could be only happening to me, it's hard to believe that I have a hardware issue.
I had a similar issue once with motion photos. Do this, take a photo that you expect to disappear and view it immediately after you take it, then verify the date is correct in the file name and EXIF data.

Brightness dependent yellow tint and black lines on the screen

I am facing this issue in my Note 9,
While I am on lower brightness , I am not getting this issue. While increasing the brightness getting these black lines and also some sort of color discoloration with yellow tint also , Could someone help on this?
While on maximum brightness there is no lines are visible. Could someone help on this?
This is what android 10 does to the dispaly setting.downgrade to pie using odin to fix the screen. Back to normal,Basically in android 10 they changed the warmthness of the screen .I'm assuming you are using adaptive display and have the slider set to warm.on pie your screen would look everso slightly pink on warm but on the android 10 the screen looks yellow /brown at warm position on the slider,I made a thread complaining and ended up odining back,They have made it identical to the note 10 in terms of screen colour calibration. It sucks imo as for the black lines you mention I have no idea what that is
Please help me
Please help me
Have you factory reset ??
Next step would be to return under warranty .
Ive allready helped you just odin back to pie it fixes the issue
Happened to me as well. Display discolored showing grainy lines after recent update
I am on Latest build of Samsung Note 9 - India, with March security update on board.
I noticed that my screen shows grain whenever the brightness auto adapts to lower levels, it doesn't get normal until I keep it locked for some time and then unlock.
My phone is 1year and 3 months old however it has no issues in maintenance - no cracks, no falls, no display injuries.
I tried to keep the auto brighntess (adaptive) to off and yet this is happening occassionally when watching videos or pictures or simply pulling down the notification bar.
I also Factory reset it today and I found it is happening right from start - during the setup screens.
I am pretty disappointed something like an update is pushed and that breaks the quality of a device!
It's livable but very annoying when you are showing a picture to someone and suddenly you see the screen becomes discolored and there are grainy black lines all over the display.
I have only one hope if there is a way to go back to Feb or January build of android 10. Anyone else facing this? Please help me.
Have you sorted this issue @aronhq??
Is this a software or hardware issue. I also have this issue and i have been using android 10 from feb and got the issue today only though recently secutity updated 2 days back

I have the same problem at the beginning it was when the phone was warm now the screen is yellow and when I lower the brightness I have lines coming out
Temp fix
As a temp fix i am using oled saver app from playstore and keeping it on serting brightness full and adjusting the brightness with oled status bar so try it
My issue got solved on its own the same day..But now the issue is while watching video, it gets blocked images and slight color artifact when dark scenes play.I don't know whether its due to video compression and i didn't notice such issue previously.

Any update for a possible solution?

Note 9 screen issue!

hello..
As all we know about screen discoloration issue on Note 9 since March... I was able to solve it through AOD solution before the latest security update which is July update.. now after the update the problem is permanent and really annoying ?
So is there any way to just go back a little bit and delete the last patch or downgrade it or something like that ?
Thanks ?
Using oled saver
Same issue here. Before the update, it also worked by taking a selfie with the flash on. Not working since the last update. Final solution was to use the OledSaver App to make the phone atleast uasble.

Black crush / gradient banding issue in samsung note 9

Hello community!
I recently bought a samsung note 9 out of the love towards the note series. But, after 2-3 weeks of usage I started noticing that there are some issues in displaying darker shades of black. The gradients of blacks are not shown properly. Instead, bands are formed in different shades of black. I searched internet and found that it is called black crush. My display is perfectly fine and it is appears like some firmware/software problem rather than a hardware issue. I also saw many people complaining about the same issue with samsung premium phones like S9+, Note 8/9 etc. But it is very surprising that there is no result for black crush or gradient banding in xda forum for note 9.
Please help me here. I wanna know if this is an issue of my piece only or is there anyone with the same issue. (Do check your phone twice before saying no. You might miss to notice it). It is so sad that a premium phone like note 9 is having an issue like this. I also read that even the advanced note 10 also face this problem. So even an update sounds foolish. The black crush isssue is really annoying. Once we notice it, we'll see it everywhere and we cant unsee.
I can't put screenshot to explain as it is a processing problem. You can search google to understand black crush or I can take a picture, if needed, of my display showing it.
If the problem really exists, I think it is high time for Samsung to have a look at it.
Is it on Mar security patch or newer?

Im in the latest security patch (1st September 2020). Is there anyway to get rid of the black crush problem? Would it help if I try installing a custom rom?
I can't tell if custom rom could fix your problem or not but those with display discoloration issue mentioned that their problem haven't go away with newer security patch(Aug/Sep).
If you've no plan in using samsung pay, you could try custom rom but rooting will break this function forever. There are workaround for other functions(at least in rooted mode), but not for samsung pay.

I was thinking about installing another OS. But, I'm not feeling to do it, as rooting permanently trip Knox. Do you know if the black crush issue is a h/w or s/w problem? Is there any fix for this? Will rolling back the OS to any previous version can help removing it?
I don't know if it's s/w or h/w but most people with display discoloration issue(not sure if similar as yours?) said s/w. Better just wait for newer firmware base. Those security patches probably with old bootloader/base that's why the screen issue persists.

It appears to be a software issue for me too, rather than a hardware one. Thanks for your advice. I'm gonna take it and wait for some time for an update from samsung, without unlocking the bootloader.

Question Latest update Camera issues?

My phone popped up with an update the other day. My wedding day no less. It was the one with the July security patch and said camera improvements.
Now it seems like auto focus is broken on my camera. I have tried resetting the settings in the camera app. The wide angle lense looks fine. I've tried 3rd party camera apps and they are the same. One of them popped up a message saying the lens could be dirty but I know it's not.
I'll likely try a factory reset next before I send it back but just wondering if anyone else has this issue. Not sure if it's a hardware or software issue.
Ok so I've read online... Hit it!
Sure enough a sharp tap on the side and it suddenly auto focused still not sure if that's hardware or software but it seems many people on the Samsung forum have the same issue.
Wow...that sounds scary..almost like OIS locked the lens and was not letting go.
Yeah I'm still not sure if it's a hardware fault or what but it can't be healthy for it. I'm glad I'm not the only one but a little worried about it.
There has got to be more people with this issue?!
I am also facing the same issue since the August software update.From my previous experience with note 20 ultra I can tell that is a software bug that can be fixed by an update.But I wonder when they addresses the issue and fix it.

My network O2 have accepted it as a repair request. I have had an email saying they are sending out a REPLACEMENT device. Not my original one repaired... I'm wondering if this means it is indeed a hardware fault.
Same problem here also. Blurry on zoom. Zoom doesn't work anymore. Not bigger than x9.9
Same here since the last update. I'd say odds on 90% Chance software issue rather than hardware.
The July update is the issue I think. Before then no issues at all
I'm nothing this too. Stuck on the the July update here in Aus and thr camera constantly blurry
