Screen fading problem - Android Q&A, Help & Troubleshooting

Hi. I am facing a strange issue with my device's display colour. When I launch the camera app and after closing it, the red colour on the screen semms faded out. But the gallery images are fine. The issue solves after a regular reboot but starts after launching and closing the default camera application. I took screenshots of the both state. They looked same.
My device is Symphony Xplorer Z5 Pro (local Chinese phone from Bangladesh) with Android 5.1 and an AMOLED display. Please help me getting rid of the issue. Thanks in advance.

Blackview A5 Green Screen flickering while playing videos

Hi guys,
I just bought a blackview A5 to find out what you can get for about 45€ It's incredible fast and everything works quiet well except playing videos. When I'm playing videos in an app like youtube or tagesschau (german tv channel) I've got a green flickering in the picture, especially if there are a lot of blue areas in the picture. It's like blue area become green then switching back to blue then green again and so on...It's looks a bit like an error in the video driver or video codec...I tried to update the firmware...but still same problem. Does anybody has an idea how to solve the problem? Do you think it's hardware related?
On developer option. Turn on disable hw overlay on developer options. If dint work turn off completely developer option. The flickering issue will solve.
Didn't work for me! Have the same problem.

S9+ Screen Distortion Issue while Scrolling PDF in Night Mode

Hi guys, I am having a problem with my Galaxy S9 Plus. When I open a PDF in Night mode, while scrolling there is some deformation on the screen - in the video (link shared below), there is a grey frame which deforms and 'shrinks' while scrolling up and down in the PDF.
I've explained the issue properly in the video (jump to 0:27 in the video) whose link is given below. Kindly help me out in solving this issue as soon as possible and please check if this issue affects your device or not. Thanks.

Mine is the same; I think it's normal AMOLED behavior: https://forum.xda-developers.com/pixel-2-xl/help/lagging-black-pixels-scrolling-dim-t3696188
My guess is that it takes longer for a completely black pixel to turn on than for lit pixels to turn off or change their brightness.

And I don't need to 'dim' the lights to reproduce the issue, as it is mentioned in the link you've shown. It feels really strange and unexpected from an expensive device like the S9+.
EDIT: To be more precise, the grey frame deforms and SHRINKS in size while scrolling.

Stock camera app crashing

I have a little problem with Redmi Note 9 Pro that my dad have.
For some unknown reason stock camera app started acting weirdly. For example after taking photo it freezes for a moment and then crashes but the photo is properly saved and you can open it in the gallery app.
What is more you cannot switch to macro or wide lens cause that makes app to freeze.
I tried to wipe app data from application settings menu and I updated the phone to MIUI 12 hoping that this would solve the problem.
Unfortunately nothing changed.
Does anyone know a way to reinstall this application hopefully without rooting or unlocking phone?
Thanks
Something I found in my armor x5 is the camera does what you state when screen rotation is active. Try disabling screen rotation, this SHOULD fix the prob.
