Rare issue with the default launcher going black - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

I was listening to music on my 9t pro and when I was trying to turn on the screen it seems it didn't work but then a black home screen appeared with some simple apps like phone, message with black wallpaper and in the middle between the bar an hour said "no data".
So I was wondering what happened because I can't find an answer

[Q] Freezing black screen ?crashing apps ??how to find out which is cauing this

Hi there.
I recentlt bought a Galaxy noite, and successfully rooted it and installed RocketRom 7.
All good. Very fast and enjoyable experience of use.
Unfortunately I am being plagued with regular 'freezes' of the screen (where no input is accepted for a short while ~15 secs) and black screens (where the notification bar is visible but nothing else). It appears to be on switching from one app to another. The only app that I've noticed regularly triggering a problem is SimiClock widget now I've set it to take me to the stock Clock app on tapping. Other than that it seems to be pretty random and widespread.
I have Apex Launcher installed- is that known to cause this problem?
Is there a way to identify what is causing this and eliminate it?
Cheers for any responses

[Q] Notfications - Screen turns on

Hi,
I'm mainly following the
[ROM][M7UL][JB][4.2.2] CyanogenMod 10.1 official nightlies
thread, as I'm currently running the latest CM 10.1 nightly. The LED on the HTC one is very limited and only has two colors (red and green) as per HTC website. So I was wondering if there's the possibility for a different kind of notification? Examples could be:
- Screen turns on and shows a message about the app that caused a notification.
- Screen turns on in a rhythm to only display the status bar and the symbols of the notifications.
- The buttons (back and home button) blink.
I tried to search if a similar discussion has already taken place, but the search didn't work and I gave up after manually looking through 5 or so pages of open threads.
thanks,
aspast.
Are there no possibilities for this?
If a notification pops up while the screen is locked and the whole screen remains black except for the little notification icon or the whole notification bar. This could be an optional notification feature for CM or similar.

There are lockscreen alternatives in the play store that allow this, Holo Locker for one. That allows the screen to turn on and show banners, similar to iOS but I know the stock Android lockscreen doesn't show anything other than in the status bar ... Even more frustrating is the fact I have to unlock my device to answer a call. There are so many good features in Android but the way notifications are handled is terrible IMO.
there already are some kernels that have the back and the home buttons flash glow when a notification comes up.

Galaxy Camera EK-GC200 losing wallpaper

Since having the camera, the wallpaper I choose never stays for long and the camera reverts back to a gradient blue on home screen and lock screen. Every morning when I check it, see it has gone back to the default blue.
The issue occurs whether I use the other available internally stored OEM wallpapers or alternate.
Any ideas?
Same thing happens to me, but my Google account also disappears. Sometimes it happens at the same time, and sometimes it's just the wallpaper. The interestng part is that when I used a completely custom wallpaper it never happened -- only when I used one of the stock wallpaper choices.

Minimizing call screen - no root - Asus Rog Phone II

Just got this phone yesterday and noticed that I can't do anything while receiving a call, there is an "always on top" screen that won't go away by pressing any of the buttons until you hang up. This is really annoying since it completely disables the phone. Let says you are driving using google maps and somebody calls you, you will miss your exit for sure, or you want to check a text while talking on the phone, not possible... Already tried to disable the phone notifications, as well as trying all the available options ( for notifications), also tried with other phone apps and with SystemUI Tuner app all with no success.
Is anybody else having this issue? I'm happy to provide any info you guys might need as well as do any test. Currently using Nova launcher,
Android version 9,
Security patch Jun 5 2019.
Software info WW_16.0622.1906.19_0
Extension ROM 1.1.93
Maybe because of Nova Launcher. It is actually kinda weird. What firmware is installed on your ROG Phone 2?
I'm also on WW_16.0622.1906.19_0 and when I'm in a call I can just go home or use recent apps while in a call, mine looks like this, note the green bar at the top of the Play store screenshot.
I also use Nova launcher.

Nothing happens in mine when I press the home or recent apps while in the call screen, I can drag the top menu but that's about it, in this menu even if I press the little gear to go to settings it opens it in the background and once the call is over that will be the first screen that I can see. But somehow the call screen is always on top. On this phone I can't get the green bar, I'm used to it from all my other past android phones, but not on this one.
Any ideas?

Question Something weird happening on vivid mode

Received my S21U yesterday and noticed a weird thing happens when vivid mode is on.
Basically, the colours change when apps take up the whole screen. It's mostly a slight change but it's really visible on skin tones. On my device when things are full screen, people's faces look pale, yellow and washed out. This disappears immediately if I put the app into pop-up view, splitscreen, or if I open another pop up app over the top. It also disappears if I swipe up to go to recent apps and the current app minimizes. It's annoying because the skin tones look normal and healthy when not full screen. Then as soon I full screen whatever I'm looking at the colours change straight away before my eyes and I see the washed out yellow skin tones appear. This doesn't happen on natural mode or when eye comfort is on, it only happens with vivid.
The same issue happened on my Note 20 Ultra, but the yellowed/washed out colours were SO much worse that I ended up returning it. Oddly enough it doesn't happen on my Tab S7+.
If you have a spare minute and you'd like to see if this happens on your device, open this random image of the legend William Hung full screen with vivid mode on. Then try swiping up to see recent apps and then tapping the app to full screen the image again. If the same thing happens on your device you should notice the skin tones change. He should look normal when the window isn't full but on full screen he looks really yellow and ill. The same should happen if you open it in split screen or popup view or open another app in pop up view over the top.
Anyone else noticed this or know why it happens? It actually kind of annoys me as the skin tones look ugly and at this price point I expect everything to be perfect.
Cheers!
Cheers!
Just checked, and I'm unable to duplicate that problem with the picture you shared. No change it skin tone at all.
NVM, I see what you mean. I see a darker shade in the recent apps menu when I swipe up, and then when I go back to the original image, it gets lighter. NOt a big deal to me. Why does it bother you?
