After I install almost any rom, the screen no longer turns off normally. Theres always a little flash before the display shuts off. At first I thought it was linked to the crt animation, however even when I disable crt and disable the animations from the developers settings, the flash always stays. I believe there was a rom that i installed that didnt have this problem, and im pretty sure that one didnt have a crt animation setting. But I can't really find that rom or any rom without crt animation anymore to test with.
Theres a link to a video where I try to show this. Its hard to actually capture since its all very fast, and Im not too good with cameras. But you could still see it.
The first time is turning it on and off with the default rom that came with the phone -- Display turns off normally, no flash before turning off.
The second is with CM10.2 right after installation -- There is a flash before the screen shuts off, but its hard to see with the crt animation.
The third is also with CM10.2 with crt and animations off -- There is still a flash before the screen turns off (seen best in the 2nd to last instance)
The flash mostly comes from the upper right corner area if that helps.
Its hard to see on video because of the changing in lighting from turning the phone on and off, but its very noticable in person.
How can i fix this, or is this a condition on all phones?
Edit: You can see it a lot better in this video after i turned it off and on with a black background
Is there a pre-installed screen recording app that came with our phones? Today in recent apps I had a notification that screen recording is running and also noticed a new notification icon that looks like a camera.
I have no idea how to turn it off (besides rebooting phone) and never saw an option to do this let alone turn it on.
I also noticed I get a small circle on my screen wherever I touch it. Never noticed that before.... Any idea what is going on?
Is anyone else seeing a flicker in their app launcher? Occasionally, when opening the app launcher and scrolling I will get a weird flicker where my background with phase into my app drawer. The only way to fix it is to turn off the display and then turn it back on. Not a big deal, but is kind of annoying. If I can I will try to get a screen capture or recording of it.
I have a s8+ from Verizon and whenever I enable screen rotation, it doesn't rotate, and if it does it takes a long time to change orientation, and it gets stuck in that orientation until I turn screen rotation off. And this is with all apps, it's not that bad on YouTube but all other apps it struggles. Has anyone had this problem?
I have the same issue and all I can suggest is a temporary fix. Install xposed and get forced screen rotation mod. I also added the menu button to my navbar through GravityBox and assigned screen rotation to the long press,for quick access
I did and I fixed it. In the quick settings panel click the icon that says Portrait.
EDIT:
I misread the original post. My solution may not apply to your problem. Mine was not rotating and I couldn't find the setting anywhere! I was looking for the screen rotation icon - not a "portrait" icon.
Has anyone has an issue where the screen won't turn on after using the fingerprint sensor? I can feel it unlock but I sometimes have to hold the power button until the power off/reboot menu comes up which then starts the display up from being all black. Have Magisk beta and Xposed installed so maybe that's the issue?

Is AOD on or off? What happens when it's on?

AOD is on. So what happens is if the phone is on my desk and AOD is showing time, it'll show the notification briefly then just go black(nothing is covering proximity sensor and notification light is blinking). I then usually have to either do the power menu trick I mentioned or just restart the phone. If it's in my pocket on the other hand I'll pull it out and it'll be black with a notification light.
Oddly enough it usually only occurs with Snapchat so I think it may have to do with having snaptools installed?

Quite possibly so. I know nothing about snap face, snap chat, or whatever these social media apps do. Although, you may try clearing the app data and cache on said app to see if it helps. No guarantees though. As is the case with many things android! ??
I've had the same issue ever since I installed, I believe, the nav bar immersive mod. Not sure, around same time. I was able to hurt power button twice for camera and that would pull it up and u could switch back to screen. I don't have xposed or Snapchat, so I don't think either of those are it. It's random when it happens to me.
I've had similar issues. I'm not rooted and have never used Snapchat or AOD. I do use immersive mode for some apps so I've thought that might be causing it. Like stated above, I can get the screen to come on my double tap to open the camera or just holding the phone face down and tap the back a couple times then flip back over and the screen comes on.
I'm also having this issue. Ambient display seems to prevent the issue for me. If I reboot the issue is gone for a period as well. Not rooted but have immersive mode acrive via nav bar hider.

Ok so a little more testing. When Ambient display is set to always on, I have no issue, maybe a slight lag when waking/unlocking. When ambient is set to tap or pick up i get issues, when ambient display is set to off at all times, i have no issue. Plugging the phone in to charge seems to force the issue to happen.
Edit: Seems that even with ambient display off totally the issue pops up. Strange thing is if i unlock the phone and take a screen shot, its totally black.
I to have this happen and like sportytony I use camera to wake device. Sometimes that too takes a bit. Most of the time when it finally does wake there will be a notification that systemui isn't responding. So I wonder if it's related.
Ok, I've been having this issue happen multiple times a day. I use this immersive app: https://play.google.com/store/apps/details?id=in.tsdo.elw
Since I have turned all ambient display options off and made sure that System UI is unchecked in the immersive app i haven't had an issue at all.
Its definitely related to system UI, com.android.systemui to be precise
i used to try to set up Power Nap on this device, but it can't find System UI in app list, make me unable to whitelist it, thus causing same issue like yours,
Screen wont turn on after sleep, since System UI wake up is blocked
I was using hide navbars and had this issue
I uninstalled and never had that problem again

Didn't expect all these replies but I'm going to try to untick system UI and see what happens. Thank you all!
