Question Strange screen flickering when Power saving is on - Samsung Galaxy S22 Ultra

UPDATE:
I managed to record when it's covering the whole screen. Please see that two added videos ("Extreme").
Well I guess it's time to report to Samsung.
-------
Hi,
I managed to capture a strange screen flickering. In this video - just a small bar (and only visible when scrolling).
In all other cases - it covers the whole screen and the only way to get rid of it - turn off power saving mode (impossible if all screen is covered with this static) or connect to power supply.
This happens only when the Power saving is ON (in my case - automatically if battery goes below 25%).
Turn Power saving off and it goes away.
Any idea what's that?

If you turn on standard rather than adoptive display at the same time as power saving ?

Well.. it's hard to reproduce because it doesn't happen often. But yes.. I could run a test (standard + power saving).
I updated my OP. Please see the videos when it covers the whole screen.

Backlight off/on when locking/unlocking Blackstone

Hi,
In lock mode backlight stays on albeit on a lower level, but still. This causes problems like:
1. it uses valuable battery power
2. maybe even more important: it is too much light in my bedroom (need a good rest).
Furthermore: the best mobile ever will be gratefull if we don't use the power button for switching backlight on/off, showing this by a longer button live.
The best solution would of course be if when locking/unlocking the phone the backlight would go completely off/on.
I can't find this combination of functions (un)locking + backlight (on)off on the forum. Any genius ideas?
Thanks

[Request App] Another ways to avoid using the power button

I observed that we have only used power button to turn the screen on and off.
Think about it, how many time we have to put this button for one day.
From the screen ON to OFF state, I think we can write a software to turn the system to the standby mode.
But not on the screen OFF to ON state, is there any way to use other button like the track ball to control the screen up.
I think there are several posts on this...

[Q] Phone lag when battery is low

Has anyone else notice that their M8 is noticeably less responsive when the battery gets low (usually under 15%)? I am aware that the Verizon model does not have the extreme power saving mode feature; however, I noticed something funny. When the battery is low and I go into developer options to turn on high performance mode, it lets me know that I cannot due to power saver being on (see screenshot). When the phone's battery is not low, I do not see this message and I can enable high performance mode. My guess is that the phone is entering some sort of power saving mode automatically when the battery gets low because I notice that it lasts quite long on low battery and is less snappy.
Fast start to finish here. But I'm running custom so.

Can anyone else on stock replicate this issue or did I just get a defective M8? Thanks!

It honestly sounds like power saving mode is kicking in. Which does at 15% on stock if power saving mode is enabled ( not extreme power saving mode just the standard one)
If something weird is going on and it is not providing you with a notification that it is what's happening, next time it happens look at /sys/devices/system/cpu/cpu0/scaling_max_freq if it's at 2265600 then it's not in power saving mode, however if it's at 1190400 then power saver is on. Other signs of power saving mode would "normally" be
Display brightness reduced
Cpu reduced speeds
Vibration feedback turned off
*data connection put to sleep when screen off
Edit:
Turned my power saving mode on and I also can not turn on high performance mode. So I bet that is EXACTLY what's going on.
last edit,
if you have root you can launch the power saving settings ( even tho the option is not there under the power sub menu vzw left all the code in)
to do this from terminal emulator at # am start -a android.intent.action.MAIN -n com.htc.htcpowermanager/com.htc.htcpowermanager.powersaver.PowerSaverActivity
this will launch the settings for power saving mode, and from here you can see if it is set to on, if so just turn it back off.

Thanks for the reply, I agree with you on that one, I'm pretty sure power saving mode is being turned on somehow. I'm not rooted and on stock, so I don't have a toggle for power saver mode. Any idea how it could have turned itself on? Aside from rooting, is there anything short of a factory reset that I can do to get rid of it?

Well I would first ask if any of the things I said happen when you phone goes below 15% such as
Display brightness reduced
Cpu reduced speeds
Vibration feedback turned off
*data connection put to sleep when screen off
Some of these you can check without root. Like the screen gets dim or the vibration turns off. If so then let me know.
Theoretically a factory reset would clear it. However you could try to clear data from the settings app.

+1 on Power Save coming on.....I am on Viper so I see it is turned on at 15% with the quick settings, so I tap it to turn it off (which I know there isn't a stock equivalent)....but when it is on...the phone slows like a turd.

Hyperlapse Camera Mode Use With Screen Off?

Is there a way to use the Hyperlapse camera mode with the screen off? When I tried to do this, the screen never times out (because video is being recorded). Also, when I try to shut off the screen using the power button, the camera stops and the Hyperlapse session ends. The screen is a significant battery user. For this mode, it would be nice to be able to let the screen shut off to conserve battery.
Thanks

The S7 has a feature that senses the subject in front of the lens. Let's start with checking your settings.
From your home screen, tap Apps > Settings > Device.
Tap Display > Smart Stay.
With Smart Stay, the display remains on. Try using Hyperlapse with this feature turned off.

Q: Anyone else's screen not wake up/turn on & stay on properly?

Am i the only one whose screen, when it's off, doesn't turn back on properly? It registers both the fingerprint and the power "button" with haptic feedback, and the screen flickers quickly, but doesn't stay on until trying it finally works randomly, or if i use the squeeze gesture to open the camera immediately after pressing the power button. Locked and stocked too.
What is os version are you running?
Does this happen indoors or out?
I used to have an issue where auto brightness would immediately adjust to 0. The screen itself was on but the backlight was essentially turned of.
Only noticed it outside and auto-brightness was on (didn't even think that might be related to the issue! good call. If it happens again, I'll turn that off and see if the issue persists). Running 8.0.0.0 w/ 1.30.617.2 in USA
I have similar experience with my unlocked U12+ and may be Smart screen affected somehow screen back light. I've tried different combinations of settings (automatic Brightness on/off), Smart screen on/off and I noticed lack off problem in dark room. Even though some very strange reactions off haptic buttons (volume down by itself) makes me think about some general functionality problems of this device.
Has anyone noticed whether pressure on a particular point on the display affects the backlight?
When I squeeze moderately strong with two fingers in the area of ​​the padlock (that is seen in a locked screen), it's the same as pressing the power button.
I've been using HTC flags for a long time, but for the first time I've come across such a touch-sensitive device. Every touch wakes him up, even in my pocket, which uses a battery.
I am terrified that there is no separate adjustment of the power and response style of touch-sensitive locations (haptic buttons, squeeze sensor)
