Switch off screen not working

[srevinsaju]

For my guiscrcPy project, I tried to use switch off screen option, and I get the info on terminal that is screen is switched off, but unfortunately, the screen instead of being switched off, it is rather freezing. That I can put the flag or use the shortcut, but at that moment it freezes the screen on the mobile, but screen mirroring works fine.

What if you just pass -S to scrcpy (without guiscrcPy)? It is the same behavior?

[srevinsaju]

Yea, I did. I even used the shortcut manually. The screen freezes. but mobile display doesn't turn off. I even get the log message, device screen turned off. After device power on and off, everything resets.

Weird, your device seems to react to setPowerMode() oddly. What device is it?

When you turn screen off, what does adb logcat says?

[srevinsaju]

The mobile is GT-N7100 (Samsung Galaxy Note 2) running a nougat custom ROM AICP. The logcat is attached below. I found scrcpy giving instructions.
log.txt

SurfaceFlinger: Set power mode=0, type=0 flinger=0x40832000

Seems correct.

The problem should probably be reported on AICP. They might have more information about the issue.

I will check this with another ROM and close this issue if it works. thanks for your time.

I'm having the exact same issue with a Pixel 3 XL Running Android Q (both beta4 and beta5) the screen doesn't turn off and the scrcpy window stops sending input. Phone screen still works fine and I can still see mirroring there's just no input from scrcpy.

Works fine on my Pixel 2 with android9 pie so not sure if it's the device itself or issue caused by Q beta.

I tried on Havoc OS too on Galaxy Note 2, Pie (9.0), but still this option doesn't work

This is a separate issue specific to Android Q beta, which is already fixed on master: #586 #587.

Having same issue, but there is an option in Engineering Mode to turn off LCM which works fine, but turning off LCD doesn't work.

Please test on dev branch (after commit c33a147). See #835
