Describe the bug

After the display is off with --turn-screen-off or with MOD+o
I can't turn on the screen with MOD+Shift+o.

If i try to turn on the device with double pressing MOD+p (one time for lock the device, and the second for turn on) the display turn on for some milliseconds and turn off again.

The only way to turn on the screen is pressing the MOD+Shift+o even is doesn't work, and now press two times MOD+p

If i don't set --stay-awake and the screen is off, when the timeout screen timer is near to ended (exaclty 5 second before) the screen turn on to make a slight dimming.
For better explaining: Screen timeout is setted to 30secs, at 25secs the screen make a slight dimming. If the screen is off with --turn-screen-off, that slight dimming trigger the screen to turn on

Yes, on some old devices turning the screen on does not work properly (scrcpy just requests to turn off/on, how the device handles it depends on the device/rom). It used to be even worse that what you observe (see 8c8649c dcde578).

If i try to turn on the device with double pressing MOD+p (one time for lock the device, and the second for turn on) the display turn on for some milliseconds and turn off again.

If power on is done via scrcpy, it automatically turns back the screen off: #1577

Sorry, it is device specific, there is probably nothing scrcpy can do.

Ok, thanks for the response.

For my purpose I've found a """"""workaround""""" to turn on the screen remotely, with sending an intent to Tasker from ADB that triggers an action that it double presses the power button, swipes up to show the pin input, inserts the pin (not a safe handling of course) and automatically unlocks the device. Better than nothing...

Anyway, I close this issue accepting your response, thanks again.
