Screen/display gets switched on by itself / Phone wakes up from suspend

[Anna]

Since a while my phone does not remain in standby: For some reason (without any messages coming in etc.) the screen switches itself on and either the lockscreen (with time, date, connections) is visible or the screen is black, but on (i.e. not switched off but displaying a black surface, as you can tell by the glow).

This of course drains huge amounts of energy and reduces the standby time from two days to a few hours.

Other than the power settings (Screen blank after two minutes, automatic suspend on) I have no idea where to look in order to fix it.

Ideas anyone?

I noticed this within PMOS(edge) but only when having a Waydroid session activated.

I don't know what Waydroid is, but on my phone it also happens when no applications are open at all.

On the advice of knowledgeable people I removed the SD card.

Now the phone sleeps like a baby again. Problem solved, sort of.

If you cannot do without an SD card, downgrading to kernel version 5.13 or 5.10 seems to help.

Basically an Android emulator for Linux distributions that are using Wayland rather than X11.
In the case of the PinePhone, Phosh and Plasma Mobile are using them as the only option, Lomiri uses Mir, and SXMO uses X11 (Wayland version is SWMO).
Any of the desktop ones can be either X11 or Wayland.
