Phone screen turns on after starting flight mode

Sensor66

Since about 3 months there is a peculiar behaviour: every time I turn on flight mode, 5 minutes later the screen turns on.
This time of 5 minutes is absolutely stable. Then if I manually turn off the screen, the situation is back to normal.
Of course this leads to problems when I have the phone in my pocket: several times it started clicking buttons that lead to loss of data.
Is there a log where I can see what happens? Thanks!

Sensor66 what loss of data are we talking about here? Any access to data should be prevented when using lockscreen.

I tried and couldn't reproduce it. Can you give exact steps how to do so?

But even if it's reproducible, it may not be due to a change in GrapheneOS.

DeletedUser495 Ehh, when the screen is on, any button can be pushed in my pocket. In my case, I lost data from map software that was recording a trip, and data from calendar items that were erased.
But the point is: the screen should not turn on, unless I press the "screen on" button. What happens is that the screen turns on 5 minutes after I set flight mode (and then of course I turn off the screen).

Sensor66 if you have any persistent notifications active that are regularly updating and wake screen for notifications on this could easily be the case. But reasons may be many. And you should consider using your device with your personal data on in a way that doesn't break your security.

DeletedUser495 The issue is not notifications. When after 5min the screen lights up, there is no notification at all. Just the screen turning on.

What do you mean with this? I am just using the device as normal, only since 3 months there is this behavior after activating flight mode.

The problem is still there. Nearly every time when I turn on Flight mode (usually once a day before going to sleep, but it may happen at other times during the day), after 5 minutes the screen turns on.

My question now: can I inspect a log file that tells me what is happening on the phone?
