Fairphone 4 laggy, reboots

/e/OS Devices Fairphone

Hello, fellow users!

I have a new problem with my Fairphon 4 on e/OS/2.8. It has become very laggy and unresponsive at times. Sometimes it even restarts itself without me knowing that it happens (in standby).

When it is laggy, it can happen that I tap and there is no reaction for a couple of seconds (One Mississippy, two Mississippy, three…). Then the used app starts working again and after that I get the “kill window”, where I can choose to wait or to kill the app. In this moment, the app is functional again, so I go to “wait” but the window reappears after a couple of seconds again, so I have to kill the app, to get rid of it.

The battery is a new one, only 2 weeks old, so that should not be the reason for the restarts.

Thank you for the advice!

Cheers,
Dejan

EDIT:
While one app might be laggy and stopping to work, switching to another app is possible.

The Camera might hang often, too.

There is a thread about Fairphone 5 with similar issues. I will try starting the Camera first, as the user suggests. Fairphone 5 lags if camera not opened first

After some time, I can tell, that starting the Camera right at the system restart, is helping a big deal. So: Fairphone 4 and 5 seem to have the same problem with e/OS 2.8.

I have let “SD Maid SE” clean up a bit. Perhaps this will help, too.
