Install fresh over the existing installation

Hi all!

I have the problem that my phone hangs a couple times every day. Initially the apps are blamed but after a while the apps System-UI and system gibe themselves away.

Is there a way to analyze the problem OTA? Is there a pro to whom I can bring the phone to analyze the problem? I have seen others reporting it, too. Fairphone 5 lags if camera not opened first

I have some valuable data on the phone, so I am avoiding a reset to factory settings. I am not sure that this would help. Is it possible to somehow overwrite the installation and rebuild?

Sorry, just a normal user, so please excuse any errors in my thoughts.

Not without deleting all the data on the device, which is exactly now what you want as you wrote.

Every update overwrites system.

However the development of /e/ does seem to cause frequent unhelpful material in cache.

When you identify problems like

it it often helpful to Clear cache for each identified. Often another clue is apps (maybe system apps) which seem unusually high in battery usage figures.

Settings > Apps > show all > top right 3 dot menu > Show system > Search …

(system will show as Lineage system or so.)

Will try that.

I have deleted my contact widgets that are added through System-UI. It seems that my problem is mitigated by that. I will report back if it comes back. I will try deleting the caches then for Lineage System and System-UI.
