I have a samsung A22 which is not supported by any of the foss roms i would like to try, so i started to debloat my phone and logout from google, removing as much propietary software as i can from my phone and replacing by foss alternatives. The only thintg i didnt manage to do is removing google services as i live in a country where foss options of maps apps doesnt work very well unfortunately so I have to stick with google maps. I tried Gmaps WV but it still needs google play services to work. I also added the micro G repository but I cant see the option to install it, is it possible?
Look for a GSI ROM. They generally work on any device that came out with Android 10 or newer.
In my case, someone did the work of overcoming Knox with their own ROM, etc. Right now my galaxy tab 2019 has LineageOS 20 and a microg setup through magisk. It supplies the spoof fix systemlessly. You might be able to use the same ROM, which is a GSI by Andy Yan.
I would but Im still not that tech savy so im afraid to brick my device
