Just updated my S5e toOne UI 2.5 and looks like majority of lagging/stuttering problems have been resolved. Also WiFi lost connectivity on startup has also been sorted out. Early days though so will need to monitor performance.
Same issue for me with my Samsung S5e since updating to Android 10. I have tried the cache clearing, completely reset but its still the same. Very frustrating - please fix this Samsung!
Anyway of going back to Android 9?
Returned my S5e to factory settings and then resolved not to install ANY apps from Play Store marked as "this device may not be optimised for this application". So far so good as there hasn't been any lag or stuttering and everything is working as it should. If that has been the problem all along then unfortunately it highlights the lack of support for Android tablets from some app developers. A pity.
I have the same issues since upgrading to Android 10. Very frustrating and makes the tablet useless.
I tried doing a factory reset, but it started with Android 10. A tablet is a bit useless if you can't install any apps!
Does anyone know if you can install Android 9 and ignore the Android 10 upgrade?
