A50s Android 10 update issues

[Sefat890]

After updating Android 9 to Android 10, my phone isn’t working well as before.   Fingerprint isn’t working.    It shows fingerprint calibration needed.

Also battery drain so fast. Camera quality is not good as before. I want to help someone to fix this problem. Or how to downgrade  android 10 to android 9??

Take backup and Reset ur phone from recovery menu. Press And hold Volume+ and power button and hold Vol+ till u see recovery menu and then select Delete user data.

That doesn't work. I think it's a Operating system problem.
