A50 Fingerprint issue after Android 10 Update

[shesimo28]

Seeking for help:

After updating my A50 for Android 10, the most noticeable issue is the fingerprint.

I cannot unlock my phone with the current fingerprints saved.

I also tried removing a saved fingerprint then try to register a new one. But upon registering the new one, I was stucked with 0% as if my fingerprint is not being read. My fingerprint is being recognized once my fingerprint is there at the sensor and it turns to green color (as it was being read) but there was no progress in registering it. Still stuck at 0%.

Take note: I am using screen protector prior to Android 10 update and it works fine.

Other issues: 

Battery Drains easily

Longer charging time

Netflix App crashes

main reason for all to fail is bug instability you can either wait for next stable update or follow some advice and tips I could give you
1 use adaptive battery
2 use medium power save
3 prevent background apps from consuming data in battery device care
4 put unused apps to sleep
5 reduce some permissions given to apps that are not necessary for running of app
6 use dark mode
7 use location when necessary as in maps Google search or any location based app else constant use loads battery causing heating
8 prevent network inputs like NFC bluetooth WiFi from working together too many network inputs will cause heating and lagging
9 while charging keep phone idle
10 turn off auto sync use when necessary
11 reset phone settings once clear cache
12 if nothing works once try factory reset
13 charge in cool conditions as outside weather will be hot these days
14 dont use vibration if not necessary
15 use accubattery for complete battery diagnostics
I hope this helps because one ui bugs can be fixed by samsung when new updates come till then try these tips they could help to reduce battery heat up and loading so that smooth charging works and device runs smoothly

My phone is currently doing almost all, even prior to update.  

Will try doing number 11, and my last option will be #12.

Thanks.

not yet, as i'm afraid that my files will be deleted if i do so. :(

use backup on sd card or Google drive or OneDrive

[hedgehog · Accepted solution]

reset ur biometric data and re register fresh id
clear app cache of Netflix and reinstall it

For Netflix problem, this was the solution.
But to fingerprint, I don't think so. As i cannot register a new one.

then backup data and factory reset
