I have been experiencing issues with my fingerprint setup after upgrading my Samsung a70 to Android 10 this morning.
The issue is attached in the screenshot.
I think it has something to do with the upgrade.
Same here since update on 9 April.
I get same message as you.
I deleted my fingerprint data but constantly get the 'fingerprint sensor calibration needed' message.
I have just tried 'wipe cache partition' but no difference.
I was told by Samsung that I'd have to send my phone to them.
I guess they'll factory reset it?
Why can't they just fix this problem "over air"?
Hi guys and gals,
Im new here but i think i can help.
I have an A70 and just updated to Android 10. At fiest my fingerpring scanner was all good but then just stopped recognizing my fingerprint. I tried to redo it but nothing worked. So i tried an old fix.
Go to your dialler and enter *#2663#
You will see the below screen, ONLY hit TSP FW update. It will update. Once done retry your fingerprint. It worked immediately for me. No errors.
