SAMSUNG A70 FINGERPRINT NOT WORKING AFTER ANDROID 10 UPDATE

Because I never have much on my actual phone but stored on my micro sd memory card, I usually just wipe the whole device if anything major shows up.
But I understand not everyone wants to or can afford to lose information

I just did this and it worked. 

 

Now my fingerprint is functioning properly.

Thank you

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.

Really annoying!

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"?

Doesn't work.

I haven't tried a factory reset yet.

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.
