Finger print sensor XA2 not working

Finger print sensor XA2 not working

I recently got the Xperia XA2 and have been using it for around a week and all has been fine. However, the finger print scanner is no longer working. When I go to add a new fingerprint, it immediately comes up with a message saying it is unable to add another one. Has anyone else encountered this problem?

Re: Finger print sensor XA2 not working

So mine just stopped working about 30 minutes ago. I already have 2 prints saved which obviously don't with and can't add a new fingerprint either.

Re: Finger print sensor XA2 not working

I just bought an Xperia Xa2 ultra 6 days ago and the fingerprint scanner worked fine for the first days but hours ago, 90% of the time it either says not recognized or couldn't process fingerprint. Now, it doesnt recognize my fingerprint or any fingerprint at all. I tried to remove my fingerprint set-up, clean my fingerprint sensor and restart the device. But still, it doesnt work. Please help. Thanks

Re: Finger print sensor XA2 not working

I have the exact same issue. A month ago I fixed it with a factory reset but after a few weeks it happened again.

Re: Finger print sensor XA2 not working

Update:

 

For some reason about 2 nights ago, my phone decided to shutdown. I thought my battery had run flat (though I was sure it had about 30% left) but it booted itself back up. Sure enough, I had enough battery on the phone. I hadn't been doing anything on the phone at the time that would cause an automatic reboot so the behaviour was completely unexpected. I thought nothing of it.

 

Shortly after picking up the phone to use, I discovered (accidentally) that the fingerprint sensor started to respond again as it normally would (though I did have to re-save new fingerprints). It fails to log me into my Banking app (thought that may be to do with the app itself) but logging in to the PayPal app works just fine.

 

I don't know what has changed to cause the sensor to start reading fingerprints now or how long it will last before it stops responding, but it definitely did start working again on its own. Hit me up on twitter if you have any other questions.
