fingerprint sensor doesn't work

@eliastamene first check your phone's settings to see if the fingerprint sensor still shows. If your sensor does no longer show in settings, then you will have to consider replacing the fingerprint reader. Make sure that your software is up to date. Samsung sure seems to have plenty of issues with their fingerprint sensor.

I suggest that the very first thing to do, is to check on Samsungs site for their suggested fixes. If none of this works, you do want to go ahead and replace the fingerprint reader.

To replace it, use something like this video Replacement fingerprint sensors/flex are widely available at plenty of online stores. Just make sure that you purchase one for your particular version of the A10s

While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do.
