I found this site looking for help with my new Samsung S6 edge SMG925A. The fingerprint scan stopped and back up password phone sayimg wrong password. I've had the phone over 2 months and never had a problem until it just stopped working and I couldn't open my private setting. I searched for information and found nothing to help. Hard reset loss of data, no.that dog won't hunt. So I consider it a challenge. Back later and BTW, I FOUND A WAY AROUND SAMSUNG FINGERPRINT SCAN AND BACKUP PASSWORD. Took me a couple of days, but I got it done and it's not difficult I think anyone can do it. You need nothing but your phone and about 30 seconds.
