Hello: My friend and I are Samsung phone users. Mine is a Galaxy 6 with which I have had no problems. My friend's phone is a Galaxy Note 5. Both phones are less than 6 months old. As of today, my friend's phone has locked him out for no apparent reason. Some apps were updated, he is unsure which ones, and he was requested to restart his phone. Then he was unable to access his phone. He uses a fingerprint security system and apparently no back-up number PIN. The phone will not accept his fingerprint. Neither one of us have a Samsung account (mine will be taken care of as of today!) so Samsung cannot help us although they have tried. My friend does not want to go the route of a factory re-set, as he does not want to lose any contact information or photographs. Does anyone out there have any ideas as to how he can get into his phone? Much thanks.
