I have a fold, I can unlock my phone with my pic and any fingers that was not registered. I can't believe this is still happening. So disappointed. I had been with Apple for 6+ yrs. Apple never had this kind of issues. I have tried galaxy 7,8,9 and notes in last 6 yrs and returned them all because those are slow, laggy, not secure..... I admit that galaxy is improved in every way and finally I found the phone I might keep. I just hope that galaxy gets more secured and improved with better software for like adaptive brightness(so I don't have to change brightness constantly).
