We just got an S7 on Friday. I set the phone up and it transferred information over from an old S4. The password to unlock the phone quit working and I thought it was something that I had done. The last app installed was MobileIron@work. SO thinking it was a glitch with that app I did a factory reset and loaded everything back on minus MobileIron. We are on the 2nd day using the phone and now the password again says it's incorrect. We were using the phone 5 hours ago and now the password is rejecting. Has anyone heard of an issue with this. I have tried Google Device Manager and it connects to the phone but won't let me change the lock password. Any advice before I factory reset again?
