I have tried every option, but my phone will not lock. My new Galaxy 6 is great BUT I have to have my phone locked. I work at a bank and it is required for people who have email on their personal phone. I have tried the following to lock my phone, but it always defaults back to swipe to unlock:
All default back to swipe. The New Theme Pattern worked the longest (two or three times) in a row, but defaulted back.
I have tried resetting all time outs and any other options the internet has told me to try but with no luck.
I have NOT tried SAFE mode, because I do not know how to do that.
