I have a J5 and every day the auto restart feature did it's job at 3.00am with no problems. I installed the latest update yesterday and was woken just after 3.00am by a clicking sound from my phone. The phone had restarted, but is now requiring my unlock pattern to complete the restart. Anyone else having this problem and what can I do to stop it needing the pattern on auto restart. FYI, my Samsung tablet restarts daily without needing the pattern.
