I scheduled for an auto restart 9 for sundays at 3 am. It has a memo that a restart happened 9 days ago. I manually restarted the device and the memo never changed. I set the schedule for the current day and time by 1 minute and it did not auto restart.
Guess the auto restart no working on s25u nor is the memo being updated if it did.
Aside from the conditions that PianoManJay mentioned, I would add that I have found that if the phone has not been idle for at least a half hour before the scheduled time, it will not auto restart. Also, there seems to be a bit of a grace period based on the idle time, so if you use the phone within a short time alter the set time, it will not restart if the schedule was delayed but will restart within a half hour of the scheduled time if the phone remains idle. It's not always possible to have the phone idle at the scheduled time, so you can always set a secondary time/day to restart. Manual restarts will perform an optimuzation, but will not change the auto restart message, as that will only tell you when the phone automatically restarted.
