For my play at home this morning, I had intended to try a new tactic: open FOM before OPO, let my phone sleep, go to my lock screen where I can see the seconds tick down, then unlock right at 8 to see if the FOM screen refreshes with unlock.
Unfortunately, I got my finger on the sensor too soon and unlocked a few seconds before OPO. So I went into MS and got no joy. Had to close the app. Seems like a bad approach since if I get jittery at all it could lead to a restart situation, but I might try it again tomorrow for fun.
