Several times a day I find out that my Sony Ericsson Xperia X10 is waiting for PIN entry, probably because of a soft reboot. It annoys me to no end, and I end up missing calls beacuse of this. Is there a tool or another way to help me find out what actually happened, when, and what caused that?
I read similar reports lately, related to Titanium Backup.. When it runs, it kills apps to back them up, causing the phone process to restart. If you aren't running something similar, I would recommend using USB debugging and the SDK to capture log data.. Known as "logcat" in the Android world.
Is it feasible to disable the SIM pin requirement to avoid the problem in the meantime? Could replace it with the Android pattern lock to retain some security.
