You give me too much credit, my friend. I haven't tested it in Safe Mode because the problem is so intermittent. I'd have to go for days - maybe longer - without any of my "must have" apps. And if I run into the problem, and then boot into Safe Mode, it doesn't solve anything because rebooting would have fixed it anyways. I could start to journal and see what apps I used before it started acting up, but I'm not even sure app has to be started by me - it could be doing a background check or something.
I do know that I must do a real reboot - using a program like
Fast Reboot which doesn't really reboot your phone, only the apps and processes, does not fix it.
