So, I had my second lockup on my 920. The first time was clearly a Bluetooth issue. But this time was a bit different. I left my phone downstairs on new years eve and didn't put it on the charger like I normally do. When I went to check my phone the next day it was dead. At first I thought it was not charged. So I set it on my charger. 3 hours later, it still would not come back up. So I plugged it in to a charger. And hour later it wouldn't come back. So I did a reset on it, and voil? it came back to life fully charged. However when I checked my start screen, two of my aps were not there. BBC and Weave aps were missing. I had to re-pin them. So I'm wondering if one of those aps caused the problem
