Phone finally crapped out today. I had been getting locked out for about a month; this would happen a) when I didn't have a data connection (lost it for about a week when I was in a remote area. ugh), b) if battery went below 50 or c) if it was in the middle of an upgrade/download/upload whatever the hell it does behind the scenes. Today, even with fully charged, 4G optimum conditions I was seriously locked out. So having a contract, I took it back to best buy and got a loaner. But I could not get in to return to original settings and wipe it clean. I took the SIM card. Is that sufficient or do I need to do something somehow from here. Call someone? I tooled around Google hoping to disable access in some way, but I couldn't find anything. So I'm hoping one of you can tell me if sensitive information/passwords might be compromised. Assume rightly that I've been doing everything I can on my phone. I wonder how much of it remains on my gnex, and whether it can be accessed by someone else.
