A while back I dropped my N7 and it stopped working. Eventually I ended up popping the back off, and reattaching the battery connection. All seemed well after that. This weekend I was out and about for the day and took the N7 with me in my purse. I carried my bag normally; I didn't swing it or drop it or use it to beat off attackers or anything "stressful". However, at some point I went to use the Nexus and it didn't turn on. Again, I had to reattach the battery. Is this normal? It seems extremely sensitive if I can't carry it in my bag. And, yes, it is in a protective cover, although I don't think that matters; I think its the movement that shakes the connector loose. At any rate, I'm not happy about this.
