I recently got a new Lumia 830 for Father's Day since my 1020 was stolen earlier in the month. Anyways the phone is great and I have no issues with it as far as performance. My only problem is, the back cover. I can't afford a great case for it yet so it's naked for the time being. I have noticed this past week that the back cover tends to want to come off. What I mean is that it will start to come off a bit, as in 1 or 2 places but it doesn't come off completely. At first I didn't think much of it, but it's been happening all too often. I went to an AT&T store earlier today to see if anything could be done because it was still under the 14 day return/exchange policy. The only thing they can do is take the whole phone in for a complete exchange. That would cost me time backing up, and then restoring a new phone again. I really don't want to go that route. Has anyone had that issue with their 830 and had anything resolved from it. I'm tempted to go to the Microsoft Store to see if they can just warranty a replacement back cover. I have the green cover still new in the box but doesn't look right on the phone. If all else, I will use it.
