I've had the Xperia M2 for only 2 weeks and I noticed 2 days ago that the upper half of the phone was becoming thicker than the bottom half, like it was somehow expanding, maybe I'm just paranoid but I swear I feel it. I'm guessing that it is a problem with the battery but I can't see how that is possible seeing has I have only had it for 2 weeks. Has anyone else had this problem?
