I bought Xperia Z C6602 on 11/Sep/2013. Since that day, I have been noticing that my device becomes hot while doing some normal activity like talking some or listening music only for 10-15 minutes. I went through Sony Forums and found this issue is known by Sony. But I am not able to find any proper solution for this issue. I am aware of heating issue while charging your device or playing games for long time but what about Calling or Music. One support person on forum, was saying that overheating is common on quad-core process chipped devices. But I don't see same issue on Samsung Note 2 or HTC One X or HTC One. Why I am scared because it becomes so hot while talking to someone even you can't hold it. And heat or temperature is only coming out from Upper Body of device(both sides on device). Is there anybody else having same issue ? Here is link to my post in Sony's Forum -http://talk.sonymobile.com/t5/Xperia-Z-ZL-ZR/Overheating-problem/m-p/375219/highlight/true#M17881 Please give your suggestion or comment here if you need more details about issue or device.
I own Xperia ZL and I do face the same issue. I got the same answer also. Let's just hope Sony has a proper answer for this issue.
