Why is that my SG E7's back temperature is gradually increasing?

[JohnYx Sorilla]

I've just had my SG E7 last month and I was really amaze of it, but one thing that I've been noticing that even if I am not using the phone the temperature of SG E7 is increasing, I've tried to kill all the apps that I thought the cause of it but still the same.

Do you have an SD card inserted? A corrupt file (usually a media file, like a photo, video, or music file) on the SD card can cause the system's Media Scanner to get stuck, which can contribute to excessive CPU use, battery drain, and heating. Try unmounting the card (in Settings>Storage), removing the card, and rebooting. Insert the card into your computer's SD reader and run chkdsk to look for bad sectors: http://forums.androidcentral.com/am...guide-using-chkdsk-fix-corrupted-sd-card.html
