I have purchased Xperia z5 dual on 22ND of June 2016....it's been only one day of use but the device is heating excessively, let me also inform you that when I switched on the device it took me to updates and I have now android 6.0.1 but the device is heating excessively no matter what ever work I am doing on it, please let me know why is it happening and what is the solution.
