Why is my phone over heating? only using one app!
started happing after i used a cheap portable charger.
The Samsung Galaxy S4, model i9505, features a 13-megapixel rear camera, and a 5-inch 1080p display.
Your battery and some of the components of your motherboard is damaged .
reason is the CHEAP CHARGER . cheap chargers make Voltage Swims in m.b components .
please replace your battery and try to use fabric samsung charger .
if it didn't work it means that your m.b is damaged and u must replace it :(
