Heating issue after 2009.47 update
It's Google Play Store which is creating heat. When u download/update app from play store.
Just check the armoury crate, it misbehaves temperature goes high.
Temporary solution is that just clear the cache of play store, armoury crate, and Google Play services and then restart your phone.
Here is my screenshot attached after doing it.
Note: Everytime i have to do
while i download/update app from play store.
