Asus Zenfone 5z heating issue
ರವೀಶHeating problem is common in summer and while charging or playing pubg type games on max settings. Selfiemaster app was removed in A10 so it wont be available any more. As of heating while using camera app, try clearing cache and restore default settings for camera and do custom settings again.
