hey all. I'm having trouble with my 6s lately. the touch screen just stops working after a while of usage . usually happens after long phone calls or gaming (like PUBG). so when this happens the home button works and the phone responds to other buttons but the touchscreen seems frozen and the upper back seems a little hot (not extreme). what I do in result is turn of the display for a bout 4-5 min and then everything seems fine and goes back to normal. whats going on? is it the cpu? battery? (my battery is at 1400 capacity so its not super..) should I replace the battery? cpu? thanks for the help guys..
