Why is my iPhone 6 screen shacking and touch screen doesn't work?
Recently, I recieved iPhone 6 that has broken screen from my friend.
It works normally and fuctioning ok when I restart the phone. But like 10 minutes later, the screen is shaking and touch screen seems doesn’t work.
At first, I assumed that the touch ic chip was broken. But in my case, there is no grey bar on the top of the screen.
What is the problem with my phone?
Broken ic chip or just screen problem?
