Vertical flickering lines and unresponsive screen on my IPhone 6 Plus.
My iPhone 6 Plus keeps on having weird flickering grey/white vertical lines that drag down from the top of the screen on a regular basis, it only stops when I hit it in the back really hard and sometimes my iPhone screen is unresponsive, I wouldn't be able to click on any apps that I want to and sometimes the Phone would open up another app.
Another thing is that when I pressed on the top of my iPhone screen , I see these white lines that look like there's water in it which I suspect it does. My AppleCare expired recently and I'm nervous to go into a telephone shop to get it fixed because I have no knowledge on how much it will cost.
Please help me.
iPhone 6 Plus, iOS 9.2.1
