iPhone 6 home button won't wake up screen
I have had the iPhone 6 since it was first released and lately I've been having more issues with it. Twice in the last week, when I go to check the time or what not, I push the home screen and it wont light up. I then try the on/off button and nothing happens. It's like it's turned off. It takes about 2-5 minutes for it to finally work again. I've also noticed little glitches in the screen as well where it flashes so fast you almost don't notice it. How do I fix this?!
iPhone 6, iOS 8.4
