iPhone won't turn on
I have an iPhone 6 space grey with a cracked screen. When I tried to turn it on, it showed nothing on the screen. I put it on charge and it showed the battery icon and then a few minutes later the apple logo for a split second, then to a blank screen.
I could see the screen was actually on due to the cracks showing the light through, but after a few minutes there was still nothing.
Is it a battery issue, or is it something else?
