The phone won't turn on
I just bought an Iphone 6 plus and the phone worked fine for the first few days and then suddenly stopped. I tried changing the battery but still no live from it. Then i left it for a few hours chraging and it openned for a couple of seconds then stopped again.
The phone had a cracked display and I assumed that it may be the problem, then I changed it.
I left it for a few hours again to charge and it got a few minutes of live, stopped again.
I don’t know what to do after this and I am stuck right now.
