Iphone won't turn on
My Iphone XR won't turn back on. I've had it less than one year and it was stuck on the Apple Logo screen for days. I tried the trick with the volume button up and down then hard reset and resetting it through Itunes but nothing seems to work. It died so I tried charging it and it stays on the charging logo for a long time, then every once in a while it will change back to the apple logo and then die again while it's on a charger and just remain on the charging logo on the black screen.
iPhone XR, iOS 12
