iPhone not turning on
Hi,
My iPhone has been stuck on the “turning on” screen with the white apple logo against a black screen for about two weeks now- I’ve tried pressing the “volume up button” quickly followed by the “volume down button” followed by holding down the “on button” until the charging screen is displayed, and I’ve also tried plugging it into my computer, but nothing has worked and it still hasn’t turned on. Any advice?
iPhone XR, iOS 14
