So today I dropped my iPhone 4, and I couldn't turn it on after so I plugged it in as if it were charging and it turned on and everything appeared as if it were all right but when I unplugged it it turned back off, and the only time it can be on is when it is plugged in. I also noticed that when it is charging / plugged in it stays at 19 percent but appears as if it is charging but it really isnt going anywhere. Can anyone help me with what to do? Thanks
