  • Lock button on my iPhone won't work? I had just sent a text to my friend and I went to lock my phone but it wouldn't lock. I clicked it again and it gave me the option of turning it off. I turned it off but when I tried to turn it back on it wouldn't so I plugged it in to the computer and it turned on. My phone locks on its own for some reason. Is my lock button stuck or is it the whole phone? Any suggestions before I have to go to my mom about this?
  • My lock button does not work and my iphone 4 won't turn on My lock button does not work. And my iPhone randomly turned off. I tried pressing the lock button as hard as I can, but it still won't turn on. Before my phone turned off it was 73% . I tried plugging it into my laptop and I had no success. Are there any ways for it to turn on? Please and thank you. I also don't have time to go to the apple store.
