Added (1). And Brian, i will test that.

Added (2). Did not work T_T

Mine had the same problem I just turned it off and back on.

Check the router is still connected to the Internet. If it is try switching it off the wall as let it restart. And do the same for your iPhone, turn it off and back on. This resets a lot of settings that help the iPhone connect. If this doesn't work contact apple

  • My iPhone turned off by itself and turned back on while using a app? When I was on YouTube my phone just shutted off by itself then turned on. Is there something wrong with the phone. Also when I click my home button one time the phone sometimes wouldnt come on till the second click. What can I do?
  • My iphone 5s will not turn on. Hard reset doesn't work and itunes doesn't recognise it My phone hasn't turned on in 5 days. Doesn't respond to the charger or being plugged into the computer. I've tried the hard reset a thousand times and nothing happens. ITunes won't recognize my phone so I can't do a factory reset. Can anyone tell me another way of resetting my phone?

  • Iphone 6 black screen, home button doesn't work and it won't charge or connect to itunes? Nothing happened to the phone beforehand, I plugged it in to charge and a few minutes later I go to check on my phone and the screen is black and the sleep/wake up button won't turn it on. I try to hold the sleep/wake up button to see if its dead but the red battery doesn't show up. So its not dead but the screen is just black. ON top of that the home button hasn't been working. Any solutions to help me fix it?
