My iPhone Keeps Rebooting Randomly, Fix

Many users have experienced a problem where their iPhone randomly restarts. Does your iPhone reboot itself? Does your device display the Apple logo out of nowhere and you have no idea what is going on? In this article, we will explain some of the reasons your iPhone may be restarting itself. We will also give you some tips on what you can do to fix the problem.

Here are three versions of the problem:

  • You are using your iPhone without any problems, maybe you are playing a game or something, but then suddenly your iPhone restarts.
  • You cannot use your iPhone because your iPhone keeps rebooting itself over and over. This means that your iPhone may get stuck during start-up.
  • Your iPhone reboots itself and you only see the Apple logo or a white, red, black, or blue screen.

4. Remove the SIM Card

Sometimes a SIM card can cause a problem with your phone. You can remove the SIM card, then see if the rebooting problem persists. You can always put the SIM card back in. If your iPhone seems fine when there is no SIM card, but has problems when the SIM card is in place, you may want to contact your cell carrier.

  • Use a paperclip to open the SIM tray. Push in, but don’t force it.
  • Your SIM tray may be on either the left or right side of your iPhone, depending on the model.
