Most phones restart with a long press of the power button, but the exact steps depend on whether you have Android or iPhone and whether the phone is frozen.

Simple restart (most phones)

  • Press and hold the power (or side) button for a few seconds until a menu appears.
  • Tap Restart or Reboot if you see it.
  • If you only see Power off , tap that, wait 10–20 seconds, then hold the power button again to turn it back on.

If the phone is frozen

  • Hold the power button down for 10–20 seconds until the screen goes black and the device restarts (this is a force restart on many Android phones).
  • On some models, you may need to hold power + volume down together for about 10–20 seconds instead.

Samsung Galaxy example

  • Press and hold Volume down + Side (Power) button together until power options show.
  • Tap Restart , then Restart again to confirm.

If the power button is broken or missing

  • Many Android phones let you restart from Settings → System / General management → Power / Restart (wording varies by brand).
  • Some models can reboot from special menus opened with button combinations while plugged into USB or a charger, but the steps vary by brand, so checking your specific model’s support page is safest.

Quick safety tip

  • A restart does not erase your data; a reset / factory reset does, so only choose options labeled reset/factory reset if you truly want to wipe the phone.
