Samsung Galaxy S8 / S8+ - Restart Device

Here's how to restart your Galaxy S8 / S8+ if it crashes or resets, freezes or runs slowly.
  • Since this device has a non-removable battery, restart (soft reset) process can be used to simulate a 'battery pull' when the device is unresponsive, frozen or doesn't power on.
  • In rare cases, a restart could affect data (e.g., backup in progress, cached data, etc.).

Preferred Method

  1. Press and hold the
    Power button
     (right edge).
    If the device is unresponsive, attempt the alternate method.

    Volume Down button
     (left edge) and the
