Samsung Galaxy Watch4 / Galaxy Watch4 Classic - Restart Device

Here's how to restart your Galaxy Watch4 / Galaxy Watch4 Classic if it crashes and resets, freezes or runs slowly.
A restart (soft reset) can resolve issues like continuous resetting, rebooting, device crashing, freezing, won't ring or vibrate, can't make or receive calls, device locks up and screen doesn't respond.
  • From your Android™ smartphone, ensure your watch's software is up to date as the steps below apply to the most recent version.
  • A restart / soft reset (turning the device off then back on) is similar to restarting a desktop computer and is one of the first steps in troubleshooting a device.
  • In rare cases, a restart could affect data (e.g., backup in progress, cached data, etc.).
  • This watch has a non-removable battery. This process can be used to simulate a 'battery pull' when the watch is unresponsive, frozen or doesn't power on.

Preferred Method

  1. From the watch screen, press and hold the
    Power / Home button
    and
    Back button
    until the 'Power off' prompt appears (approximately 3 seconds) then release.

    Allow up to 30 seconds for the reset to complete.

    Power / Home button
    and
    Back button
