How to Turn On a Samsung Galaxy Watch—and What to Do if the Screen Stays Black

To turn on a Samsung Galaxy Watch, press and hold its Home/Power button until the display lights up. If the screen stays black, charge the watch for a few minutes and try again. If it appears frozen or unresponsive, use the two-button forced-restart procedure below instead.

Turn on the watch with its Home/Power button

  1. Find the watch’s Home/Power button. Button placement can vary by model, so check the guide for your exact watch if you are unsure which button it is.
  2. Press and hold Home/Power until the display lights up, then release it. Samsung’s Gear S3 user guide gives this instruction for that model; it does not establish a universal hold duration for every Galaxy Watch.

Turning on the watch is separate from setting it up. For Canadian-market devices, Samsung says Galaxy Watch4 and later Wear OS models need a compatible phone for initial setup. Some earlier models—the Galaxy Watch, Galaxy Watch Active, Active2, and Watch3—can be set up without a phone. Samsung notes that screens and settings can vary by country.

My Samsung watch won’t turn on: check the battery first

A fully depleted battery can leave the display black. Place the watch on a compatible charger, make sure the charger is connected and aligned correctly, and leave the watch charging for a few minutes before trying the Home/Power button again. Samsung’s charging guide covers model-dependent charging practices.

Use the charger supplied with the watch or one confirmed compatible with its exact model. The accessory type varies: Samsung lists magnetic wireless charging pads for Galaxy Watch4 and later families and several earlier models, while the original Galaxy Watch uses a wireless charging dock. Check Samsung Canada’s model-by-model charger guide before using or replacing an accessory.

Galaxy Watch screen is black or frozen: force a restart

If the watch is unresponsive rather than simply powered off, Samsung Canada’s current procedure is to press and hold Home/Power and Back at the same time for at least seven seconds, until the screen goes dark. Release both buttons; the screen should light and display a reboot message. Samsung says this forced restart does not erase personal data or reset the watch. It is a restart, not the ordinary one-button power-on procedure or a factory reset.

  • Confirm the charger is connected, properly aligned, and compatible with the exact watch model.
  • Leave the watch charging for a few minutes, then retry the normal Home/Power startup.
  • If it remains unable to charge or respond, contact Samsung support or arrange service rather than attempting an unsupported repair.
