Troubleshooting guide for Samsung Galaxy Watch

Last Update date : Apr 20. 2021

Before contacting a Samsung Service Center, please attempt the following solutions.

Galaxy Watch does not turn on

  • When the battery is completely discharged, your Galaxy Watch will not turn on. Fully charge the battery before turning on the Galaxy Watch.
  • Use only Samsung-approved chargers, batteries, and cables. Unapproved chargers or cables can cause the battery to explode or damage the Watch.
  • Before charging the battery, ensure that the charging terminals of the Watch and the wireless charger dock are free of foreign material, such as sweat, liquid, or dust. Clean the charging terminals with a soft dry cloth. 
  • If the device is not turned on after charging for enough periods, please visit Samsung Service Centre with your device for further assistance.
Touchscreen responds slowly or improperly

  • If you attach a screen protector or optional accessories to the touchscreen, the touchscreen may not function properly.
  • If you are wearing gloves, if your hands are not clean while touching the touchscreen, or if you tap the screen with sharp objects or your fingertips, the touchscreen may malfunction.
  • The touchscreen may malfunction in humid conditions or when exposed to water.
  • Restart your Galaxy Watch to clear any temporary software bugs.
  • Ensure that your Galaxy Watch software is updated to the latest version.
  • If the touchscreen is scratched or damaged, visit a Samsung Service Center.
Galaxy Watch freezes or has errors

 If the problem is still not resolved, contact a Samsung Service Center.

Restart the Galaxy Watch

If your Galaxy Watch freezes or hangs, you may need to close apps or turn off the Galaxy Watch and turn it on again.

Force restart

If your Galaxy Watch is frozen and unresponsive, press and hold the Home key (Power key) for more than 7 seconds to restart it.

Resetting the Galaxy Watch

If the methods above do not solve your problem, perform a factory data reset. On the Apps screen, tap (Settings) → General → Reset.


Before performing the factory data reset, remember to make backup copies of all important data stored in the Galaxy Watch.

Cannot locate Galaxy Watch with another bluetooth device

You can connect the Bluetooth headset to listen to music and have phone conversations through it. If the Bluetooth headset cannot locate your Galaxy Watch, follow these steps:

  • Ensure that the Bluetooth wireless feature is activated on your Galaxy Watch.
  • Reset your Galaxy Watch and try again.
  • Ensure that your Galaxy Watch and the other Bluetooth device are within the Bluetooth connection range (10 m). The distance may vary depending on the environment the devices are used in.
  • Restart both devices and launch the Galaxy Wearable App on the Mobile Device again.

If the tips above do not solve the problem, visit a Samsung Service Center with your device for further assistance.

Calls are not connected

  • Ensure that your Galaxy Watch is connected to a mobile device via Bluetooth. If your Galaxy Watch is connected to your mobile device remotely, you cannot receive incoming calls.
  • Ensure that your mobile device and Galaxy Watch have accessed the right cellular network.
  • Ensure that you have not set a call barring for the incoming phone number on the mobile device and Galaxy Watch.
  • Ensure that you have not set a call barring for the phone number you are dialling on the mobile device and Galaxy Watch.
  • Check if do not disturb mode, goodnight mode, or theatre mode is activated. If one of these modes has been activated, the touchscreen does not turn on during incoming calls.
  • Rotate the bezel or press the Home key or Back key to turn on the screen and check the incoming call.
Battery depletes fast

  • When you expose the Galaxy Watch or the battery to very cold or very hot temperatures, the useful charge may be reduced.
  • Battery consumption increases when you use some apps.
  • The battery is consumable and the useful charge will get shorter over time.
A small gap appears around the outside of the Galaxy Watch case

  • This gap is a necessary manufacturing feature and some minor rocking or vibration of parts may occur.
  • Over time, friction between parts may cause this gap to expand slightly.
Heart rate is inaccurate

Check first whether you have worn the Galaxy Watch correctly.

When you activate the auto heart rate tracking feature, or when the Galaxy Watch recognizes your exercise, the Galaxy Watch will automatically track your heart rate. When measuring your heart rate, wear the Galaxy Watch snugly on your arm above your wrist as shown in the figure below.



  • The accuracy of the heart rate sensor may be diminished depending on measurement conditions and surroundings.
  • Use the HR feature only for measuring your heart rate.
  • Do not look directly at the heart rate sensor’s lights. Doing so may impair your vision.
  • Cold ambient temperatures may affect your measurement; during winter or cold weather.
  • Take heart rate measurements when you are seated and relaxed.
  • If you receive a reading that is very different from your expected heart rate, rest for 30 minutes and then measure again.
  • Smoking or consuming alcohol before taking measurements may cause your heart rate to be different from your normal.
  • Do not talk, yawn, or breathe deeply while taking heart rate measurements.
  • Heart rate measurement is affected by physical factors such as light absorption and reflection, such as blood circulation/blood pressure, skin condition, and location and concentration of blood vessels.
  • Clean the heart rate sensor when it is dirty.
  • If your device becomes hot to the touch, please remove it until it cools.
