Samsung Galaxy Watch not turning on or shows a black screen? How to fix it

Is your Samsung Galaxy watch is suddenly stuck on a black screen and won’t turn on when you tap the display or press the buttons? Sadly, you are not alone.

Samsung’s Galaxy Watch is a top smart and fitness watch, rivaling the best Apple Watch. A high price means it has a lot to prove. So, when your Samsung Galaxy Watch suddenly doesn’t turn on, gets stuck on a black screen, and is unresponsive to your taps, it’s really frustrating!

The 361mAh battery capacity of the Samsung Galaxy Watch 4 and the 340mAh of the  Galaxy Watch 3 and Galaxy Active Watch 2 suggest that the battery capacity on Samsung’s Galaxy watches is solid and might not be the main reason for your watch not turning on.

Try a forced restart if you can hear sounds or feel the watch vibrate

If you feel your watch vibrate or hear it make some sounds, that’s good news and means that your watch is on. However, the screen is not turning on.

To help solve this, try a forced restart

Samsung Galaxy watch 4 forced restart

  • To do this, press and hold both of the buttons on your watch, and don’t let go of those buttons until you see the Samsung logo on your watch’s screen.
  • If you can’t press a button in, make sure there’s nothing stuck or blocking it by cleaning the button(s) and then try to force a restart again.

Another option is to place the watch on its charger and repeat the steps for a forced restart. You may need to go through these steps several times before your watch’s screen turns on. So if it failed on your first attempt, try a couple more times.

Thinking of replacing your watch’s battery? It’s likely not necessary Samsung Galaxy back side

The chances are that there is an easier fix for this issue with your Galaxy Watch than replacing the battery.

In our experience with smartwatches, we often find that this problem happens when a faulty connection problem is related to the charging cradle.

This article looks at some of the main issues that might lead to your Samsung Galaxy watch not turning on and provide you with some helpful tips that save you time and dollars.

Start with the charging dock for your Galaxy Watch 

  1. The first thing you can do is leave your Galaxy Watch on the charger overnight and charge it to 100%. The charge time for the watch depends upon the watch’s condition and the charger’s condition. There is a chance that your watch has completely drained its battery. Samsung Galaxy charge to 100%
  1. If you have already tried charging the watch overnight and had no success, there is a chance that the outlet that you regularly use is not operating. We suggest that when you charge your watch overnight, make sure to use an alternate outlet or power source that you know works correctly. 
  1. Inspect the Samsung Wireless charger cable. If you see any signs of fraying, it may suggest that the charging cable has run its course, and you need a new Samsung Charging wireless cable. If getting a replacement isn’t possible, use electrical tape or Sugru over the fraying portion and try charging. Damaged charging cable
  1. And the obvious? Are you using the correct wireless charger? In our household, we use different smartwatches, and most of these chargers look the same. Flip your charger over and make sure that you use the correct charger to charge your Galaxy watch. Old Galaxy Watch Active chargers may not charge your newer Samsung Galaxy watches. Samsung Galaxy Watch Wireless charging cable

Galaxy Watch not turning on due to faulty charging

  1. Start charging your watch using the wireless charger and let it sit on the cradle for a couple of hours. 
  2. After an hour or two, if you don’t see the charging indicator show up on your watch’s display, press the Power button on your watch while leaving it on the charger. Does your watch turn on to show the power indicator? If it does, let the charging process continue until the watch is fully charged.
  3. After an hour or two of charging, if your Galaxy watch does not show charging status when the Power button is pressed but appears warm to touch, it may mean that your Galaxy watch is too hot (thermal shutdown mode.) Your watch cannot charge until it cools down. Remove the watch, wait until it cools off, and then place it on the charger. Runaway apps can cause the watch to enter into thermal shutdown mode.
  4. Verify nothing is between charger and device, i.e., no dust, tape, etc. We have seen many instances where there is accumulated dust or debris on the charger, or the back of your smartwatch has collected dust from use. Use a clean piece of cloth to clean out any dirt from the charger and the back of the watch, and then try charging. 
  5. Try changing the charger’s power source, i.e., move to wall outlet from laptop. When charging via PC or laptop, the device must be ON and not on sleep mode. You can verify that the charger gets power by using the USB head on another device or outlet.

If you notice that your watch is charging but charging very slowly, then it may be time to get a replacement charging cradle for your Galaxy Watch. 

Check for stuck buttons

With everyday use of the watch, the side buttons on the watch can also accumulate dirt or debris over time. If you notice that the side buttons aren’t working or require multiple attempts, clean them with rubbing alcohol. 

Generally, put a little rubbing alcohol on your finger and rub around the buttons, push them repeatedly, in an attempt to try and loosen anything that’s built up and prevent them from depressing properly.

What does the charger’s LED light mean?

If your charger has an LED light and shows different color lights, you can interpret this as:

  • Red: Charging
  • Green: Fully charged
  • Red > Green > Orange: Standby mode
  • Orange: Connected to a low-power adaptor

This is true with third-party chargers as well. It is best to use the Samsung-approved charger for your Galaxy watches.

Samsung Galaxy Watch shows a black screen and is unresponsive Turn Samsung Galaxy off while charging

If your notice that your watch is charging ok, but the screen turns black and unresponsive, it is definitely not the charging circuitry or battery causing this issue.

  • To confirm this, you need to open up the Galaxy Wear app on your phone.
  • Go to the app’s Home page and look at the battery information at the top of the screen. 

If the battery percentage is greater than 20 – 25% and your watch shows a black screen or is not responsive to the touch, a soft reset helps fix this issue.

Reset Watch on the charger by pressing and holding the power button
  1. Press and hold the Power button on the watch while it is charging
  2. You see the ‘Power Off’ button show up on the Options screen
  3. Tap on “Power Off”
  4. Once the watch is powered off, press and hold the Power button until the Samsung Galaxy logo appears, then release the button.
  5. This softest process should help fix the unresponsive issue on your watch.

The other way to achieve this is doing it using the long-press method.

  • While your Galaxy watch is charging, hold down the power button and keep it pressed until your watch shows that it’s rebooting.
  • After about 5-10 seconds, it’ll reboot automatically, and your watch should work normally.
  • If it doesn’t show that the watch is rebooting, press and hold the Power and Back buttons simultaneously until you see a message that it’s rebooting. 

Power Saving Mode and charging

Sometimes you may have to leave the watch on its charger overnight or more before you can attempt to restart it. 

This is especially true if your watch was already in power-saving mode before losing all the charge. 

Some users have suggested that when the wireless charger for the watch is not showing signs of charging, you can try the Wireless Power share on the back of your Galaxy S20+ phone or another Galaxy phone with wireless power share and give it a try.Use Samsung Wireless Power share to charge the watch

If your watch shows the charging indicator when getting power via the Wireless Power share of your phone, use the power button on the watch to soft reset the watch.

If the battery is extremely low, as in this case, the watch display may remain blank for up to 5 minutes before a low battery image appears. It may take 15 minutes to 2 hours before the device can be powered up using the normal wireless charger.

Ideally, to avoid these unresponsive issues on your Galaxy watch, make sure not to allow the device to drain out its charge completely. 

Galaxy Watch charging but keeps blinking

Some users had the issue where their watch screen was unresponsive even to the power button. There was no way of finding out if the watch was getting into reset/ reboot mode.

Other users found that it charges when they put the watch on the charger, but the watch screen keeps on blinking.

If this happens to you, you can use the ‘Reset’ feature from the app on your phone and reset the Samsung Galaxy Watch.

There’s a good chance that even though your watch’s screen is not turning on, it is still connected to your phone via the Bluetooth connection.

Backup first! 

We recommend that your first back up the data on your watch before you do the Reset if you can.

  • Open the Galaxy Wearable app on your paired phone.
  • Tap Watch settings, and then tap Account and Backup.
  • Tap Backup data.
    • Any Music you saved on your watch is not backed up.
    • Backups include app data and app settings, your watch faces and their settings, and any customized system settings.

How to reset your Samsung Galaxy Watch using the Wearable app

  1. Open the Galaxy Wearable app on your Phone.
  2. Some models require you also to tap Watch settings.
  3. Tap on General.Reset Samsung Galaxy Watch from phone
  4. And then choose Reset.Samsung Galaxy Watch not responsive

When you reset your watch, it returns the watch to its factory defaults. So all your personal information and any settings or personalized features are lost UNLESS you backed it up first.

If you don’t have access to the Wearable app or your watch doesn’t show up in it, you can also try to manually reset the Galaxy Watch using the buttons on the watch and enter reboot mode. This might jump-start your watch to show its screen!

  1. Press the Home key until Rebooting displays on the watch’s bottom.
  2. Immediately press the Home key repeatedly until you see the REBOOT MODE menu on your watch’s screen.
  3. Press the Home key multiple times until you select Recovery. Samsung Galaxy smartwatch REBOOT MODE
  4. Press and hold the Home key and keep holding it until you see Rebooting at the bottom of the watch face.
  5. The Galaxy Watch 4 model shows an additional menu:
    1. Swipe down and select Wipe data/factory reset, then swipe right. 
    2. Swipe down again to select Factory data reset, and swipe right again to execute the reset.
    3. Once the reset completes, swipe right to reboot the watch one more time.

Restore your Galaxy Watch’s data after a reset

If you need to factory reset your Samsung Watch, you can restore any data from your backup if you choose.

  • Open the Galaxy Wearable app on your paired phone.
  • Tap Watch settings, and then tap Account and Backup.
  • Choose Restore data.

    • HI Gina,

      Sorry to hear that your Samsung Watch isn’t responding. Can you please let us know what watch model you use?

  2. My Samsung Active Watch 2 is only 2 months old and suddenly the screen is black and will not work no matter what I do.

    I tried holding down both buttons while charging and not charging. Was at 100% so it is not the battery.

    Followed another suggestion about doing a reset but now all that’s accomplished is me not being able to see anything about my watch on my phone.

    The screen doesn’t work at all so I can’t see the 6 digit code to connect my phone n watch. I know it’s still on bcuz it vibrates. HELP!

    • Hi Dreama,

      We are very sorry to hear that your Samsung Active 2 Watch isn’t turning on. Please try and press&hold the bottom button (called the Home button) and maintain this hold until the screen reactivates (hopefully.) You may need to press and hold that button for about 30 seconds to get your watch to reboot. If you hold it longer than 45 seconds and still nothing happens, then release it.

      • I have the same problem and also tried the reset on my phone and now the watch doesn’t show on my phone either. It vibrates so I know it’s on but nothing else. Have tried all of the suggestions and nothing has worked. My watch is just over 2 years old

        • Hi Melanie,

          Oh, no! Sorry to learn that your watch is stuck in a black and unresponsive screen. Can you let us know what model (Galaxy Watch 3, Active 2, etc) you have some we can provide some tips specifically for that model.

          Does the Galaxy Wearable app recognize your watch?

    • Hi Josh,

      Sorry about your watch being stuck on a black screen after giving Bixby a try. Try this: in the Wearable app > Watch Settings > Apps > choose Bixby. At the bottom, tap Force stop or Uninstall.

      I’m not exactly sure what’s going on with your watch, so here’s some additional suggestions:

      1) Open the Wearable app > Watch Settings > Display and toggle on Always on display (or if that’s on, toggle it off and on) and toggle on Touch screen to wake. Just the brightness and see if that makes a difference

      2) In the Wearable app > Watch Settings > Advanced features, choose a different action for double press and press and hold

      3) In the Wearable app > Watch Settings > Accessibility, toggle off TalkBack if it’s on

      4) Open the Wearable app and use a different watch face

      Hope something helps!


  4. Hi, I have an active 2 galaxy watch and the screen is black with blue lines across the middle. I have tried resetting it, and now , even though my phone can find it, I cannot reconnect as I can’t read anything on the watch

    • Hi Gary,

      Try rebooting it using reboot mode and see if the reboot screen shows up and is legible.

      1) On your galaxy Active 2, press both buttons and wait for the word “rebooting” to appear on its screen (hopefully)

      2) Once you see Rebooting, release both buttons and then immediately press the Home button repeatedly and keep doing this until you see a Reboot Mode menu on the watch’s screen

      3) Choose Continue from the menu and wait for your watch to reboot

      4) Once your watch reboots, open the Wearable app and see if you can connect it. If the Wearable app doesn’t recognize your watch, run through the steps again but choose Recovery instead of Continue from the reboot menu.

      Keep us posted if this doesn’t work or if your watch doesn’t show the reboot mode menu.

  5. I have a galaxy active, on the charger it shows charging, but it’s very dark and the icon is green and at times blue but it’s so dark.

    Once on the charger, the screen goes blank and I cannot see anything. The app does show my watch is connected too.I’ve tried everything.

    • Hi Michelle,

      Oh, I am so sorry to hear that your Samsung Galaxy Active watch’s screen isn’t turning on. Since you mention that you tried everything, I assume you tried to restart (reboot) your watch and that the problem remained.

      Although uncommon, let’s check if you turned on some accessibility settings. Open the Wearable app, choose Watch Settings (you might not see this option,) then select Accessibility. Tap Screen reader and toggle Voice Assistant off if it’s on. If you can access Settings, tap that and toggle everything off.

      Return to the Accessibility menu and tap Visibility enhancements. If anything is on, toggle it off.

      Now, go back to Watch Settings and choose Display. Check the level of screen brightness and turn it up. Toggle off auto low brightness.

      Hopefully, one of those was the culprit. If not, talk to Samsung Support–there may be some damage and you might need a repair.

  6. I have a Samsung galaxy watch active.

    Got it at Xmas and it’s stuck on a black screen. I’ve tried to reboot and also did a reset on my phone, but now it’s not connecting to my phone and is still on the black screen.

    It vibrates when I put it on to charge, but still a black screen.

        • HI RT,

          Sorry to hear that your Samsung watch isn’t turning on or is stuck on a black screen. Did you update any apps or the software recently or add any new apps to the watch?

  7. Samsung Gear Sport

    Blank face, fully charged. Tried all the above steps, no luck. Tried resetting using the Wearable app. Cannot reconnect.

    App wants me to confirm pairing number on watch, but watch face blank. I can feel/hear watch vibrating waiting for pairing permission. Tried hard reset, pressing both buttons simultaneously but nothing ever happens.

    • Hi Seif and Mike M,

      If none of the tips worked and your screen still isn’t showing anything other than a black screen, I would contact Samsung Support.
