You pressed the Home button on your Galaxy Watch8 (44mm), the Samsung logo flashed on, and then it just sat there. The watch never finishes booting, the screen stays frozen on that logo, and tapping or swiping does nothing. It is a frustrating state because the watch looks like it is trying to start, yet it never reaches the watch face, and you cannot tell whether the cause is a drained battery, a software hiccup, or a hardware fault.
The good news is that a watch stuck on the logo is usually recoverable without a trip to a service center. The fixes below are ordered from the safest and easiest to the most drastic, so start at the top and stop as soon as your watch boots normally. Everything here applies to the Galaxy Watch8 (44mm), both the Bluetooth/Wi-Fi model (SM-L330) and the LTE model (SM-L335), running Wear OS 6 (powered by Samsung) with One UI 8 Watch.
Rule Out a Dead Battery on the Charging Dock First
Before you assume the worst, give the watch a long charge. A deeply drained battery can leave the watch stuck part-way through boot, showing the logo without ever completing startup. This is the least invasive step and it fixes the problem more often than you would expect.
- 1.Use the charging dock that came with your watch, connected to an approved Samsung adapter.
- 2.Place the watch on the dock, making sure it is seated correctly.
- 3.Allow the watch to charge for at least 1 hour.
- 4.If no charging indicator appears, press the Home/Power key once to check.
- 5.Remove any metal band if it is interfering with the charging connection.
- 6.After the hour, press the Power key to try to turn the watch on.
If the watch boots normally after charging, you were dealing with a low-battery boot loop and nothing more drastic is needed. If it still hangs on the logo, move on to the next fix.
Force Restart With the Home and Back Buttons
A force restart clears a temporary software freeze without erasing any of your data. The Galaxy Watch8 has two physical buttons on the right side, the Home button (upper-right, also called the Power button) and the Back button (lower-right). You will use both together.
Press and hold the Home button and the Back button simultaneously for at least seven seconds. The screen will turn black and the Samsung logo appears, which means the watch is restarting. Release both buttons once you see the logo.
On some models you continue holding until the screen displays "Rebooting...", and that prompt can take up to 30 seconds to appear, so do not let go too early. If the watch reboots past the logo and reaches the watch face, the freeze is cleared. If it loops back to the stuck logo, continue down the list.
Install Any Pending Software Update
Once your watch boots past the logo, even briefly, it is worth checking for a software update. Updates frequently fix the stability problems that cause restart loops in the first place, so applying one can stop the issue from coming back.
From your phone, open the Galaxy Wearable app and go to Watch settings > Watch software update > Download and install. The watch needs at least a 30% charge for the update to run, so keep it on the dock during the process.
You can also check from the watch itself by going to Settings > General > Watch software update. Let any available update finish completely, and avoid removing the watch from the charger while it installs.
Uninstall an App You Added Right Before the Trouble Started
If your watch only began getting stuck after you installed something new, a misbehaving third-party app may be triggering the boot loop. Removing that recent app is a quick, non-destructive thing to try before you consider resetting anything.
You can uninstall it from the Galaxy Wearable app on your phone, or directly on the watch from the apps screen. Think back to what you added most recently, remove it, and restart the watch to see whether the logo screen clears.
Clear the Galaxy Wearable App Data on Your Phone
The companion app on your phone keeps state about your watch, and if that state becomes corrupted it can interfere with the watch finishing its boot. Samsung's boot-loop guidance says that when the watch is connected to your phone, you should clear the data for the Galaxy Wearable app and then reconnect.
Clearing the app data resets the corrupted companion-app state without touching the watch itself. After you clear it, reconnect the watch through the Galaxy Wearable app and check whether it now boots all the way to the watch face.
Inspect and Clean the Charging Dock
If the watch still will not power on properly, the problem may be a poor charge rather than software. A faulty or dirty dock can prevent the watch from getting a clean, full charge, which keeps it from booting reliably.
Check both the dock and the back of the watch for physical or liquid damage, cracks, or bent parts. Clean both surfaces with a soft, dry cloth so the charging contacts make solid contact. Then charge again and attempt to power the watch on.
Factory Reset and Re-Pair as a Last Resort
If nothing above has worked, a factory reset is the final software step. Be aware this is destructive. As Samsung states, "All of your personal data will be removed and the watch will restore back to its default settings." Back up anything you can first, and only proceed if the earlier fixes failed.
If the watch can reach its menus, reset it directly.
- 1.On the watch, go to Settings > General > Reset.
- 2.Tap the checkmark and follow the on-screen instructions.
If the watch cannot reach its menus because it stays stuck on the logo, use Samsung's boot-loop recovery method instead.
- 1.Unpair the watch in your phone's Bluetooth settings. To unpair, tap Bluetooth, tap the Settings icon next to the watch, then tap Unpair. Some watch data may remain on the phone until you unpair.
- 2.Power off the watch, then power it back on by holding the Power key until "Rebooting..." displays.
- 3.Repeatedly press and release the Power key to enter Recovery mode.
- 4.Select and confirm Factory reset.
After the reset, re-pair the watch using the Galaxy Wearable app, or on the watch go to Settings > General > Connect to new phone > Continue.
When to Let Samsung Take Over
Some stuck-on-logo situations point to hardware, not software. If the watch cannot restart because of physical damage, such as a stuck button, or if the dock is undamaged but charging still fails after you have cleaned and inspected everything, the problem is likely hardware.
At that point, stop troubleshooting and get it looked at. You can visit a Samsung walk-in service center or schedule a repair online. Bring the charging dock with you, since a dock that fails inspection can be the real culprit behind a watch that never finishes booting.
One note about compatibility while you sort this out. The Galaxy Watch8 (44mm) is not compatible with iPhone or iOS. It runs Wear OS, which relies on Google Play services, so it must be paired to a smartphone running Android 11.0 or above (with at least 1.5 GB of RAM) using the Galaxy Wearable app. If you were trying to set it up or recover it through an iPhone, that will not work, and an Android phone is required for every pairing and reset step above.
Frequently Asked Questions
How long should I hold the buttons to force restart a stuck Galaxy Watch8?
Press and hold the Home button and the Back button at the same time for at least seven seconds, until the screen turns black and the Samsung logo appears, then release both. On some models you hold until "Rebooting..." displays, which can take up to 30 seconds, so do not let go too soon.
Will a force restart erase my data?
No. A force restart using the Home and Back buttons simply reboots the watch and does not remove your data. Only a factory reset erases the watch, and Samsung warns that with a reset, "All of your personal data will be removed and the watch will restore back to its default settings."
My watch will not turn on at all. What should I try first?
Charge it before anything else. Place it on the charging dock that came with the watch, connect to an approved Samsung adapter, and allow the watch to charge for at least 1 hour. If no charging indicator appears, press the Home/Power key once, and remove any metal band that may interfere with charging, then try the Power key again.
Can I pair the Galaxy Watch8 with an iPhone?
No. The Galaxy Watch8 (44mm) runs Wear OS, which depends on Google Play services that are not supported on iOS, so it is not compatible with iPhone. It must be paired to an Android phone running Android 11.0 or above using the Galaxy Wearable app.
What do I do if the watch is still stuck after a factory reset?
If the watch still will not boot after a reset, or it cannot restart due to physical damage such as a stuck button, the issue is likely hardware. Visit a Samsung walk-in service center or schedule a repair online.
