Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsTo open Recovery on a Galaxy Watch4 or Watch4 Classic, first enter Reboot mode: hold the Home/Power and Back buttons until “Rebooting…” appears, release them, then immediately tap Home/Power repeatedly. Highlight Recovery and hold Home/Power to select it. Entering Recovery does not erase the watch; a factory reset is a separate, destructive choice inside Recovery.
Before you begin
These instructions apply to Galaxy Watch4 and Galaxy Watch4 Classic, including Bluetooth and LTE models. The upper physical button may be called Home, Power, or Home/Power in Samsung instructions. Menu wording and available options can vary by model, software version, phone, and wireless provider.
- If possible, charge the watch before troubleshooting.
- Recovery is a maintenance environment, not a reset command. Data is erased only if you select a wipe or factory-reset option.
- If you expect to reset the watch and it is still accessible, back it up through Galaxy Wearable first. Data that has not synchronized or been backed up may not be recoverable.
Samsung’s instructions for the force restart and boot-loop troubleshooting and watch reset procedure are the basis for the steps below.
Enter Recovery mode
- Force a restart: Press and hold the Home/Power and Back buttons together. Keep holding even if the screen appears frozen. On some watches, “Rebooting…” can take up to about 30 seconds to appear.
- Release at “Rebooting…”: As soon as the message appears, release both buttons.
- Open Reboot mode: Immediately press and release Home/Power repeatedly until the Reboot mode menu appears. Samsung does not specify a guaranteed number of presses; timing matters more than a fixed count.
- Highlight Recovery: Keep pressing Home/Power until Recovery is selected or highlighted.
- Select it: Press and hold Home/Power. Release the key when the display turns dark, then wait for the recovery screen.
The first menu is Reboot mode, not Recovery itself. The distinction matters: the two-button hold starts a force restart, repeated Home/Power presses open the menu, and selecting Recovery enters the maintenance environment.

Navigate Recovery and leave without wiping
On Wear OS recovery screens, Samsung instructs users to swipe down to move to an option and swipe right to select or confirm it. Follow the labels shown on your watch because presentation and wording can vary by software build.
If you only wanted to inspect Recovery or restart the watch, do not select Wipe data/factory reset. Use the on-screen reboot option if one is available; its label may vary, and commonly displayed wording includes “Reboot system now.” If the watch stops responding in the menu, hold Home/Power and Back together to force a restart.
Do not assume every Watch4 build has a Wipe cache partition option. Use a cache-related option only if it is clearly displayed on your watch, and do not confuse it with a factory reset.

Factory-reset from Recovery
Warning: A factory reset is destructive. It deletes personal data, installed apps and their data, settings, and the existing phone pairing. Back up through Galaxy Wearable first if the watch is accessible; unsynchronized or unbacked-up data may not be recoverable. A reset does not recover a forgotten PIN, and account or ownership verification may still be required during setup.

For a connected watch, Samsung’s boot-loop reset guidance says to unpair the current Bluetooth connection first for that reset path. Afterward, pair the watch again through Galaxy Wearable rather than relying on the old pairing.
If Reboot mode or Recovery will not appear
The watch boots normally
The Home/Power key may not have been pressed quickly enough after “Rebooting…” appeared, or it may have been held rather than tapped. Let the watch finish booting or repeat the force restart. Release both buttons at “Rebooting…” and begin tapping Home/Power immediately. Tap repeatedly rather than relying on a fixed count.

The watch is frozen or stuck in a boot loop
Try the force restart first. If normal access returns, Samsung recommends checking for software updates and removing recently installed apps that could be causing trouble. If the problem continues, Recovery offers reset options, but a factory reset is an escalation—not a guaranteed fix for every software or hardware fault.
The buttons do not respond
Charge the watch, then retry. Check whether a button is obstructed or physically stuck; dirt or residue around a button can affect response. Clean only the exterior gently—do not insert sharp tools or liquid into the button gap. If a button is damaged or remains stuck, contact Samsung Support for service.
An unexpected boot screen appears
Do not select unfamiliar options such as Download mode unless you have a specific, verified reason. If you cannot identify the screen or the watch appears stuck there, holding both physical buttons to restart is the least destructive first step when the buttons work.

After a reset
The watch returns to setup and needs to be paired again through Galaxy Wearable. Restore any backup that is available, then check for software updates. If you have an LTE model activated using a carrier QR code, Samsung says a new QR code from the carrier may be needed to reactivate service; this is not stated as inevitable for every LTE reset.
For general Wear OS context, Google explains that a factory reset removes watch data, apps, settings, and phone pairing in its factory-reset guidance.
