You glance down at your Galaxy Watch Ultra and the screen is on. The time is right. The step counter is frozen at some number you don't recognize. But tapping, swiping, pressing, nothing happens. The Home button clicks. The Back button works. The Quick Button still triggers its shortcut. Just the touch screen isn't listening. Most of the time, this isn't a hardware fault, and you can fix it in a few minutes without unpairing anything.
The Galaxy Watch Ultra uses Wear OS 6 with One UI Watch 8, and its sapphire crystal display is tougher than previous Galaxy Watch glass. But that durability doesn't protect against software glitches or the gunk that builds up from a long run or a sweaty workday.
Wipe the Screen Down
Start with the simplest thing. Take the watch off, rinse it under lukewarm tap water for a few seconds, the 10ATM water resistance rating means it's fine, then dry it with a soft microfiber cloth. Skin oil, sunscreen, dried salt from a swim, or even a thin layer of sweat can interfere with capacitive touch on the Ultra's display.
If the screen responds after a clean dry, you're done. The Ultra's sapphire crystal is less prone to scratches but still attracts oils just like any glass surface, especially after a workout or outdoor activity.
Turn Off Touch Lock and Water Lock
Galaxy Watch Ultra has a Touch Lock mode that disables the screen during water activities. If you were swimming, showering, or just rinsed the watch and don't remember turning it off, Touch Lock might still be active.
Look for a small water droplet or lock icon at the top of the watch face. To disable it, press and hold the Home button (top right), then tap Unlock on the prompt. If the touch screen isn't responding to that, use the Back button to navigate to Settings, scroll with the Home button, and toggle Touch Lock off manually. Or simply restart the watch using the physical buttons, that clears the lock state.
Force Restart the Watch
If the screen is frozen in an app or the touch input stopped mid-stride during a workout, force restart. Hold the Home button (top right) and the Back button (bottom right) together for at least 7 seconds. Let go when the Samsung logo appears. The Quick Button in between them doesn't do anything during the restart sequence.
This reboot takes about 30 seconds and doesn't erase any data. After it boots, try tapping on the watch face. In most cases, touch comes back cleanly. This one fix alone saves most Galaxy Watch Ultra touch issues before they become a bigger headache.
Remove Any Screen Protector
The Galaxy Watch Ultra ships with a sapphire crystal display that's already very scratch-resistant. But many users add a screen protector anyway. The problem is that not all protectors fit the Ultra's slightly raised bezel and flat display correctly. A protector that's too thick or misaligned can deaden touch sensitivity, especially around the edges or on the Quick Button side.
Peel off any screen protector or case wrap that covers the display. Test touch directly on the sapphire glass. If it works fine without the protector, you need one specifically designed for the Watch Ultra's dimensions, not a generic round protector meant for older Galaxy Watch models.
Check for a Software Update
One UI Watch 8 has shipped a few patches since the Galaxy Watch Ultra launched in 2024. Some of those updates fixed touch driver stutter and unresponsive gesture issues. If you're running an older build, an update might resolve it without any other steps.
Use the physical buttons to navigate since touch isn't working. Press the Home button to open the app drawer, scroll to Settings, press the Home button to select it, then scroll to Watch software update and select Download and install. Or open the Galaxy Wearable app on your phone, tap Watch settings > Watch software update, and push the update from there, no watch touch input needed.
Disable Touch Sensitivity If It's On
Galaxy Watch Ultra has a Touch sensitivity setting designed for use with gloves or screen protectors. When this is on, the watch is more sensitive to electrical interference and accidental touches. If you don't actually need it, it can cause missed taps or false touches.
On the watch, go to Settings > Display > Touch sensitivity and toggle it off. If the screen isn't responding, do this from the Galaxy Wearable app on your connected phone: open the app, tap Watch settings > Display, and turn off Touch sensitivity there.
Try Touch in Different Parts of the UI
Before assuming the digitizer is dead, test touch across different screens. From the watch face, swipe down for notifications, swipe up for the quick panel, and press the Home button to open the app drawer. If any of these gestures register, even if others don't, the touch hardware is working, and the problem is isolated to a specific app or screen state.
If only one app is freezing, force close it by pressing the Home button twice to open the app switcher, scroll to the problematic app, and swipe it away or tap the close button if touch works there. If no part of the UI responds, a force restart is your next step. If even that fails, unpair and re-pair through the Galaxy Wearable app.
Unpair and Re-pair via Galaxy Wearable
If touch is still dead after a force restart and all the checks above, unpair the watch. This wipes the device to factory condition and clears any corrupted touch-related settings deep in the OS.
Open the Galaxy Wearable app on your phone, tap the three dots in the top-right corner, select Unpair, and confirm. The watch resets automatically. After it restarts, pair it again with your phone by following the setup flow in the app. Choose Restore from backup to bring back your apps, watch faces, and health data. After the re-pair, test touch immediately on the setup screens, if it works there, the hardware is fine and the software was the issue.
