You finished a run on your Galaxy Watch Ultra, glanced down to check your pace and distance, and the session was nowhere to be found. Maybe the watch logged nothing at all, maybe it missed your heart rate, or maybe it quietly recorded a drive to the store as a "workout" you never did. The good news is that this watch is built to track exercise. It records sessions in the built-in Samsung Health app, follows pace, distance, and heart rate, has dual-frequency multi-band GPS for route accuracy, and even has a Multisport workout tile that is exclusive to the Ultra. When tracking goes wrong, it is almost always a fit, settings, permission, or software hiccup, and the fixes below move from the quickest checks to the official reset and repair path.
Start With How the Watch Sits on Your Wrist
Before touching any settings, look at the simplest cause, which is how the watch is worn. Most missing or wrong workout data comes down to fit, because the sensors on the back need steady skin contact to read your steps and heart rate.
Samsung's guidance is to wear the watch snugly above the wrist, and not to fasten the band too tightly. If the watch is too loose, or the back sensor is dirty, it has difficulty tracking steps and heart rate accurately.
- 1.Wipe the heart-rate sensor on the back of the watch with a soft, clean, dry cloth.
- 2.Remove any protective plastic still covering the sensor.
- 3.Clear obstructions such as body hair or dirt between the sensor and your wrist.
- 4.Use only Samsung-approved bands for your model, and position the watch snugly just above the wrist bone.
Record the Session Yourself Instead of Waiting for Auto-Detect
If a workout simply never appears, the safest habit is to start it manually rather than trusting the watch to notice on its own. Automatic detection has a built-in delay, so short sessions can slip through the cracks if you rely on it.
To start tracking by hand on the Galaxy Watch Ultra, swipe up to access the Apps screen, and then open Samsung Health. Swipe to and tap Work out, tap the workout of your choice, and allow any permissions if needed, then wait for the countdown to finish. To control or finish the session, swipe right on the watch's screen and tap the Finish icon.
Keep in mind that automatic workout detection only kicks in after you have been moving for about 10 minutes, so a quick session can be missed entirely if you wait for the watch to catch on.
Turn On or Repair Automatic Workout Detection
If you would rather the watch start tracking on its own and it is not doing so, the detection feature may be switched off or limited to the wrong activities. You can fix both from one screen.
- 1.Open Samsung Health on the watch.
- 2.Tap Settings, then tap Workout detection (this is also shown as "Activities to detect").
- 3.Tap the switch next to On so it turns blue.
- 4.Make sure the switch for Alerts is on.
- 5.Tap Activities to detect and select the activities you want.
Remember that this feature needs about 10 minutes of activity before it triggers. If you have the opposite problem, where driving or other everyday movement is being logged as exercise, use the same screen to turn detection off.
Confirm the Quick Button Launches Your Exercise
On the Galaxy Watch Ultra, the Quick button can launch a workout, which is handy mid-stride. If pressing it does not start tracking the way you expect, the button may be assigned to a different action or exercise.
To set it from the watch, go to Settings, then Buttons and gestures, then Action, tap the settings icon next to Samsung Health, select the exercise from the list, then scroll to the bottom and tap OK. You can also set it to start on a Short press or Double press using the "Start action with" option.
You can do the same thing from your phone if that is easier. In the companion app, go to Galaxy Wearable, then Watch settings, then Buttons and gestures, then Action, tap the settings icon, tap the exercise you want the button to launch, and tap OK.
Grant Location Access So GPS Can Lock On
Missing distance, pace, or route usually points to GPS rather than the workout engine. The Galaxy Watch Ultra uses dual-frequency GPS across the L1 and L5 bands for distance and route tracking, but it can only do that job if it has permission and time to acquire a signal.
When you start a workout, Samsung Health asks you to allow any permissions, including location. If your distance and route keep coming up empty, make sure you accepted the location permission when prompted. Then, before you begin moving, give the watch a moment outdoors to acquire GPS, since starting indoors or immediately can leave the early part of your route unrecorded.
Bring the Watch Software Up to Date
Outdated firmware can break step, heart-rate, and workout tracking, so an update is one of the highest-value fixes once the basics check out. The Galaxy Watch Ultra now runs One UI 8 Watch, which is based on Wear OS 6, so staying current genuinely matters.
You will need at least 30% charge before you start. To update from the watch, press the Home button (Power button), then go to Settings, then General, then Watch software update. To update from your phone instead, open the Galaxy Wearable app, go to Watch settings, then Watch software update, and tap Download and install.
Restart the Watch to Clear a Tracking Glitch
When tracking has simply stopped working for no obvious reason, a normal restart often clears the temporary glitch without touching any of your data. This is the gentlest reset there is.
Swipe down from the top of the watch screen and tap Power. Tap Power again to turn the watch off, then turn it back on and try starting a workout again.
Force a Restart If the Watch Is Frozen
If the screen is frozen or the sensors are completely unresponsive and a normal restart is not possible, you can force the watch to reboot. Getting this exact button sequence right matters, so follow it closely.
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 (some models show "Rebooting..."), then release both buttons. Note that the Home button may also be labeled as the Power button.
Back Up, Then Re-Pair the Watch to Your Phone
If tracking still fails after a restart and an update, the connection between the watch and phone may be the weak link, and re-establishing it can help. This step can erase data, so back up first and do not skip that part.
Start by backing up from the phone. Open Galaxy Wearable, then Watch settings, then Accounts and backup, then Back up data. Then, on the watch, swipe down from the top and go to Settings, then General, then Transfer watch to new phone (shown as "Connect to new phone" on some models) and select the checkmark, then open Galaxy Wearable on the phone and tap Start.
Be aware of Samsung's warning here. Depending on the Galaxy Watch model and software version, reconnecting to a new phone may reset the watch and remove all existing data. That is exactly why the backup comes first.
Factory Reset, Then Contact Samsung for a Sensor Fault
As your last software step, a factory reset clears any deeper configuration problem that the earlier fixes could not. Make sure you have backed up your data, because this erases the watch.
To reset from the watch, go to Settings, then General, then Reset, review the information, and tap Reset. To reset from the phone instead, open Galaxy Wearable, then Watch settings, then General, then Reset and confirm. The app-based reset is preferred, because if you reset from the watch itself, some watch data may still remain saved on your mobile device.
If step, heart-rate, or workout tracking still does not work after a factory reset, the cause may be a hardware sensor issue rather than software. At that point Samsung advises visiting a Samsung service center or scheduling a repair through Samsung Support, where the sensor can be properly checked.
Frequently Asked Questions
Why does my Galaxy Watch Ultra miss short workouts?
Automatic workout detection only begins after about 10 minutes of continuous activity, so brief sessions are easy for it to miss. To make sure every session is recorded, start it manually in Samsung Health by tapping Work out, choosing your activity, and letting the countdown finish.
My distance and route are missing even though the workout was logged, what is wrong?
That is usually a GPS or permission problem rather than a tracking failure. Confirm you accepted the location permission when Samsung Health prompted you, and give the watch a moment outdoors to acquire a GPS signal across its L1 and L5 bands before you start moving.
The watch is logging exercise when I am just driving, how do I stop that?
Open Samsung Health on the watch, tap Settings, then Workout detection (also shown as "Activities to detect"), and turn detection off using the same switch you would use to turn it on. You can also fine-tune which activities the watch looks for under Activities to detect.
Do I need to update my watch for better workout tracking?
Yes, outdated firmware can break step, heart-rate, and workout tracking. With at least 30% charge, update via Settings, then General, then Watch software update on the watch, or through Galaxy Wearable, then Watch settings, then Watch software update on the phone.
I tried everything and tracking still fails, what now?
Back up your data, then perform a factory reset from Galaxy Wearable, then Watch settings, then General, then Reset, which is the preferred reset method. If tracking still does not work afterward, a hardware sensor fault may be the cause, and Samsung advises visiting a service center or scheduling a repair through Samsung Support.
