To connect a Galaxy Watch to a Samsung Galaxy phone, turn on Bluetooth on both devices, open Samsung’s Galaxy Wearable app on the phone, select the watch it finds, and follow the pairing and permission prompts. The exact steps and available features depend on the watch generation, phone software and region.
Before pairing, check that your watch and phone are compatible
Galaxy Watch compatibility is model-specific. Samsung Singapore’s compatibility table, last updated September 5, 2026, lists these minimums for the named Wear OS watch families. Each entry requires at least 1.5 GB of phone RAM; meeting the threshold does not guarantee that every feature will work.

| Watch family | Minimum Android version and RAM | iOS |
|---|---|---|
| Galaxy Watch9 series and Watch Ultra2 | Android 13.0; 1.5 GB RAM | Not supported |
| Galaxy Watch8 series and Watch Ultra | Android 12.0; 1.5 GB RAM | Not supported |
| Galaxy Watch7 series and Watch Ultra | Android 11.0; 1.5 GB RAM | Not supported |
| Galaxy Watch6 series | Android 10.0; 1.5 GB RAM | Not supported |
| Galaxy Watch5 series | Android 8.0; 1.5 GB RAM | Not supported |
| Galaxy Watch4 series | Android 6.0; 1.5 GB RAM | Not supported |
These are Samsung’s published thresholds for the listed models, not a guarantee of universal compatibility. Samsung says tablets are unsupported for these pairings and that certain non-Samsung phones may not work. Features, menus and settings can vary by model and software. For the exact phone and watch combination, check Samsung’s Singapore connection and compatibility guidance.

Samsung’s Canada guidance says select earlier watches, including Galaxy Watch, Watch Active, Watch Active2 and Watch3, can connect to iPhone using older Samsung apps, but some features and services are unavailable. That guidance applies to devices sold in Canada; it says Watch4 and later Wear OS models do not support iOS. Samsung also notes that certain older Gear models work with Galaxy S25 only on Android 4.3–13, not Android 14 or later.

- Prepare both devices. Turn on the watch and enable Bluetooth on the phone. Keep them close together.
- Open Galaxy Wearable. Install Samsung’s Galaxy Wearable app from a trusted app store if it is not already on the phone.
- Start setup and select the watch. In Galaxy Wearable, tap Start or Continue, allow it to search, then select your watch when it appears.
- Confirm the pairing prompts. Verify the prompts on the phone and watch, grant requested permissions, and follow the remaining on-screen instructions until setup completes.
- Choose what to enable. After pairing, use Galaxy Wearable to configure watch settings and select which phone apps can send notifications.
Samsung’s detailed Galaxy S25 setup instructions cover the S25 with Watch Ultra, Watch7 or Fit3. Screens and labels can differ on other combinations; use the relevant model’s Samsung support page if the app’s steps do not match.
What sync does after pairing
Sync is a group of functions managed through different apps and settings, not one universal switch. Samsung documents the following examples for Galaxy S25 paired with Watch7, Watch Ultra or Fit3; other models may differ.

- Notifications: Choose permitted apps in Galaxy Wearable. Depending on settings, some phone notifications appear on the watch while the phone screen is off or locked. Samsung’s S25 guide also describes syncing Do Not Disturb on supported models.
- Health data: Daily health data from the named watches syncs to Samsung Health on the connected phone. In Samsung Health, Sync with Samsung Cloud enables continuous cloud syncing; this does not establish that every metric syncs for every watch or account.
- Music and photos: For Watch7 and Watch Ultra, Galaxy Wearable’s Manage content controls support automatic music syncing and syncing selected photo albums. Samsung says these transfers are not available on Fit3.
- Calls and messages: When connected to a Galaxy phone, calls and messages can work over Bluetooth. An LTE watch with active network service can use its mobile connection instead. The same messaging app must be configured on both devices.
- Modes: Samsung’s guide shows modes such as Sleep syncing between the phone and supported watch.
Some Samsung Health Monitor functions have separate requirements: Samsung’s S25 guidance specifies a Galaxy phone running Android 11.0 or later, at least 2 GB RAM, and Samsung Health Monitor version 6.22 or later from Galaxy Store. This is a requirement for certain health functions, not for ordinary watch pairing. Samsung states that heart-rate software functions are not intended to diagnose, cure, mitigate, treat or prevent disease.
Troubleshoot a Galaxy Watch that will not connect
- Check Bluetooth on both devices. Make sure Bluetooth is enabled on the phone and watch.
- Bring them close together. Samsung gives a maximum Bluetooth range of 10 m (32 ft), but says actual range varies by environment. For pairing, place the devices beside one another and remove obstacles.
- Check Galaxy Wearable. Confirm the app is installed and updated, reopen it, and scan for the watch again.
- Review Google Play services permissions. On the phone, open Settings > Apps > Google Play services > Permissions. Check the categories under Not allowed and allow the permissions needed for connection.
- Restart both devices. Restart the phone and watch, then open Galaxy Wearable and try again.
- Recheck model and software compatibility. Verify the exact watch model, Android version and any regional requirements before trying more disruptive steps.
Samsung’s connection troubleshooting page recommends these checks. Do not factory-reset as an early troubleshooting step: a reset can remove watch data, and transfer behavior depends on model and software.

Move an existing watch to a replacement Samsung phone
Back up the watch before starting. In Galaxy Wearable, open Watch settings > Accounts and backup > Back up data. Samsung warns that reconnecting to a new phone may reset the watch and remove existing data, depending on watch model and software.
- On a supported watch, open Settings > General > Transfer watch to new phone.
- Confirm the check mark on the watch.
- On the new phone, open Galaxy Wearable, tap Start, and select the watch.
- Confirm that the number displayed on the phone matches the number on the watch, then continue through the agreements and setup prompts.
- Wait for setup to finish. If a backup is available, Samsung says a restore option may appear during setup.
Menu labels and transfer behavior can vary. Samsung’s new-phone transfer instructions were updated April 14, 2026; follow the steps shown on your particular watch and phone.
