3. After that, open the WearOS app and try to connect your device.

FIX 3: Using Wear OS by Google (China) App

1. To begin with, uninstall the Wear OS and Galaxy Wearable apps from your device.
2. Then download and install the Wear OS by Google (China) app on your device.
3. Now launch the app and grant it the location permission [if it doesn’t ask, then manually grant it via the Settings menu].
4. After that, tap on the overflow icon situated at the top right and select Show all devices when pairing.
5. Your watch will now appear in the list, select it. At this point, some users have reported that while the app is stuck in the pairing process, the watch actually gets paired [but not connected]. You could verify the same from the device’s Bluetooth screen.

7. The  Galaxy Wearable app will reinstall the Watch 4 plugin and with that, your watch is now successfully paired and connected with your device.

FIX 4: Pair Once with the Device having Watch’s Firmware

Your last course of action could be to pair your watch at least once to the device that has the same firmware as your watch. For example, if your watch is of a Chinese variant, then you will have to pair it once with a device that is running the Chinese CHC/CNC firmware. Once that is done, you may then be able to pair your watch with the device of any region without any issues.

However, it is no easy task to find a device having the same firmware as that of your watch. But if you are ready to dig a little deep into the technical jargon, then you could change your device’s CSC to the one that your watch has, then flash the watch’s region firmware on your device and finally pair your watch. Once your watch has been paired, you may then revert to the original CSC on your device and pair your watch again, and from now on you wouldn’t face any issues.

That’s it. These were the four different methods to fix the ‘This watch isn’t supported on this phone’ error with the Galaxy Watch 4. If you have any queries concerning the aforementioned steps, do let us know in the comments. We will get back to you with a solution at the earliest.
