You cannot use the standard Google Play App. You must go through the Wear App from Samsung. If you open the Wear App the bottom will have Store. Use that. Have not had a problem installing Apps from there. Not all apps will have a Watch app associated with it.
@rugby49 there are multiple ways to get apps:
- You can use the Google Play Store.
- You can use the Galaxy Wearable app and click on Store.
- You can swipe up on the face of the GW4 and click on the Play Store icon.
@rugby49 "Only the ones from Wear store from Wear app have been checked by Samsung to work with the Wear OS."
Do you have a reference for this information?
Going to the Plays Store from the GW4 certainly only lists things compatible with the GW4.
Since the ones listed in the Play Store are filtered by your device, you will only be able to download to the GW4 the ones compatible with the GW4.
