I have put an earlier review about the connectivity of the watch with my oneplus 7 device. I was not able to connect it at the time I got this. However I tried it again by clicking the icon on the top right corner of the app front menu and by using the option "Add a new device". This time it got connected and everything is working perfectly. I don't know if it will continue to do so. But as of now it's great. I controlled Spotify with it and it was all good. Watch Model: GBA- 400

I have an earlier, review of 1 star. But Im giving them 4 stars now. I already pair my new watch on my new phone. You only need to clear the previous pairing your have on the watch. I like the update because you can now control your music on third party music apps. Not unlike before that you need to have GMIX musip player app & have your songs downloaded. Just one more request, please make it more easier to adjust the time on the watch using the phone. Or to have it sync with phone. Thanks
