My Vivo smart 4 watch won't connect to my android phone anymore. It worked for couple of months before the problem occurred with Garmin server being hacked. So I uninstalled the app from my phone. Once all good I reinstalled Garmin app and tried to pair but it won't pair nor show in Bluetooth options. I tired another phone to pair but same issue. Seems like the phones can't discover the watch. I tired all recommend methods to resolve this issue but no joy. Only worked for couple of months before it's broke.. does anyone know if it's still in warranty or can be fixed by me? I've tried Garmin site methods.
