I have a VA4S that has consistently been having phone connection problems in the 2 months I've owned it. I keeps dropping the bluetooth connection. I have tried a factory reset and repair, turning off/on bluetooth on the phone and watch, turning off/on the phone and watch, and turning off bluetooth on the phone and watch, turning off the phone and watch, waiting, turning on the phone and watch, and then turning phone and watch bluetooth back on.
Does anyone have something else I can try or something that worked for you?
