I recently purchased a vivo active 5 and the last couple of weeks it keeps disconnecting from my phone for no apparent reason, I have had to reset the watch to factory settings, removed the app from my phone disconnected the Bluetooth etc etc and again today it's disconnected itself again. This is extremely frustrating because I lost yesterday's readings and have done so in the past too if it continues I will have to take the watch back it's a shame because it's a good bit of kit when it works but at the moment it's not working most of the time! I would expect more considering I paid over two hundred pounds for it in fact the very basic Fitbit had better connectivity and that cost less than fifty pounds.
