WATCH BEFORE YOU BUY HK4 HERO 

HK5 HERO

Hi. You can go to your smartphone Bluetooth settings and touch on forget divice. Than pair it again. The Bluetooth on watch will go off automatically after some minutes and suppose to turn on by itself when you recieve a call or when you go to the music player.

Many thanks is there a Bluetooth settings on the watch itself I’ve tried this only connects for a few seconds then disconnects

@Trig672 Hi. No. It turns on and off by itself, but it doesn't has to manually turn on/off

Right

Please solution fix call connect
