Check the settings on your g watch, make sure you don't have anything turned off like notifications first. If you still have troubles just report back here & I'll do my best to help
YEP, like cedellh, said. I Had to call LG Wireless Support and explain my watch wasn't working and there was no OS version. I sent it back in for repair, and got a NEW one weeks later. I was able to update it to the latest Lollipop version.
