Not sure if I have the same problem, but sometimes my lg g watch r freezes and the screen is unresponsive, yet the hands are still moving. I am able to get Google assistant up by holding the side button but that is it. I get it working again by leaving it for a while and restarting by holding the side button for 8 seconds, but, then again, it may be a different problem. I'm pretty sure this happens because the processor gets overloaded as it is an older watch.
