My son had an issue today where we were calling his GizmoWatch 2 and it would ring loudly - but he couldn't answer the call. When he got home, we tried it out and sure enough if my wife or I called him, it would ring loudly, but the date/time would appear on the screen and there was no way to answer a call.
The only way I was able to fix the issue was to power down the watch, then turn it back on. After that, when I would call, our images would appear and he could answer the call.
How do I prevent this from occurring in future? Are software bugs like this reported to ZTE or Verizon?
