My Z7+ has a problem almost as long as I can remember. Every so often like every few days the box comes unresponsive to any inputs from the Remote control.
The only way to fix it is to unplug the power from the back and plug it back in. Then the box reboots and it will be ok for a few days until the next time.
I find this rather annoying. I have owned the box for a couple of years now so it has had a few updates over that time but it continues with the problem.
Is anyone else having this problem? Is there any fix for it?
