Uhd55 tv, voice command when pressed says, we're having trouble connecting, make sure your online or try later.
Firmware up to date
signed in to samsung and internet connection fine. ???
Mke sure your microphone hole on the remote isn't blocked. Make sure you have fresh batteries. Unplug your tv and then plug it in to get a fresh reboot. Other than that, I don't know what else you can do except to get a new remote control.
