To check the firmware, turn off the bar. When off hold the settings button until the words start scrolling across the screen. The current firmware will scroll across the screen.
With smartthings everything should update at the same time. It doesn’t always work out that way. If you update by USB, you have a couple extra steps to update sub and rears. To do this turn on the q90r and let it sit for a minute or 2 then tap the volume button then press and hold the down button on the circular pad until update flashes across the bar. Update should flash on the screen for a few minutes, and then it’ll cycle through turning off and restarting a few times. Let it be for a minute or two to make sure it’s done with updating
Good reference thread
Good morning friends. I've performed the firmware update for my HW-Q90R soundbar. Given that there is no official statement from Samsung with the details of the update I would like to check with the community what new features have been included. - How can I check now the firmware version...
