I hate the volume slider for the Q990B (not sure if it's like this for all their soundbars). It's more difficult than it needs to be when setting volume levels. Samsung, if you're listening, please fix this!!!
They have updated the app to do either. Make sure your tv and phone have the latest firmware. You k ow can also use the volume rocker on your mobile for tv volume. Click remote options then adjust and slide to let or right on bottom
