Mattias_ASUSI am using MEGABOOM 3. When using phone's volume control it does control volume but only that phone outputs. When using MEGABOOM's volume control ot does not controls phone's output volume.
Which Bluetooth device are you using? I have tried several headsets, speakers, and headphones, and I can't recreate the issue.
Mattias_ASUSI have tried it. Only permission I am asked for is contacts and history.
Thanks for the reply @vasilnvalchev
I was checking around and this has happened to some other devices too, is the speaker software updated to the last firmware?
Something else that can happen is that when the speaker is connected for the first time, your phone can eventually ask you for permissions, some of those permissions are to allow control of certain features such as the volume adjustment.
My tip here would be to delete the speaker from your device and re-connect it and allow the features.
