I'm a Galaxybuds user ...
I am aware of how to turn the volume up or down using the touch control on the buds.
I have noticed something recently..
When I'm using the two buds .. it's fine ..
If I Take one off and back to the charging case .. the other ones (that is still I'm my ear) its volume goes down a lot ..
It's still on max volume.
But the sound is way way down .. are my Galaxybuds faulty ?
i am using galaxy buds and i don't have your problem. check that your bus's software is up to date. if you still have the problem. then i think it is a technical issue.. you can contact your dealer and replace it under the warranty coverage
