Hello. Ever since the latest Update on my Galaxy S6 Edge (to Marshmallow 6.0) the ringer/notification volume will randomly revert from silent to 'on'. Typically this occurs when I am listening to media through my headphones and a call either comes through, is made, or rejected. Following either of these events, the volume changes from silent to active. There have been other times when the volume changes randomly and not dependent on any specific occurrence. This is extremely disruptive at work! Anyone else having a similar issue?
