I've searched and tried several apps to link ringer and notification. I love TouchWiz, but this is the ONE thing that pushes me to a CM ROM. I don't want to have to open an app each time i want to change both options. I came from an Optimus V and a Thunderbolt after. Both were able to link Ringer/Notification volumes.
My Samsung Galaxy S 5 allows the ringer and notification volumes to be different. Despite this, Llama is complaining that Android 4.0+ does not allow different volumes, and is giving me the options to "Use volumes anyway", "Moan to Google", or "Make volumes the same".
