Currently on my android device there is a bell icon used to signify volume when I used the rocker on the side of the phone which seems odd to me. Whenever it appears I feel like I'm looking at my Alarm or something.
I know googles logic is that this is Notification Volume (under which they lump ring tones, message tones and app notifications) but I was wondering if there were other examples of this being used over something more conventional like a little speaker with some sound waves? What are the other common iconography selections for sound on mobile?
If I use the volume rocker on the side of my phone I get this:
I do however get the volume option when videos or music plays so I see what they're getting at.
When I use the volume rocker I personally would prefer to adjust all the sounds emitted by my device rather than various divisions of it and access the divisions under settings. I'm sure it makes sense to lots of people but it confuses me regularly. What are some other default volume divisions when using the rocker on other mobile devices?
