I have created a simple app for changing master volume. This app would be helpful for those who do not wish to use physical keys. This app works in dev unlocked device and greater.
Finally, thanks to Fiinix for the dllImport project.
Few improvements imho:
*mute button should unmute if phone allready muted
*max level button
*arround 3 custom buttons (that you can previously set the vol level to w/e you want)
*a metro icon
Yes, all dev unlocked dev...
Thanks for the finding.. I removed the default value 17..
Plz use the attached XAP.
Added custom buttons as you guys wished.
I tried to change icon. But I am very poor in design. Please feel free to change the icon and post.
