I can't tell what I could've done to cause this, but for some reason, the volume buttons on my phone only change the audio/video volume, not ringer. Any way to find out what is causing that or any way to fix it?
if you have SBSettings uou can go to more/mobile substrate addons and turn off all tweaks, see if that helps, if it is fixed, turn on 1by1 to find the exact problem tweak.
