jefboyardee: In Settings>Manage Apps, did you look in Running?
I tried starting it, then going to task manager to switch to the running app, System Settings. Ringer Volume does not show up in system settings. It does not even show up in MIUI's task manager.
sherri: Almost sounds as if you somehow changed the function of the "search" button, as it is only raising and lowering volume....
No, I didn't (although I did attempt to remap the search button a few hours ago. But this is after discovering "Ringer Volume" on my search button). The search button does not raise or lower the volume. All it does is show a list of (mostly) search apps, a couple of dialers, and then this ringer volume app. Selecting Ringer VOlume in the list brings up a volume control panel.
RyanB: Well, you could take the nuclear option and do a factory reset followed by restoring your apps one at a time to find the culprit
That is NOT an option at this point! To make a long story short, I have gone through too many trials of having to rebuild my system from scratch, the last couple of weeks. I have close to 300 apps installed now, so I don't have any more time for that!
lunatic59: No, I'm not sure it's an app; especially as Root Explorer could not find it by name. It could be a shortcut created by an app (although I don't see which app it could have come from). However, I AM sure that it's not a "recent search criteria showing up in the search bar". It's not showing up in a search bar. It's showing up in the selection menu that pops up when you hit the search button (and you have more than one search app installed).
