A while ago after transfering some files to/from my PC via USB mass storage mode I unplugged the USB cable without doing a Safe Disconnect on the PC. Immediately after this, the processor (or something in the lower right corner) on my Droid 3 started overheating and draining the battery very quickly, as if I was running some very pretentious 3D game or something.
I found some discussions on the Net that lead me to look under Settings / Applications / Battery use to find that an application called "Media" was overusing the processor and causing the overheating and drainage, so I force-stopped that one and the problem went away.
But now every time I connect the phone to a PC in USB mass storage mode, I get the same problem and after I'm done transfering files I have to force-stop the "Media" application. (This is even if I use Safe Disconnect or whatever it's called on the PC.)
I've seen some other suggestion today that I should try the same operations with the SD card pulled out, but the same thing happens even in the absence of the SD card.
Does someone know how I can reset/reinstall the "Media" application or server that handles USB mass storage mode without resetting the whole thing to factory settings or reinstalling the whole Minimoto image?
