I know that it's going to be different for everyone but I've always had around 90-110mb of free space available. Maybe a week ago I noticed I had 72mb of free space and today it's down to 65mb. I have not installed any new apps so I'm wondering, what's eating up all the space? I also have not been putting loads of "mirrored" apk files in the /system/app folder, actually to the contrary.
So what's eating up my space? How do I determine what it is and what's normal?
