I have a Samsung Replenish (low end phone) on Sprint, running standard non-rooted 2.3.6 Plain and simply, I added up all the internal storage space that my programs use, and it comes out to 95.56 megabytes Snapshot_20120729_4 | Flickr - Photo Sharing! As you can see on my flickr though, my phone cleary comes up with "142mb used, 19mb free". That leaves about 47 mb's unaccounted for. After some googling around, I read that sometimes install files can get left on the systems internal storage, and without a rooted phone the only way to truly delete them would be to perform a factory reset. I've already done some of the traditional space-saving measures. I've deleted all my unwanted apps, cleared cache, and have everything possible moved to the SD card. I don't want to root my phone, and I don't want to perform another factory reset. Are there any other options here?
