I've been trying to figure out why my internal phone storage keeps getting so low. When I install apps, I move them to the SD card whenever possible, but it doesn't seem to help. I have removed apps installed on the SD card and have seen the internal phone storage go up. If they are on the SD card, why does it affect internal storage? Also, I found a file browser app, and I found a folder called "cache" in my phone that had apks in it of apps I had downloaded. I deleted the files, but I did not see the internal storage in my phone go up. I found another folder that had apks for apps that came with the phone. I did not delete those, but would it hurt anything or even matter if I did? So where is Android looking when it reports the available space? What's hogging all the space? Phone is a Sanyo Zio on Sprint running 2.2.
