I'm not tech savvy so maybe I'm just doing something dumb (good chance, even), but my internal storage has suddenly been very crappy recently. I have 2GB of internal storage (awful, I know) and it says my storage is full. However my phone says I only have 155 MB of crap in internal storage. Whenever I uninstall yet another app, I still can't download anything, even the same app again. Advice?
