So the past few weeks has been my first experience with safe strap and everything.I have been using only the Hyperdrive rom. After having some issues with the RS14 update, i had to delete the rom slot and make a new one. Ive noticed that i have a ton of hidden files, because i have almost no space left on the internal storage. anybody have any ideas on how to find and delete these files? I would also like to know what you guys set the slot as, as far as given space. this is the only rom im going to be using so i want to maximize my space.
