I am looking for a little device storage help. I cook my own roms but have noticed a heavy decrease in device memory as of late. the last two roms i have built are only showing 74.68 of total device memory with 53.47 in use memory leaving me with only 21.22 left over. I have not added any additional cabs, that is all cooked in items. Is there something I can do to free up space or is this just because im using the Rhodium 2.1 manila? Thanks.
