There is a folder on my phone called "0" that is taking over 5 GB of internal storage, I don't think its the ROM because have a 16gb phone and total space is 10.12 GB so I presume its the android system/rom is making it 10gb instead of 16. The weird thing is though is there's a file inside 0 that says android and has a load of app files and stuff in it. I would really appreciate help, and that 5 GB would be very useful. Thanks.
