Good again to all,
after time without writing anything here, today I bring you a solution to something that's been me "giving the can" since Android Roms deal with, especially with CyanogenMod. The problem is that once installed rom of Android, especially in S2, a note or two, so good, but when time passes, they begin to space problems arise.
At first I thought it was a problem of the Dalvik cache, but since probing more, I've realized that the problem is .... log files.
To solve this problem, the solution is simple, use a file manager that allows us to manipulate the internal memory of the device in question (Astro, Root Explorer or similar) and enter the folder / data / log and delete the files you have inside. You will see how significantly increases the available space of your device :)
Greetings!
