I own a galaxy s2 plus rooted on android 4.2.2 jelly bean
My problem is I have a memory issue and when I looked to which app or folder took the most space I found out that the total used space (by sum each app or file size) was only 1.5 gb while the system shows 3.4 of used space !!!!
I really want a solution for that problem cause I need much space
Ps. I am also looking for a way to move app with all of irs data to the external sd card if someone provides that it will be very helpful
