I have a Lenovo S5 with 64gb internal storage. I had this problem for a while now, so i really need some help.
Any file manager that I can find sums up all my files and aplications at under 20 gb, however i only have 3 gb free.
About 40 gb are filled with invisible/unfindable files. I looked online for answers many time, and I tried using "Android terminal emulator" with the command "df -h" and got this result, can anyone make something of it?
