Storage space running out. Some system functions may not work

In my Android in notification bar I see message Storage space running out. Some system functions may not work.

When I check I see 188 MB free in device memory and around 10 GB in USB storage.

I re-installed Android OS a few times.

It helps for about a couple of months then the problem returns.

If I delete some applications or data it helps for a few hours to a few days.

Questions:

• Why do I get Storage space error if there is a lot of available space?


• Can I join device and and USB memory? Will it help or at least delay the time while the problem return?



• Any other advice how I can deal with this problem?

Answer

On Samsung phones, type in the dialer *#9900# then choose the second option: "Delete Dumpstate/logcat".
