Hi all, ok this is a thing that’s been bugging me for a long time.
Finally i’ve found the way to fix it without root permissions, sweet, i’ve been able to free almost 600mb :O
This will bring up the Sysdump
Hit the ‘Delete dumpstate/logcat‘ button. Hit OK on the confirmation dialog.
Scroll to the end of the screen and hit ‘Exit’
All i have to say is: FINALLY!
