Running out of precious “internal” memory on a Samsung phone? This may help slightly: the Samsung code to get to “Delete dumpstate/logcat” is
What does “Delete dumpstate/logcat” do? It does what it says, it deletes dumpstates (coredumps from software crashes I assume), and deletes logs (informational/error event logs), both of which are not much use to the typical android user. I probably wouldn’t mess around with anything else in there though.
The first time I used it it freed up a nice chunk of system storage. Doesn’t do much at all now when I run it.
