Anybody know the best way to really, I mean REALLY deep clean out the SD Card/Internal Memory of the XTZ? I've been running low on space for a while now, and no amount of SD Maid/Cleaner etc seems to help. I've gone through and deleted everything I can, but frankly I only really see 1-2gb of files, another 1-2gb of TB backups, and then <1 gb of miscellanous app data and what not. Nowhere close to the 16gb, even giving a little leeway for system/os size.
I therefore figure it has to be the internal memory/android secure -- something like that. Can anyone give me a good idea of how I might totally release all that storage?
Alternately, if anybody knows a way to TRULY zero out the XTZ -- rom/software wise -- I'd be willing to completely rebuild my setup from the ground up, just to get a bit more breathing room.
Thanks very much for any assistance/ideas, I really do appreciate it.
