I bought a secondhand S4 the other day. It all seems to work fine, wifi, 3g, texts, calls - but the internal storage, which originally came up as mostly empty in the settings (as you'd expect), after downloading a few apps becomes totally full. Like, can't stream a video cos you don't have the space full. The settings screen shows it as having negative free space.
I've got a 32GB SD card coming so it'll be okay, but what gives? Where has all the space gone to?
Thanks for reading
