I've got the weirdest issue with my #Android 4.2.2 device. Every time I restart it, a bit more of the internal storage is taken up by ... something, and now it's full. I've set my 16GB external SDcard as the "default write disk", and changed the settings on all my apps so they write to sd1 (I presume the internal storage would be sd0). The external SD is almost empty. What am I doing wrong?
