Over the past two weeks of usage, I performed usual tasks of surfing Internet, played a few apps games, played music through apps. I hardly added any new apps (no more than 20 MB each) during this period. All these, however, have costed me in excess of 500MB in disk storage. Now the bell is ringing, asking me to delete some photos and videos as the disk is running at zero capacity. Why has this happened? Who has consumed my disk storage? I tried deleting some apps and thus released some storage. But that didn't last too long before the disk warning pops up on the screen again. Soon I'll have all my apps deleted, and you bet the disk storage problem is still there. Any opinions?
