I have a 9930 with an 8gb memory card. I was having some trouble with it so moved all of my pictures and videos to my pc. It gave me about another G of memory but still said my memory is 57% full with "other" being the cause of it. 2 hours later and im down another .5 in my memory card memory. I don't understand what can be using up so much memory. I cleared my whatsapp logs. downloads.... I have few apps installed. Any advice?
