My phone is using 7.62 gb & only has 8 gb total. It is from factory installed apps updating. I already deleted and moved everything possible. I gotta delete my cashed data everyday just to access my pics. I even did a factory reset not long ago & it just filled back up with updates. I dont even have any downloaded apps or games. Guess thats the phone companies way of getting you to buy a new phone. Just another legal scam!!
