Alot of people are saying that 16gb is plenty of storage and we have no need to store apps on sd. I find a them to be wrong in several instances. For me, I have games such as gta vice city, nova 3, dead trigger, modern combat 4, and many more games. Nova 3 after initial install and downloaded files takes over 2.5 gb of space. After everything is installed on the knternal memory we have about 11gb to play with. I am constantly trying to make room for the next big game. I bought a 64gb micro sd for this reason. I know there are ways to fix it through root but I really dont feel like running that route if I don't have to.
