In my Apps settings, there are two different sections, one called "Internal Storage" with a total of 6.07GB of space, and one called "Phone Storage" with 9.93GB of space. What's the difference between these two? I assume the Phone Storage is the same as the advertised 16GB of storage for my particular phone (EVO 4G LTE)? Why does there need to be two separate areas, rather than one large storage space? Which of these two is the default for app downloads? Thanks. P.S. I'm considering getting the S4. Will it have this same division of space, or does it only have the 16GB (which is more like 9GB, like my current phone) for everything?
