Sorry for the late reply.
I'm assuming that the internal storage is the storage that the phone originally has?
Well the thing is the phone I'm guessing, comes with a lot of preinstalled apps that I can't seem to uninstall. And so now I can't update any of the apps that I have downloaded myself. also when I click on storage, it shows the "calculating ... for all the other stuff like pictures music and downloads. but only the apps comes up. And Like I mentioned I literally only installed 6 apps. I have never DLed any music and such other then the stuff that are on the sd card.
Also I get an error when I try to update that the "application cannot be installed in the default install location"
