I moved all my Xbox games to my SD card (14gb worth), and it says my phone storage is being used by mostly apps and games. It never went down after moving my games. Any help? Thanks!
Should we assume by "latest build" you mean Windows 10 Mobile build 10586.11?
You may want to try a soft reset, or even just a "power cycle" where you power down and back on. Afterward, go back to the storage and check it again. It should refresh the data after a soft reset. There are times that there is a delay in getting that data refreshed in this build.
