you can NOT access the internal storage asigned for the apps, that's why you see certain internal memory but thats for pictures, music, videos, not for the apps

Xperia M has not Phone storage and all apps are installed in Internal storage. This volume is limited to 2GB which is insufficient to installing big files and games.
