Then either try to take a photo or create a file in your internal memory, or reboot and test your internal memory.
Edit: Just to be clear, the default user/owner for Sony internal memory is 2800, mine is set to 1023 (media_rw), as most phones should have, because I have modded the ramdisk in my kernel in order to use a certain program.
Working with Xperia V and just fixed my sd card. Thnx
