I'm thinking (just THINKING) of updating to 4.4, but after reading here and talking to a really knowledgeable CSR at AT&T, I'm having my doubts. She suggested backing photos and music to the SD card and removing it before the download, then clear the cache and/or factory reset after (contacts are backed up on Google, and I don't have that many apps). But..how do I figure out how big the music and photo are? I have an 8GB card in there now, with nothing on it, but I can't figure out how to tell how big my music and photo files are. Any way to do this?
