[citation]"If you're saving photos, videos or music, where does it go? Is it on your phone? Or on your card? [/citation]
Of course, I will save photos, videos on the card. It is easier to manage the data stored on the card. I don't need to restore the data after the reset or changing the phone.
Also, tit is more likely and easier to of retrieving the data if the phone is crushed or broken when the data is stored on the card.
If I buy the card with large capacity e.g. 32GB and it's not expensive nowaday, I hardly need to take the card out.
