If there is a memory card in your phone, and your phone memory is filling up, save the photos you take and videos you record to the memory card.
Before recording videos to the memory card, make sure you use a fast enough microSD card, that is, class 4 or higher. For full HD (1080p) videos, use at least a class 6 card.
