For the best camera and video results, use a high-quality memory card with a speed rating of class
10 or higher.
A slower memory card may not record video quickly enough.
If you are viewing videos on your smartphone using a wireless connection to the camera, try viewing them in another location with less wireless interference, or try transferring videos to the smartphone.
Transfer important recordings to a computer or smartphone, and format the memory card.
If the device displays a memory card error alert, first try formatting the memory card and then, if necessary, replace the memory card.
