Sorry folks I'm v new to Drones
Took some photo's last night and didn't have my SD card inserted.
I've got the v low resolution cache images on my mobile but I'm sure the last time I made the same error the chache images were better quality.
Any ideas?

cache image is always low resolution,  you should try in SD card

Hi, thanks for the inquiry. Like Zubayer mentioned, the cache file in the mobile device is mediocre. If you would like to get the full resolution of the photos or videos that were captured by the drone, it's recommended to use the SD card. Thank you for your support.
