Dear ASUS, please find resources to realize "motion photos" in next camera software updates. It works already on some Gcam ported versions, so hardware is not a reason "why we can't". Thank You!
We used to have this feature long time ago but decided to remove it since too few users actually used it. There are tons of apps that can do this kind of looping photos/videos with better features and functionality. https://binge.co/what-are-the-best-loop-video-apps-for-android
