Our 3D face scan app requires the use of Apple's front-facing True Depth camera in order to create an accurate, good-looking action figure. Not all iPhone models have this camera, and sometimes when they do, this camera can malfunction even if the front-facing selfie camera is still working.
Be sure that you are using an iOS device with FaceID technology (iPhone X and higher, and iPad Pro 4th gen and higher). Also check that you have the latest iOS software update on your mobile device. Currently, we support iOS 14+.
