You can hold your device either vertically or horizontally, so if one isn’t picking up, try rotating your device. You can also try from different angles.
Hold your device so the entire photo, including the colored bar at the bottom, is visible. Make sure to leave some space around the photo.
If it’s too dark where you’re at, we may not be able to detect the photo. Turn on a light and make sure you’re not casting a shadow on the photo.
