Lorepie, Jun 14, 2019 : I have the One Plus 3 and I've never had a problem with it. Since updating to the 9 Pie suddenly the smile detection from the camera has disappeared. Does anyone know how to get this feature back? There is nothing in the settings that say "smile detection" or "smile capture". In fact the settings for the camera are quite disappointing. The smile capture was a great feature. Any help appreciated.
