I have never been part of the beta programs and just stuck to the regular public iOS releases. I have my phone updated to the newest 10.2.1 and whenever I use portrait mode with Depth of Field, the background is not blurred and the subject is blotchy and looks like it was taken with an old flip-phone camera. I reset my iPhone and found when i tried the camera mode again, it asked me to try the public beta of iOS 10.2.1... I'm confused, is there not a finished product of the portrait mode or is my phone just having issues? Thanks for any assistance/feedback. I have the iPhone 7 plus on iOS 10.2.1 Kallum.
