I upgraded from 14PM to 15PM. I actually love the phone. People will hate me, but I’m a case free user. Ever since then I love how the phone feels. It’s pretty quick too. Especially, with Siri. Moreover the cameras look the same yet there’s some speed boost here and there. Portraits are much faster now. Raw doesn’t take much more time to process than before. I haven’t tried log yet I love the action button.
