Let’s just see what 13.2 brings. It’s literally just days away now. I have the 11 pro max so I don’t have concerns about iOS 13 and even if I did the max came with 13 anyway lol. But I do have a 7 plus as a back up device and that one is still on 12.4.1. And since it is just a back up there’s no need for it to be on 13 yet. It’s nice having full 3d touch functionality on it. Who knows, on that one I may never update it and a year or so from now I can brag about it like those that bragged about iOS 10.3.3
