Here is a nicely done video comparison between IPhone 7 Plus and Note 7 that also manages to sum up in general the difference between the two platforms when choosing between other phones by Apple and Samsung. While the reviewer rightly calls some attention to the S-pen functionality that I do indeed use and value, higher end Samsung phones that lack the S Pen do still offer a solid experience.
People do complain about lag and lack of updates on Samsung. I can't comment on that personally as I have not experienced any of that. I've gotten updates for my individual apps as well as security upgrades from AT&T. I very carefully manage and curate apps so that may be a factor in my not experiencing lag. I don't know. I'm going to need more time with Samsung to evaluate that fairly. I've had years with Apple and only a few months with Samsung so far.
I do agree with Saki in his video that apps and games are done better for IPhone in general. It's not an issue that bites me in the butt often but I have seen examples. My daughter and I played the same hidden objects game, New York Mysteries: Lantern of Souls and she played the iPad version and I played one for Android. I had a problem with some of the puzzles not responding to touch input until I rebooted the game. My husband's financial services apps work with Touch ID on IPhone but not on the Note 7. There was an app developer on Mac Rumors who posted a long post somewhere explaining why this happens. In a nutshell, it is a royal pain in the butt writing apps for Android vs iOS.
Still, I manage to find apps that work well and do what I need them to do without any fuss or bother.
