I went from a Samsung Galaxy Note IV to an iPhone XR. I was very worried about the change. But honestly the experience with the iPhone has been so much better. I don't have the phone dying all the time. Gone are the software hangups and crashes. I don't even remember the last time I had a frozen screen that required a phone reboot - an all too common occurrence with the iPhone.
But the NUMBER 1 best thing about the iPhone is the Lightning jack port. I HATED teh stupid mini-HDMI of the Samsung. The stupid mini-HDMI connector would get loose and lose communication/charging ability after a few months. I went through so many new mini-HDMI cords. With the Lightning jack of the iPhone, I get a solid connection EVERY single time. I bought one 10 foot cable for the iPhone when I first got it, and the connection is still like NEW.
