You definitely have to give it two weeks, esp the first time you switch from iOS to Samsung. It feels foreign and frustrating at first but you quickly find all the things you can do with Android that are not possible with iOS. I've gone back and forth once (first to Note 8, back to XR, then to Note 10+). When I went back to iOS, I missed many little subtle software features with Android and felt frustrated by the static icons, esp navigating b/w apps. I missed the back button, app switcher, and being able to run two apps simultaneously (you will love Google Map navigation which runs in a small window inside whatever you're doing, also being able to respond to messages in small popup). Dismissing notifications and closing apps is so efficient. I also love the way it tracks battery usage and notifies me if an app is burning battery. The AOD is awesome and I can arrange my home screen however I want it.
I'm not someone who uses more than one phone or wants to be constantly switching and trying out new phones although I enjoy reading about others' adventures here. My Note 10+ has been everything and more I want a smartphone to be and I am totally satisfied with it. I like Apple products and still use an iPad Pro for media consumption but after switching over from Mac to a Surface Pro and from iPhone to Samsung, I can say I am glad to feel freed from the walled garden. I wouldn't say I will never return to an iPhone and Mac combo but they are going to have to make their hardware more competitive and affordable before I do so. I hope you enjoy your new phones. Please give yourself more than a couple of days to truly understand and enjoy the new operating system. It truly takes a couple of weeks.
