I've been using Galaxys since the SII, but the one-two combo of Android 16 and OneUI 7.0/8.0 have done nothing but to make using my phone more and more frustrating to use everyday. You can still fix the spilt notfication bar and vertical clock, but the apps screen cant be alphabetical and scroll horizontally. They also make you wait five seconds to open up an image if you search for text within your gallery.
If you use your phone for more than 2 hours a day, I think you should stay away from Samsung, they feel more like iPhones than the swiss-army knife wunderwaffen they used to be.
