I haven’t had a Samsung phone since Android Gingerbread, but I do have a Samsung TV in my guests room and every time it gets turned on, my pi-hole blocks a lot of traffic under the ads and tracking category, so Samsung’s phones are probably similar.
I think their screens are really good and they also have 5 generations of foldable devices, more than any other company.
Still, I wouldn’t buy one because I don’t like their software and they tend to restrict functionality unless you use other Samsung devices. For instance, a Samsung Galaxy watch, even running Wear OS, will not have all the features enabled unless you pair it with a Samsung phone.
I’m so used to Android that when I try to use a friend’s iPhone it just doesn’t seem intuitive to me. But to be fair the same happens with heavily modified versions of Android, like MIUI.
I think iPhones are mostly ok, but I can’t stand the fact that something so expensive feels so laggy because of the 60Hz refresh rates.
They have pretty damn good face recognition though, but at the price of a gigantic pill/notch on the screen.
