The Snapdragon 855 processor and 8GB (or 12GB with certain variants) of RAM guarantee there’s a lot of power under the cover here. I question you will discover any performance problems early on. It is a super smooth experience, and all that fluidity senses much better because the software has some developments, as well.
The new “One UI” running on Android 9.0 Pie had currently thrown out to the S9 and Note 9, however it is here out of the box. Some of the improvements are delicate, but several make a change over time. For example, larger icons, better settings layouts, and menus make it simpler to find things. Swiping and navigating with gestures felt softer to me, even from when I first examined on those prior Samsung handsets.
Reality is, there is a lot in there. This is one reason why I had wished Samsung would improve its settings app. You can still look for whatever you like, but it is not a bad idea to take some time to look through. For example, one neat feature that is away by default is Dual audio, where the phone can simultaneously stream to two Bluetooth headphones or speakers. One more is Smart pop-up view under Advanced characteristics, which sends notifications as icons you can preview.
Then there is the Bixby button on the left edge. Lastly, Samsung is allowing users reassign it. At one point, I set it to open Google Maps or Google Assistant, while a double-click would trigger Bixby. Just note that Bixby has to be one of them; you can not ignore it totally when assigning the button.
Approximately I loved the display, I wish it was not so sensitive on the sides. I caught myself accidentally selecting things as I was picking it up or laying it down. The Edge Panel interface is still there, but you can turn it off completely, which I did after a while. Ironically, as simple as it was to accidentally tap something, as I explained, I did not find accessing the edge menu as user-friendly.
That’s the point about good hardware and software, though. It’s easier to nitpick at the things that are slightly irritating, however eventually take small away from the experience. Samsung has long stated the ability to customize the user experience on their phones, but I have never been fully persuaded. The One UI is a big step in the right direction.
