So a lot of us are a month in with the phone - would be interesting to hear some fuller follow-up comments. For me, I'm very happy with the phone. Much more than my prior S7 Edge and Note 5.
- The design has made my S7 Edge feel outdated. I played around with it a couple days ago and the bezels, physical home button - all honestly felt low tech. It's amazing how quickly you move on but I do much prefer the haptic feedback I get for the S8+ home button (after setting it to the most sensitive and for hard press to bring up home).
- The extra screen for the phone size is a constant plus for what I do most - browsing, reading, FB, etc. I have everything set to the most condensed + extra condensed via developer settings which improves the amount of content per screen.
- Battery life is amazingly good for me. Days which would kill my S7 Edge by the afternoon get me to the end of the day with plenty in reserve (30-50%).
- The phone has remained fluid and more responsive than prior Samsung phones. However it's only been a month so I'm keeping an eye on this.
- I haven't really noticed any false touches due to the curves which is considerably improved over the S7 Edge
- Camera seems about the same as my S7 Edge which is good. A little less artificial at night which is a plus though my wife's iPhone 7 still makes more pleasing low light photos, albeit much darker.
2 cons really:
- I've learned to live with the fingerprint scanner as I really only need to use it for Samsung Pass. However if I didn't have a Gear S3 which let's me use Samsung Pay and keeps the phone unlocked when I'm nearby, this would likely be a bigger annoyance. I use two hands now which is not actually unusual considering the size of the S8+, but this is IMO the one improvement the Note 8 can bring with an embedded fingerprint scanner.
- Glass screen protectors are usable but continue to either creak or provide rainbow areas. I *know* you shouldn't have to use one, but I'm super anal about screens. If I get a scratch I can see, it would make me sell it and buy a new one.
I love it. I upgraded from a 6P and prefer the S8 in nearly every way. The only thing better on the 6P is the location of the fingerprint sensor, but I've gotten used to the S8 enough to get by and it's not as bad as I thought it would be.
The thin case that I'm using doesn't affect the size of the phone much, which makes it feel fantastic. My very first case was a typical rubber w/ plastic shell hybrid and it was boring in comparison. More protected, but ultimately boring. The thin case I have on now makes a huge difference in usability. I will say that if I used a thin case on any of my other phones it also would probably have been an improvement, but the design of the S8 really shines.
Apart from the few days of battery issues I've had which seem like something is wrong (outliers basically) the battery life is solid. Not only is it good, it's good without having to disable a bunch of features like I used to do. I leave everything on push, my weather app is up to date with my location, bluetooth stays on for the most part for my Garmin band, and I'm still in much better shape than my previous device.
Plus, and I know there's a lot of people who will scoff at such a claim, but modern day Samsung gives a better experience than the vanilla Android you get from a Nexus. You can argue that the only reason it's this smooth is because of brute force... that phones are fast enough to keep up with the bloat, but whatever the reason may be it still works.
There is nothing I need to root for at this point, as it's already covered by either Android or Samsung. This is a big deal, as there were still a couple things I wanted to root for on the 6P which caused problems with Android Pay, but now I use Samsung Pay and it works great. Just used it yesterday and I liked it. The way it's integrated into the phone so I can pull it up anywhere is also nice.
As you mentioned, the only thing holding it off from being perfect is how it will hold up over time. How will the battery life fair, and clunky will things be two years down the road? I'm pretty optimistic though.
