[Huawei P9 Plus Questions & Answers] tsaojam:
I'm currently using both of these phones (as well as an iphone 6s plus), and there are definitely pros and cons for both. Now overall I'm primarily using the P9 plus, and the reason is that I travel quite a bit so the dual sim function is extremely useful. The problem with the S7 edge is that even the dual sim models only have 32GB, so it's not enough memory. If the S7edge had a 64G dual sim version, it would probably edge out the P9 plus, but only ever so slightly. Let me list some of the pros and cons:

- battery life: The S7 edge has slightly better battery life (my version is the exynos version), but the P9 is very good too, it's just that the S7 edge is excellent. So for me it depends on your usage pattern. With both sims activated, the P9 plus lasts me just through a full day, so having the S7 edge's battery life would be better for me in terms of peace of mind.

- memory: as mentioned the P9 plus comes with 64G so it's the much better choice here if you are not adding a memory card.

- screen: I actually prefer the P9 Plus because it's flat. The S7 edge's edge does get annoying at times and the viewable area feels more comfortable on the P9 plus. Quality is very similar.

-fingerprint sensor: P9 plus. You don't need to press on it and the activation is quicker than the S7. The S7 isn't bad, but it's a step behind the P9 plus and the iphone 6s plus as well. I'm fine with the placement of the button, both locations work well and it's easy to get used to.

- software: P9 plus. The latest touchwiz is ok, but I always slap on Nova, and so overall I actually find the Huawei software to be leaner and quicker. It's one of the fastest Android phones I've used in day-to-day situations. Not sure what type of memory the phone uses, but my P9 plus flies. The Kirin processor is inferior to the exynos but in normal usage I actually feel that the operation feels smoother on the P9 plus. Now I don't play games so I'm sure there's a difference there, but in terms of using apps like instagram, flightradar, google apps, browser, etc. it's at least a tie. I think Huawei's built in battery power manager is also more robust than the Samsung one. When you restrict background processes Huawei really shuts it down. I don't use Samsung's split screen much so for me the lack of it is no big deal. One annoyance of the Huawei though is that I can't figure out how to make notifications display properly in the notification bar. What I mean is for my weather app, it normally can display the weather on the notification strip at the top. On my Huawei, it shows an icon that depicts the app running but not the actual weather information. I can't seem to find a way around this.

- camera: tie. The S7 edge is slightly faster, better in low light, and has sharper details. I however prefer the P9 plus' color rendering and overall picture before zooming in. It's probably because of the lack of ois or something, but when zooming in for example to words on small objects the S7 does a much better job of rendering this. But at the end of the day who's reading the text on small objects? So this one is a tough call. I love the P9 plus' camera effects and overall picture quality, but you've got to be more steady handed in low light. I also love the S7 edge's ability to quickly take a picture and knowing that more likely than not the picture will be quite good. Just to add I basically don't shoot in raw format.

- I haven't rooted my P9 plus, but I have rooted my S7 edge. I don't it's much of an issue as both can be rooted. Haven't had any major issues with either software and they seem to be updated at the same pace.

- build: tie. The P9 plus feels super premium in my opinion, and the S7 edge is a looker. It comes down to whether you like the metal look / feel or the glass look / feel. Having said that you pretty much must have a case for the S7 edge or it's too difficult to hold without accidentally hitting the screen's edge.

- music through headphones: this is actually pretty important for me, and both of these are above average performers. More treble and less bass than the iphone 6s plus in my opinion, but very clean output. So no problems for either on here. I keep Huawei's own music enhance off though - I find that adds way too much bass and distorts the actual quality of the music.

These two phones are definitely the two best Android phones I've ever used, and I've used a lot (I actually also have a G5 but it's purely a music player now...it really cannot compare to either one of these other than the camera). Other than the memory / dual sim issue, I think it purely comes down to:

1. do you play games? the Samsung chip may be better for this

2. How heavy a user are you? the Samsung battery may give you the extra juice needed

3. Screen / typing: the edge screen can definitely be a pain when it comes to typing, which could be the tie breaker that goes in favor of the P9 plus

I guess overall, the Samsung slightly edges the Huawei. If the price similar and you don't need dual sim and the curved screen doesn't bother you, I'd go with the S7 edge. But again the P9 plus is a great phone in its own right.
