Sorry, it's the other way around...and the number of pixels these days is virtually meaningless.
The amount of pixels in a camera became meaningless years ago for all but professional photographers who need the image blown up to massive sizes.
Not to get too long winded and boring (yeah, right, have you ever seen my posts

) But let's take an example.
Choose a size for your printed photo, let's say a nice big 8 x 10 print. Multiply the width by 300, and the height by 300, which gives you the size you need in pixels. (On average 300ppi is what you'll use for a good quality print.)
So, an 8 x 10 print works out to 2,400 x 3,000 pixels. To get the total amount of pixels in the image multiply the width by the height. So when all is said and done that 8 x 10 inch print will contain 7.2 million pixels.
So there's your answer, normal consumers don't need any more than 8 million pixels in a camera. Too much more than that and the manufacturers are just playing the numbers game to lure people in.
In fact if you consider that most of the photos end up on places like Facebook or twitter, you're not going to need a camera with more than 1 million megapixels for that kind of stuff.
Far, far more important when it comes to cameras are the size of the sensor, the size of the pixels and so on and so on. Not the ridiculous amount of pixels some manufacturers cram in.
As for anything else with the iPhone 7, yeah they've just used a revised design. It's still an attractive phone compared to the majority of the competition. The hardware however is phenomenal. The A10 is a thoroughly impressive piece of work, the potential of which hasn't even begun to be tapped.
The screen isn't OLED, it is however the very best LCD ever to grace a phone. When was the last time you looked at your iPhone and decreed the image to be unbearable, I don't see anything wrong with the iPhone screens myself.
They've improved the sound and finally added stereo. They've finally made it water and dust resistant. The cameras are actually reLly good, especially on the 7 Plus. I spent days pouring over images from the iPhone 6/6s and Plus, 7/7+, Note 7, S7/Edge and others. I had no intention of upgrading this year, but the camera on the 7 Plus won me over.
I've seen a lot of grumbling about the cameras on forums and in reviews. I've seen reviews where they declared the cameras to be much the same as the 6s, despite that they seemed to have forgotten they had already said they were viewing them on their laptop. Yeah, that screen isn't going to show some of the improvements you div.
People are always going to have their preferences, they aren't going to be the same as everyone else's and that's good. But I spent a good bit of time comparing the iPhone 7 to the competition. Other than the frame they come in a lots similar but the iPhone, in my opinion wins out in a couple of key areas. The performance and the camera and as I don't care if the screens OLED or not and I especially don't want a completely unnecessarily high resolution screen in a tiny device. My choice is the iPhone 7 +.
I'm not devoted to Apple. I've had Samsung, HTC, LG, Nokia and Sony phones. So as far as I'm concerned it's an open field and I'll choose the one I deem to be the best. I don't care about reviews or what other people think and really, neither should anyone else.
