The iPhone 7 plus (have no experience with the 7) is a beast. I'm coming from the note 7, previously galaxy s 6 (since my time with the note 7 was cut short). I felt very skeptical making the move to an iPhone, seeing as the specs seem somewhat lacking for its price, in comparison to many android devices. This device, however, turned out to be a beast. It is on par with the note 7, even surpasses it on some levels. Sure, screen isn't as beautiful (though I'd argue, it looks more natural and realistic), but despite that it's definitely one of the best phones out there.
As for the complaints, always remember that people who are happy with their device won't be posting about it on any forums. They'll be too busy enjoying their device. That's not to say that there aren't gonna be some faulty devices in the first, perhaps even rushed, batch of devices.
As for the yellow tint, I only notice that when I change around on my settings (battery saving mode and night shift mode), otherwise it's a really great looking screen. The colors look beautiful on it
Not sure what people expected from this phone. I find it a very exciting phone with many new and improved features.
Though, I do miss my wireless fast charging from my Samsung devices. With this battery life, however, I can definitely live without it.
