Announced in October, the Oppo N1 isn't your typical smartphone. For one, it's huge -- the 5.9-inch full-HD display takes up most of the space, and it comes with something you seldom see in a smartphone: a rotating 13-megapixel camera that you can flip over to take a selfie.
Design
Packing the aforementioned large display, the Oppo N1's shape reminds me of the Samsung Galaxy Nexus, though the handset lacks its slightly curved display, thanks to its curved edges. And while the N1 looks like it has an edge-to-edge display like the LG G2, it's actually not the case, as you can see in our picture below.
Screenwise, I have no complaints about the 5.9-inch full-HD IPS screen of the N1. Colors were vivid and there were no color shift issues even when using the phone at awkward angles (which you normally won't). The only concern I have is that the large size of the handset doesn't really fit into your pocket all that well at times. (I had to take it out of the front pocket of my jeans when sitting down or it feels really uncomfortable.)
Features
The Oppo N1 uses a custom operating system called Color OS that's based on Android 4.2 (Jelly Bean). Interestingly, the UI looks very similar to Xiaomi's MIUI, especially the buttons and fonts. Color OS generally handles very much like your standard Android smartphone, and there are some software tweaks such as an image enhancer that adds makeup to your selfies, as well as a theme app (like MIUI) that lets you reskin the OS to your liking.
There's also a gesture feature that's activated by swiping down from the top-left corner much in the way that you would bring down the drop-down notification menu. You can then quickly use your thumb to draw a pattern that can be set to do a whole array of things, like launching the camera, a flashlight, or an app. I found that simple gestures are the easiest to do; make it too complicated and you'll have issues trying to repeat it.
