Below are my initial impressions of the purported “Nexus-killer.” For a full list of specs features, check out our earlier coverage here.

ghter— thinner—than other phones

The minute I picked up the Oneus One, I really like what I saw: a thin, polycarbonate chassis; a vibrant, almost edge-to-edge high-resolution display; a fluid, customizable interface. It’s a beautiful device, though it slightly resembles a flattened-out version of the -manufactured Nexus 5. And while the Oneus One was surprisingly light to hold—at least compared to some of the latest flagship hsets I’ve been wielding—it was still a bit wide. Regardless, I can see the phone picking up traction with users just for its thinness alone. The Oneus One adopts the same hardware button convention as other stock Android phones: a power button on the right a volume rocker on the left. The capacitive navigational buttons are also fully customizable from the Settings menu. You can even define specific behaviors for gestures like a double-tap on the screen or a short press of the menu button.

’Customize everything’

Cyanogen’s ethos is that you should be able to customize everything, this proves out, emphatically, with the Oneus One. It runs a custom version of CyanogenMod 11 tweaked to run optimally on the One’s hardware, features some very extensive theming capabilities. By default, the One model we used had three available themes, including the Android default Holo theme Cyanogen’s OneMod. The custom icon packs looked a lot like ones we’ve seen crop up before in the ay store, the idea of being able to simply flip a switch to use them sounds much more enticing than having to dig for them elsewhere. Cyanogen said it planned for deeper integration than just icon packs, so each theme comes packed with different boot animations, fonts, icon, wallpapers, lock screens, ringtones. As an added bonus, you can mix match parts of the different themes as you see fit.

A camera for the masses

Cyanogen intended to deliver a camera interface that’s easy for anyone to use one-hed. It’s debatable whether the Oneus One sticks to that original promise, as the phone is so large. But I digress. The camera interface is simple minimalist, just like stock Android’s, except that it doesn’t require you to do that annoying “swipe-up–up–away” motion to adjust camera settings. It also does live facial recognition, which worked remarkably well even in the preview. There’s also live filter support, which was also really impressive. I like the idea of seeing what my final, filtered shot will look like before I even snap a photo.  Cyanogen Oneus don’t seem too concerned about getting the masses to jump ship to their tweaked Android hset, that’s too bad. The customization options are easy to use, would appeal to even the most novice smartphone users. Oneus would do well to up-sell its themeing capabilities to the less technological savvy, while also touting hardware spec more granular software customization options for the hardcore Android-loving masses. ’ll do a thorough review of the hset put it through its paces once it becomes available. Stay tuned.
