Oneplus One

Here is a device that rivals the HTC One M8 and the Samsung Galaxy S5 for raw specs, but at a cost of just £229, $299 (around AU$320). That's less than half the price of those aforementioned big hitters. It's primarily made up of a quality matte plastic shell that extends around the back and sides of the device. This isn't a unibody construction, and this rear panel can be removed for customisation purposes, but it's firmly fixed in place with minimal creaking or flexing.

There's a metal-effect plastic rim that separates this rear cover from the glass front, which cheapens the effect ever-so-slightly, but it's thin and unadorned. It does mean that the aforementioned glass frontage appears to stand out rather than melding into the body of the phone, but it's not an unpleasant effect.
 The 5.5-inch, full-HD display, which has a resolution of 1,920x1,080 pixels, is bright and vibrant and is usable even under bright sunlight at noon.

The OnePlus One runs modders' favorite CyanogenMod 11S, which is based on Android KitKat 4.4. It's very similar to stock Android, but with a few modifications. These include an expanded desktop mode, and the ability to use gestures to turn on the camera or the LED light when the display is turned off. Other interesting tweaks include a voice-activated wake-up, and themes that let you really customise how the UI looks.

The OnePlus One comes with its own camera app, and it has a range of modes that can be easily activated by just swiping down or up on the screen.The 13-megapixel shooter uses a Sony Exmor IMX 214 sensor. The shutter is really fast, but image quality is average at best.
