The Microsoft Lumia 950 XL is a large and powerful smartphone powered by the Windows 10 Phone OS. It stands out with its 5.7-inch, OLED display packing 1440 by 2560 pixels. Inside it ticks Qualcomm's octa-core Snapdragon 810 SoC which has been liquid-cooled to facilitate heat dissipation. And the camera is one worth being excited about – a 20MP sensor with OIS and a tripple LED flash is found at the back. The latter uses three LEDs to produce more natural colors. Further specs include 32GB of on-board storage, a microSD card slot, a 3440mAh battery that can last through 19h of talk time. The USB Type-C port at the bottom is a welcome bonus.

The Microsoft Lumia 640 features a 5-inch HD display, comes in a range of vivid colors, and runs on Windows Phone 8.1 (it's set to get upgraded to Windows 10 in the not too distant future). The Lumia 640 has all the options you'd expect from an affordable phone: more specifically, it arrives in a single- and dual-SIM versions with both a 3G model and 4G LTE version of the handset, including a dual-SIM LTE device. The handset comes in a range of colors including cyan, orange, black and white. It's also got an 8-megapixel camera with dynamic flash and auto HDR, as well as a front-facing camera with wide-angle lens. It is pre-loaded with the latest Lumia camera app update.

Nokia Lumia 920 is the first Windows Phone 8 flagship of the manufacturer with a modern dual-core processor, and the first with an HD screen. After all, this is what the competing mobile ecosystems have been offering in their flagships for a while now, so Nokia finally had to offer something to go spec-for-spec against the Android monstrosities, now that Microsoft caught up. Before we go into the things that set it apart from the competition, let's recap the specifications - we get a huge 4.5" screen with 1280x768 pixels of resolution, a 1.5GHz dual-core Snapdragon S4 chipset with LTE radio to boot, 1GB of RAM, 32GB of internal memory plus 7GB of SkyDrive cloud storage, and an 8MP camera on the back with ceramic zirconium camera detailing. The screen tech is called PureMotion HD+, meaning blur-free scrolling on the curved glass display. Nokia calls it the "fastest LCD display", with up to 2.5 times faster refresh rate and new supersensitive touch technology, that allows you to use it with gloves. A new ClearBlack technology iteration is in the Lumia 920, and it adapts to the outside brightness to minimize reflectance. ClearBlack is proven to give the best smartphone visibility outside in direct sunlight, so the screen should be a looker. Pixel density on the new display is 332ppi, a record in its class, and it also sports a high-brightness mode of 600 nits.

Nokia X Dual SIM smartphone was launched in February 2014. The phone comes with a 4.00-inch touchscreen display with a resolution of 480 pixels by 800 pixels at a PPI of 233 pixels per inch. The Nokia X Dual SIM is powered by 1GHz dual-core Qualcomm Snapdragon S4 Play processor and it comes with 512MB of RAM. The phone packs 4GB of internal storage that can be expanded up to 32GB via a microSD card. As far as the cameras are concerned, the Nokia X Dual SIM packs a 3-megapixel primary camera on the rear.

The Microsoft Lumia 535 doesn’t offer high-end specs, but it’s certainly a step up from the slightly older Lumia 530. Powered by a quad-core 1.2 GHz Snapdragon 200 processor, the phone features a 5-inch IPS display with 540 x 960 pixels, HSDPA, Wi-Fi 802.11 b/g/n, Bluetooth 4.0, 1 GB of RAM, 8 GB of expandable internal memory, and a 1905 mAh battery. On the back, the Lumia 535 has a 5 MP camera with LED flash, while its front-facing shooter is the same 5 MP one that we can find on the selfie-centric Lumia 730 / 735

The Lumia 532 sports a 4" 480x800 resolution display with 233ppi pixel density, 5-megapixel camera and 8GB of storage (expandable via a microSD card). The devices is powered by a 1.2 GHz quad-core Qualcomm Snapdragon 200 processor paired with 1GB of RAM.

Given its entry-level status, one shouldn't expect anything noteworthy in the specs sheet of this Lumia newcomer. Powered by a dual-core Snapdragon 200 chipset ticking at up to 1.2GHz, which works in concert with 1 gigabyte of RAM, the Lumia 435 is positioned on the lower end of the smartphone table. It has a 4" LCD display with a resolution of 480 x 800 pixels, a 2MP main camera with fixed focus, VGA selfie-shooter, 8GB of native storage, a microSD card slot, and last but not least, a 1,560mAh battery to keep the lights on.
