Nokia Lumia 2520 is a Windows RT tablet developed by Nokia. The Lumia 2520 is Nokia's first Windows-based tablet, and the company's first tablet since its former Nokia Internet Tablet line. Sharing its design with the Lumia series of Windows Phone products, the device incorporates a quad-core Snapdragon 800 chip with LTE support, along with a 10.1-inch 1080p display and an optional keyboard dock adding additional battery capacity, ports, and a keyboard. Following a period of speculation and leaks, the Lumia 2520 was officially unveiled on October 22, 2013, and released in the United States about a month later on November 21, 2013.
The 2520 was met with mostly positive reviews, praising its design, display, and for being the first Windows RT tablet to offer cellular data. However, the device also received criticism for the lack of available software for its operating system, along with the design of its keyboard dock.
Development and release
In mid-August 2013, details began leaking surrounding a Windows RT tablet being produced by Nokia codenamed "Sirius", which featured a 10.1-inch screen, LTE support and a design similar to Nokia's Lumia series of Windows Phone devices. A press render leaked in October 2013, along with its branding as the "Lumia 2520". The Lumia 2520 was officially unveiled during a Nokia press event on October 22, 2013 at a Nokia Workd event in Abu Dhabi, where it also unveiled several other Lumia phablets running Windows Phone 8. The device marks Nokia's first Microsoft Windows-based tablet device, and its first tablet product since its Internet Tablet range.
The Lumia 2520 was first released in the United States by Verizon Wireless on November 21, 2013. In the U.S., carrier-branded versions were released by Verizon and AT&T. The Verizon Wireless model differs only in its use of different LTE bands, and a lack of support for GSM networks, unlike the international and AT&T version. No Wi-Fi-only version of the Lumia 2520 was released.
In April 2014, Nokia recalled the AC-300 travel charger for the Lumia 2520 after it was discovered that the cover on its plug could separate and expose internal parts, posing an electric shock hazard when in use. While sold as an accessory in the United States, it was bundled with European models; as a result, Nokia also suspended sales of the Lumia 2520 in Austria, Denmark, Finland, Germany, Russia, and Switzerland, and the United Kingdom.
The Lumia 2520 uses a quad-core, 2.2 GHz Qualcomm Snapdragon 800 system-on-chip with 2 GB of RAM and support for LTE networks, and has either 32 or 64 GB of internal storage which can be expanded up to 64 GB with a MicroSD card. Its display is a 10.1-inch, 1080p IPS panel with Nokia's "ClearBlack" technology, coated with Corning Gorilla Glass 2. The Lumia 2520 also includes an 8000 mAh battery rated for 10 hours of use, a 6.7-megapixel rear-facing camera identical to that of the Lumia 720, micro HDMI and USB 3.0 ports, and a proprietary dock connector. The Lumia 2520's hardware design uses a similar polycarbonate-based style to Nokia's line of Lumia smartphones, available in either red, cyan, black, or white finishes. An optional keyboard dock accessory known as the "Power Keyboard" adds a keyboard, kickstand, two full-sized USB ports and an supplemental battery, rated for 5 hours of additional use.
The Lumia 2520 ships with the Windows RT 8.1 operating system. It can run apps obtained from Windows Store only and is pre-loaded with Microsoft Office RT and a suite of Nokia-provided apps, including a customized camera app, Here Maps, Nokia Music, Storyteller, and Video Director.
The Lumia 2520 was released to positive reviews; early reviews praised the tablet for its display and design, and praised its performance for showing a notable improvement over early Windows RT devices such as the Surface RT.
Engadget gave the Lumia 2520 a 79 out of 100, considering it to be a "strong" entry into the Windows tablet market, but criticizing the limitations of Windows RT and the poor Windows Store app selection, the fact that there was no Wi-Fi-only model, the keyboard dock's key layout being too "cramped", and the dock's kickstand was criticized for echoing the design of the original Microsoft Surface, which was poor for "in-lap" use because it only had one angle. However, the Lumia 2520 was praised for having a light build, and a relatively better camera than other tablets (but criticizing the quality of its video recording, describing it as an afterthought). The battery life of the device was noted for being even longer than Nokia claimed, reaching 13 and a half hours of video playback with Wi-Fi enabled and the display on 50% brightness. The Verge believed that the Lumia 2520 had better performance than the Microsoft Surface 2, and was more "portable" due to its LTE support (which the entire Surface line lacks), but criticized the keyboard dock for being too heavy, and shared concerns surrounding the application selection for Windows Store.
