The Nokia Lumia 800 won “Editor’s Choice” award of 2011 What Mobile magazine. Their review rated it 5/5, and said “The Lumia 800 is a massive step forward for Nokia and sits apart in an increasingly crowded market. Alongside Windows Phone Mango, there’s enough inside the Lumia 800 to worry rivals and make iPhone fans jealous”.Brian Klug of AnandTech in his review wrote, “The Lumia 800 is indubitably the best Windows Phone hardware out there right now” , with notable features such as “camera without compromises, hardware build quality that’s unique and solid, Nokia’s attention to detail…” Regarding the shortcomings, Klug wrote, “lack of USB or external storage, a still fledgling application ecosystem, and a few others.” Regarding the Camera, Brian Klug said, “Lumia 800’s camera comes out looking very good against the rest of the 8MP competition, and for me this is the first F/2.2 8 MP shooter I’ve come across. With less compression and better ISP, it could be even better than most.” In the Engadget review, Sharif Sakr wrote, “Nokia’s Lumia 800 is a sophisticated and capable smartphone that melds its hardware beautifully with the Windows Phone OS.” Sherif Sakr writes that while the phone lacked features like USB mass storage, expandable storage, the phone is a welcome for those who want to be “part of a carefully crafted, simple and generally happy emerging ecosystem.” PC World said that the Nokia Lumia 800 has solid guts and shiny looks, and was an “interesting proposal”, though they also said it had “nothing extraordinary to offer” when compared to the highest end models the Samsung Galaxy Nexus, Motorola Droid RAZR or the more expensive iPhone 4s in hardware and software. Cnet UK noted that the phone was ‘overall, the Lumia 800 is a very good handset. The Windows Phone software is slick and fun to use, especially if you like to keep up-to-date with what friends are up to on social networking sites. It also looks attractive and the excellent build quality gives you the confidence that it’s built to last. CNET UK made a camera comparison with the current high-end phones iPhone 4S and Samsung Galaxy S II and wrote that Lumia 800 “didn’t offer the quality of camera we were hoping for.” Regarding the Camera, GSM Arena wrote that, “We were quite impressed by the job done by the 8 megapixel sensor and the bright F/2.2 lens. Images might not be the sharpest around and the noise levels are only average, but their colors and contrast are great, despite the sub-optimal lighting. Cameraphone lovers should definitely check this one out.” Ketaki Bhojnagarwala in The Hindu review wrote, “The Lumia 800 isn’t perfect, but its one of the best products that Nokia has released in the market in recent months. I have no complaints about the hardware - Nokia gets it right every time. Windows Mango is a refreshing and vibrant operating system that’s already got a big fan list,…”

Matthew Baxter-Reynolds of The Guardian, after using a Nokia Lumia 800 for a month and being a previous iPhone user, argued that the Nokia Lumia 800 is not up to an iPhone. In summary, he wrote: “I really wanted Windows Phone to work for me. This was £400 of my own money spent to try it. But it just doesn’t work well enough to be the small-scale personal computer that I must have on me all the time.” Sales have allegedly disappointed some UK operators as they have been just barely superior to the basic Nokia “Touch and Type” phone, and not even close to the iPhone or high-end Android phones.
