The camera supports 1080p video capture and is complemented by an LED flash and a two-stage shutter button. The front camera has a 0.9 MP sensor with a wide-angle f/2.4 lens, and supports 720p video recording.
Connectivity
The Lumia 830 supports 4GLTE technology with maximum transfer speeds of 150 Mbit/s. Other wireless connectivity options include dual-band Wi-Fi802.11a/b/g/n, Wi-Fi hotspot, NFC, Bluetooth 4.0, and wireless screen projection via Miracast.

The Lumia 830 includes a variety of sensors, including proximity sensor, ambient light sensor, magnetometer, gyroscope and accelerometer, as well as Microsoft's Motion Dataactivity tracker based on Qualcomm's SensorCore technology.[7] Due to chipset limitations, however, it does not support passive voice activation for the Cortana digital assistant.[8]
The Lumia 830 supports video recording in Dolby Digital Plus and captures 5.1 surround sound from its dedicated microphones.
The handset is also capable of decoding 5.1 Dolby Digital content and playing it back through virtual surround. For stereo content, the mobile can convert it into virtual 5.1 using the Dolby Digital Plus feature for audio playback through HRTF.
The new Lumia Camera app in the Denim firmware update adds support for Rich Capture (HDR imaging), DNG capture and Moment Capture (high-quality 2 MP stills extraction from 1080p video).[9][10][11]
The Lumia 830 has received mixed to positive reviews. Most critics commended the design, build quality and camera performance, as well as the availability of several high-end features at a mid-range price. On the other hand, many reviewers found fault with the chipset performance, display resolution and the overall Windows Phone app ecosystem (as compared to Android and iOS). Several reviews drew attention to the fact that the Lumia 830 would be the last Nokia-branded smartphone, with future models carrying the Microsoft Mobile brand instead.
Engadget gave the Lumia 830 a rating of 80/100, calling the rear camera "impressive" and praising the premium design and solid battery life, while criticising performance in graphics-intensive games and gaps in the app ecosystem, particularly for Google's services. Editor Philip Palermo concluded the review writing: "... in general, life was rather pleasant with the 830. It's an Icon(ic) phone that cuts most of the right corners."[13]
Lee Bell of The Inquirer described the Lumia 830 as offering many of the same features as the higher-end Lumia 930 while being more compact, commended the availability of multiple colours and called the display "the most impressive we've seen on a Nokia Lumia device".[14] A later review by Alastair Stevenson praised the impressive camera, as well as the enterprise and productivity features, while criticising the performance of Internet Explorer and the lack of "many apps that certain users will rely on for personal use".[15]
Brett Howse of AnandTech called the Lumia 830 "one of the best Nokia phones launched [in 2014]", praising the design and ergonomics, but finding that the performance does not measure up to the "affordable flagship" moniker. The review concluded with: "The combination of the metal band, a thin chassis, a light weight, a decent display, and a decent camera make for a phone that is very good for the right price", but also noted that the phone costs more than it should in many regions.[16]
Ivan Petkov of GSMArena.com highlighted the phone's design and build quality as positives, and found no major problems with performance, saying that the operating system runs "buttery smooth, without any lags whatsoever". New features added in Windows Phone 8.1 Update 1 and the Lumia Denim firmware update were also praised, while the main downside was seen to be the availability of mid-range Android phones that offer comparable or better specifications for the same or lower price.[17]
Andy Vandervell of Trusted Reviews gave the Lumia 830 a score of 8/10, saying it compares favourably to the higher-end Lumia 930 in terms of design, and praising the camera's low-light capabilities. Poor performance in certain games was once again pointed out as a weakness, and the phone was said to be "useless as an in-car sat nav" due to the placement of the buttons and Micro-USB connector.[18]
Nic Healey of CNET gave the phone a favourable review, listing the camera, design and overall value as positives and saying that "the Lumia 830 does its dynasty proud". The main criticisms were against the 720p display and the appeal, or lack thereof, of the Windows Phone ecosystem.[19]
Business Insider UK ranked the Lumia 830 as 15th in their best smartphones list.[20]
