Nokia Lumia 820 - Solid Windows Phone 8 Mobile

1/25/2013 6:05:58 PM

Nokia Windows Phone 8 possesses strong configuration, nice, sensitive touch screen and has many interesting features but usually have fault, namely the reset of the software.

Lumia 820 is one of the impressive smartphones at the end of 2012. In comparison with previous version of Nokia smartphone, Lumia 820 is equipped with high sensitive touch screen which allows users to wear gloves or use pointed metal things to drag, pinch and drop directly on the screen.

The phone is innovated in shooting function and has exclusive function from Finland mobile company such as positioning navigation on map without internet connection or “virtual reality” allows users to specify position and destination by scanning camera around.

As compared with Lumia 920, the 820 version has some different points of design such as: not having the monolithic design, the removable plastic cover allowing the users to change the SIM, memory card or change battery easily. The phone doesn’t have Pureview function, which helps to take nice photos in low light condition and smaller screen, lower resolution.

Lumia 820 has a 2-kind plastic cover: regular one and supportively wireless charging system. This shiny cover is pretty slippery while keeping in hands but owing to the heavy weight of the phone (160 gram), in comparison with other high-class smartphone, it’s improbable for the phone to slip off the user’s palm.

The design of Nokia is a little different from Android smartphone when moving all the focus keys to the right side, include: volume adjustment, the power switch, the capture key. The headphone output is on top of the phone, and the speakerphone and the charging outlets is at the bottom of the phone.

Opening the cover of the phone will reveal many inside parts, especially all the pressing button at the right side such as volume adjustment, power switch and capture key. The exposed hard key circuits will be easy to break down if there is additional impact, or when using for a long time, dust and steam can stick to the phone and create oxidation phenomena which slowly corrode the hard key circuits. Therefore, users choosing this phone need to clean the phone regularly to avoid erosion. 

At the back of the phone, the camera and 2 led flash lights are closely designed by Nokia with a metal protection cover and scratch resistance glass, reduce dust from affecting the captured picture quality. 


Although the screen has low resolution, it still displays clearly the detail of picture; especially when having a slating look, the colors don’t change much due to the extremely high brightness. If using outdoors, the screen still has a good reflex, effective anti-glare function. The phone has automatic light sensor which helps to save battery, but if you don’t choose this option, adjust the brightness to the maximum level and use indoors, the color of the screen will become “striking”, making users feel unpleasant when using looking regularly at it.

The scratch resistance glass covers the whole screen firmly and takes the impact pretty well. To test this, use a pointed metal tip to strike continuously onto the screen, and this won’t leave any scratch on it. 

The screen always sets it automated looked mode but if you want to take a snapshot, you just need to hold the capture button for 1 to 2 seconds; at once, the phone will start its snapshotting function. Therefore, please notice if you touch or press the capture key mistakenly, because the phone will “automatically” run without notifying.   

In case you watch movies or have high-class 3D entertainment in several hours continuously, not only the back of the phone spreads heat but also the screen stars to become hotter, create unpleasant feeling if holding in hands.

During the test of Lumia 820, we updated more applications from Nokia collection and set up more applications from Windows Phone 8 store and the phone started to have the reset fault 2 to 3 times a day without the clear reason for that.


Lumia 820 has many stand-out features, for example Nokia City Lens users use camera to scan the surrounded pictures. The destinations such as restaurants, hotels, historical monuments, ATMs, parking lots, family restaurants… will immediately appear on the screen. The phone analyses the position correctly, even direct users, show the distance to these positions, but if using this function continuously, the phone will be flushed hot while hand holding. However, some destinations are fairly relative and the newer information is not updated, like the vestiges were destroyed or the restaurants were not in business anymore, ATMS were moved to another place…

Nokia Drive allows users to download map for free, 76MB in capacity. This function operates the same as a GPS without internet connection.

In test with 5km road, the map guides the main routes inside the city pretty correctly, the one direction turn and 2 direction turn are fully updated, but there is no update for time so it can notify you the traffic situation in rush hours. While turning to other roads to avoid traffic jam, the phone will analyze in a more crooked way. Since this is a trial version of Nokia, it’s hard to study all the ins and outs in the city.

With picture capturing, the phone camera doesn’t have Pureview features like Lumia 920, but thanks to the applications from Nokia like Panorama (panoramic photography), Cinemagraph (creating moving pictures captured from still ones), Creative studio (creating funny effects for the pictures), Lomogram (adjusting the picture effects like Instagram, PhotoBeamer (seeing pictures without connections), Smart Shoot (capturing and removing the objects in the background)… help users to comfortably create pictures captured from the phone.


Lumia 820 has the same configuration as Lumia 920, like Qualcomm S4 dual-core processor, 1.5 GHz speed, 1GB RAM, Adreno 225 GPU, 8GB storage capacity, support memory card slots, Amoled 4.3 inch screen with 800x480 pixel resolution, 8-megapixel camera, dual Led flash, 1650 mAh battery… so most of the applications run smoothly and there is no barrier when watching movies on Youtube or having high-class 3D entertainment.

On test of the high-end racing game - Need for speed: hot pursuit is continuous in a couple of hours, the heat spreads more, the screen becomes hotter and causes annoyance to users while they are hand holing. One of the inconvenient point in Lumina 200 software is that when users set the automatically battery-saving mode, turn the screen off for a minute, and when playing game like car racing with the back and forth shaking movements without touching the screen directly, after a minute, the screen will turn off automatically even though the game is continued on. However, this can be overcome in the new software updated version from Nokia.

Tested by using output measured application on Windows Phone 8, Lumia 820 has more outstanding score than HTC 8X. The possession of lower resolution screen makes the processing, calculating and graphic on Nokia model have faster processing time. With AnTuTu Benchmark, Lumia 820 gets 12,498 points, surpass HTC8X’s 11,475 points. Whereas using 2 other applications, Windows Phone Bench and MultiBench 2, in the comparison with 3 processing parts of CPU, Data, Nokia Windows Phone 8 and HTC, in turn, have the response time of 3,906 ms and 5,703 ms. The GPU graphic test of 820 reaches 40 to 50 frames/second and higher than that of HTC8X which only reaches from 33 to 37 frames/second.

Battery attached to the phone has 1650 mAh capacity, integrates light sensor function which helps to save battery so users can use all the features such as web-surfing, updating the social network, taking photos within 1 day. However, if adjusting the brightness to the maximum level, the phone can work for half a day satisfying all the continuous operations, especially when we use Nokia apps.
