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.

820 is one of the impressive smartphones at the end of 2012.
Design
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.
Screen
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 screen has low resolution, it still displays clearly the detail of picture.
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.
Features
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.
Output
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.
