Some people mistakenly think that all 
Android phones
 that come out of China are white-label devices with no support and no 
hope of future upgrades. That is true of some phones, but not all. China
 has several popular international brands including ZTE, Huawei and 
Lenovo. ThL is another brand that is popular in China where it has over 
340 stores across the country. Its phones are also for sale 
internationally from places like Chinavasion. The 
ThL W100
 is its latest smartphone and it was launched only this week. Not only 
does this phone have a 4.5 inch IPS display, sport a quad-core Cortex A7
 based processor, include an 8MP rear camera along with an amazing 5MP 
front-facing camera, it only costs $169! That makes it the first branded
 quad-core Android smartphone to be offered internationally for less 
than $200.
Hardware
At the heart of the W100 is the MTK6589, a quad-core A7 processor 
designed for low power but yet quad-core performance. A7 cores are 
becoming increasingly popular and are starting to replace the Cortex A9 
cores that were popular in dual-core phones. By using the A7 core 
the MTK6589 is able to reduce its energy needs, but at the same time 
offer quad-core performance. Here are the full specs of the ThL W100:
- 4.5 inch, 960 x 540, 5 point multi-touch IPS display
- Android 4.2
- 1.2GHz MTK6589 quad-core CPU
- PowerVR SGX 544MP GPU
- 8MP Rear Camera + 5MP Front-Facing Camera
- RAM: 1GB
- Dual-SIM
- 3G: WCDMA: 850/2100MHz
- 2G: GSM 850/900/1800/1900MHz
- WiFi: 802.11 b/g/n
- GPS
- Bluetooth
- Full support for Google Play
- Micro SD Card Slot
- Proximity Sensor
- Accelerometer Sensor
- Light Sensor
- Magnetic Field Sensor

The device is 134 mm long, 70 mm wide and 9 mm thick which is 
reasonable considering the 4.5 inch display. However the phone 
is amazingly light. It weighs just 102 grams and when I first picked it 
up I thought I had forgotten to put the battery in! Much of 
this lightness is achieved by using lots of plastic, so no 
aluminum uni-body designs here, but still it is pleasure to hold.
The phone only comes with 4GB of internal storage that is divided 
into 1GB phone storage and 3GB external storage. This can be a problem 
for larger apps or games as they simply won't fit into the 1GB of phone 
storage. However the good news is that a microSD card can be added and 
in the settings the microSD card can be set as the default write 
location. This helps keep the price down but doesn't leave the 
user frustrated with no hope of expanding the storage.
Although the resolution of the screen is “only” 960 x 540 the display
 is remarkably high quality. The IPS screen has excellent viewing 
angles, the colors are vibrant and when on full brightness the screen 
doesn't look washed-out.  Below is a photo comparing the same image on a
 HTC One S, a Nexus 7 and the ThL W100. Although the HTC One S offers 
deeper coloring, I think the W100 is actually the best of the three 
displays (in terms of color at least).
 
Connectivity
The phone has all the standard connectivity options like Wi-Fi 
( 802.11 b/g/n), Bluetooth, 2G GSM and 3G. It doesn't have NFC nor does 
it support LTE but for only $169 that isn't a problem!
There are two SIM card slots both of which can be used for normal GSM
 services and messaging but only one of which can be used for 3G. It 
doesn't matter which slot is used for 3G as everything 
is configurable via the settings. Which SIM is used by default to make 
calls, which SIM is the default for SMS and which SIM should be used for
 3G can all be set accordingly. Both slots are unlocked and will work 
with any SIM card, contract free.
For 3G the phone only supports 850 and 2100MHz.  The latter number is
 the “normal” 3G frequency and should work in most places around the 
world, however a lot of carriers also use a secondary 3G spectrum range.
 In Asia this tends to be 850MHz, as supported by the W100, while in 
Europe it tends to be 900MHz. I tested the 3G slot with a local carrier 
which uses 2100MHz and 900MHz networks. The 3G worked fine but the range
 and effectiveness wasn't as good as a phone that also supports 900MHz. 
The 3G connectivity will be optimal in areas with only a 2100MHz network
 or with a 850MHz/2100MHz network.
I compared the Wi-Fi signals strengths of the W100 with a HTC One S 
and a Nexus 7 using the free “Wifi Analyzer” app from the Google Play 
Store. The W100 performed just as well as those two devices and I was 
able to access the Internet from all around the house and outside 
without any problems.
Software
The phone runs Android 4.2.1 Jelly Bean and includes Google Play and 
Google Now. The phone is running a slightly tweaked version of stock 
Android. The most noticeable difference is the transparency of the app 
draw. When the app draw is opened the background (but not the desktop) 
can still be seen. It is visually pleasing and a nice touch from ThL. 
The other thing I noticed was that the settings app uses color icons. 
Other than that, everything looks to be stock Android.
The device supports Google Play and although not all 
the official Google apps like YouTube etc are pre-loaded, it is a simple
 matter to install them via the Play Store. Using Google Play was simple
 and I didn't encounter any “incompatible” apps. All the top free, paid 
and essential apps like Twitter, Yahoo! and Facebook all 
reported compatibility with the W100. For those who like customization 
it is worth noting that the phone isn't rooted by default.
 
Performance
The MediaTek MT6589 is becoming increasingly popular at the lower end
 of the quad-core smartphone market and since it uses one of the the 
latest core architectures from ARM, it is a good choice for this phone 
(and other in the range).
I previously tested the 
5.8 inch, 720p Mithril
 phone which uses the same processor and the results are very similar 
with the W100 getting slightly higher benchmark results mainly due to 
its smaller screen (and hence less effort needed by the CPU/GPU).
The phone scores 13,041 on AnTuTu (compared to the Mithril's 12,737).
 Putting that into some context it means that AnTuTu rates the W100 as 
being faster than the Google Nexus 7, the Asus Transformer Prime (both 
of which are Tegra 3 quad-core devices) and faster than the Samsung 
Galaxy Note. Similarly the W100 scores 4006 on Quadrant putting it on 
par with the Asus Transformer Prime. For further comparison the 
ThL W1,
 which is powered by a 1GHz dual-core Cortex A9 based MT6577, 
scored 6436 on AnTuTu and 2737 on Quadrant. Older dual core phones like 
the HTC One score just under 7000 on AnTuTu. Overall the phone performed
 well and there was no lags or annoying pauses. It felt as fluid and 
usable as any of the Android devices I have at hand, maybe even better.

A quick test using Epic Citadel showed that the W100 can manage an 
average of 47.4 frames per second at 960 x 544 using the high resolution
 mode. The Tegra 3 based Asus Transformer TF300 manages 46.5 FPS and the
 Nexus 7 53.7 FPS.
Camera
The W100 includes an 8MP camera which takes vibrant pictures and is 
certainly well beyond what to expect in this price range. Also the 
inclusion of a 5MP front facing camera is remarkable. The built-in 
camera app includes features like face detection, 
HDR, continuous shooting and panorama. The camera works well for 
quasi-macros shots and I was able to get a good focus lock on objects 
even when quite close. The dandelion picture below demonstrates this the
 best.
 
 
 
Battery
In the box ThL provide two 1800 mAh batteries. The advantage of two 
batteries is that you can leave home with both fully charged and know 
that you will get double the battery life during long journeys or times 
away from a mains socket! The device includes a fairly standard USB 
mains charging adapter and the phone can also be charged from a laptop 
or PC since charging only requires 500mA. My battery tests revealed that
 the ThL W100 can play video for about six hours on one charge. In 
another test I found that a full battery will allow you to watch YouTube
 videos over Wi-Fi for about five hours or play heavy 3D games for about
 three hours.
Conclusion
For those with questions about buying 
electronics online from China, see our guide (
part one, 
part two)
 – it isn't as difficult as you might imagine. For $169 this phone could
 be missing half the features it has an I would still recommend it! OK, 
this isn't a Samsung Galaxy S4 or a HTC One, but it costs a lot less 
than they do. The W100 has a quad core processor based on ARM's low 
power consumption Cortex A7, a vibrant IPS display, good connectivity 
options, reasonable battery life and a nice 8MP camera. The support for 
only 850MHz and 2100MHz on the 3G  side could be limiting to some, but 
there are other advantages like dual-SIM support plus features like GPS 
and a compass. All that from a branded Chinese company for just $169.
