Nokia Lumia 2520 Comprehensive Review

Nokia Lumia 2520

Nokia Lumia 2520 is the first Windows tablet from Nokia. It comes with the recognised Lumia design and is only 8.9mm thin. The tablet is 615 grams heavy, which means it is not so light as it looks. The tablet is equipped with Windows 8.1 RT, which we find a significant disadvantage because RT gives insufficient options for a tablet. A full Windows 8.1 would be better for a tablet like this. This is the first and probably the last tablet from Nokia, which we find a great new because a tablet from Nokia (especially with limited RT Windows) is a disaster. But let’s take a closer look at the specifications of the device:


The device is equipped with Full HD IPS LCD capacitive touch screen display, protected by Gorilla Glass 2. Well, this is nowadays a standard, so we are not surprised by the display of Lumia 2520.

Something new for the Lumia devices – microSD card slot for up to 64GB external memory. The RAM of the instrument is 2gb, which may be enough for everyday use.


The Lumia devices always come with great cameras and super-quality Carl Zeiss optics. This time we feel a little bit disappointed because the tablet has the only 6.7MP camera. Some may find it enough, but Lumia devices are usually proud with their camera, well this time not. The second camera with the 2MP sensor is here as usual.


Quad-core 2.2 GHz Krait 400 is the CPU of the device. For the RT version of Windows, this is more than enough, but an Intel CPU would be better with the full Windows OS.

Non-removable battery with 8120mAh is placed in this device. The numbers are great, but we all know that all Lumia devices have high brightness and huge battery drain. If this is not enough, with the Nokia Power Keyboard, you get +5 hours of battery life.

Nokia Lumia 2520 Tablet


Here is something positive we can say about this tablet, and it is that this is one of the few LTE tablets we can see on the market. With its 4G connectivity, you can download up to 150mbps.

To conclude, I wouldn’t recommend this device as its specifications are not as good as the competitors. Though this method gives an excellent connectivity and beautiful Lumia design, its limited OS ruins almost everything. We would rather recommend a tablet like Acer W510/W700 or even the more expensive Microsoft Surface Pro 2, instead of choosing this tablet.

Sony Xperia Z1 Review


It is the first compact smartphone on the market yielding the power and all the extras of its flagman under a 4.3-inch display.


The design of the mini is almost the same as that of the flagman. It has the same power button, the Omnibalance design, a stable metal frame, but with a modified back panel. The back panel, while in the flagman is made of glass in the mini it is made of plastic. The difference is unnoticeable but the plastic back of the Z1 Compact is more vulnerable to scratches and if you are used to keeping your phone in the same pocket as your keys that will eventually lead to a scratch “collection”. The Compact followed all for the buttons from the Z1, but the slots for the micro sim, micro SD and micro USB have been moved to the left side of the phone.

Dust and water proof

AS expected of Sony, they have kept the dust and water resistance typical for the Xperia series. This way the Z1 compact covers IP55 and IP58, which means it is 100% dust proof and can withstand a 1-meter dive for up to half an hour. The waterproof corpus is identical to that of the flagman and is better than that of the Samsung Galaxy S5. Do keep in mind that the water resistance applies only to freshwater so don’t go swimming around with the phone in the salty seas.

A better display than the Xperia Z1?

Xperia Z1 Compact offers a significantly better quality screen. The size of the screen is 4.3 inch, the resolution has been lowered from FULL HD to HD. In other words, the pixel density is lower than the Xperia Z1 (342 to 441 ppm). And it still offers more detail than the iPhone 5s.

Here Sony has used the same Triluminos technology for a larger variety of colours, but the most expensive new add-on here is the IPS technology – this is key to image quality, the effect of flowing icons on the surface and no lightening of the picture under any angle. This is what makes the Z1 Compact display better than the Xperia Z1

Power of the flagman

“The device has a 16gb built in memory + a microSD slot for up to 64 GB more.” One of the unusual characteristics of the Z1 compact is the powerful Snapdragon 800 chipset, which we are used to seeing mainly in devices with a 5.5++ inch displays. The mini also possesses the Qualcomm. Besides the Quadcore CPU of 2.2 GHz and the graphic chip Adreno 330, Compact has 2 GB RAM, which puts its productivity to the maximum – no glitches, no slows and no spontaneous freezes.

Unchanged camera

The camera is another one of the elements of the Xperia Z1 Compact that remains unchanged from the flagman. Just like in the Xperia Z1 here we find the same 20.7 MP camera with an Exmor RS sensor, the Sony G lens and a software processor for BIONZ for image processing and editing.

Other companies have reduced the pixels and removed optical stabilisation from their mini versions, whereas Sony keeps everything the same. The Compact offers an identical photo viewing interface as the Z1. The so called Smart Social camera offers a great variety of additional camera applications. In it you will find the: Info-eye, which gives information for a documented wine bottle, a book or even a landmark; Social Live allows the streaming of real life time videos directly to Facebook; Time burst for a series of fast shots.

The frame quality of the pictures is quite good and if you are familiar to the Xperia Z1 – the pictures in the Compact are no different. With the Xperia Z1 Compact, you will have one of the best camera phones on the market, but Sony is still a long shot away from the Pure View of the Nokia Lumia 1020 and 1520, but this applies to all other companies as well.

Battery life

The only thing that “shrunk” alongside with the display is the battery. Compared to the 3000 mAh battery of the Xperia Z1 the Xperia Z1 compact battery is a bit less robust – 2300 mAh. It works great though and can keep the phone “alive” for up to 48 hours if not used to the limits or a day and a half average regular work. The battery is out of reach for the consumer as the body of the Xperia Z1 Compact is sealed. The phone uses a micro USB to charge or a magnet charger, which some traders include in the pack.

Sony Xperia Z1 Compact – The best mini on the market

With this device, the Japanese company has shown us that a powerful, compact, easy to use a smartphone can be real. Sony has not only created the most powerful droid with such a small size, but they gave their competitors Samsung and HTC something to thing about on for their next mini. Processor, camera, water proof body with a metal frame and an excellent display are just some of the elements of the Sony Xperia Z1 Compact that make it the best 4.3 inch Android at the moment and most probably for the next 6-12 months.

Review iPhone 4

iPhone 4

At this time the mobile is hot and has been the most talked about in Thailand.Which version would be none other than I offline iPhone 4.

I believe most readers will recognise iPhone as a very good already.So I intend to review, with emphasis on new features.The increase in iPhone 4 iOS 4 and compared with the previous generation iPhone I offline.


  • CPU ARM Cortex-A8 (Apple A4).
  • GPU. PowerVR SGX535. (Apple A4).
  • Main memory 512 MB.
  • Both versions capacity 16 GB and 32 GB.

The outward appearance of the iPhone 4 will be unlike any previous generation iPhone materially change the exterior design is a rectangular shape.(จับวางตั้งได้ไม่ล้ม!), while still maintaining the traditional approach of buttons.

Front and rear glass are the same used to make glass more durable than a simple plastic helicopter.Machines around the sides made from a special alloy that is stronger than usual.It serves as an antenna with personally, I like this design more than any previous version I offline.

The home button has a single button the same.Box next to the speakers in the camera image page facetime play out for themselves or take pictures.

Button up / down soundAnd vibration switch.The position remains the same.

Below is a microphone, speaker jack and a USB cable as their predecessors.

Top it with the Power button and headphone jack 3.5 mm, the same small hole next to the headphone jack is the microphone to talk Facetime, including 2 for use in noise at the normal telephone with offline.

Insert the SIM card slot for moving to the right instead.The shift from a traditional micro-SIM Sim, smaller than

Try Sheep Micro SIM tray out.(Ameแsongdgyiแฮa!).

The camera also is the same but with additional side LED Flash.

Retina Display.

Apple iPhone 4 named the Retina Display screen by screen name came because of the high-resolution images of the cells as much as the human eye (Retina) can not distinguish each of the pixel points.

iPhone 4 is produced for the screen by LG has a resolution of 640×960 pixel 3.5-inch screen is a TFT-LCD screen. IPS. Angles, which can be viewed from almost 180 degrees with no colour distortion at all.

Resolution iPhone Classic.

Comparison between the view on the TFT screen iPhone Classic (left) and the IPS screen on the iPhone 4 (right) will notice that the iPhone Classic screen is enough to change the view.Color will be distorted accordingly.

When maximum brightness iPhone 4 (left) is brighter than the iPhone Classic (right) rather

iPhone Classic tilt even more crazy colours just so.

Try a little bit compared to the Galaxy S.

iPhone 4 or iPhone 4s

Two microphones.

iPhone 4 to 2 the microphone to the noise.The first is the bottom like the previous version.The other option is a small hole.Next to the headphone jack on offline.

Principles of noise, nothing more.Just remove the sound from the mic to the lower, less noise from the mic on the issue.But it left the mouth of the speech because the speaker is close to the mic first rather than offline.


iPhone 4 is another unique feature in that supports 3G 800/850/900/1900/2100 MHz frequency waves, which covers all the main frequencies in the world to be used in any country with 3G.Wave experiments, including AIS, data and TrueMove with the 2G spectrum that supports all iPhone 4 wave850/900/1800/1900 MHz as mobile online offline.Nothing strange.

For the iPhone 4 Wi-Fi capability to connect to 802.11n in the 2.4 GHz frequency with offline.


Back to the iPhone 4 Camera resolution 5.0 MP, Auto-focus a touch, LED Flash and video shoot 720p which is not something new for the camera what mobile offline.

The Camera page.0.3 MP resolution obviously not as much.But enough for offline play Facetime.

Rear view camera images from the news I was offline.

iPhone 4 will officially expire on 31 October


Almost every modern phone models have put accelerometers, which can be measured only by acceleration.Know only that the phone is held at an angle where the earth is different from the Gyroscope Accelerometer.Direct measurements of the rotation or angular velocity.Check out images from the sensor would be more understandable.

The above picture is placed on the iPhone 4 rotating chair to chair and so on.The image is observed that accelerometer (chart above) will know only that we are hand held horizontal to the ground by the axis Z (blue), a force of about 1g (the acceleration of the world), but can not be measured, I was moving chairs are opposed to. Gyroscope (chart below) that can read out the speed of rotation as the blue graph.If you observe that the end will fall table.That is why I have to stop the chair to press the screen capture.

In summary, Gyroscope improves the ability to measure the movement of the iPhone to measure more precisely sure enough offline.


iPhone 4 for sale in Thailand come with all iOS 4.1, which is the OS with many new exciting features such as
