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 recognize 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.
Specification
External
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 is 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.
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 sound And vibration switch. 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 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 color distortion at all.
Resolution iPhone Classic.
Retina resolution of the iPhone 4.
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 colors just so.
Try a little bit compared to the Galaxy S.
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. Simply 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.
Connection.
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, dtac and TrueMove with the 2G spectrum that supports all iPhone 4 wave 850/900/1800/1900 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.
Camera
Back of 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.
Gyroscope.
Almost every modern phone models are put Accelerometer, 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 thatAccelerometer (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 chart. 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 in order to measure more precisely sure enough offline.
