How to check the "iron» iPhone 4 in order to avoid possible problems?

Looking at the cost of iPhone 4 in the CIS and especially conduct a "national business", unwittingly catch myself thinking that when you buy this gadget would like to verify the absence, as a minimum hardware problems. Today we will talk about the actions that will help you check the "hardware" of the smartphone and, at the same time, save a lot of nerve cells.

Perhaps most of the advice may seem obvious to you, but for some reason the buyer hopes for Russian "maybe", and when the defect is detected clutching his head and pronounce the sacramental phrase "why did not I think of that earlier?".

Before you connect your shiny new iPhone to your computer to sync with the iTunes first, pay attention to appearance Device: glass should not be scratched (believe me, when "certain skill" even the windshield may be damaged) and well adjacent to the edge of the steel at the lateral edge of the antenna gadget, all parts should adjoin each other is very tight, no backlash and creak.

Any slots not only contribute to the dust to enter the smart phone, but also reduce the structural integrity, increasing the chance of cracks and chips on the glass during accidental drops. To them, quite the contrary to become a powerful source of light and look at the iPhone profile. This should not be:

If you are satisfied with the look, feel free to go to the Review Home and Power buttons. They should immediately carry out their functions, but it does not hang or "sticky". However, their slight wiggle should not be a cause for concern.

These recommendations also apply to switch silent mode with only one addition: it should slide smoothly and immediately turn on the vibration motor.

Further "tests" require you to perform the initial synchronization with iTunes. But during it you may notice dock connector: USB-cable should not hang in it, and if something is wrong, the program simply does not see the iPhone, and the gadget will not be charged.

Occurred during the first synchronization errors may be the result of damaged flash memory - the percentage of such a marriage is minimal, but the people with him, too, sometimes faced - and, of course, we are not talking about one unsuccessful attempt (at the beginning it is necessary to address the basic tips for troubleshooting problems iTunes and search for information on the error code in the Internet). Also, you can "eyeballs" to score storage of multimedia content - this is a long process, but it clearly confirms its full functionality.

Finally, the end of the first synchronization, which means that it is time to test headphone connector and volume buttonsWe loaded because the previous step that you can listen to or watch. About a problem may indicate dangling headphone jack complete, no sound is to the left or right channel, broken buttons to control playback and microphone on the headset, which can be verified using a voice command or VoiceOver Diktofon.app application.

For check the front and rear chambers should take photos, it's obvious. You can also try out the possibility of «Tap to focus» function by sending the gadget to objects located at different distances from you. It is unlikely to succeed with your iPhone 4 to remove a masterpiece, which was destined to become the personification of the era, but the photos should not be noticeable defects. The same applies to recorded video, adjusting for smooth images and sound track.

There are many ways to test accelerometer. For example, using mobile or Safari iPod.app, activating Cover Flow. You can, of course, as some perverted in any program that supports text input, gain a couple characters and shake the gadget - thanks to iOS operating accelerometer prompts you to cancel the last input.

By the way, I would appreciate if you tell in the comments as regular or free means test the gyroscope.

We turn to the quality of testing communication iPhone 4. If you are in the coverage area 3G-networkThen for her to test you do not need to practically nothing. Is that to try to open in Safari a few sites and not try to play the legendary "death grip» (death grip), cause Antennageyta.

To switch to the mode EDGE / GPRS need to go to the Settings app> General> Network and turn off 3G-module. After a few seconds your phone should be switched to a slow (EDGE) or very slow (GPRS) data transmission mode.

Testing Of GPS-navigation it is impossible to imagine without the Maps application. Almost immediately after clicking on the special button in the lower left corner of the running application you will see a blue arrow pointing to your location. It does not fully apply to buildings with thick walls and ceilings, but even if outside the definition of the coordinate is not successful, the problem is obvious.

test module Bluetooth You can be accomplished by connecting of Bluetooth-headset or using the iPhone as a modem for your computer. I have experienced this a couple of times in my life, but nothing fancy was not in the two procedures.

Thanks to Wi-Fi module enabled by default, iOS will prompt you to automatically connect to a wireless network as soon as you are in its service area. Scanning of "air" and a successful connection clearly show the wireless module efficiency.

Rate the absence of "dead zones" in touch screen by using special multi-gesture (which is called «pinch zoom») in annex Fotografii.app / mobile Safari, or set each screen keyboard letters in all four possible device positions.

Checking dead pixels LCD-matrix It may result even begun, because the pixels do not have to be visible on retinal display. However, if you still want to make sure that there are no flaws iPhone 4 gorgeous screen, set him any free flashlight app from App Store, which allows you to display a variety of colors. The brightness of the backlight and the possibility of its adjustment can be checked in the application Nastroyki.app> Brightness using the corresponding slider. What about work light sensor It will be immediately visible in a dark room (this would require in the same window to include the item Auto-Brightness).

Start any intensive three-dimensional game, especially optimized for setchastochnogo display, allow to fully enjoy the opportunities CPU and GPU iPhone 4. In this case, a distorted or incorrect display of the image can be caused by problems with the graphics. Also, you can try to play in the pre-loaded application iPod.app h.264-high-definition video. It should play smoothly, without stuttering or obvious artifacts.

It left to spend only a few tests, but for this first call is required to make:

• Firstly, one of the main elements of any iPhone is microphoneWhich should work equally well in both the normal mode and in speakerphone mode.
• Secondly, a speaker unit you do not hear distortion or other audio interference.
• And thirdly, the proximity sensor is required to disable the iPhone's screen, if you hold it to his ear, and then return the smart phone to its original state.

All of the above tests will take you about 20-30 minutes, not counting the time for the initial synchronization. I am more than sure that if you specifically taken the smartphone there any problems with iron, they will show up in these tests.

I think you have noticed that the article does not mention another important component - the battery. It seems to me that it is simply impossible to quickly check. The remaining charge a smartphone up to 100% and, for example, leave it to play video for Apple claimed 10 hours.

Perhaps, that's all. If you know of an alternative / better ways to test those or other "iron» iPhone 4 components, do not be lazy to tell about it in the comments. Our readers will be very grateful to you.
