Your new iPhone 4 has hardware problems?
Do you like this story?
You have just bought the iPhone 4 and want to know if there are hardware problems? You will get one from a private individual and want to be sure to buy it? Then read our tips on how they make sure that the hardware device is perfect.
* Appearance: The iPhone must submit a cover flawless, no scratches and no dents (of course ...);
* Buttons: all must work gently. Try the Home button, the sleep button on top, the volume buttons and the vibration button (on the latter made a couple of tests to be sure that it works well);
* Dock connector and flash memory: Connect the device to iTunes and make sure it is recognized and charged by the computer where the iPhone is recognized, but it appears some error message, then there may be a problem with the flash memory;
* Input Jack: insert the earphones and listen to system sounds, try the volume buttons. Clicking on the button for a few seconds the headset can activate the voice over, so you can test your microphone headsets;
* Microphone and speaker: If you have the opportunity to try a call, activate the speakerphone and test the proper operation of the speaker and microphone. The entry must be clear and without distortion;
* Multi-touch: To ensure that there are dead spots on the screen and write notes taken using the keyboard, vertically or horizontally.
* Screen: check well the screen, perhaps in Settings, where white abounds, to be sure that there are areas "yellowed"
* Bluetooth: try connecting the headphones or computer via Bluetooth;
* Wi-Fi: make sure that the connection is working properly and the signal is weak when you are near the router;
* 3G: If you are in an area with good coverage, test the 3G connection;
* EDGE / GPRS settings from disable the 3G network and try to surf the Edge;
* GPU / CPU: All games should work without delays and applications open in an instant.
* Battery: take this test by putting a video playback and brightness by default. The estimated time of battery life according to Apple is up to 10 hours, if it lasts less than 7 then there is a problem.
* Compass, GPS, accelerometer, proximity sensor, and Grioscopio: Use the free application Sensor Monitor to test all these functions.
