Help: My iPhone, 4 Fatal Problems

The machine was bought in **? Hurry up and find the seller, if the warranty is within the warranty period, hurry up and replace one

Refurbished machine, there is a problem with the hardware, no way. Let's find a dealer and change the machine with the board.

To solve the first question, you can click Set Brightness and turn off the automatic adjustment.

This one is definitely an issue with the machine itself, I've never had this issue before!

The traffic "runs" fast (turn off the "notifications" function in the iPhone settings to reduce automatic networking).

There is no sound when you call, and the call needs to be hands-free to hear the sound (this situation is generally caused by the moisture of the mobile phone and enters the headphone mode.) You can use the electric air to blow the hot gear against the earphone jack and the tail charging port for a period of drying).

The camera is not working (go to Settings - General menu and select Reset Phone, it will fix the problem).

Heat up (turn off background programs that are not in use).

Crash (force Apple's device to shut down by pressing and holding the "Power On" button and "Home" button for more than ten seconds).

In addition to the above problems, Apple phones will also have a red and blue screen phenomenon (restore the phone firmware), the phone screen flashback (go to the software running in the background, manually turn off part of the running software) and so on. Generally, after the problem with the mobile phone, you can choose the method of booting and restarting the phone, and try it first.

Touch failure.

Some users have reported that the iPhone 6 and iPhone 6 Plus have certain problems in terms of screen touch sensitivity.

The camera screen is black. On some iPhone 6 and iPhone 6 Plus, after some users turn on the camera, the screen will appear black, and this problem also has a chance to occur when rotating **.

Bluetooth is lost. Bluetooth connection issues are also relatively common. It is reported that the problem of not being able to connect to Bluetooth devices on iPhone 6 and iPhone 6 Plus is especially common in car Bluetooth.

Fingerprint error. The complex process of Touch ID has not been spared, and some users have reported that the sensitivity of fingerprint recognition will be problematic from time to time. This is mainly because of the consequences of Apple's carelessness when releasing iOS.

Press and hold the power button + home button until the Apple logo appears on the screen. (Generally about 10 seconds) 2In some programs, after entering certain words, the program rewinds in seconds.

Solution: Open Settings, General, and restore the keyboard dictionary. 3.

**Can't dial out, can't hang up, the other party connects to the normal mobile phone when called, and the text message can't be sent. Solution: Generally, there are many cases when using a mobile card, after setting the cellular data correctly, turn on the cellular data and let the mobile phone connect with the Internet.

4.The screen interface suddenly expanded. Workaround:

Tap the screen three times in a row with three fingers at the same time. 5.Tapping the screen will speak.

Solution: In this case, it means that your phone has turned on the voiceover function, and press the home button three times in quick succession. (It can also be --- settings--- general --- accessibility features --- turn off voiceover)6

There is no sound when you call, and the call needs to be hands-free to be audible. Solution: This situation is generally caused by the dampness of the mobile phone and enters the headphone mode.

Adjust the volume to see if there is a hint (headphone mode). You can use an electric fan to blow the hot gear against the headphone jack and the tail charging port for a period of drying (time to grasp by yourself).
