What should I do if the screen of the Apple 7P mobile phone fails and the touch screen does not resp

This is an Apple mobile phone that is broken and can be repaired in my store, and it can be repaired at the repair point.

The two most expensive things on the iPhone, in addition to the motherboard, are the screen, and the glass screen is extremely fragile. It may be a screen failure caused by static electricity problems, or a screen failure caused by system jamming or software conflicts, or a failure caused by a trigger IC failure.

Static electricity causes the screen to malfunction temporarily. Especially in winter, the static electricity problem is more serious, such as the iPhone is left for a period of time, when it is just turned on, and suddenly finds that the screen is not very sensitive or malfunctioning, then it may be caused by static electricity problems. The solution is to hold the iPhone, touch the ground with the other hand or touch the wall, and the static electricity will disappear; Or wipe the screen two or three times in one direction with the palm of your hand to remove static electricity.

After removal, the lock screen will be used normally when it is turned on again.

The screen is malfunctioning due to system freezes or software conflicts. During use, if the mobile phone screen fails to freeze or freezes, you can only wait for a while, wait for the system to react, or force restart the phone. It is very simple to force restart the Apple phone, as long as you press and hold the home button and the power button at the same time, and when the phone is turned off and the Apple logo appears again, let go of your hands.

The touch screen fails due to a faulty touch IC. This problem mainly appears on the iPhone 6 Plus, and the way to identify whether the touch IC is faulty is also very simple, just press the screen and pat the machine to know.

The screen cable is loose, damaged, or the inner screen is malfunctioning. If you can eliminate the above three faults, it is a problem with the screen itself. If the cable is loose, you can re-buckle the lower cable, if it is invalid, then you need to replace the entire screen.

Here's how to solve the problem:

1.Reboot. The first thing to do is to restart your iPhone 7 and press the "Sleep Wake" button (which is what we often call the power button) and the Home button at the same time until you see the Apple logo on the screen.

2.Reset. Some users resolve the issue by selecting Settings - General - Reset - Reset All Settings. The user will need to re-enter the password, change the wallpaper, and reset the Touch ID, but the user's data will not be deleted.

3.Return to the factory for repair.

Users who encounter the failure of the iPhone7 touch screen also solve the problem by restoring the factory settings, but all the information on the phone will be lost, so users need to back up the important data in the phone in advance. After that, users may need to set up their iPhone 7 like a new phone, and some users say that restoring backed up data from iTunes or iCloud will cause this problem to recur.
