How to solve the partial failure of the touch screen of the Apple 4S mobile phone

In general, it's a matter of wiring.

It should be good to replace it.

Of course, it is also possible that the internal wiring (ITO) of the screen is not only a problem, if it is internal.

There's no way around it.

I can only change the screen.

PS: The latter cases are relatively rare.

If the mobile phone is in the warranty, go to the after-sales maintenance center to change the screen, the detection is not human, and the screen will be changed for you for free, if it has been guaranteed, there is no need to go to the repair center to change, you can go to an ordinary repair shop, or buy a screen online and come back to find someone to replace it, so it is cheap.

TFT screen is currently the most commonly used and most common material on the screen of mobile phones, TFT full TFT--ThinFilmTransistor thin film transistor, is one of the active matrix type liquid crystal display AM-LCD, TFT sets a special light tube on the back of the LCD, which can actively control each independent pixel on the screen, which can greatly improve the reaction time.

There are many reasons for the failure of the touch screen, including hardware damage, software damage and systemic damage. Battery failure or use of heating also malfunction, the specific fault is not easy to determine, it is recommended not to change the screen first, restore the mobile phone factory system, disassemble and clean, remove the mobile phone screen for inspection.

Apple 4S screen suddenly does not respond may be stuck screen of death, the recommended treatment method is as follows:

1. When you encounter the iPhone stuck screen of death, can't turn on, and there is no response, you can try to press and hold the power and home button on the home screen at the same time and keep it for more than 10 seconds. See if you can force a restart.

2. If the forced restart is successful, you can see an Apple logo on the screen afterwards. After the reboot is successful, it can be used normally.

3, of course, sometimes it may be because of the power out, resulting in automatic shutdown, no matter how you operate, you can't turn on the phone, when you encounter this situation, please connect your iphone to the power charger first.

4. If it is automatically turned off because of the lack of power, a battery icon will appear on the screen at this time.

5. In addition, the battery of the iPhone must be charged to more than 5% before it can be turned on normally, if the power is extremely low, please let it charge before turning it on.

6. If the above methods are ineffective, it may be a hardware failure of the Apple mobile phone, and it is recommended to send it to an Apple authorized after-sales service store for testing.

Apple will also crash, especially after upgrading iOS7, reboot it!!
