Front Screen Glass Lens For IphoneX12promax with OCA

                                                                     Solution to the failure of mobile phone capacitive screen

  Option One:

1. Turn off the phone, take out the battery, and let the phone stand for about five minutes.

2. Find a USB data cable and connect it to the phone.

3. Wash your hands, or wet your hands (a key step, in order to better discharge the static electricity).

4. With wet hands, the thumb of the same hand touches the metal part at the other end of the USB cable, and the index finger touches the ground for about two seconds (preliminary power-off).

5. After removing the back cover, we can see a small metal block next to the battery compartment. This is the vibration generator of the mobile phone, commonly known as the vibrator. Since it is also directly connected to the motherboard of the mobile phone, we can do the same thing, touch the vibrator with the thumb of the same hand in a wet state, and press the index finger to the ground for about two seconds.

Option II:

The easiest way is to stick it with transparent tape. When the tape is quickly removed, part of the charge will be taken away, just like the physical friction of glass rods and rubber rods in junior high school. In addition, the adhesive tape will stick away tiny dust, sweat stains, salt, etc. on the surface of the screen. These tiny things will also affect the charging of the screen, so I think it should be repairable if you stick the adhesive tape several times.

  third solution:

Blow the screen with a hot hair dryer (hair blower), pay attention to turn it on to the mid-range, blow it evenly and feel that the screen is hot (note: the battery must be removed)

Option four:

Remove the battery of the mobile phone, turn on the electric iron, press the sheet on the bed sheet, the temperature should be moderate, remove the electric iron, turn the screen of the mobile phone on the hot sheet, and iron the screen cover (the temperature should still be moderate, do not repeat ), and so on about 5 times.

Option five:

Open the back cover, remove the insulating paper wrapped on the outer surface of the battery, expose the negative pole of the battery, put the battery back in, and turn it on. When the capacitive screen fails, just take off the back cover, touch the negative pole of the battery directly with 4 fingers, and touch the screen with your thumb. If it still doesn’t work, touch the negative pole of the battery with your thumb, it will definitely work this time.
