Replacement of screen on iPhone 12 touch screen made by LaptopScreen.com

Tools

For the installation process, we'll need the following tools: heat gun, suction cup, plastic pick,
small tri-wing screwdriver

The front assembly consists of the frame, the glass digitizer, and the LCD screen. You will
need to replace the entire front assembly if any of these components are broken.

Shut down the iPhone

To begin, turn the phone off by holding the power button and confirming shutdown on
screen.

Open the iPhone

Remove two pentalobe screws at the bottom of the phone.

Use a heat gun to warm the adhesive around the perimeter of the iPhone. Place a suction cup
near the bottom edge and, while providing some tension, insert a plastic pick between the
display assembly and the main body. Move it along the edge. Continue warming the device
with a heat gun. Apply some pressure with a plastic pick to separate the front assembly from
the main body as you go around the perimeter.

Please note: there are cables located near the left edge of the phone. Keeping that in mind,
open the iPhone like a book to the left side.

Disconnect the connectors

Now we have access to the connector shields. Using a tri-wing screwdriver, carefully remove
two screws securing the small metal shield, then remove the shield. Using a plastic pick,
disconnect the battery connector, followed by the LCD and touchscreen connectors.

Using the same tri-wing screwdriver, remove four screws holding the big metal shield.
Using a plastic pick, open the speaker and sensors connector. Separate the screen
assembly from the main body.

Remove the remaining adhesive

We will be replacing the waterproofing adhesive, so all of the original adhesive needs to be
removed from the edge of the phone.

Apply the new adhesive

The waterproofing adhesive comes on convenient plastic sheets cut to the exact shape of the
edge of the phone. Remove the backing plastic of the adhesive sheet. Apply the shape to the
perimeter of the phone and, using a plastic pick, press the adhesive firmly into place.
Carefully remove the top carrier plastic, making sure that the adhesive stays on the
perimeter of the phone.

Connect the new display assembly to the main body

Take out the new front assembly and place it along the left edge of the phone. Carefully
reconnect the touchscreen connector and the LCD connector, then reconnect the speaker and
sensors connector. Replace the big metal shield and secure it with four screws. Reconnect the
battery, then replace the small metal shield and secure it with two screws.

Close the iPhone

Now we can test the device. Close the iPhone, reconnect the charger, and press the power
button. The screen is working, so we can finish the reinstallation process.

Close the phone tightly and, using a soft cloth, apply some pressure to the sides of the
phone, snapping the display assembly securely in place.

Replace the two pentalobe screws at the bottom. Turn the iPhone on, and we are done!
