How to Replace the Screen on Your Xiaomi Mi 4 Phone330

If the screen on your Xiaomi Mi 4 phone is cracked or damaged, you can replace it yourself with a few simple tools and a new screen. Here's a step-by-step guide on how to do it:

Tools and materials needed:* Replacement Xiaomi Mi 4 screen
* Phillips #000 screwdriver
* Spudger or plastic opening tool
* Suction cup
* Heat gun or hair dryer

Step 1: Power off the phone and remove the back cover

Before you start, make sure to power off your Xiaomi Mi 4 phone and remove the back cover. To do this, insert a spudger or plastic opening tool into the seam between the back cover and the frame. Gently pry up the back cover and remove it.

Step 2: Remove the battery

Once the back cover is removed, you will see the battery. Disconnect the battery connector and carefully lift the battery out of the phone.

Step 3: Remove the screws holding the screen in place

There are five Phillips #000 screws holding the screen in place. Remove these screws.

Step 4: Heat the screen around the edges

Use a heat gun or hair dryer to heat the screen around the edges. This will soften the adhesive holding the screen in place.

Step 5: Use a suction cup to lift the screen

Once the screen is heated, place a suction cup on the top of the screen and gently pull up. The screen should start to come loose.

Step 6: Insert a spudger or plastic opening tool

Once the screen is loose, insert a spudger or plastic opening tool into the seam between the screen and the frame. Carefully pry up the screen until it is completely detached from the frame.

Step 7: Disconnect the display connector

Once the screen is detached, you will see the display connector. Disconnect the display connector from the motherboard.

Step 8: Remove the old screen

Once the display connector is disconnected, you can remove the old screen.

Step 9: Install the new screen

To install the new screen, align the new screen with the frame and gently press it into place. Make sure to connect the display connector before fully seating the screen.

Step 10: Screw in the screws

Once the new screen is in place, screw in the five Phillips #000 screws to secure it.

Step 11: Reinstall the battery

Reinstall the battery by aligning it with the contacts and gently pressing it into place. Connect the battery connector.

Step 12: Replace the back cover

Align the back cover with the frame and snap it into place.

Step 13: Power on the phone

Power on the phone and test the new screen. Make sure that the screen is working properly and that there are no dead pixels.

Tips:* If you are not comfortable replacing the screen yourself, you can take your phone to a professional repair shop.
* Be careful not to damage the display connector when disconnecting it.
