How can the screen and body of a mobile phone stick together when they are separated?

The method for repairing the separation between the screen and the body of the mobile phone is as follows:

Demonstration machine: Huawei nova5z.

System version: HarmonyOS V2.0

Tools needed: sucker, E8000 screen adhesive, rubber band.

1. Hold the screen with a suction cup and lift it gently, then observe the position of the screen gap. Remember not to pull the screen hard to avoid damaging the screen.

2. Squeeze a proper amount of E8000 glue into the gap evenly. If it is an LCD screen, you must not inject too much glue to prevent the glue from flowing into the backlight layer and causing backlight shadow.

3. After injecting glue into all glue areas of the screen, press the screen in time to restore it to its original position, and then fix the screen with rubber bands for 4 to 8 hours to fix the problem.
