When the solder on the solder pads is melted, use a pair of tweezers to separate the magnetic sensor from the screen.

If the solder isn't melted, apply more heat and try again.

When the area is cool enough to touch, remove the polyimide tape.

Use a pair of tweezers to remove the magnetic sensor cable.

The magnetic sensor cable is secured to the screen with light adhesive. Remove the magenetic sensor cable slowly to avoid damaging the cable under it.

During reassembly, apply a piece of polyimide tape under the solder pads while soldering the magnetic sensor to avoid damaging the screen.
