If your phone already has a screen protector, proceed to the next step.

Using an infrared thermometer, heat the surface to 70-80oC. This will weaken the glue, but will not damage the electronics.
-
Hold the hair dryer at a distance of 7-8 centimeters from the phone (approximately as in the picture). After setting a weak hair dryer mode, heat the frame for three to five minutes, depending on the strength of your hair dryer.
-
Be careful! If you overheat the matrix, you can cause color distortion. If you notice the slightest color distortion, turn off the hair dryer immediately.

If you work with a hair dryer, it may take up to an hour.

At this step, you need to be very careful not to damage the buttons or cable! Using a spudger, separate the buttons from the inside of the glass. It may need to be warmed up a bit. Perhaps the best option is to start in the middle, under the middle cable connecting the two buttons, then separate each button.
