Loosen the inner adhesive

Apply a few drops of high-concentration (90% or higher) isopropyl alcohol under the right edge of the screen to weaken the inner adhesive near the fingerprint sensor.
Insert the isopropyl alcohol applicator near the top of the inner adhesive area to avoid damaging the fingerprint sensor.
You may apply the isopropyl alcohol without inserting the applicator into the phone if needed.
Tilt the phone so that the isopropyl alcohol flows toward the inner adhesive.
Wait two minutes for the alcohol to weaken the adhesive.

软化内部粘合剂

在屏幕的右边缘下方滴几滴高浓度（90％或更高）的异丙醇，以减弱指纹传感器附近的内部粘合剂。
将异丙醇喷头插入内部粘合区域的顶部附近，以免损坏指纹传感器。
如果需要，你可以在不将涂药器插入手机中的情况下涂异丙醇。
倾斜手机，使异丙醇流向内部粘合剂。
等待两分钟，让酒精减弱粘合剂的粘性。
