You need to prepare a knife with intact tip, a piece of clean cloth, a hard card like phone card or discount card, and electric hair drier. Firstly, wipe the screen with the clean cloth. Then peel the protective film and stick it to the screen from one side and press it with the card from that side at the same time. There will be no bubbles between the screen and the film this way. If the film curls, you can heat it with the electric hair drier and pull it at the same time.
1. Wipe away the dust on the surface of the screen with the fibrous cloth attached at first. When you wipe the screen, you should wipe in the same direction. Don't do it back and forth. 2. Then determine the direction in which you will stick the film. And peel down a small part of the release film marked as "step1" and get ready to stick it. 3. When you stick the film, you should peel down a part of the release film and align it at the screen. Then stick it to the screen and tear the release film at the same time until the whole film is sticked to the screen. 4. When it's done, tear off the second layer of release film marked as "Step2" . 5. Finally completely tear off "Step2" release film. Then you can use it without worry.
