Generally speaking, the mobile phone is only attached to the screen body, and there is little film. If the mobile phone is painted with bright paint, it is easy to get dirty or paint will fall off, but it is recommended to stick an electrostatic film, which is not effective and easy to leave glue marks. But if you stick a butterfly film alone, it really works. With it, you can get rid of the pain of getting stuck in the phone case. There may be a little trouble, because the film is integrated and needs to be pasted on the front and then on the back. Don't worry when you can persist step by step. And because of the material problem on the back of the phone, there may be obvious bubbles just after it is attached, but don't worry that it will disappear with the phone case in a while. I feel quite cool after posting it. So it's best not to cover the envelope.
