There are 3 methods suggested for removing the lens film as follows:

1, For some common mobile phone lens protection film, you can usually start from one corner, gently cock it with your fingernail or the edge of a credit card, and then gradually tear it off along the edge. Please note that this process needs to be done carefully to avoid scratching the lens or leaving adhesive marks.

2, you can try to use a hair dryer to blow on the lens film for a few minutes, so that the adhesive on the film is softened by the hot air. Remember to set it to hot air and keep it at a distance to avoid damaging your phone with high temperature. After blowing, you will find that the lens film becomes easy to tear off.

3, if you have medical alcohol at home, it is better. Dip a cotton swab into an appropriate amount of alcohol and gently wipe the edges of the lens film. Alcohol can dissolve some of the glue and make the film come off more easily. Be careful though, alcohol is flammable, so be sure to keep it away from fire sources when using it.

There are 2 methods suggested for removing the screen protector as follows:

1- Use your fingernail to lift up a corner of the glass film. Snap your fingernail down until it touches the bottom of the tempered glass film. You should be able to barely lift one of the corners of the glass film to get it off the surface underneath. Take your time and don't rush. Lift it up carefully, don't try to rip it off in one go.

2 - Heat the tempered glass film with a hair dryer on a low temperature setting for 15 seconds. The high temperature will loosen the glass film and make it easier to peel off. However, only heat it briefly on the low temperature setting to avoid damaging the parts underneath. Blow the window film until it is warm, but not so hot that you can't touch it.
