Tell if the phone is a broken protective film or a broken screenMethod:

1. Pick up the mobile phone and scratch the crack on the surface of the screen with your fingernails, if you feel an obvious crack, the protective film of the mobile phone will be broken;

2. The eyes look at the screen from the side, as shown below. If you can see another shadow on the screen below the phone from the crack or there is a sense of drop, the phone protective film is broken. Because there is a certain thickness between the protective film and the mobile phone, if the mobile phone film is broken, you can see the spacing on the mobile phone screen from the crack.

3. Directly tear off the protective film of the mobile phone, if the screen is broken, you also need to tear off the protective film to change the screen, if the protective film is broken, then replace the protective film and tear off the original. Therefore, directly removing the protective film is the most direct and reliable method.

4. If the screen is broken and the details are found, if the crack is found, or the degree of fragmentation is radiated outward from a point, the screen is broken, if the crack is evenly distributed, and there is no screen without defects or debris, it is a broken protective film.

You can roughly judge by touching the screen of your phone. If you can't feel the crack if you don't open the tempered film, it means that the tempered film is broken, and if you can only see the crack but can't feel it, it means that the screen is broken.

Method 1: Heads-up method.

First of all, the eyes and the screen should be basically parallel, and observe whether the crack can be seen in the light, if the crack can be seen, it means that the tempered film of the mobile phone is broken, but if you can't see it, it means that the mobile phone screen is broken.

Method 2: Tilt method.

Pick up the mobile phone, tilt the angle of about 30°, and observe whether the cracks of the mobile phone film and the cracks of the screen coincide from the side. Because if both screens are broken, the cracks on the phone will not coincide.

Method 3: Touch method.

If there is a slight crack or spread on the screen, you can gently touch the crack with your fingers, and if you can feel the crack with your fingers, it means that the tempered film is broken. However, if the fingers do not feel the crack and can only be seen through the eyes, it means that the screen is broken.

Generally, the crushing of the tempered film will not affect the display of the screen, nor will it affect the touch of the screen.

If the screen is broken, it will be divided into a broken inner screen and a broken outer screen. If the inner screen is broken, a black screen will be displayed, and no content will be displayed; The outer screen is broken, but it can't be operated on the screen, the touch fails, and the screen content will be displayed.

1. You can touch the surface of the tempered film with your fingernails or fingers to see if there is a concave and convex feeling, and if there is a concave and convex feeling, it can be preliminarily determined that the tempered film is broken; 2. Under the premise that the tempered film is broken, tilt the mobile phone to observe the crack surface, whether there is more than one crack, and whether the glow of each color of the mobile phone screen in the dark state has the phenomenon of smudging or black spots. If there is, you can basically determine that the screen is broken; 3. You can also check the display content after opening the screen, such as backlight, color difference, water ripples, red screen, black spots, yellow spots, flickering and other color problems. If you feel that the touch does not work when you touch and slide, it should be caused by damage to the inner screen.

To determine whether the tempered film is cracked or the phone screen is cracked, you can distinguish it by the following methods.

1. Have an eye to observe whether there is a crack on the surface, and then finger the location of the light membrane crack. If it is rougher than other positions, it means that the tempered film is cracked. The light membrane of the finger is cracked from time to time, and there will be a feeling of obvious unevenness.

2. No matter which crack it is, the tempered film needs to be uncovered when it is replaced or repaired, so the tempered film is uncovered, and the tempered film and screen are used to see which one has a crack and which one is broken.

The most direct way to judge is to uncover the tempered film, which is more intuitive; In addition, you can also observe the crack at an angle of about 30 degrees, and if there is only one crack and it floats on the surface, then it can be concluded that only the tempered film is broken.

If the film is broken, take it off and look at it

Damn, you can't even see this, you can't see it, you can't see it.

Here's how to tell if it's a tempered film or a broken screen:

1. In the case of sticking to the film, if there is only one crack and floats on the surface, the tempered film will be broken. Because if both screens are broken, the cracks that appear will not coincide.

2. Observe the crack on the side of the film at an angle of about 30 degrees, if the crack is only one and floats on the surface, then it can be concluded that the tempered film is broken. Because if both screens are broken, the cracks that appear will not coincide.

3. If it is a slight crack is diffuse, you can go to the belly of your hand to gently touch those cracks, if you can feel the crack is the tempered film is broken, and it is broken if you can't feel it smooth and can only be seen.

There is a big difference in appearance between a broken screen and a broken tempered film, which can be judged by the following aspects:

1.Cuts: If you can feel a cut at the edges when you slide your finger across the screen, it's likely that the screen itself is cracked. And if there is no obvious cut feeling when swiping across the screen, it may just be that the tempered film is broken.

2.Observe the color: When the screen is cracked, cracks and color changes often appear in the cracked area.

If the color of the screen darkens significantly or changes color after a crack, it is likely that the screen itself has cracked. And if the color of the crack does not change, or there is only some debris on the surface, it is likely that the tempered film has cracked.

3.Observe the inside of the screen: Press the screen with your hand to observe whether there is any liquid crystal leakage or blurred screen.

If this happens inside the screen, it's likely that the screen itself is cracked. And the cracking of the tempered film will not affect the function inside the screen.

4.Look at the crackage: After the screen is broken, there are often large or multiple fragments, and the rupture of the tempered film will only form some small fragments in the local area.

In general, there is a clear difference in appearance between a broken screen and a broken tempered film. If the crack of the screen is obvious, the color change is obvious, and it will affect the internal functions of the screen, then it can basically be concluded that the screen itself is broken. And if there are only a few small debris and the inside of the screen is functioning normally, then it is likely that the tempered film is just broken.
