Do mobile phones really need a phone screen protector? Is your sticker on right? After reading it, I suddenly realized!

Smartphones are now very popular and are playing an increasingly important role.
In the past, when you went out, you had to remember to bring your mobile phone, keys, and wallet, but now you can basically forget your wallet, and you can pay with your mobile phone everywhere.
The appearance design is getting thinner and thinner, the screen is getting bigger and bigger, and mobile phones with full screens are more common.
What is the first thing we do when we get a new smartphone?
Basically, most people will put a phone screen protector on their mobile phone and put a protective case on it.
The question is, do mobile phones need a phone screen protector?
The point of view in support of the phone screen protector is: the phone screen protector can protect the screen of the mobile phone from being scratched, and it can also protect it when it is generally dropped.
The point of view in support of streaking is: the screen of the mobile phone is very hard and does not need protection, and the mobile phone needs to be replaced after two years, and the phone screen protector will affect the feel and screen effect.
Then let's compare the pros and cons of the phone screen protector, and see whether it should be phone screen protector.

The biggest function of the phone screen protector is to prevent scratches, so we must first understand a concept: hardness.
The Mohs hardness of common things is 2.5 for nails, 4-5 for iron, 5.5 for stainless steel, 6 for glass, 7 for sand, and 10 for diamond.
The screen material of the mobile phone is glass (hardness 6), so the car key (hardness 5) cannot scratch the screen of the mobile phone.

What are you most afraid of on the phone screen? sand! Grit on the ground and in your pockets is the main culprit for scratches.
No matter how advanced a smartphone is, the screen is still made of glass. Therefore, if the phone is not covered with a phone screen protector, it may be scratched. The time for scratches is related to the environment in which it is used.
Give the first conclusion: the screen of a mobile phone without a phone screen protector will produce scratches after a long time of use.
The material of the phone screen protector also varies from good to bad, ranging from a few dollars to hundreds of dollars, so what is the difference?
In terms of material, there are two common types of phone screen protector, one is plastic phone screen protector and the other is phone tempered glass screen protector.

The hardness of the plastic phone screen protector is 2-3, so it is easy to wear, and the hardness alone can be vetoed.
No matter it is high-definition, frosted, mirror, or anti-peep, it can't make up for the defect that it is easy to scratch.
Moreover, the so-called anti-blue light and anti-ultraviolet rays are all suspected of being fooled.
The phone tempered glass screen protector is made of glass, and the hardness of special tempered glass can reach 6.5 (note that it is not as hard as sand)
The phone screen protector can protect the screen of the mobile phone itself, giving the mobile phone screen a chance to be revived with full blood.
The most important thing is the material. As long as it is made of glass and the quality is not too bad, there is no big problem.

In addition to anti-scratch, the phone tempered glass screen protector can also resist falls to a certain extent.
If the corners of today's large-screen mobile phones touch the ground, and it happens to be tiles, it is difficult not to break the screen.
The phone tempered glass screen protector can play a certain protective role, and the broken phone screen protector is actually the hero because it replaces the mobile phone screen.
Some people say that mobile phones are bought for use, not for supply.
That's right, but the phone screen protector can improve the durability of the phone, it is a preventive measure, isn't it good to plan ahead.
