You may ask yourself, do I need a screen protector when using a high-end mobile phone in 2022? Why use a screen protector when the screen is hard? Something is not adding up, which I will shed light on today in this article.
Why Use a Screen Protector when the screen is hard? How Hard is Toughest Screen In 2022?
The hardness of life of most items is not as good as that of mobile phone screen glass. Under normal circumstances, the screen hardness value of ordinary mobile phones is 6 (unit: Mohs hardness), and the hardness value of Corning Gorilla Glass is 7-8, far exceeding most Item hardness.
For example, the hardness of fingernails is 2, the hardness of ordinary keys is 5, and the hardness of knives is 6. It can be seen that it is difficult to cause damage to a mobile’s screen using most hard objects. So, why do so many people stick to mobile phone screen protectors?
Relationship Between Quartz’s Hardness And That Of Mobile Phones
That’s because there is a common mineral in life, it is called quartz, which is usually mixed in common sand and gravel, and can be seen everywhere on the roadside.
In addition, this mineral is also diffused in the dust; put your mobile phone by the window for a few hours or In a day, you can see a layer of gray on the mobile phone screen, which contains fine quartz.
Quartz has a Mohs hardness of 7, larger than that of ordinary mobile phone screen glass. Although it does not affect Corning Gorilla Glass, the Mohs hardness of most mobile phone screen glass is 6, which is still easily scratched.
If you are sure that the glass of your mobile phone screen is Corning Gorilla, maybe the quartz will not damage the screen, but the glass is low in brittleness, and it will still shatter when it is dropped from a high altitude.
Therefore, in fact, the tempered film protects the mobile phone’s screen from scratches and reduces the probability of breaking the screen when it is dropped from high altitudes.
Always Use A Good Screen Protector(Preferably Tempered Glass) For Your Phone.
Therefore, it is recommended that you stick to the tempered film and choose the tempered film correctly. Please be careful with cheaply tempered films. Especially the ones that sell for $9 for three pieces. The cheap film may not protect the screen and affect the look and feel.
As a final note, i strongly recommend a tempered glass screen protector where applicable.
