Friends, it will always be in your mind that do you need to put a screen protector on the screen of your phone? While on your phone, you have already been given the protection of Gorilla Glass or dragon tail. In this article, we are going to answer all your questions, so continue reading.

First of all, let me tell you that neither the company is making gorilla glass under the name Corning nor the company making Dragon Tail Glass, which is named Asahi, says that the glass we have is scratch-proof. Instead, they just state that our glass is scratch resistant which means it will prevent scratches to a great extent. However, if you got scratch in everyday use on your phone, then they will not fall due to this glass. But it is not that those glasses will not scratch; they will come, and I will tell you why it happens.

Why Does Gorilla Glass Scratch So Easily?

I will tell you a scale of hardness that we call the Mohs Scale Of Hardness. In this scale, each material is assigned a number according to its hardness, zero means softest, and ten means hardest, which is diamond. Now see if there is any material on this scale, suppose its number is 5, so this means that if you scratch on that material from any other material with a number less than 5, then there will be no scratch. But if you scratch with any metal above 5, you will get scratched.

Note: Number one in Mohs Scale of Hardness is Talc.


As we take an example, the number of copper is around 3, and the number of steel is about 5.5. So this means that if you put a scratch with a steel knife on the brick of copper, then it will be scratched. But if you try with a copper knife on a steel brick, then scratches are not going to fall on it. Similarly, let me tell you that the Corning Gorilla Glass, whether it is Gorilla Glass 2,3, or 4, and the Dragon Tail Glass, the number that comes on Mohs Hardness Scale is around 6.5.

Now the only difference between Corning Gorilla Glass 3 or 4 is that the same hardness has been retained, but the thickness of the glass has been reduced slightly and made the glass flexible. Other than that, it is not that Corning Gorilla Glass which is 4 is more scratch-resistant than 3, is not so. That is the only thing; his thickness has been reduced while keeping the same strength.

What Causes Scratches On The Gorilla Glass Screen?

Here, let me give you an example of our common household items which are in our pockets, whether it is coins, keys, or knives. If you force scratches with anything, then you will not get to see scratches in your phone, usually because the hardness number of all of them is less than 6.5. So no matter how hard you try to rub your phone with the key, your phone will not scratch if it has Corning Gorilla glass or dragon tail glass.

But there is one thing that can cause scratches on your phone, and you will never feel that scratches have come due to that, and that is sand. The sand contains quartz, and the quotient of the hardness of quartz is around 8 or 9. So now you think that if your phone has a little sand and tried to clean it, scratching your phone from the sand particles is very common.

No matter how carefully you keep the phone, if you live somewhere in a sanded area or if you live near the beach area, then scratching in your phone is very common. So what do you want to do in this case? If you feel that your phone has a Sad, then do not clean it by rubbing it with your hand. First, blow it as much as possible and then wipe it gently with a soft cloth. Friends, this is why, because now you have come to know about this hardness, what can not be scratched on your gorilla glass screen or in the dragon tail glass screen and can cause scratches on your phone.

Should We Use a Screen Protector?

Now I give you an example and tell me whether you use a screen protector on the screen or not? If you do, then which one to do? But the first recommendation would be that now definitely use whether you buy a phone of five thousand or fifty thousand as Replacement of the screen which happens is the most expensive in the phone. So if you have taken a phone of five thousand and if you have scratched your screen and want to replace the scratches that have come, then at least three thousand of your screen replacement will be in place.

Similarly, if you have used an expensive one, whether it is a note 5 or iPhone, I have guessed that its screen replacement is about 15 to 20 thousand. So why would you want for a 100 rupees screen protector that you take the risk of 15 to 20 thousand just to test that gorilla glass? As I already told you that they could scratch very easily with sand. From Nominal things, the scratch will not come like from the keys, etc. But scratch from the sand is very common.

Which One Do We Use Plastic or Tempered Glass?

Now see if you want to take a screen protector but which one is Tempered Glass or Plastic one. My opinion and what I have used myself to date is a plastic screen protector.

A tempered glass screen protector can also be scratched very easily because its hardness is also around 6 or 7. It is written in the box that its hardness is 8 or 9; while it is wrong, it is only around 6 or 6.5. So even if you scratch it with sand, it will be very easy to scratch, and it would be at least five to six times more expensive compared to a plastic screen protector.

After 6 months of using it, if it gets scratched and if you have to replace it, then your cost will be almost 10 to 20 times, whereas the plastic one goes a bit cheaper. As long as you have a slight scratch on it, it is okay now you can use them, in the same way, you can also bring it so easily in regular use, and when you try it, you can remove it easily and install another one. Nowadays, many phones get a complimentary plastic glass, so you do not even need to invest.

Tempered Glass Drawback

Friends, the drawback of tempered glass is that many phones nowadays which are screened by them are curved with a lighter side. In such a situation, if you use tempered glass, then it does not give complete fittings properly. From the side which has its borders, you get to see the air bubble there. I myself tried to use Note 4 and Note 5 once, but there are too many bubbles on the side, so you don’t even enjoy using them at all.

Also, it is a bit thicker from the top, so you do not get anything good on the phone, which is a touch effect. But once you put the plastic ones, then in a way you have applied them or not, you will never see the same thing on the screen. Use it for four or five months as long as you can, and if you want to replace it, you can replace it very easily. So I will not recommend tempered glass, but if you’re going to invest in it, then you can invest in it, but my recommendation would be plastic glass.


Overall, Gorilla Glass is a scratch-resistant and screen protection glass product from Corning to protect your smartphone screen from getting scratch due to everyday use. However, They don’t say it is scratch proof which means there is a chance to get scratch on your device; that’s why you a screen protector.
