The protective element of the screen in modern smartphones is glass, which has replaced plastic resistive touchscreens. But glass, compared to transparent polymers, has one significant drawback: it is fragile. One small blow and the screen becomes covered with a web of cracks. In order to prevent such an outcome, tempered glass with increased strength is being actively developed. Their most famous manufacturer is the American company Corning, famous for its Gorilla Glass brand.
Gorilla Glass is a glass with a special composition that has been subjected to chemical and physical processing. Its purpose is to modify the structure of the material to increase resistance to scratches and impacts. Another advantage is that it reduces the risk of injury: shards of tempered glass do not have very sharp edges. When using a smartphone with cracked glass The risk of cutting your finger is significantly reduced. The same goes for a phone screen accidentally crushed in your pocket.
The idea of using chemical treatment of glass to impart strength was born in the first half of the 20th century. Then soda-lime glass was invented, which has increased reliability. In 1959, Corning began testing various methods chemical processing of glass. Then, using alkaline compounds and aluminosilicate, Chemcor glass was created, which was later used in aviation and motor vehicles. But it was not widely used.
Everything changed in 2006, when Apple began developing the first iPhone. The plastic of resistive touchscreens quickly wore out and scratched, which Jobs did not like. The Apple leader turned to Corning management and proposed reviving the technology. At that time, the company was already independently trying to resume research in this direction. Cooperation with Apple has allowed us to significantly increase investment in development. As a result, the first generation of Gorilla Glass was born.
Gorilla Glass is made using ion exchange hardening technology. Classic silicate glass is immersed in a melt of potassium salts, heated to temperatures of about 400-500 degrees. Under their influence, weak sodium ions in the glass are replaced by stronger potassium ions, which increases the strength of the product. Thanks to the strengthened molecular bonds provided by chemical hardening, Gorilla Glass' hardness on the Moss scale reaches 6 points (out of 10, the hardness of steel is about 5).
The thickness of Gorilla Glass was about 1 mm, while the impact resistance was up to 3 times greater than that of conventional tempered glass. For 2007 (when the thinnest smartphones were thicker than 10 mm) this was a normal figure. But soon the thickness of the device began to decrease, and there was a lot of extra millimeters.
Gorilla Glass 2
In January 2012, the company introduced the second generation of tempered Gorilla Glass. By that time, Corning's development had already been used in more than 200 million smartphones around the world. A new version Gorilla Glass has become 20% thinner, with an increase in strength qualities up to 4 times. Engineers have improved the technique of saturating workpieces with potassium ions, ensuring their deeper penetration. This made it possible to make the layer saturated with them thicker.
Gorilla Glass 3
To make Gorilla Glass 3, released in January 2013, more durable, the developers have improved the technology. According to the manufacturer's statements and tests, it can withstand loads greater than sapphire crystal. Native Damage Resistance technology made it possible, with the same thickness, to increase strength by 3 times (compared to the second generation). Scratch resistance has increased by 40%, and impact resistance has become 50% higher.
Gorilla Glass 4
In the new generation of glass, shown in November 2014, the manufacturer managed to reduce the thickness by 2 times, bringing it to 0.4 mm. Other characteristics (strength, resistance to impacts and scratches), however, remained at the level of its predecessor. The purpose of the new glass is to reduce thickness mobile devices without compromising their protection. According to the creators, it is 2 times stronger than coatings made using competing technologies.
Alternatives to Gorilla Glass
Competing companies are not standing still and are developing alternative coatings for screens that have increased durability. One of them is sapphire glass, created by the synthesis of this mineral. It is highly resistant to scratches (only diamond and some synthetic substances can leave a mark), but it is more fragile and also expensive.
The Japanese company Asahi, specializing in the development of new brands of glass, has also succeeded in this field. In 2011, it released Dragontrail, a more affordable alternative to Gorilla Glass. It is slightly inferior to its competitor in terms of strength properties, but is 6 times superior to ordinary glass. Due to its low price, Dragontrail is in demand among Chinese manufacturers, such as Xiaomi, Lenovo, Meizu. Even Sony equips their Z series flagships with it.
In Germany, Schott is developing a competitor to Gorilla Glass. Their development, Xensation Cover, also claims to be one of the most durable types of glass. Its presentation took place in 2012. As of 2016, the most renowned manufacturer The company using Xensation Cover is the Chinese company Meizu. Glass is used in new budget smartphones of the M3 series.

Best models
It is obvious that not only flagships, but also cheap phones receive protective glass from Corning. However, on expensive models, high-quality and durable Gorilla Glass 5 is used, and on budget phones they can use Glass 2 or 3. Below - the best devices, which received protection from Corning.
1st place – HTC U12 Plus
The best flagship in subjective opinion at the end of 2018 is the U12 Plus from the famous HTC brand. It runs on Android 8.0 out of the box, but will definitely receive an update to Android 9.0 and most likely 10.0, although there is no word on when that will be.
The device with a Super LCD screen has high picture quality, its diagonal is 6 inches with a resolution of 2K, which gives a pixel density of 537 per inch. Naturally, it is covered with protective glass, however, this is not new protection, but just Corning Gorilla Glass 3. This is strange, since the company's previous flagship - U11 - uses Corning Gorilla Glass 5. But oh well, even with such protection the phone does not It gets scratched if it's in your pocket with your keys.
At the back there are 2 rear cameras with resolutions of 12 and 16 megapixels, optical stabilization and f/1.75 aperture. Video shooting is available in 3840x2160 format and even shooting at 60 FPS, although there is nothing new here.
The processor is Snapdragon 845 with Adreno 630 video core, that is, the device’s performance is excellent. Also, the HTC U12+ has 6 GB of RAM, 128 GB of memory and a 3500 mAh battery. The manufacturer claims that it lasts for 23.8 hours of talk time, which is a good result. The highlight of the phone is the side touch panels Edge that respond to compression. We squeezed the smartphone and a side column with a menu appeared. They can also be programmed for other actions.
An excellent and reliable device with protection from Corning. Recommended for purchase.
2nd place – OnePlus 6
The flagship is good because it is devoid of unnecessary flagship “arsenal”: there is no water protection, a 3D face scanner, touch-sensitive side panels and other bells and whistles. But there is the most powerful hardware, an excellent shell, and most importantly, optimization of performance and energy consumption.
It’s not for nothing that OnePlus 6 became the first smartphone in terms of performance, equipped with a Snapdragon 845 processor. Speed, absence of friezes and brakes, power reserve for the next 3-4 years, stable software updates and support, build quality – all these are the advantages of the device.
The screen is with a 6.28-inch diagonal Amoled matrix and 2K resolution. Unlike the HTC U12+, this device received a protective glass, scratch-resistant Gorilla Glass 5, which is sure to withstand a drop or a slight blow, not to mention scratches. Many buyers use the device without additional protective films and glass - the “native” protection is enough.
3-4 places – Samsung Galaxy S9 and S8
It is appropriate to place 2 phones at once in this position - S9 and S8. Both have reliable Corning Gorilla Glass 5 protection on both sides, so the phones are not afraid of drops and scratches. Naturally, within reasonable limits.
Effective protection against water - the devices work even under water, - build quality, the best Amoled screens (recognized by the Display Mate studio) with automatic correction colors for the user, proprietary Exynos processors and TOP technologies, including face recognition and iris scanning for unlocking. It’s not for nothing that these flagships have a high price.
Many users don't like it new Galaxy S9 is not an acquired taste, so we give phones 3-4 places. If they were cheaper, it would be appropriate to put these phones in 1-2 positions in the rating.
5th place – Xiaomi Mi 8
New TOP phone Chinese brand Xiaomi made with Gorilla Glass on the front and back. The phone received an Amoled matrix with a diagonal of 6.21 inches and a resolution of 2K. There is a “unibrow” at the top, and the display itself occupies 88.5% of the entire area.
SoC – Snapdragon 845, 6 GB RAM. Of course, the speed of the device is high. Plus, it uses cool rear cameras. You can find their review with photo examples.
The device operates under Android control 8.0, will receive an update to 9 in the future. Build quality, speed, optimization - all this is at high level, as befits a flagship. It is recommended for purchase, although it is difficult to find the phone in stores - it was sold out within hours after the official start of sales.

Nowadays, smartphones value not only performance, but also quality. The main thing in smartphones is resistance to falls, scratches, and water. Therefore, safety glass is gaining popularity. Gorilla Glass can definitely be called the most famous protective glass. It is used in the manufacture of telephones. Protective glass is also used in tablets.
According to statistics, every person drops their device about 10 times a year. So many falls can break your tablet/phone to pieces. Gorilla Glass really helps with the fear of breaking your phone.
For example, on smartphones Nokia Lumia Has Gorilla coating. The smartphone falls at a distance of 1.5 meters onto the asphalt, but remains completely undamaged. This is far from the only example proving the effectiveness of such protection. A large number of experiments were carried out to test the effect of glass. It successfully passed all tests. Many users specifically look for smartphones with this coating.
The first mobile phone with such protective glass is Nokia N8 (2008). The use of screen protection became especially important after the appearance touch phones. This explains that touch screen highly susceptible to mechanical damage. This glass is made from aluminum silicates.
On this moment There are six generations of Gorilla Glass:
- Gorilla Glass 1(2008).
- Gorilla Glass 2(year 2012). The glass is 20% thinner and is difficult but possible to scratch.
- Gorilla Glass 3(year 2013). It is 40% more resistant to mechanical damage, 50% more resistant to impacts.
- Gorilla Glass 4(2015).
- Gorilla Glass 5 falls from a distance of up to 1.6 m without damage.
- Gorilla Glass 6 has indicators twice as good as those of the fifth generation. At the moment, glass of this generation is the best, most reliable and strongest. But manufacturers don't stop! They continue to look for new combinations and conduct experiments to create even more perfect glass.
Many manufacturers of both expensive and budget brands use Gorilla Glass protective glass, which has proven itself to be excellent.

Protective glass Gorilla Glass - why is it so popular?
Corning revolutionized the mobile industry in 2005 by creating a special material made from Al (aluminium), O (oxygen) and Si (silicon). His main feature became light weight, small thickness (about one and a half millimeters) and high strength. It is very difficult to damage such a film.
However, at that time the technology was used in different industries (automotive, household appliances), but began to be used in smartphones only in 2007. It was then that Apple introduced its first iPhone with special screen protection and oleophobic coating. To find out if your smartphone has Gorilla Glass, follow the link to the official Corning website, select the brand, and look at the list of phones. Second version
5 years later, at the high technology exhibition CES 2012, the manufacturer presented improved glass. It was 0.3 mm thinner and could withstand a load of no more than 50 kg per square meter. The most popular devices with Gorilla Glass 2 were Google Nexus 4 and Samsung Galaxy S3. Third generation
Each subsequent update differed from previous developments in improved strength and resistance to scratches (thanks to the introduction of Native Damage Resistance technology) and other damage. And again the thickness became smaller and amounted to about 1 mm.
The list of phones with Corning Gorilla Glass 3 includes the following well-known devices: Samsung Galaxy S4, Motorola Moto X/G.
Many people are still interested in the question: is additional film needed for such phones? After all, salespeople in stores are constantly trying to force all sorts of accessories on us.
In fact, there is no need for such expenses. Gorilla Glass 3 provides excellent protection against scratches. But nothing more. However, in the next generation this problem was partially eliminated. Useful content: What is OTG in a smartphone: how to use it?

The fourth version was introduced in 2014. When creating it, the wishes of thousands of owners were taken into account. mobile gadgets. They all complained that the screens had low level protection from falls (and such cases have become quite common with the increase in display diagonal and dimensions of smartphones).
The manufacturer took these comments into account. As a result, the strength increased almost 2 times. ASUS ZenFone 2 and Samsung Galaxy Note 5 successfully passed a number of crash tests, thanks to the “fourth Gorilla”. Corning Gorilla Glass 5 - what kind of glass is it?
The fifth generation became one of the most popular and was widely used by device manufacturers even in mid-price range models.
The official test results ensured that even if dropped from one and a half meters, the screen would not be seriously damaged. Small cracks are possible.
And if the height is up to a meter, then the probability of damage approaches zero. Again, the thickness of the film became less than a millimeter, which had a positive effect on the weight of the produced gadgets - Xiaomi Mi A2, Samsung S9. Sixth version
At the time of writing this review, Gorilla Glass 6 is the latest modification. It was released in the summer of 2018. Security increased by 90%. Many Youtube bloggers conducted independent tests on their channels, in which they tested the recent flagship Samsung Galaxy S10 from different heights (at waist level, head level), on tiles, asphalt, soil, carpet, linoleum, etc.
Often, after 10 attempts, the screen received only minor damage. So far, a coating with such characteristics is used only in TOP-level devices - OPPO R17, iPhone Xs/Max. To find out if your smartphone has Gorilla Glass, follow the link to the official Corning website, select the brand, and look at the list of phones.
The modern smartphone has long become something more than a means of communication and communication.
For business people it is a sign of status, for young people it is a multimedia entertainment center. Many users want a device that can perform any task, and some people care about appearance. As they say: “You meet people by their clothes...”.
We have selected best smartphones, which received a unique design thanks to the glass coating.
Attention! The selection includes devices released before April 2016. Prices are also April.
Samsung Galaxy S7
The flagship is not only in design, but also in technical features. First of all, it is worth noting the glass coating on the front and back panels. The manufacturer itself calls it 3D, since a similar rounding of Gorilla Glass 4 has not yet been used.
The flagship is certified to the IP68 standard, so it is not afraid of dust, dirt, rain or submersion, although the latter is in doubt.
The performance indicators of the flagship are very high and can compete with any representatives of the premium class. Smartphones with Snapdragon 820 and Exynos 8890 processors have been released for different markets, the RAM capacity is 4 GB, and the internal memory is available in several versions: 32, 64 and 128 GB.
Price: from 50,000 rubles.
Samsung Galaxy S6 Edge
At the time of presentation, the smartphone was recognized as the best design solution. This effect was provided by glass panels that had a rounded shape. There were also unique colors on display that looked absolutely gorgeous under glass.
The manufacturer did not stop at the ideal design and equipped the device with top-end equipment. The device received an 8-core Exynos 7420 processor and 3 GB of RAM. The amount of internal memory is available in three versions: 32, 64 and 128 GB. The 16 MP main camera is equipped with an optical stabilizer, and the battery capacity is 2600 mAh.
Cost: about 45,000 rubles.
Despite some complaints regarding the design, it turned out to be very attractive. All this is the result of a good combination of body materials - metal and glass. The latest smartphone covered on both the front and back sides. At the same time, the screen received smooth tempered glass, and back panel covered with curved glass with a 2.5D effect.
The 2016 flagship is the . This reputation was ensured by the Snapdragon 820 processor and 3 GB LPDDR4. Together with graphics adapter Adreno 530, the smartphone turns into a coherent system, ready to perform any task. The amount of ROM can be 32 or 64 GB. The 3000 mAh battery supports Quick Charge 3 technology.
Price: about 30,000 rubles.
The gadget is covered with Gorilla Glass 3 on both sides, and there are metal frames on the sides to ensure its safety in case of falls. Appearance ordinary and does not stand out in any way: the presence of a glossy glass surface does not add much charm, and the device is available only in white and black colors.
As for performance, everything is quite simple here too. Small amount of RAM (1 GB) and 8-core MediaTek processor MT6592 provide stable operation and performance standard features. The device has an 8 megapixel main camera and a 2050 mAh battery.
Price: about 13,000 rubles.
A bright representative of the budget class of devices, distinctive feature which the appearance became. The back panel is made entirely of tempered glass and has some special features: it contains the company logo, which is illuminated during charging or unlocking.
The phone is powered by a quad-core processor, 1GB of RAM and 16GB of internal storage. This is quite enough to perform standard daily functions.
Another smartphone from Lenovo, but of a higher class. Essentially, it is a camera phone, the design of which is similar to digital cameras, for example, Sony T100. The body is covered with Corning Gorilla Glass 3 on the front and back sides, the remaining parts are framed with chrome-plated metal.
