Some precautions when handling gadgets can not be called redundant. Even novice users are well aware that touch screen refers to the number of expensive elements, the replacement of which costs a substantial amount. Significantly increases the strength of the device special glass, protecting it with a small mechanical impact. many owners mobile phones prefer to glue the protection on their own, without contacting service center. As a result, after such attempts, noticeable air bubbles appear that spoil appearance screen. Let's talk about how to get rid of such a nuisance, what exactly can be done for this ordinary user without technical knowledge.

Ways to eliminate air under protective glass

2. When you fail, do not despair. Get a small needle, which you will need to carefully pry off the edges of the protection. Use a needle in those places where the accumulation of air impurities is noticeable. After the air is removed, firmly press the protective element against the screen of the gadget.
3. A standard hair dryer can help. It takes a few minutes to warm up the smartphone a little. In no case do not bring the hair dryer close! The equipment should work at a distance of 25-30 cm! After the event is over, put electronic product on a flat surface under the press of several heavy books. After about 6-8 hours, only a memory will remain of the air bubbles.
4. In the presence of a large number of blisters, it is worth resorting to a more radical method. It is possible that the air under the protective glass will disappear after the complete dismantling of the protection.

We will provide useful information, which will help to avoid problems when installing a thin accessory.
Don't forget to remove greasy stains from the screen surface. Be sure to use a liquid with a high alcohol content to achieve this goal. Do not forget to wear disposable medical gloves that do not hinder movement and allow you to perform precise work. Remember that the sticky side of the accessory should never be touched. In this case, the adhesive parameters of the coating deteriorate significantly. The ideal option among professionals is the presence of a suction cup, it greatly facilitates the process of completing the task.

By the way, the quality of work, in many respects, depends on what kind of glass you have purchased. Practice proves that failures occur much more often when trying to stick cheap copies. Therefore, never save on protection, purchase only expensive copies.

Today we will tell you whether a smartphone really needs a protective glass and whether it can protect the gadget when it falls. We will also tell you which glass to choose and how difficult it is to install.

The need for glass

When buying a smartphone, sellers often offer to glue a protective glass as an addition, while assuring that it is absolutely impossible without it. If the display breaks, they continue, it will be easier to buy new phone plus scratches.

They are right that the price tag for display replacement can be up to 60% of the cost of the device. But otherwise there are nuances. If the device is budget and it does not have the so-called protective tempered glass, then yes - it is better to stick protection on it, otherwise scratches cannot be avoided, and even when dropped, the glass absorbs a little.

But devices of average price category with a screen made using Gorilla Glass or Asahi technology, they do not need a piece of plastic 0.33 or even 0.22 mm thick, such a device is not afraid of scratches. Displays with Gorilla Glass are practically not scratched.

Impact on sensor performance

A persistent myth is that glass impairs sensor performance. Actually, it is not. The only thing is that there may be no oleophobic coating on the protective glass, and just a bunch of fingerprints will remain on the display, and the finger will slide worse than on a “bare” screen. The smartphone sensor may not respond well if the glass is poorly glued.

Glass or film

Glasses are a relatively recent phenomenon. At first they were popular on iPhone and Sony devices, but later the trend spread to all other models.

Of course, it is better to stick glass. Firstly, it is much easier to glue than a film, especially on a new device. Secondly, it gives, though small, but still additional protection.

But there is an important clarification here. If you have a 2.5D display with rounded edges, then a regular screen protector will not stick around the edges or cover the entire screen. Therefore, it is necessary to clarify whether the glass will accurately cover the entire screen.

Real cost

Prices for glass sometimes reach up to 2000 rubles, which is not very cheap. Is the high price justified?

Not really. There are really expensive glasses from manufacturers such as Samsung, LG, etc. They are made for curved displays, there are also glasses with colored frames to match the color of the device. Their price tag can reach up to 1000 rubles. The purchase price of simple transparent glasses from little-known manufacturers is 50-150 rubles per piece.

Which glass to choose

Present on the market great amount glasses from different manufacturers, which one to choose?

curved screen

If you have a smartphone with curved screen, then it is advisable for him to buy a special glass with a 2.5D, or 3D effect. Otherwise, it will not stick around the edges or cover not the entire screen. Moreover, the inscription “2.5D” on the glass packaging does not mean anything. It is better to ask the seller whether it is accurate to full screen or not.

colored frame

It is best to avoid glass with colored frames. If transparent glasses are glued over the entire surface, then in colored glasses there is glue only at the edges. Also, they very often have a “gasoline stain” on the screen, which cannot be eliminated .

Oleophobic coating

A good oleophobic coating prevents finger grease from remaining on the screen. The screen on such devices is always clean. For protective glass, such a coating may be worse than that of a smartphone, or completely absent. Therefore, before buying glass, it is better to move on it and see if prints remain and how easily your finger slides.

Matte or glossy

This is of course a matter of taste. In our opinion, glossy glass is better. Although it glares in the sun, but with it you do not need to twist the brightness to the maximum in order to see the image.

Thickness

In fact, it is not particularly important how thick the protective glass is - 0.22 or 0.33 millimeters, you will not notice the difference.

Installation

Many people think that there is some kind of special adhesive for installation or that it requires special equipment. In fact, there is nothing complicated in gluing, and on the packaging of glass, as a rule, there is an instruction with pictures.

1) First you need to degrease the surface of the screen and remove all rubbish from it. To do this, complete with glasses, the manufacturer puts alcohol and dry wipes.

2) After cleaning the screen, we apply the glass, after removing it from it protective layer. There is a special sticker on the glass for this.

3) Gently apply the glass to the screen so that it does not go beyond the edges. That, in fact, is all. Glass is glued on.

If it doesn't work the first time, don't worry! Glass can be picked up with something, such as a toothpick, and try to re-glue it. If rubbish has managed to get under the screen, then the glass can also be lifted and the mote removed using the adhesive side of the adhesive tape.

The modern market offers each buyer a huge amount different models gadgets, smartphones and other similar devices. Despite the fact that the display is made reliably, the buyer decides to extend its service life by purchasing a protective glass. This is due to the fact that after a while we do not treat smartphones as carefully as at the first stage. Today we will talk about how to clean the phone before sticking the glass, how to get rid of dirt, remove stains, how to clean the gasoline and rainbow stains, cut, wipe the protective glass from the inside and what tools we need for this.

What is protective glass?

Protective glass is a modern type of display coverage on smartphones and gadgets. It is made using a chemical method based on tempered glass.

Important! Compared to ordinary film, it is several times thicker and harder. That is why, if this coating is present on the phone, it protects the screen from fingerprints, scratches, moisture and even bumps. Despite these characteristics, the brightness and color does not change.

Due to the multi-layer coating, the thickness of the glass varies from 0.25 mm to 0.5 mm, the composition of which is as follows:

• The first layer is always made on the basis of silicone. It sticks to the display.
• The next layer is the bonding layer. It is he who does not allow the fragments to spread if a crack or mechanical shock occurs.
• The third layer of coating is an anti-reflective film. It keeps patterns visible on the screen when it is exposed to direct sunlight or other bright light.
• The protective layer protects against bumps, falls and other mechanical damage.
• The very last layer is an oleophobic coating. It provides protection from moisture, fingerprints and makes it easy to clean the screen.

With active use, the top coating, which ensures the reliability of the unit, becomes dirty. It was then that the question arises of how to clean the protective glass of the phone. How to do this and what is required for this, we will consider further.

Immediately pay attention to the state of the back of your gadget. You may need information on how to remove scratches from the phone case.

What is a protective film?

Protective film appeared on smartphones for a long time. It is not a high-tech product and is present on every gadget. This product is characterized by the presence of three layers:

• the bottom one sticks to the screen;
• medium absorbs ultraviolet radiation and provides brightness when exposed to bright light;
• top - is responsible for protecting the display screen.

Important! The most important thing for a film is proper gluing. To do this, you need to have a little skill, since the first time it can not always work out.

All protective films that are present on the market of smartphones and gadgets are divided into three types: matte, glossy and mirror. Let's take a closer look at each type to understand if there will be a difference in cleaning:

• The matte film absorbs glare and also hides fingerprints. The main disadvantage is that it degrades the image quality. However, its cost is very low. Many craftsmen classify such a film as a technological one and advise not to stop the final choice on this product.
• Glossy protective film is the most popular among similar products. The main disadvantage of such a coating is that it is easily damaged. The film strongly reflects light, scratches and other quickly appear on it. mechanical damage. Fingerprints are also visible.
• Mirror film is the least popular among similar products. The peculiarity lies in the fact that when the screen is off, it can mirror the image. However, the quality and brightness of the screen changes when this coating is pasted - this is the main drawback.

All of the above films get dirty, and this is especially noticeable when dust gets under the coating. How to clean the film for the phone, we will now analyze.

How to clean the protective glass on the phone?

If you are thinking about how to clean a phone film, then ordinary adhesive tape, or, as it is also called, adhesive tape, will help you. For this you need:

• take a wide adhesive tape;
• cut off a piece of about 30-40 cm from it;
• stick it to the surface so that the sticky side is on top.

After that, it is worth sticking the protective film with the sticky side to the adhesive tape. Then very carefully and slowly immediately peel off the film. All the dust that was present on the product will go away, and the sticky layer will remain.

Important! If you need to remove scratches from the top of the protection, then polish the defects with felt, a soft cloth, or with the help of auxiliary means - white toothpaste, GOI paste or olive oil.

Another way to clean the protective glass from the inside is to use water and soap. For this:

• You need to remove the contaminated product from your phone.
• Wash off all dust particles in hot water.

• After carrying out this procedure, it is very good to lather the sticky layer with soap. For this, it is better to use two or three layers.
• After that, take and wash off the soapy solution under water. See that the water is glass from the film.
• Then we glue the film onto the cleaned wet display using an ordinary credit card.
• We look so that air bubbles and other villi do not get in.

If all else fails, The best way to restore the attractiveness of your gadget is to replace the protective part. On our website you will find detailed instructions About,
