The main function of a protective glass in a smartphone is to take a hit. This provides protection for the touchscreen from damage. Protective glass often becomes unusable after being hit. It is covered with cracks, chips and other damage. As a result, the level of protection drops significantly. The view of the display deteriorates, and the smartphone itself loses its attractiveness. To replace the cover with a new one, let's look at the features of how to remove the protective glass from the phone.

Precautionary measures

Before you remove the protective glass from the phone, you need to take into account a rather important point. Due to the fact that the touch screen has a perfectly smooth surface, the glass adheres very strongly to it. Often it is held not by glue, but by electrostatic forces. This is how two flat surfaces touch, and it will not work to remove the glass by simply prying it with a fingernail. If you use the first tool that comes across, for example, a knife, then there is a risk of damage to the case and display of the smartphone.

It is not enough to use one silicone suction cup. If it is strongly glued to damaged glass, then a vacuum will not form under it, and when force is applied, it will come off. With a good grip, the suction cup will not come off, but another problem will appear. The sensor in the housing is fixed using glue or double-sided adhesive tape. Their tensile strength is lower than that of protective glass and touchscreen. If you overdo it, you can completely disrupt the screen module, damaging its cables. It is necessary to act consistently and deliberately.

Removing the glass from the phone

Before you remove the cracked protective glass of the phone, you need to prepare and arm yourself with a special tool kit.

We will need:

• Lint-free wipe.
• Medical gloves are optional.
• Silicone suction cup is optional.
• Glass cleaner (preferably containing alcohol), vodka, alcohol or alcohol perfume (cologne, perfume) - to choose from.
• A thin plastic stick, spatula or plectrum.

Often protective glass is completed with the necessary devices.

Consider how to remove the old phone film:

• Before removing the protective glass from the phone, you need to wash your hands with soap and dry. Otherwise, rubber gloves are worn. This is required to prevent streaks and fingerprints from appearing on the screen surface.
• To replace the protective glass on the phone, you need to find the most complete corner where there are no chips and other damage (or they are, but in the smallest amount). There it is necessary to cling to the suction cup, at the same time pressing it against the screen.
• The mediator is attached to the corner where the suction cup is glued. This is necessary to peel off the edge of the glass. At the same time, you need to slightly pull the suction cup towards you. It is important not to overdo it here so that the screen is not torn off until a gap forms between the glass and it. If there is no suction cup at hand, then it will be enough to smoothly insert the mediator deeper into the resulting gap.
• As the broken protective glass peels off, you need to deepen the card / spatula / pick. If the screen is large, then you need to work with two tools at once. They should be promoted in different directions.
• The final touch in replacing the screen protector on your phone is to pull the suction cup towards you until the glass is completely torn off. You can take the edge with your fingers and do the same.

Gluing new glass

For high-quality replacement of the protective glass on the phone, all procedures should be done in a clean room where there is no dust.

• When you have already figured out how to remove the protective glass from the phone, and have completed this action, we proceed to sticking a new one. We clean the screen with an alcohol-containing liquid.
• From the new protective glass, remove the film from the side that is attached directly to the phone. The glass should be kept as close to the surface of the gadget as possible. Align it carefully and make sure all holes match. After that, the glass is completely lowered onto the screen.
• If bubbles appear, they are easily displaced after swiping the glass with a dry cloth. The last step is to remove the second film. Now your phone is protected.

Removing and sticking the protective glass is very simple. To perform this process, you do not need to contact service centers, everything is quickly done by hand.

The main function of the protective glass of a smartphone is to take a hit on itself, protecting the touchscreen from damage. When this happens, it often falls into disrepair, becoming covered with chips, cracks and other damage. The level of protection against this drops significantly, in addition, the view of the display worsens, and the smartphone loses its attractiveness. To change the coating to a new one, you must first remove the broken protective glass from the phone. And here there are difficulties, which will be discussed in the material.

Precautionary measures

It is necessary to take into account one important point before removing the old protective glass from the phone. Thanks to the perfectly smooth surface of the touch screen, the glass sticks to it very firmly. Usually it is held not by glue (although this happens), but by electrostatic forces. The two flat surfaces are very firmly in contact, making it impossible to remove the glass by simply prying it with a fingernail. If you take the first available tool (like a knife) - there is a risk of damaging the smartphone display and its body.

One silicone suction cup is also not enough. If you stick to a badly damaged glass, a vacuum does not form under it inside, and when force is applied, it will come off. If the grip is good, the suction cup will not come off, but another problem arises. The sensor is fixed in the housing using double-sided adhesive tape or glue, the tear strength of which is lower than that of the touchscreen and protective glass. Overdoing it, you can rip off the screen module completely, damaging its cables. Therefore, it is necessary to act deliberately and consistently.

How to remove the glass from the phone and stick a new one

Before you remove the broken protective glass from the phone and replace it, you need to prepare and arm yourself with a set of tools and tools.

This will require:

• mediator, spatula or thin plastic card (preferably 2 pieces);
• silicone suction cup optional;
• lint-free napkin;
• glass cleaner (preferably alcohol-containing), alcohol, vodka, or alcohol-based perfume (perfume, cologne) - to choose from;
• medical gloves - optional.

Quite often new protective glass can be completed with necessary adaptations.

The dismantling procedure is extremely simple and takes a minute.

• Before removing the protective glass from the phone, you need to wash your hands with soap and dry thoroughly, or just wear rubber gloves. This is to prevent fingerprints and streaks from appearing on the screen surface.
• On broken glass, you should find the most complete corner, where there are no chips or other damage (or there is, but in the smallest amount). There you need to cling to the suction cup, pressing it to the screen.
• The corner to which the suction cup is glued must be pryed off with a pick, spatula or suction cup so that the edge of the glass peels off. To do this, at the same time slightly pull the suction cup towards you. It is important not to overdo it so as not to rip off the screen before a gap forms between it and the glass! If there is no suction cup at hand, you can simply smoothly insert the mediator deeper into the resulting gap.
• As the glass peels off, the mediator / spatula / card should be deepened. If the screen is large, it is recommended to work with two tools at once, moving them in different directions.
• The final touch is to pull the suction cup towards you until the glass is completely torn off. You can take the edge with your fingers and do the same.

There are several ways to remove tempered glass from your phone screen. The one you need to use will depend on how well the glass is attached to the display. Before you start removing the protective glass from the smartphone screen, it is worth warming up the screen for about 15 seconds at a low air temperature. It should slightly melt the adhesive on the protective glass. It is important not to overdo it by bringing the hair dryer nozzle too close as this can damage the screen. After that, you can just use your fingers or some flat thing that will help make a gap between the screen and the protective glass. The last step will be the careful removal of the glass.

First, you can try to remove the protective glass with your own fingers, without using improvised means. Perhaps it was fixed weakly enough, which would allow this operation to be done without effort. You just need to try to hook the edge of the glass with your fingernail. This should be done on the side that is least affected by cracks or chips.

If the protective surface easily succumbed to this effect, and moved away from the screen at least on one side, then you can continue to remove it. As soon as it starts to rise, you need to move further under the protective film with your fingers, and not remove it in one jerk. This will help prevent cracking. This should be done slowly and evenly, otherwise many glass fragments may form.

If the protective glass is not easy to remove, then you can try using a toothpick to pry off one of the corners. As soon as you manage to lift the corner of the glass up, you need to pull it with your fingers, as in the previous method, slowly and evenly. In addition to a toothpick, you can use a credit card, a piece of thin cardboard, or any flat item. You just need to insert the existing thing into the gap between the screen and the glass, and then slowly press it to lift the protective glass from the display.

Installing a new protective glass on the smartphone screen

There are two ways to install a protective glass on the smartphone screen. They provide for dry installation of glass and wet, respectively. The first method is for protection with tempered glass, which does not come with a special solution.

First you need to clean your phone screen with a lint-free microfiber cloth. Then you need to detach the glass from the sticky side from the factory protective film. After that, you need to carefully attach the protective glass to the screen, making sure that the Home button, speaker and camera holes are located exactly in their places. You can use a credit card or any other tool to ensure even coverage and prevent bubbles.

Wet mounting is designed to be protected by tempered glass, which comes with a spray bottle (usually containing alcohol) to aid in installation. Some people prefer to apply protective films and glasses in this way, since this method completely prevents the penetration of dust and fine hairs. Then you should repeat all the steps from the previous method.

Phones often fall, glass, as the most fragile part, beats first. It would seem that there is no problem to go to replace the glass on the phone, but in practice everything is not so simple.

Previously, the glass on the phone was changed separately, and the glasses cost a penny. They are still inexpensive, but with the advent of the era of touch phones, the procedure for replacing glass has become much more complicated. What is the price of replacing the glass on the phone, taking into account the work?

If you have a touchscreen phone and the glass on it is broken and needs to be replaced, then you need to know the following:

Modern touchscreen phones are of two types: those phones in which the sensor is connected to the glass, changing the glass accordingly, you change the sensor, and the cost of touchscreen glasses is already much higher, since in addition to the glass itself, there is also a touch panel with a cable that has a connector to the phone's motherboard. And yet, replacing the touch glass is not as expensive as the cost of replacing the actual glass on more expensive models.

The most advanced phone models, flagship companies such as Iphone 4, Iphone 5, Samsung Galaxy S3, Galaxy S4, HTC One, Nokia Lumia 920, Sony Xperia Z and others, have a more complex screen design: the phone screen consists of an LCD display, which in fact, it transmits the image, the sensor (touchscreen), which is responsible for pressing, and the glass, which is protective and decorative. At the same time, the screen module is solid, the components are glued together in an industrial way, and according to the manufacturer's instructions, the screen is changed entirely.

glass replacement procedure.

However, the glass can still be changed. The procedure for replacing glass on phones of top models is as follows: the display module is heated with a special hair dryer or a special heating pad, the glue with which the glass is glued to the sensor is softened, then with a knife, a thin spatula, a plastic playing card, a special molybdenum wire and similar devices, the glass is disconnected from the screen. Then the adhesive residues are removed using a special solvent, scraper, napkins, soft cloth, etc. The new glass is placed either on double-sided tape or on special UV glue (similar to the factory one).

In the description it looks quite simple, but in practice everything is far from it.

Firstly, it is extremely difficult to achieve uniform heating of the surface of the display module, there is a danger of overheating the display and sensor, after which either the image will disappear or the sensor will not work correctly. This can manifest itself both immediately and after some time.

Secondly, it is possible to remove the glass without problems only if there are one or two large cracks on the glass, but in the case when there is a web of small cracks on the glass, the glass will crumble, and it is easy to damage the sensor with fragments, as a result, you still have to change display module as a whole. Also, from the impact, there may already be microcracks in the display, which do not manifest themselves before the procedure, but when heated and / or pressure on the glass can lead to failure of the LCD display itself.

Thirdly, cleaning the sensor from glue is also not useful for the phone, the glue is removed with a scraper, cloth, etc., the sensor is seriously affected, which can also lead to its failure.

And finally, in most cases, the craftsmen put the new glass on a double-sided adhesive tape glued around the perimeter of the screen, it is impossible to ensure a snug fit of the new glass, over time dust will accumulate under it, and the adhesive tape itself can move away.

Not everyone knows how to put new glass on glue, not only special glue is required, preferably German, but also an ultraviolet lamp (the principle of glue hardening is like in a dental office when a photopolymer filling is placed), and it is desirable to have special equipment for the display and glass to provide 100 % exact hit of the glass in its place.

The work of glass replacement takes up to three hours, it is extremely painstaking and requires a very high qualification of the master. At the same time, if something does not work out, then the master is also responsible for this, it is impossible to explain something to most clients. No guarantees can be given for the successful outcome of the operation.

That is why most professional workshops will tell you that the glass does not change and will offer to replace the entire display module. Of course, you can find a master or a service where they will take it on, but be sure that the glasses are changed there in an amateur way, the probability of success is 50/50, the probability of further performance and preservation of the appearance of the phone is even lower.

Protective glass is a special coating made of high-strength chemical glass, which is resistant to mechanical damage, scratches and chips. By installing additional protection on the screen of your iPhone, you will protect the display from possible shocks, thereby extending its service life.

Protective glass features

Comparing protective glass and film, there are a huge number of advantages on the side of the glass coating.

• with a thickness of only 0.25 mm, a high level of strength;
• special oleophobic coating eliminates the appearance of fingerprints and other fatty contaminants;
• many types of glass have a nano-coating, thanks to which the smoothness of the glass prevails even in front of a conventional display;
• the glass is attached to the screen using a silicone base - shifts and air bubbles are excluded;

Among the varieties of protective flexible glasses, there are models with hemmed edges and without. In the first case, the edges of the protective coating are rounded, which makes the glass almost invisible, and the edges of the glass do not crumble upon impact.

How to remove the protective glass?

Despite the fact that the life of the protective glass is many times longer than the life of the film, there comes a time when the coating needs to be changed. The silicone-based glass is firmly in contact with the main display, so it will take some skill to remove the protection.

Tools required to remove the protective glass:

1. Microfiber cloth (small).
2. Strong floss or special floss for cleaning teeth.
3. Needle.

The process of removing the film itself is not complicated, but you need to be as careful as possible, otherwise the flexible glass will constantly stick again.

Under one of the edges that are more convenient for work, pry the thread. To do this, carefully move the edge of the glass with a sharp needle and immediately place a napkin so that the base does not stick again. For convenience, it is better to remove the glass with a partner, you will be able to remove the old protective coating more quickly and efficiently.

It is worth noting that this number of tools is designed to remove undamaged glass. But if the surface is split, then more painstaking work and additional items are required. If you are afraid to remove damaged glass yourself or do not have work experience, contact the professionals. The company that repairs Apple equipment in Nizhny Novgorod "MakeMeApple" will help you with this. You can leave a request using the website or by calling the phone.
