How to apply bubble and dust-free protective glass

Solving Potential Problems

There are several problems that arise after the work has been done. They can be eliminated at home without much effort. The glue under the glass will not always be evenly distributed - streaks will remain on the screen, the corners of the surface will peel off, and air bubbles will enter.

In this case, it must be glued or re-glued. It is more difficult to re-glue it again, at the initial stage they try to hide the flaws. They buy an adhesive liquid, if there is no money for it, glycerin or vegetable oil will do. Wipe the glass surface with a rag with alcohol, apply adhesive with excess. Smooth the surface with a plastic card.

Important! Do not sharply lift the protective glass from the surface, this may damage the sensor

How to stick the bubble-free protective layer

In order to glue bulletproof glass yourself at home, you need to familiarize yourself with how to do it correctly.

Workplace preparation

First, it is necessary to carry out preliminary preparation of the premises in which the work will be carried out. It is necessary to get rid of the dust so that it does not stick to the protective coating. In this case, it is better to carry out wet cleaning using a spray bottle so that the dust gets wet and falls to the floor. When cleaning, they wipe not only the surface of tables and furniture, but also the floor covering.

We prepare the necessary tools

Having finished cleaning the working area, they begin to prepare the tools that will be used when gluing the glass. In addition to bulletproof glass and a smartphone, you will need:

Scotch;
microfiber cloth for wiping the glass surface;
plastic card;
alcohol, antiseptic or other solution to degrease the screen.

Degrease the screen surface

In order for the protective coating to adhere reliably, the surface of the smartphone screen is degreased

When degreasing, the napkin is moistened in an antiseptic, after which the display is gently wiped with it. After that, the wiped surface should not be touched with fingers.

Removing dust particles

Sometimes dust particles fall under protective bulletproof glass. To get rid of them, you will have to lift the glass with clerical tape, get rid of the dust and re-glue it.

What are the pros and cons of protective glass

Manufacturers are improving the material for the manufacture of screens, but with an accidental impact, even the best glass will not withstand the load and will crack. Replacing the display will cost 30-50% of the cost of a smartphone. It is cheaper to stick a high-quality protective glass, however, it should be remembered that such protection does not give a 100% guarantee.

pros

Undoubted advantages of protective glass:

softens the impact on the asphalt flat;
in most cases, with a strong impact, only the top layer cracks, the screen remains intact or with minimal cracks;
there are options on sale for displays with 2.5V and 3D technology.

Replacing the glass will cost ten times less than the screen.

Minuses

Several disadvantages of protective glass:

a wide selection is presented only for flagships and popular models;
owners of new products have to wait 1-2 months for glass to appear on sale;
If the cover is fitted with high precision, due to the thickness of the glass, it may not close.

Protection does not save the phone from falling down.

Replacing the protective glass on a smartphone - two ways

Follow the steps described here and you will understand how to apply a protective glass at home to your phone or tablet. There are two main ways: The first is the simplest, but requires some skill, and the second is suitable for everyone, but requires the utmost care. To consolidate the material, I recommend watching the video after reading it.

The first method: cut a small piece of tape and glue it to the front surface of the protective glass so that you can grip it with your fingers. Clean the screen again so that there are no small dust particles left, then holding the glass by a piece of adhesive tape, we bring it to the screen of a smartphone or tablet. Without turning the glass over, peel off the protective film and align it so that there are no distortions, we attach it to the screen. I repeat, do not turn the glass over, the adhesive base will instantly collect all the dust around.

Now you just need to just touch the center of the screen of your smartphone or tablet and that's it. Right in front of your eyes, the glass is fixed as it should, we check how the display reacts to touches. If everything was done correctly, you do not have to remove it and remove dust at the risk of damaging the glass.

Everything is clear without words, we press in the center.

The second method: it is less popular and a little more complicated, but relatively simple to perform. Place the glass on the smartphone screen, align it and secure with three pieces of adhesive tape or stickers. Glue one piece at the bottom, the second at the top and the third in the middle. Subsequently, we will get a kind of door that should be easy to open and close. Now wipe the smartphone screen with fine dust again.

Detach the film and cover the phone screen with a protective glass. We check how the phone reacts to touches and if there are no dust particles under the glass, then you have done an excellent job.

Watch an educational video showing how to glue glass to a smartphone

But for me, the second option caused a serious problem. A speck of dust got under the glass, being on the right edge, I didn't like it right away and I decided to get rid of it, let's describe how.

We prepare everything you need

Let's get ready. In addition to a smartphone, we will need: adhesive tape or stickers with an adhesive base, the protective glass itself and a set of cleaning wipes, as well as special stickers for removing dust particles, which are usually attached to a shockproof glass with an oleophobic coating.

There are two sets, it is better to take in reserve.

It seems to me that you have already prepared all this, and if not yet, then we order with free shipping on Aliexpress. I recommend learning about how to buy on Aliexpress, it is very profitable. There are good, inexpensive screen protectors for smartphones, tablets, and more. I recommend preparing a couple of glasses in reserve, because as the proverb says: "The first pancake is always lumpy."

We find a place where there is less dust and make ourselves comfortable

So, we should have two napkins in envelopes, but do not rush to open them. First, you need to find a well-ventilated place where there is no dust in the air, for example, near a window. We found a place, great, now, before gluing the protective glass, put the phone on a flat surface, best of all on a book, at home it will be easier and more convenient to do everything.

Make sure that everything you need is at hand and you can start replacing the glass. First, thoroughly clean the smartphone screen with the alcohol-soaked cloth supplied. Then wipe dry with a dry cloth from the kit, usually a deuce is drawn on the bag. Then remove the glass from the cover, but it is too early to peel off the transparent film.

Wipe the screen thoroughly with a napkin.

Preparation for work

To carry out the manipulation, the workplace is preliminarily prepared. In order for the glass to securely attach to the screen, a humid environment is necessary, it is recommended to work in the bathroom. In a dry environment, dust or dirt particles will get on the display and ruin the tablet's appearance.

Preparation rules:

Hot water is drawn in the bathroom to generate steam. You can take a shower.
Do not open doors during work.
Previously, a table or stool is brought into the room, sometimes a washing machine lid is used.
Wipe the display with a cloth, clean it from dirt.
Before starting work, wash your hands thoroughly with soap or wipe them with alcohol.
Tie your hair in a bun or wear a shower cap to keep it out of the cover.

Water vapor deposits fine dust particles on the floor and improves the adhesion of the screen and glass.

How to stick protective glass

The gluing process is simple, the most important thing is the preparation of the room and care. Unlike film, glass can be glued to a mobile phone several times

The protection is attached due to the adhesion of the materials, and not on the adhesive base.

Prepare your tools

Level the surface you will be working on and prepare everything you need:

microfiber napkin;
paper tape;
sharp scissors;
liquid for cleaning displays or alcohol;
plastic card.

Remove the old case from your phone and turn on bright lights to see the smallest air bubbles while gluing.

Preparing the screen surface for glass bonding

The set of protective glass includes two napkins. One is impregnated with alcohol to degrease the surface of the phone screen. Wipe the display thoroughly, then polish with a second microfiber cloth.

If the kit does not include a degreasing wipe, before sticking the protective glass on the phone, use tape to remove all dust and dirt from the surface. Cut a piece, stick on the screen and peel off, repeat 2-3 times.

Sticking protective glass

Without removing the film, first carefully try on the glass to the surface of the phone so that all the holes line up.

Cut off small pieces of tape and attach them alternately to the glass and back of your smartphone.
Check the coincidence of all the gaps several times by throwing back the glass and covering the screen with it, move the tape if necessary.
Once again, degrease your hands and the surface of the screen with a special liquid and polish, wait 4-5 minutes until it dries completely.
Peel off the protective film from the glass and carefully place it on the display. Smooth out all surfaces with a plastic card, squeezing air out to the edges.

When finished, remove the tape from back of the phone and glass surface.

Workplace preparation

This advice seems absurd to many. Before gluing the protective glass, it is necessary to do a wet cleaning of the room where the work will be carried out. This is necessary to remove dust from the room. All electrical appliances attract the smallest rubbish, and smartphones are no exception. This makes it difficult to apply the protective coating. Due to the settling of the smallest dust particles, invisible to the eye, the pile of animals, air bubbles are formed.

Before gluing the protective glass, we do wet cleaning of the room

If for some reason there is no time for cleaning, then at least ventilate the room. The most suitable for gluing is a bathroom or kitchen, where there is the least amount of dust.

Despite the possibility of fulfilling the previous recommendation, be sure to wipe the table with a damp cloth, on which all work will be carried out. It is advisable to dampen a cloth with water and detergent or antistatic agent. Be sure to wash your hands with soap, it will not hurt to wear thin medical gloves.

Advantages and disadvantages of protective glass

Bulletproof glass has a number of advantages and disadvantages, which it is better to familiarize yourself with before using it. Among the advantages of such protection are the following:

Versatility. A lot of universal bulletproof glasses are produced that are suitable for many models of modern smartphones.
Ease of use. It seems to many that it is difficult to install protection on a mobile phone, but it is not. Anyone can handle the installation of bulletproof glass.
Does not affect the image. High-quality models of protective glasses do not degrade the image quality of displays. Only cheap frosted glass can degrade the color rendition of the screen.
Durability

With careful use, bulletproof glasses serve for more than five years.
High level of protection.Thick glass protects smartphone displays from chips, scratches and cracks that appear after drops.

Bulletproof glasses have a significant drawback, due to which some people refuse to install them - the weight of the product. They make the phone heavier and more bulky.

Benefits of protective glass

The protective coating for touch technology has advantages over conventional films. These include:

strength;
crack protection;
the glass does not allow moisture to pass to the screen;
does not affect the operation of the sensor;
durability.

Technologies are developing more and more. Almost every user of a modern touch device encounters the problem of a broken screen. Protective glasses take on the force of impact, thanks to which the tablet remains unharmed.

Important! Changing the screen protector is cheaper than buying a new screen. It is especially suitable for protecting devices used by children.

Features of working with different models

When working with different models, the most important thing is to choose the right size for the film. There are several options for each model, with pre-drilled holes for the camera and microphone.

Iphone

There are a huge number of protective glasses for the iPhone on sale. The first thing to do when gluing is to remove the cover. This is forgotten by many users. It is not recommended to purchase covers intended for other models.

Xiaomi

For the Xiaomi model, there are also protective glasses of a suitable shape on sale, but during gluing, you should make sure in advance that the holes for the speaker, cameras and sensors completely match.

Meizu

Since the location of the camera in different Meizu models is different, you need to choose a glass that is suitable for a specific model. To avoid errors, a fitting is done before gluing.

Zte

High-quality glass for this model does not contain an adhesive layer and is fixed on the sides. Before applying it, you must also degrease the display, but if necessary, the glass can be removed and later returned to its place.

Samsung

Glass for Samsung phones can be completely transparent or with a black rim around the edges. To re-stick the protection on such a phone, sometimes it is enough just to remove the dirt.

Tips for choosing a safety glass

Having settled on this type of security, you should know that all glasses are tempered, but endowed with different properties. There are two types of screen protectors - glossy and matte.

In the first case, protection against scratches will be minimal, since the screen itself can easily get minor damage. This type of glass is glued to effectively resist drops and impacts, preventing damage to the touchscreen.

Frosted protective glass on iphone or other types of gadgets will have a higher degree of protection, up to anti-reflective coating. The negative side of such a purchase will be the high price, especially if you are purchasing a product of a well-known brand.

When choosing protection, focus on the package, the properties you need and reviews from other consumers. You can leave your own comment below, which will help other users of the site make the right choice based on personal experience.

Step-by-step instructions for gluing glass

First, the phone is removed from the case and disconnected. Then the old protective coating or glass is removed from the surface.

Sticking consists of the following stages:

Degrease the surface of the screen with a monitor cleaner, antistatic agent, or alcohol (no. 1 cloth included).
Dry the screen to a shine with a microfiber cloth (napkin No. 2 from the kit).
If dust particles remain on the surface after that, they are removed with tape.
The film is removed from the protective glass by pulling the tab.
Holding the protective cover at a distance of 1 cm from the screen, make a fitting: the speakers and buttons must match the corresponding holes.
Lower the glass onto the display.Since the surface is adhesive, the coating quickly bonds to the display.
If air bubbles appear under the glass, they try to remove them using microfiber or a plastic card. In both cases, they move from the center to the edges.

Glasses are more often produced for specific models of smartphones, less often - universal, designed for a certain diagonal display. But in the first and second cases, you must first give a fitting and determine exactly how the protective coating should be located on the smartphone.

If the phone to which the protective coating is glued has just been purchased, then it is not necessary to clean the display surface. You just need to remove the factory protective film from the screen.

Smooth placement of glass

Not everyone succeeds in gluing the glass smoothly the first time. Ordinary office tape will help to place it correctly. Then proceed as follows:

Scotch tape is glued to the back of the smartphone along the edge of the smartphone.
The excess tape is cut from above and below.
The glass is positioned exactly as it should be glued to the display, with the adhesive surface facing down.
With one hand they fix the glass on the smartphone, with the other they glue the tape to the protective coating.
The glass folds back like a cover in a book.

After the glass is locked in the correct position, the display can be cleaned. After gluing, as described above, the tape is removed.

Removing dust particles

If there is a speck between the surfaces, an air bubble forms around it. Only by smoothing with microfiber it cannot be removed. But the situation can still be remedied.

Dust removal process under protective glass

They do it like this:

Using a plastic card or adhesive tape glued to the coating, they lift the coating to the place where the speck of dust is.
A piece of scotch tape is glued to the monitor glass in the area of dust particles. Tear off the tape sharply.
Lower the protective cover into place.

Auxiliary means

To make the gluing of the protective glass more comfortable, you can find a gel for filling air bubbles on sale. They often form along the edge.

Such funds are available in two forms - in a sachet or in a pipette. The liquid is not afraid of temperature changes, so it will not freeze even in frost. One sachet is enough for several uses.

Gel for filling air bubbles that form after gluing a protective glass to a smartphone

The gels are used as follows:

Open the pipette. They are smeared with liquid along the edges, where the glass recedes.
Allow the device to lie down so that the liquid spreads under the protective cover.
The remnants of the product are removed with a dry napkin.

The thinner the applied bond gel, the better the result.

What kind of protective glasses are

To stick a protective glass on your phone, you first need to choose the right option. Manufacturers offer several types of glass, differing in functionality.

Full Screen

It is produced specifically for models of phones with 2.5D screens, completely covers the surface and has a colored frame on the edges. The adhesive layer is located around the perimeter.

Oleophobic coated

When using the phone in bright sunlight, glare appears on the screen and distorts the image. The oleophobic coating prevents the appearance of reflections, it is convenient to use the smartphone even at the beach. The second function is protection from greasy stains.

Universal

Standard glass for smartphones with a screen diagonal of 3 inches. A budget option to protect your phone without a case.

Matte and glossy

The frosted protective glass is suitable for using the smartphone in bright sunlight. Increases the graininess of the image and makes the picture slightly darker. Glossy glass is suitable for use in all conditions.

2.5D glass

The top edge is rounded at the edges at an angle of 45 degrees. When using the phone, your finger will not be cut on the sharp edges of the glass. Now all manufacturers use this technology for the convenience of users.

5D glass

It has a dome shape and maximum adhesion to the screen surface. Distinguish between expensive options with a bend at the edges and cheap ones without bending.

How to stick protective glass

Step 1. Prepare the room

If dust gets under the glass, you have to live with bubbles on the gadget screen or try to remove them. To avoid this, do a wet cleaning in the room, or at least ventilate the room with a clean cloth, preferably with detergent, wipe the table where you are going to glue the protection, wash your hands.

Another option: to carry out all the manipulations in the bathroom. In this case, the procedure is as follows:

Turn on hot water for a few minutes, or better take a shower.
The resulting steam will bind all the dust, it will settle to the floor, and the room will become almost sterile.
Lay on a towel and sprinkle it with water from a spray bottle to be sure.

Step 2. Prepare the tools

stux

In addition to the device and protective glass, you will need:

Liquid for cleaning displays, antistatic agent, or regular alcohol.
Microfiber cloth.
Stationery tape.
Scissors.
Plastic card or scraper.

Step 3. Try on and align the protective glass

Make sure that all holes and cutouts are perfectly aligned. This is done like this:

Apply the protector to the smartphone with the correct side.
Try on so that all the gaps along the contour are the same.
Stick two or three strips of tape 3-4 centimeters long on the glass at one of the side edges.
Attach the loose ends of the adhesive tape to the back of your smartphone.
It should look like a drop-down book.

Step 4. Degrease the screen surface

This will remove dirt and streaks that can ruin the entire result. Proceed like this:

Use the supplied damp cloth, or spray the screen with display cleaner, antistatic agent, or alcohol.
Wipe thoroughly to remove any remnants of old film glue and other possible contamination.
Use a microfiber cloth to wipe the screen dry.

Step 5. Make sure there is no dust

To be sure to play it safe and collect any dust particles from the surface of the screen, use a special sticker from the kit, a strip of adhesive tape or electrical tape. Just stick and peel them all over the display area.

Step 6. Apply protective glass

Compared to the previous ones, the final step is the easiest. Here's what you need to do:

Lift the glass so that it stands upright.
Carefully peel off the bottom protective layer from it.
Quickly lower the glass onto your smartphone. Due to the fasteners made of adhesive tape strips, it will fit perfectly.
Smooth out air bubbles from the center to the outside with a tissue or card.
Remove the adhesive tape from the glass and back panel.

How to re-glue at home

If the glass was glued several minutes or seconds ago, it can be quickly torn off and reapplied, then it will lie flat. However, if dust and hair are clogged, you will have to clean the surface before sticking back.

What is needed

To update the phone surface at home you will need:

Scotch;
hairdryer;
degreasing napkin.

This is enough to remove the protective cover and clean it from dirt.

Preparing the workplace

To prevent more dust from adhering to the glass during operation, you must first prepare the room. If this is not done, all dust will settle on the screen and the film will become covered with bubbles.

Even a small amount of dust falling under the glass can spoil its appearance and create unevenness.

How to glue correctly

The usual instructions for gluing glass to the phone are not suitable in this case, since you need to carefully prepare not only the screen, but also the film itself, otherwise it will lie unevenly or remain dirty.

Removing the glass

To prevent the glass from cracking, it must be removed correctly

It is important to distribute the load over the entire surface, removing it from the two upper corners and moving to the lower ones.Removing glass may not be as easy as it seems at first glance.

The glass is thicker than regular film and may break. To prevent this from happening, you need to pry its edge with a plastic card or tape from two corners, and slowly move to the other edge.

It is not recommended to use sharp objects, as not only the protective coating, but also the phone can be scratched.

Removing dust

To remove dust from the screen, you need to use a special microfiber cloth. If there is none, a regular wet wipe will do, but after that you need to additionally use a regular dry cloth.

Degreasing the screen

A simple way to degrease the screen:

Primary treatment with special liquid for screens, alcohol or antistatic agent.
Then you need to wipe the phone with a dry cloth and assess its cleanliness. Not a single stain should remain. Wipe the screen again if necessary.
The phone is placed on the table without touching the screen with your fingers.

Immediately after degreasing, you need to start gluing in order to prevent contamination.

Re-sticking

It is much more difficult to glue the glass a second time than a regular protective film. It is necessary to completely remove and clean it, and only then re-stick it, leveling the contour.

Re-gluing instructions:

If there is a case on the phone, it is removed, and then, using a spatula, card or tape, peel off the glass. You can also use a silicone suction cup while lifting the edges with a plastic card.
The display should be thoroughly cleaned with a lint-free cloth and treated with an alcohol solution, and then additionally wiped with a microfiber cloth. Even a small speck of dust left under the glass can disrupt the operation of the touchpad, and then the phone itself will have to be changed.
The removed film is moistened in warm water, lightly rubbing the surface to remove dirt. You can also use an alcohol pad if the dirt is not heavy.
Then the glass is dried well under a cold stream of air from a hair dryer and is compatible with a smartphone, applied to the screen. If there is still glue on the surface, the glass will adhere with light pressure.

This procedure becomes completely impossible if the adhesive has been erased from the inside of the glass. Formic alcohol can be used for partial recovery and cleansing.

Varieties

Tablet covers are different. Time does not stand still, manufacturing technologies differ. They differ in strength, shape and degree of attachment.

2D

They have the shape of a rectangle, they cover only the front surface of the screen. A small gap of 1 mm wide remains at the edges. In connection with the invention, more durable variants are practically not produced.

2.5D

The straight glass has cutouts for the tablet speakers and the front camera, the edges are rounded. Not suitable for all models, as there are sensor systems curved at the edges. Protective coatings may bulge slightly outward, thereby allowing air bubbles to enter.

3D

Suitable for modern gadgets that have a curved screen. The design fits snugly to the sensor, completely repeats all the bends, almost invisible on the tablet. The coating does not allow air bubbles to pass through, does not leave streaks. Reliably protects the screen from shocks and drops.

4D

They have a dense structure, fit perfectly on the surface of the screen, repeat all the bends. For production, a dense material is used. The coating does not affect the operation of the sensor, it is practically invisible. It has been performing its function for many years.
