How to stick protective glass on a smartphone. How to apply a protective glass to your iPhone yourself

Numerous “smart” gadgets occupy an important place in the life of every modern person. The most common and popular among them are smartphones. Despite the many advantages of such devices, all models have a common drawback - a fragile screen. To protect your phone's screen from scratches, cracks and other mechanical damage that may occur from a fall or simply from careless handling, you need to glue special glass onto it.

To glue protective glass on your smartphone, you don’t have to go to specialized salons. Everyone can do this on their own using the step-by-step instructions below.

Preparation of materials and tools

First of all, you will need the smartphone itself and protective glass. In showrooms, you can choose such an accessory only for popular models; everyone else will have to be content with protective films or look for suitable glass in online stores.

The purchase of the accessory itself must be taken as responsibly as possible. Also in the cabin, you need to check whether the holes for the speakers and the camera match. For normal operation, glass models of medium thickness are suitable.

In addition to the glass and the gluing gadget itself, you will need:

Scraper (it can be replaced with a regular hard plastic card);
Sharp scissors;
Scotch tape (it is better to take both wide and narrow) - it is recommended to buy not construction or colored tape, but the most ordinary transparent one so that there are no marks left on the screen;
A microfiber cloth or cloth (you can use the one you use to wipe glasses);
Ethyl alcohol / antistatic compound or special liquid for cleaning the display.

There is no need to buy glue - protective glasses for smartphones have an adhesive inner surface, so they are securely fixed to the surface of the screen without the use of additional compounds.

Preparation of the workplace

When gluing the protection, it is important that no dust, dirt or moisture gets under the glass. Therefore, it is better to carry out the procedure in a clean room (it is advisable to pre-ventilate the room).

The surface on which you plan to glue the glass also needs to be cleaned. To do this, just wipe it with a clean cloth soaked in detergent, and then wipe it dry again with a napkin.

Before starting work, be sure to wash your hands.

Step 3. Degreasing the surface

This stage is very important. If you do not properly degrease the screen, you will not be able to securely attach the protective glass. Degreasing is carried out as follows:

Gluing protective glass

The accessory must be picked up and inspected again for chips, scratches, cracks and other flaws. If no damage is found, you can begin gluing.

On one side of the protective glass there is a special film. It must be carefully removed, holding the glass with your fingertips along the edges. Do not touch the front or back surfaces of the glass with your hands - there will be clearly visible fingerprints that will be difficult to get rid of.

Then the protective glass must be placed strictly above the gadget’s screen, without touching it (at a height of 0.5-1 cm). The accessory is aligned so that the slots for the speakers, camera and Home button (if present) coincide with their location on the front surface of the device.

After this, the glass is carefully lowered onto the surface of the screen. Since it has an adhesive surface, it will attach to the gadget itself.

Important nuances

For many iPhone models, developers offer ultra-thin glass with soft edges; when gluing them, you should not make any effort or somehow stretch the protective coating, so as not to accidentally change its shape.

If you fail to glue the accessory perfectly on the first try, there is no need to get upset or panic. As a rule, few people manage to cope with such “jewelry” work right away.

If there are small air bubbles left under the glass, a dry microfiber cloth will help to deal with them. You need to gently press on the screen and push the air out from under the glass.

Even if you follow all the rules listed above, small dust particles may remain between the accessory and the surface of the phone screen. Then a microfiber cloth will be powerless. The protective covering will have to be lifted. To do this, you will need a scraper or a card made of hard plastic.

You need to pick up the edge of the glass and lift it a little (you don’t need to peel off the accessory completely), so that you can “pick up” a speck of dust. A narrow strip of transparent tape is glued onto it. Then the adhesive tape is torn off with a sharp, confident movement, and a speck of dust remains on the tape.

All that remains is to simply return the edge of the glass to its place and wipe the screen again with microfiber.

If we are talking about a phone with rounded edges, there will be no fundamental differences in the technology for gluing the protective glass. All procedures are carried out in the same way as if the protective coating were simply rectangular. The main thing is to pay attention to the shape of the accessory when choosing – it should match the outline of the gadget.

The developers of the accessories carefully thought through all the details so that gluing could be done quickly, and the procedure itself turned out to be as simple and understandable as possible. If you do everything correctly, it will take about 10-15 minutes to glue the protective glass.

Protective glass. What and why?

The main purpose of protective glass is to protect the smartphone screen and reduce the likelihood of damage. A good safety glass is a multi-layer design that includes a polymer that resists scratches and light impacts, and a thin layer of real tempered glass. Nillkin and DiGi protective glasses use a high-quality layer of Japanese tempered glass Asahi Glass.

A layer of tempered glass allows you to redistribute the impact impulse in case of a strong fall. It is the presence of this component that explains the “cobweb” when the protective glass breaks.
Whether to use protective glass or not is up to everyone to decide.

But, given the cost of replacing the display and the difficulty of finding original spare parts (in the case of the iPhone), purchasing a protective glass becomes one of the very first steps to protect your smartphone.

What is a 2.5D screen?

Smartphones with slightly convex screens have been appearing for a long time, although it still seems like it was just a couple of years ago.

This effect is achieved by rounding the edges of a flat "2D" display in the Z axis. This effect can be more or less extreme, depending on how much curved edges are required. Even a slight curve can be used to make the edges of the glass feel smoother, while a larger curve will make the device look more stylish.

2.5D glass is produced in much the same way as flat glass panels, only with additional shaping when it comes to cutting the glass to the desired size.

The advantages of 2.5D glass are purely ergonomic and aesthetic.

2.5D screen and protective glass.

The 2.5D screen is beautiful, convenient and stylish. But, unfortunately, it does not add strength to the smartphone display and does not eliminate the need to use protective glass.

Unfortunately, a number of difficulties arise here.

The specificity of the rounded edges does not make it possible to make protective glass over the entire display and leaves the edge unprotected.

For many display manufacturers, physical rounding begins on the visible part of the display. And although it is not visible, it is precisely this that does not allow the protective glass to be properly glued.

As a result, if you glue protective glass onto such a display, the edges of the glass will hang in the air and will not stick.

This specificity is not a defect, which must be communicated to the end buyer before gluing the glass!

Options for solving the problem

There are only 4 basic solutions to the problem of gluing glass to a 2.5D screen:

1. Many manufacturers make protective glass in smaller sizes.
The advantage is that this glass is completely adjacent to the screen.
A noticeable disadvantage is that the glass does not cover the entire visible area of the display.

2. The second solution is also very popular and can often be found in high-quality glass. The glass is made to the largest possible size, down to the perceptible rounding area. The main advantage is that the glass completely covers the display. It is easy to use and when the screen is on, the area that is not taped is practically invisible. The downside is that the edges of the glass are not glued and this effect is noticeable when the screen is turned off.

3. Full Cover and Full Cover 3D protective glasses are made for Apple iPhone, which have painted frames around the display. The glass is glued to the entire screen. The protective frame perfectly follows the shape of the smartphone and completely protects the screen.
In the South-Contract catalog this type is represented by the following models:
DIGI Glass Screen (3D Silicone Edge) for iPhone 6/6s,
DIGI Glass Screen (Full Cover) for iPhone 7 and 7 Plus,
NILLKIN Glass Screen (AP+) for iPhone 6/6s and 6/6s Plus, iPhone 7 and 7 Plus.

4. Unfortunately, protective glass manufacturers produce this type of glass only for iPhone. For many popular positions on Android, there is Full Cover glass, but made using a different technology. Externally, it is very similar to Full Cover for iPhone, but there is no adhesive layer on the visible part of the display.

The glass is glued only along the perimeter and is held along the edge. This negatively affects the touch responsiveness of the display. In addition, the glass peels off very easily and dust gets underneath it. Due to the specifics of the design and the large percentage of negative reviews from end users, this type of glass is not included in the Yug-Kontrakt product range.

Replacing your screen protector can be a simple matter if you follow a few guidelines and use the right tools, otherwise you'll end up with an uneven, blistered finish.

First you need to carefully remove the old glass. It is important to remember here that the glass is attached to the screen not with glue, but due to static. And all attempts to tamper with it in any way will end in scratches on the case and display.

A special suction cup can be either a helper or your nightmare. If you use Velcro incorrectly, you can damage the sensor, cables and screen module. You need to act smoothly and carefully.

To install glass you need to prepare:

plastic card or mediator - it’s better to take 2 pieces;
a silicone suction cup (if you replaced the glass, you can do without it);
napkin or lint-free cloth;
alcohol glass cleaner;
rubber medical gloves.

If all of the above is present, replacing the protective glass will not take much time.

Step by step work

Before work, you need to make sure that there is no dust, lint or hair on your fingers, or it is better to just wear thin gloves.

Then install a special suction cup on the part of the screen that is less damaged. It needs to be pressed down and glued to the corner of the screen. Taking a plastic card or a pick, begin to gradually pull the Velcro towards you, this must be done smoothly and gradually increasing force. Once the glass starts to separate, use a card to peel it off. When most of the glass has separated, you can quickly tear it off.

How to glue protective glass on your phone

Gluing new glass

Before gluing the new glass, make sure that there are no fingerprints or dust left on the screen. To do this, wipe the screen with a napkin and alcohol solution.

Next steps:

Use gloved hands to grasp the edges of the protective glass.
The protective film must be removed as close to the screen as possible so that dust does not stick to the glass.
Try on the protective glass over the screen so that all the cutouts are in place.
Slowly lower the glass onto the screen, pressing and simultaneously smoothing from the center to the corners. A napkin or plastic card will help you here.

If dust or lint does get in, peel off the glass to the “dirty” area, blow out the excess or remove it with tweezers and glue the glass in place.

Such simple manipulations will help you glue the protective coating yourself.

How to stick glass on a smartphone?

Every smartphone owner understands that the screen is the weakest point in the phone. It is with the screen that problems most often occur. If the phone is dropped, the chance of the screen breaking or cracking is close to 100%. And any phone falls sooner or later, since this is the thing that a person uses constantly, one might say - from morning to evening.

To protect the screen of your favorite smartphone, smart people came up with protective glass. It is sold in any salon or store where you can buy a smartphone, and costs around 10-20 dollars.

How to properly stick protective glass on your phone

It is much cheaper to order protective glass in China.

You can stick it on with your own hands, right at home, for which you must strictly follow the instructions from the manufacturer. In general, sticking protective or bulletproof glass on yourself for the first time is not as difficult as it might seem at first. Properly applied protection to the screen will protect your phone from many troubles.

How to stick bubble-free glass on your smartphone yourself

To properly stick the second glass onto the screen, you need to follow a few simple rules:

The screen must be wiped with a special cloth, removing fingerprints, grease and other traces.
Using a stream of air, before sticking, (you can use a medical blower) blow off all the dust.
Degrease the screen with a special liquid, which manufacturers usually put in a box with tempered, armored or other protective glass. Bubbles under the glass are the result of poor cleaning.
Glue the second glass with your own hands so that there is no dirt, dust, or air bubbles under it.

To glue shockproof glass onto your smartphone yourself, you will also need scissors and tape, which will make the work easier.

We take the purchased glass and look at which side it has a sticker on. By pulling this sticker, we remove the protection. But you don’t need to remove it right away, as there is a way to make the process of even gluing easier. For this we need tape.

We cut off three small pieces of tape, apply the glass to the phone, and on one side glue the glass to the back surface of the phone. The glass will be fixed with tape on one side so that it can be opened like a door. And the tape plays the role of loops. This makes it much easier to stick the glass evenly.

We apply the protective glass and see if it lies evenly. If it fits, it should follow the shape of the screen.

If everything is smooth, pull the sticker and remove the protection. If the protection cannot be removed, then you can use a thin sheet of paper or your fingernails to pry up the protection and release the applied glass. Once again we wipe the screen and close our book from the phone and shockproof glass. Lightly press your finger into the center and admire how the second glass sticks to the screen on its own without bubbles. If air bubbles appear underneath (which should not ideally be the case), use a soft cloth to push it to the edges and get rid of them. You can glue glass perfectly only if you act carefully and slowly.

Remove the tape and clean off the glue. The gluing or glass replacement is complete.

How to re-glue a cracked plate glass to a new one

Replacing glass if it is cracked begins with removing the old protective glass. How to remove it? Very simple. You will need a sheet of paper or plastic, preferably thinner. We are trying to drive it out of the corner under the old protective glass (any kind, even 3D, even regular armored glass). As soon as you succeed, you need to try to lift the glass up. Do not press too hard, otherwise you may simply break off a corner instead of replacing it - the glass, if already cracked, will be extremely unreliable.

The old glass has been removed and the screen needs to be cleaned again before attaching the new one. Next, gluing the tempered glass will proceed as we described above. It is better to carefully glue the glass right away than to re-glue it, so be careful.

How to stick protective glass on a smartphone at home if the size doesn’t fit

If you ordered a second glass from China, there is a high probability that it will not fit. If it is a little smaller than necessary - no big deal, in principle - it will perform its function. If the glass is a little larger, it is worse, since there is a risk of it peeling off at the most inopportune moment. And it’s inconvenient to use a smartphone with a protruding screen, so in this case it’s better to replace the glass and re-stick another one. You can peel off old or broken glass yourself.

What kind of glass are there that can be glued to a smartphone?

3d - this protective glass not only protects the screen, but also makes it more attractive by rounding the corners. You can stick it yourself or in the salon.
Bulletproof glass is quite durable and protects the screen from cracks when falling even on stones and tiles. Many manufacturers produce just such glass. It is better to buy and stick such glass right away, especially if you often drop your phone.
Tempered glass (or tempered glass) is highly durable and protects the screen from breaking.
Shockproof is suitable for those who often drop their phone or have a habit of throwing it on the table. It is as easy to stick as other types.
Liquid - applied as a spray, provides oleophobic, hydrophobic and antibacterial coating. Saves from small cracks. Can be reapplied.

The first four types relate to invoices and have many similarities. Before you buy an overlay glass, you need to know the exact dimensions of your smartphone screen. Liquid protection is suitable for any device. Even if you handle your phone carefully, it is better to stick glass with an additional oleophobic coating.

What to do if the glass glued to your smartphone comes off?

If additional glass recently glued to a smartphone comes off, it means it was most likely defective. This happens if you bought it from a Chinese manufacturer. There is nothing you can do here, so all you have to do is get rid of the low-quality product and buy new glass.

If the reason is not the additional glass, then you can try to clean the screen again - after all, the second protection will be perfect only if the grease, dust and dirt are completely removed from the smartphone.

Important: The Glass (Gorilla) screen, which is considered extremely durable, also needs additional protection. Therefore, even for such smartphones it is important to choose glass. In addition, you can choose a rear glass to protect the body.

Every smartphone needs protection. Even if you purchased an iPhone, do not refuse to put on a protective glass. After all, replacing a protective glass is several times cheaper than replacing a screen. With a protective glass on your smartphone, you won't be afraid of scratches and other damage if you know how to properly stick the protective glass on your smartphone at home. The task is not an easy one, but if you follow these instructions, you can easily glue the glass at home, without asking third parties for the service.

If you are encountering this for the first time, it may seem to you that this is a very difficult process. But once you practice, you will be able to glue glass without difficulty and without bubbles.

Let's move away from the topic a little. I will say on my own behalf, I personally do not buy glass in the city. I buy glass on Aliexpress. Previously, of course, I bought glass in stores in the city and also paid to have it glued on. And now I buy glass for myself and friends on Ali, since I haven’t noticed a difference in quality, and the cost is 3-5 times higher. So I advise you to take several glasses from different sellers for your smartphone and try to stick them on. After all, you must admit that if you spoil glass bought in the city for 700 rubles, it will be very sad. And on Aliexpress you can buy 4-5 glasses in one day. and enter your smartphone model and select.

And so, let's return to the process of gluing glass. It makes no difference whether you glue the glass onto an iPhone, tablet or some other device, the process is the same everywhere.

The display of a smartphone is very sensitive to mechanical damage, no matter how much it was purchased for. A phone in your pocket can get scratched by anything, coins, keys, or even nails. And if there are already scratches on the screen, then when gluing there will be bubbles that are almost impossible to remove.

What you need for gluing glass:

Alcohol wipe
Dry cloth
special liquid for cleaning TV or computer screens
tape or dust bag
glass

Usually everything you need for gluing comes with the glass.

The most important thing is the room in which the gluing will be done. This should be a room with minimal dust. A kitchen or bathroom is best. The bathroom has the highest humidity and therefore a minimum of particles in the air, which is exactly what we need. Run a hot shower for a few minutes to raise the humidity and you’re good to go. Yes, gluing will not be entirely comfortable, it will be stuffy, but it’s worth it, the glass will be glued perfectly, without lint or bubbles.

Wash your hands with soap, then place the equipment, protective glass for iPhone 6 or other phone on a clean, smooth surface.

Before starting the procedure, remove the old film from the device. To do this, slightly pull the edge at a 60 degree angle.

Use a cloth with alcohol to wipe off dirt from your phone screen to ensure a perfectly clean surface.

If there are dust particles left, we go over the surface with tape or a dust collector.

We take the glass out of the packaging and remove the film from it. We install the protection so that it matches the central button of the gadget and the speakers. Slide your finger down the center from top to bottom to secure the overlay. If the air remains, we expel it with a credit card or the device that comes with the kit.

There is no need to try with all your might to squeeze out the remaining small bubbles. if you overdo it, you can crush the screen) After a couple of days, they will disappear on their own if you did everything correctly and if it is not the villi that are creating the bubbles.

Having picked up a brand new, cutting-edge smartphone for the first time, the new owner of a convenient, functional communication device understands: the display is the most vulnerable area. But it is he who is the main center of communication between the device and the user. How to protect the display from mechanical damage? If we are talking about a smartphone, for example Xperia, experts do not recommend gluing the film for the reason that special protective glass can be purchased for the vast majority of models of modern smartphones. Currently, many variations of this accessory are presented in abundance on the most advanced trading platforms.

As practice shows, no matter how reliable the standard smartphone display glass is, extra protection will not hurt it. Accidental impacts and falls, active use, carrying the device in a pocket or bag - all this will invariably lead to scuffs and cracks appearing on the glass.

Protective glass, the thickness of which varies from 0.2 to 0.3 mm, consists of five layers:
Oleophobic layer. Allows your finger to glide across the screen freely and smoothly. The layer effectively repels moisture. Fingerprints can be easily removed with an ordinary cloth.
Protective layer (hardness 9H). Gives glass resistance to mechanical stress (impacts, scratches).
Anti-blocking layer - prevents the screen from fading.
The so-called containment layer. Even if you somehow manage to break the screen, this layer will prevent it from falling into pieces.
Silicone base. Reliably fixes the protective glass on the screen.

The process of sticking such a protective glass on the smartphone screen is very simple, you just need to follow the recommendations specified in the instructions. Usually, the protective glass kit includes everything necessary to fix it on the smartphone screen:
cloth for pre-cleaning glass;
wet and dry wipes for degreasing and wiping;
adhesive strip designed to remove settled dust;
a couple of small adhesive strips to properly fix the glass on the device display.

The protective glass is glued to the smartphone very quickly. To do this, you just need to use all the materials at hand for their intended purpose, following the instructions exactly. If during the process of attaching the protective glass an air bubble has formed under it, you just need to gently push it with your finger, move it to the edge and remove it.

Instructions: how to install protective glass on your phone

We have prepared a short instruction manual for those who want to install the glass themselves.

The article contains basic information, but to complete the picture, we recommend watching a video with a detailed description of the installation stages.

Removing old glass: what is important to remember

You must understand that the glass does not stick to the screen due to a special adhesive coating. The adhesion of the film to the smooth surface of the touchscreen occurs due to statics. An attempt to remove it by prying it with a fingernail or (much worse) with a knife will end in damage to the screen and body of the phone.

Even using a special suction cup can lead to unpleasant consequences. Remember, perform all actions smoothly. By pressing hard on the Velcro, you risk damaging the cables or tearing off the screen module. A vacuum is formed between the glass and the film, which will resist the adhesion of the coatings. But even if the suction cup adheres well to the film, there is a chance of damage to the sensor when removing the protective glass. Therefore, act consistently and carefully.

What to prepare for installing protective glass:

mediator (or thin plastic card) - it’s better to take 2 pieces;

silicone suction cup (if you already have reinstallation experience, you can do without Velcro);

napkin or piece of lint-free cloth;

glass cleaner containing alcohol (pure alcohol or perfume will also work);

medical gloves (silicone or rubber).

Once armed with these tools, the job will take no more than two minutes.

Brief description of the process

Before you begin, make sure your hands are free of dust or lint. It is impossible to see the smallest particles on your fingers, so it is better to play it safe and wear medical gloves. They are thin and fit snugly on the hand, so they will not interfere with work.

Next, install the suction cup on the area of the phone with damaged glass, where there are fewer fragments and cracks. Carefully apply the Velcro to the corner of the screen, and then press down slightly and glue it to the glass. Take the pick and pull the suction cup towards you, only gradually increase the force, otherwise the glass will come off along with the screen.

As soon as you feel the glass peeling off, deepen the pick.

When the glass around the perimeter peels off ~80%, feel free to pull the suction cup and tear off the old screen.

Gluing new glass

Before applying new coating, remove dust and fingerprints. A lint-free cloth is suitable for this: first moisten the screen with glass cleaning compound and degrease the surface using a prepared cloth.

Grasp the protective glass by the edges (put on gloves first).

Carefully remove the adhesive protective surface on the film (keep the glass near the phone, otherwise airborne dust will stick while you transfer the film).

Place the glass as close to the screen as possible (align it relative to the center, check that all holes for buttons, connectors and the camera pass through the film).

Slowly lower the protective covering onto the screen, pressing and simultaneously smoothing from the center to the corners. Use a dry, lint-free cloth or thin plastic card for this.

Remove the film applied for protection during transportation.

It is not always possible to glue glass to a phone without getting dust and lint. If you see that debris has gotten under the film, peel off the glass exactly to the place where there is dirt.

You can also use a compressor, a technical vacuum cleaner, or a can of compressed air to blow out dust particles.

If you don't have anything like this at hand, use tweezers.

As soon as you remove the dirt, glue the glass back.
