Despite the progressiveness of modern technologies, the operational reliability of communication devices produced today still leaves much to be desired. If your phone “uncomfortably” fell or you accidentally crushed it in your pocket (the object of our story will be the Samsung Galaxy S3), glass replacement will be required immediately. As a result, this kind of repair will cost the owner of the "injured" smartphone a decent amount (meaning the specifically mentioned model). After all, the services of specialists are not a cheap pleasure, especially when it comes to repairing far from budget devices. However, there is a less expensive way to restore the protective screen - to change the cracked body element yourself. Well, you will learn about all the subtleties and nuances of such a responsible event from the material presented below.

A little about the design features of the Samsung Galaxy S3 that are of interest to us

Replacing the glass on this model is a very time-consuming process, since the transparent protection element is firmly glued to the display module. To "painlessly" separate the front panel, you need to try hard. In service workshops, specialized equipment, the so-called separators, is used for such operations. At home, it is much more difficult to implement the separation process. Nevertheless, we hasten to please you. Subject to certain dismantling rules and relying on the invaluable experience of the decisive and courageous, the Samsung Galaxy S3. Replacement of glass "is quite feasible even by the hands of a person whose knowledge in technical aspects is equal to absolute zero. However, we will not be silent, in the process of the cosmetic repair agreed upon by us, the performer must be very attentive and extremely careful. Let's not forget the main thing - a smartphone costs money!

Preparatory stage: workplace

You will get acquainted with the list of improvised means a little later. Now let's specify what needs to be considered when organizing the workflow:

• Lighting should be sufficient, but not irritating to the eyes.
• There should be nothing superfluous on the desktop.
• Nobody should distract you.
• Pleasant, and at the same time your favorite music, let it become your second assistant.

Regarding the Samsung Galaxy S3 Disassembly Tool and Aids

Do-it-yourself glass replacement is a very responsible process. This will be said more than once, since this type of repair is really difficult to perform. Therefore, before proceeding with the direct implementation of restoring the aesthetic originality of the device, think again whether you can carry out your plan. Decisive and courageous will be able to significantly save on the services of professionals.

So, what do you need from the tools in order to remove and install a new one?

• Phillips screwdriver (very thin profile).
• Hairdryer with temperature controller (industrial or domestic).
• Old bank card.
• Several plastic picks.
• Special spatula for prying sealed glass edges.
• A scalpel or a small pointed knife (certainly sharp).

By the way, as an encouragement: the owner of S3 glass replacement in Zelenograd will cost about 2000 rubles. However, prices for this type of repair in other cities of the country may vary slightly. In any case, if you purchase a new one in a specialized store and install it yourself, the benefit will be obvious (the price of the part varies depending on the quality of the product within 100-1000 rubles).

Let's start simple: preparing to remove the glass

• Remove the rear protective cover.
• Disconnect the battery of the device.
• Remove the SIM and memory card.

There is no need to unscrew the screws and remove attachments. The more rigid the structure, the better.

Warming up the screen plane: an extremely crucial moment

Repair of the S3 device - replacing the glass separately from the module - implies the mandatory use of a hair dryer, since the protective element is firmly glued to the touchscreen of the device. However, touch navigation buttons located at the bottom of the phone are also firmly fixed with the above-mentioned fixing substance. As you understand, the glue must be softened before separating the glass from the module.

• Turn on the hair dryer and adjust the temperature of the forced air to the optimal mode (50-70 degrees Celsius).
• In a circular motion, holding the nozzle at a distance of 3-5 cm from the glass, warm the surface to a state of tangible heat.
• Using a spatula or knife, carefully pry off any of the top edges of the protective element.
• Insert one of the prepared mediators into the opened lumen.
• Make at least three points of "undermining" the glass (at the top).
• Repeat the warm-up process briefly.

This is just the beginning of working with the Samsung Galaxy S3. Replacing glass further will require more painstaking efforts. Be careful and you will succeed!

Separating the glass from the display module

• When the protective element slightly moves away from the case and the screen, insert a bank card into the freed gap.
• Slowly and very carefully move the parting tool inside the part towards the center until the edge of the credit card pops out on the other side of the display module.
• Systematically warm up the adhesive.
• Gradually, and most importantly, slowly move the bank card down the plane to the main navigation buttons.

Attention: touch sensors (keys mentioned above) must be carefully separated from the glass until the part to be dismantled is completely removed. Otherwise, there is a high probability of damaging the connecting loop of the buttons, which means that a visit to the service center simply cannot be avoided. However, you can always fix your Samsung Galaxy S3 (glass replacement), whether in Tyumen, the city of residence, or another. However, in our case this is not an option.

Cleaning the display module

After you manage to painlessly remove the glass, you need to remove the remaining adhesive from the surface of the touchscreen.

• The adhesive can be easily removed with a regular window cleaner. However, before using such a tool, you need to make sure that its composition does not have aggressive active substances.
• Ordinary microfiber will help you bring the final gloss to you.

Installing a new protective part

Glue the inner edges of the smartphone (around the perimeter of the screen) Make sure that the fixing tape does not extend beyond the frame frame and does not overlap the outer areas of the display module. Position the part to be installed. Remember that in the event of an incorrect position of the glass, it is one hundred percent likely that dust and moisture will penetrate the screen. Agree, after such painstaking work to expose the phone to another risk of failure is, to put it mildly, a somewhat frivolous act.

It is worth noting when performing S3 repairs (glass replacement): St. Petersburg is a city in which specialized workshops use practically factory technologies. That is, a new protective element is mounted using a special adhesive, followed by ultraviolet treatment. Of course, such a recovery scenario is also possible at home, but only on condition that the performer has the appropriate equipment and, of course, is not deprived of proper experience.

You can't do without rules...

You will be surprised, but a broken display or mechanical damage in the form of deep scratches is the result of adverse situations that are generally quite predictable, which means that all this (and much more) can be easily avoided if:

• Transport your smartphone in a special case equipped with stiffeners.
• Do not carry your device in the back pocket of tight pants.
• In crowded places (metro, minibus) keep the phone in hand.

However, the human factor cannot be ruled out, and, as you understand, it will not be possible to foresee everything, and therefore be careful in any situation.

Whether an independent repair is advisable is up to you, and it depends only on you how justified this kind of undertaking is. And yet the game is worth the candle! In the event that your Samsung Galaxy S3 smartphone needs a camera glass replacement, the solution is even simpler: unscrew the ten fixing bolts and remove the body frame.

On the reverse side of the removed part, it is required to unsolder the plastic holders, and only then subject the damaged protection element to the direct replacement process. With this knowledge, you have only one thing left - to use everything in practice. However, be wise and save wisely!

Is the glass on your smartphone damaged? Don't worry, we'll fix it. First, make sure the display is OK. If yes, then replacing the glass on the Samsung Galaxy s4 will help in solving the problem.

It is with such a problem that owners of gadgets most often turn to service centers. Such breakdowns are not uncommon. A strong impact, falling or squeezing the device is not good for the glass. As a result, cracks appear.

Features of glass replacement on Samsung Galaxy

Regardless of the damage, chips, small cracks on the screen, graphic artifacts or smudges, the glass needs to be replaced.

1. If the display is damaged under the glass, you will notice this by the stripes that appear, and the color rendition will change. In this case, a repair is also provided, the manufacturer has provided for the replacement of the display module, consisting of a screen, sensor and glass.
2. Don't go to private companies. Not the fact that they will replace the original glass on the smartphone. Fakes are thicker, they lack tinting and a special protective coating. And that means it will need to be redone soon. The glue used to replace glass in dubious service centers is mostly of poor quality. As a result, stains and stains appear on the glass. There are also such "craftsmen" who simply fasten the part with adhesive tape.
3. In reliable service centers, glass replacement for Samsung Galaxy is carried out using modern technologies on special equipment. This saves all processes used by the manufacturer, since the replacement is carried out separately from the module.

Benefits of repair in a service center

The repair is carried out in compliance with all the rules - removal of damaged glass, thorough cleaning of the inside of the gadget, installation of a new original part with a protective coating applied.

1. Repair work is carried out by professionals who have the necessary skills and experience in using special equipment.
2. Replacing glass is not the most difficult task, but it is not easy to do at home without the special equipment and tools available in workshops.
3. Guarantee for all types of services.
4. High quality optical adhesive is used.
5. There is a glass for a smartphone of any color.
6. A fixed price for Samsung Galaxy s4 glass replacement, which is much lower than the cost that private masters will announce to you.
7. The quality corresponds to the factory parameters, which means that the glass will serve you for a long time.

How to make a replacement at home

It is worth noting that this method requires special skills, and not everyone can do it. So it's not worth the risk. In addition, you will need a special device for replacing protective glasses. However, if you are sure that you can handle it, you can try. And this guide will help you.

• open the cover by unscrewing the nine bolts;
• carefully snap off the coaxial cable, loops;
• unscrew the bolts holding the reconciliation board:
• remove the boards, leaving the display module in place;
• take the device, set the temperature to 80 degrees;
• place the module on the separator, warm it up for several minutes:
• you will see a gap into which you need to insert a strong thread, and slowly begin to separate the glass;
• clean the display thoroughly from the old glue;
• connect the module to the board;
• insert the module;
• in the engineering menu, dial the combination * # 0 * #, from the proposed one, select "touchscreen test":
• if everything works, apply special glue;
• dry the device in the apparatus;
• assemble by screwing all the bolts.

Summing up, we note that a repaired smartphone in a service center is no different from a device just purchased in a store. And replacing glass on a Samsung Galaxy s4 by a professional does not take more than 1.5 hours. We recommend that you do this only at a service center, so as not to pay even higher amounts for repairs later.

Firstborn payments

The state is ready to financially support low-income families who are postponing the birth of their first child - they will be able to receive benefits in the amount of the subsistence level in their region, President Vladimir Putin announced on Tuesday. “I think it’s fair to first of all support those who really need it,” the president said. According to him, payments will begin on January 1, 2018 and will continue until the child reaches the age of one and a half years. The average payment in 2018 will be 10,500 rubles.

Maternal capital

The maternity capital program will be extended until the end of 2021, and the possibilities for using this capital will be expanded: money can be spent on caring for and looking after children. Families in particular need will be able to receive maternity capital in the form of monthly payments.

Obligation to give birth

Families participating in a special mortgage program will have to commit themselves to having a second and third child by a certain date, according to Putin's statement. The program provides for "subsidizing an interest rate by the state in excess of 6% at the birth of a second child and for three years from the date of issuance of the loan." At the birth of a third child, the period of subsidizing the interest rate will be five years from the date of issuance of the loan.

"According to the Ministry of Construction, in the next five years, this program can cover over 500,000 families," Putin said.

From kindergarten to nursery

The state will pay for the birth of the first child

Vladimir Putin, at a meeting of the Presidential Coordinating Council for the Implementation of the National Strategy for Action in the Interests of Children for 2012-2017, proposed introducing monthly payments to young families from 2018 upon the birth of their first child until they reach one and a half years.

According to him, the amount of payments will be calculated from the subsistence level of the child, established at the regional level for the second quarter of the year preceding the year of applying for such a payment.

On average, the benefit will be 10,523 rubles in 2018, 10,836 rubles in 2019, and 11,143 rubles in 2020.

The head of state also announced the launch of a program to subsidize the mortgage interest rate for families with a second and third child, starting in 2018.

As Vladimir Putin noted, the weighted average mortgage rate, according to the Central Bank, is 10.5%. If a family with a second or third child takes out a mortgage at this rate, then the state will help with paying a share of 4.5%, and the family will be left with 6%.

Putin also proposed extending the maternity capital program until December 31, 2021, as well as expanding its scope. He added that maternity capital can now also be used to pay for preschool education services - to care for and look after a child from the age of two months.

Russian President Vladimir Putin proposed from January 2018 to introduce monthly payments for low-income families at the birth of their first child. In addition, the maternity capital program is being extended, and for families in which a second or third child is born in 2018, the state subsidizes the mortgage rate.

Firstborn payments

This is one of a package of measures aimed at increasing the birth rate: the demographic situation in Russia is again predictably aggravated due to the overlap of two demographic recessions - the post-war and early 1990s, Putin recalled. A new set of measures is needed to stabilize the situation.

Payments for the birth of the first children will cost 114.5 billion rubles. over the next three years, Putin said.

Maternal capital

Co-financing from the federal budget for the payment of benefits for the third child will continue to be received by regions with an unfavorable demographic situation. Since January 1, 2018, there have been 60 such regions (10 more than this year). We are talking about subjects in which women give birth on average to less than two children.

Obligation to give birth

For families planning the birth of the second and third children, a special mortgage program will be launched - the state will pay more than 6% of the mortgage rate, the president said.

From kindergarten to nursery

The authorities have almost managed to solve the problem with the availability of kindergartens, now they need to solve the problem with the availability of places in the nursery, the president recalled. It is also necessary to move to the reconstruction of children's hospitals and polyclinics after "a good breakthrough with the advent of perinatal centers," Putin said. He estimated the cost of this reconstruction for the budget at 50 billion rubles, the regions do not have that kind of money, so the federal budget will take on most of the costs in the next three years, Putin said.

"I am sure that the implementation of all these measures will bring results," the President concluded the presentation of the package.

Today Putin took part in the final meeting of the presidential coordinating council for the implementation of the National Action Strategy for Children for 2012-2017. The Coordinating Council was established in September 2012 and prepares proposals to the President on the priorities of state policy in the interests of children.
