Samsung's Galaxy S III i9300 is fairly easy to repair. For example, you can replace the Wi-Fi antenna or SIM card slot yourself.

Place the Galaxy S III screen-side down on a soft cloth to avoid scratching the display. Remove the back cover, remove the battery, SIM card, SD memory card and set them aside. Then, using a Phillips screwdriver, remove the ten screws holding the rear plastic panel of the case. Grasp the side of the bezel between the battery compartment and the outside and gently pull it away from the body until the latch at the top near the camera releases. After that, the panel can be easily removed. Set it aside so as not to accidentally touch it during further manipulations.

Now, at the top of the phone, you will see a plastic piece that spans the entire width of the motherboard. It contains a speaker, a headphone jack, and two antennas: one from a wireless Wi-Fi communication module, the other from a GPS satellite navigation system. This smartphone unit can be easily replaced if defects occur. You can find a new part on eBay or Amazon online by searching for “i9300 buzzer”. Regardless of the color, it will cost you less than 400 rubles / 100 UAH. (excluding shipping costs). Replacement will not cause problems: use your fingernail or a small spatula to disconnect the plug under the camera that connects the module to the system board. Then, using a spudger, pry the block off the left side of the housing and pull it out. Install the new part by snapping the latches and plug in the plug.

You will find a new part on the same network sites by entering “i9300 card holder slot” in the search, it will cost less than 300 rubles / 75 UAH. (excluding shipping costs). Disconnect the connector plug, then carefully slide a spatula under the slot that is adhered to the adhesive near it and disconnect it. Install a new part.

If you need to replace the main camera or display, you will have to remove the system board. To do this, disconnect the connector that leads from the battery compartment up to the system board, then the oblong connector for the front camera located opposite, and finally the display connector located at the bottom left. Unscrew the only black screw and also disconnect the antenna plug at the bottom right. Pull out the antenna by prying it slightly at the top mount. Then, gently pull out the motherboard along with the main camera.

The display, the plastic frame of the front panel of the case and the touchscreen of the Galaxy S III in the form of a single module (enter “i9300 led” in the search) are available at a price of 4500 rubles (1100 hryvnia). Transfer all other parts from the old bezel to the new one. These include a vibration signal (bottom right), a front camera and a proximity sensor (top, one screw), a bundle of wires with a phone speaker, an LED, a volume control (push the control outward, carefully lift a bundle of wires) and a power button (push out).

Complicated repair, as well as simple repair and maintenance of Samsung Galaxy S3. Replacement and repair of the display, repair and replacement of connectors, replacement and repair of the motherboard, soldering tracks and contacts, cleaning after liquid has entered. Samsung service offers modern European equipment, original spare parts.

The protective glass is quite fragile, and even with careful use it can be seriously damaged. Therefore, the Samsung Galaxy S3 may require replacement of the protective glass. Such a problem is quickly eliminated: you need to get rid of the remnants of the old protection, clean the surface well, and stick on new tempered glass. The cost of glass is included in the total amount of all work.

A frequent breakdown in such phone models is screen breakage. The only solution to this problem is to replace the non-working screen (display) of the Samsung Galaxy S3 phone with a working element. All necessary actions: remove the touch panel, disassemble the phone, disconnect all necessary cables. Next, you should get rid of the non-working element and mount the working screen.

Broken sensor - does not allow full use of all functions. To replace a broken touchscreen (sensor) on a Samsung Galaxy S3 smartphone, you need to warm up the double-sided tape and replace the damaged touchscreen with a new one. Before gluing the sensor, it must be connected to the board. The cost of repairs is taken from the price of the purchased module.

What to do if Samsung Galaxy S3 won't work, won't turn on and won't charge when plugged in? There can be many reasons, and in order to understand them, you need to take the device for repair. The device may not turn on due to a broken AC adapter, battery, or charge controller. After diagnostics in the service, the cost of the repair will be known.

If the Samsung Galaxy S3 refuses to charge, then replacing the old connector (socket) for charging (power) will help. Since the socket cannot be repaired, it is simply removed from the circuit board. To do this, remove all the protective elements and busbars of the device, and using a soldering station, a new charging socket is soldered. The procedure is not complicated, therefore it does not require a lot of money.

Samsung Galaxy S3 does not load; splash screen hangs, lags, slows down, freezes when turned on, red blue indicator is on

The problem with many Samsung Galaxy S3s is that over time, the phone does not boot or the splash screen hangs when loading, during operation it lags and endlessly slows down, and also freezes when turned on and the red or blue indicator is constantly on. All these "symptoms" can occur due to incorrect operation of the system. They are eliminated by installing a new firmware.

A broken case does not affect the performance or operation of the gadget in any way. But it seriously spoils the appearance, and therefore replacing the damaged Samsung GalaxyS3 smartphone case is an obvious necessity. During replacement, you need to completely peel off the sensor, dismantle the screen and board. Further, all elements are installed in a new purchased case.

Time passes and Samsung Galaxy S3 gives a problem: it not sees inserted Sim map (sim card), and, therefore, No the network, and the connection with the internet... A breakdown may lie in a non-working card slot or in the tracks themselves on a SIM card.If everything is in order with the other SIM card, then there is a breakdown inside. The master repairs a non-working module, or solders a new element. The price depends on the work done.

Often they turn to the service center with such a breakdown: the Samsung Galaxy S3 began to reboot itself for various reasons, while it turns on and off itself, which is why it often glitches. The reason can be determined without disassembling the device: it closes the power button. The disease is treated by replacing the inoperative button with a serviceable part. The work is not difficult, it is done quickly.

If during a conversation on Samsung Galaxy S3 the interlocutor does not hear a voice due to the fact that there is no sound, it means that the conversational microphone does not work, and the replacement of a non-working part is necessary. In order to get close to it, the master needs to completely disassemble the back panel and unsolder the broken part. He replaces it with a new microphone, and then reassembles the device.

If the charging socket or usb connector installed on the Samsung Galaxy S3 phone is out of order, it needs to be urgently replaced, since without it it is impossible to charge the battery. For replacement, you need to disassemble the rear protective cover and dismantle the tire. The broken socket is removed on the board and the work piece is soldered with a soldering hair dryer. At the end, the phone is being assembled.

If the Samsung Galaxy S3 suddenly stops receiving and sending text messages (SMS), but does not stop receiving or making calls, then the problem is in the operating system. Having installed the new firmware using a special utility, you can resume the ability to send messages. The procedure is simple and relatively inexpensive.

Having connected the Samsung Galaxy S3 via a cable, the computer does not want to see the device (the computer does not see the phone connected via the usb cable), the solution is to replace the usb connector. The procedure is inexpensive because it is not complicated. You just need to dismantle the unnecessary part and put a working USB. After repair, the connector will serve for a long time and will not fail soon.

If during a call, on the Samsung Galaxy S3, it is constantly difficult to hear your interlocutor, the problem will be solved by replacing the earpiece. Such actions will require a complete disassembly of the gadget. And here there are two options: complete replacement, or repair of the earpiece. Due to the low cost of this part, it is most reasonable to make a modular replacement. As a result, we get a loud speaker.

Replacing a damaged ribbon cable inside a Samsung Galaxy S3 line is a delicate job that should only be done by an experienced craftsman. We are not talking about Chinese cables, which can be mounted with a screwdriver, here you need a thin soldering using special equipment. The cost largely depends on the price of the loop, as well as the complexity of the work.

On the Samsung Galaxy S3, completely replacing the entire module is a last resort, but effective. The entire back is completely removable: battery, board, WiFi antenna, camera and board. All parts, except for the sensor and the screen, are placed in the new module. The solution is expensive, but at the end of the installation, the smart will have a new screen, tach, control buttons and a case. Thus, the repair is worth the money.

The next problem that can arise with the Samsung Galaxy S3 is that it won't connect to WiFi. There may be several reasons. The first is that the antenna inside the case is damaged, and all that needs to be done is to replace it. And the second problem is the damaged WiFi module. Replacing it will cost more, but in the end, the phone will be fully functional.

Broken control buttons are normal during long-term use. Complete replacement of the mechanical power button (volume, home) on the Samsung Galaxy S3 case is carried out in almost any repair service. The work is painstaking, but, despite the complexity of the repair, it will be cheap. In a workshop, the cost will include material and labor input.

Over time, the Samsung Galaxy S3 has the following problem: the built-in camera does not work (does not focus).This breakdown can be of two nature, one is software, and the other is a system malfunction. The first error is easily eliminated by resetting all settings, or flashing. The second breakdown is eliminated by completely replacing the phone camera module.

If the battery and charger are fully functional but the Samsung Galaxy S3 is not charging, the internal battery controller needs to be replaced. To do this, the device is completely disassembled, and the failed element is replaced with a serviceable one. The master must perform all actions carefully and carefully so as not to damage the adjacent elements. The renovation will be expensive, but in the end it will fully meet expectations.

If the battery is swollen or stops working, the phone cannot be used. The only solution would be replacement non-working battery (battery) on the SamsungGalaxy S3... Service services are needed only to determine the malfunction. Only a new battery will be charged. Therefore, repairs are inexpensive.
