It contains a speaker, a headphone jack, and two antennas: one from the wireless Wi-Fi module, the other from the GPS satellite navigation system. This smartphone unit can be easily replaced if defects occur. You can find a new part on eBay or Amazon 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 any 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 spatula, separate the block from the case on the left side and remove it. Install the new part by snapping the latches and plug in the plug.

Complex 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 system board, soldering of 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 need to replace the protective glass. This problem is eliminated quickly: you need to get rid of the remnants of the old protection, clean the surface well, and stick a new tempered glass. The cost of glass is included in the total cost of all work.

A frequent breakdown in such models of phones is a 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 item. All necessary actions: remove the touch panel, disassemble the phone, disconnect all the necessary cables. Next, you should get rid of the non-working element and mount the working screen.

Broken sensor - does not allow you to use all the functions fully. To replace a broken touchscreen (sensor) on a Samsung Galaxy S3 series smartphone, you need to heat up 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 the repair is taken from the price of the purchased module.

What should I do if the Samsung Galaxy S3 does not work, does not turn on, and does not charge when connected to a charger? 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 power supply, battery, or charge controller. After the 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 protective elements and tires of the device, and use a soldering station to solder a new charging socket. The procedure is not complicated, so it does not require a lot of money.

Samsung Galaxy S3 won't boot screensaver hangs, lags, slows down, freezes when turned on, red blue indicator is on

The problem of many Samsung Galaxy S3 is that over time the phone does not boot up or the splash screen hangs during loading, during operation it lags and slows down endlessly, and also freezes when turned on and at the same time the red or blue indicator is constantly on. All these "symptoms" may 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 the replacement of the damaged case of the Samsung Galaxy S3 smartphone is an obvious necessity. During replacement, you need to completely peel off the sensor, dismantle the screen and the board. Further, all elements are installed in a new purchased case.

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

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

If, during a conversation on the Samsung Galaxy S3, the interlocutor does not hear a voice due to the fact that there is no sound, then the conversational microphone is not working, and the non-working part needs to be replaced. 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 replaced urgently, since without it the battery cannot be charged. For replacement, you need to disassemble the rear protective cover and dismantle the tire. A broken socket is removed on the board and a working part is soldered using a soldering dryer. At the end is the assembly of the phone.

If the Samsung Galaxy S3 suddenly stopped both receiving and sending text messages (SMS), but did not stop receiving or making calls, then the problem is in the operating system. By installing a 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 simple. 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 conversation, on the Samsung Galaxy S3, you can’t hear your interlocutor constantly, replacing the earpiece speaker will solve the problem. Such actions will require a complete disassembly of the gadget. And here are two options: a complete replacement, or repair of the conversational speaker. 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 cable inside a Samsung Galaxy S3 line is a delicate job that should only be done by an experienced technician. This is not about Chinese cables that can be mounted with a screwdriver, thin soldering is needed here 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, a complete replacement of the entire module is a last resort, but an effective one. The entire rear part is completely removed: battery, board, WiFi antenna, camera and board. All parts, except for the sensor and screen, are placed in a new module. The solution is expensive, but at the end of the installation, the smart will be with a new screen, touch, control buttons and a case. Thus, the fix is worth the money.

The next issue that can occur with the Samsung Galaxy S3 is that it won't connect to a WiFi network. 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 a damaged WiFi module. Replacing it will cost more, but in the end, the phone will fully function.

Damaged control buttons are normal after long-term use. A 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 the workshop, the cost will include material and labor intensity.

Over time, the following trouble occurs in the Samsung Galaxy S3: the built-in camera does not work (does not focus). This failure can have two types, one is software, and the other is a system malfunction. The first error is easily fixed by resetting all settings, or flashing. The second failure is eliminated by the complete replacement of the phone camera module.

If the battery and charger are fully functional, but the Samsung Galaxy S3 is not charging, you need to replace the internal battery power controller. To do this, the device is completely disassembled, and the element that has failed is replaced with a serviceable one. The master must perform all actions carefully and carefully so as not to damage neighboring elements. Repair 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 batteries (battery) on the SamsungGalaxy S3. Service services are needed only to determine the malfunction. You will only be charged for a new battery. Therefore, repairs will be inexpensive.
