The most popular Samsung models and their breakdowns:

Repair Samsung Galaxy S/ Galaxy S+ (Samsung i9000/i9001/i9003)

The most common failures of Samsung i9000 (Galaxy S) and Samsung i9001/i9003 (Galaxy Es+):

The display is broken
Touchscreen doesn't work
Display glass is broken
Phone won't charge
Samsung i9000 won't turn on
Inaudible during conversation (microphone)
No call sound
The phone does not recognize the SIM card

Samsung Galaxy S - the first phone in the line model range Samsung Galaxy, despite the fact that it was a pilot model, is quite reliable mobile phone, most of the malfunctions of which are caused by careless and careless handling.

The most common breakdowns of i9000/i9001

Naturally, due to the large area, if handled carelessly (falls, impacts), the display module is the first to fail - the protective glass breaks, and the sensor also fails.

In second place are malfunctions caused by liquid ingress - lack of charge, connection to the computer (the charger connector needs to be replaced), unexpected “glitches” and other equally unpleasant things.

In third place are software glitches - Android - stable operating system, but because large quantity third-party software, it also has glitches.

Samsung Galaxy S2 (Samsung i9100) repair

The Samsung Galaxy S2 appears for repairs, a little less often than the i9000/i9001, but that too breaks down. List of major breakdowns:

The display module is broken
No charging
The phone is always charging
Touch keyboard doesn't work
Galaxy S2 does not connect to the network
Errors when connecting to a computer
Samsung does not see the flash card

The world does not stand still and after the phenomenal success of the Samsung Galaxy S, came the even more successful Samsung Galaxy S2. As you can see from the list above, it inherited the weaknesses of its predecessor - instability to falls and shocks, as well as weakness to moisture and being in an environment with high humidity, failures of which manifest themselves mainly in failure to charge the phone .

This problem is caused by the fact that Samsung uses micro USB connectors, with an increased number of contacts - instead of the usual 5, they contain from 7 to 9 contact pads. As a result of this miniaturization, when liquid gets into the connector area, a short circuit occurs and subsequent “glitches” occur.

This breakdown can be avoided by protecting your phone from water, but if this has already happened, don’t hesitate to call us - we will definitely be able to help you with repairing your Samsung.

Samsung Galaxy S3 (Samsung i9300) repair

Samsung I9300, better known as Samsung Galaxy S3, is not often brought in for repairs, but we are already closely familiar with it:

Glass breaks
The phone is always charging
The center button doesn't work
Touch keys don't work
Poor signal reception level cellular network
Galaxy S3 freezes
I9300 is not seen by the computer

Surely, having looked at the lists of main faults, you noticed that in all three cases, there are certain malfunctions of the display module - broken glass, a non-working sensor, a non-working or poorly functioning display. All this, moreover, is aggravated by the fact that the replacement of each of these components involves the replacement of two other (and when using original spare parts, several dozen other) components.

But you shouldn’t blame the creators of the Samsung i9000/i9100/i9300 for low-quality spare parts, because all these malfunctions are caused exclusively by careless handling of the cell phone, in this case by impact or ingress of liquids.

Remember, the performance of your phone depends only on how carefully you handle it, and if a problem has already happened, don’t worry! Just call us!
