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 (Gelexi Es +):

Broken display
The touchscreen does not work
Broken display glass
The phone won't charge
Samsung i9000 won't turn on
Can't hear during conversation (microphone)
No call sound
The phone does not see the SIM card

Samsung Gelexi S - the first phone in the line lineup Samsung Galaxy, despite being a pilot model, is quite reliable mobile phone, most of the malfunctions of which are caused by careless and careless handling.

Most frequent breakdowns of i9000 / i9001

Naturally, due to large area, in case of careless handling (falls, blows), the first, the display module fails - beats safety glass, as well as the sensor fails.

In second place are malfunctions caused by liquid ingress - lack of charge, connection with a computer (it is necessary to replace the charger connector), unexpected "glitches" and other, no less unpleasant things.

In third place - software glitches - Android - stable operating system but because of a large number third-party software, it also crashes.

Repair Samsung Galaxy S2 (Samsung i9100)

Samsung Galaxy S2, appears under repair, a little less often i9000 / i9001, but it breaks down too. List of major breakdowns:

Broken display module
No charging
The phone is "always charging"
The touch keyboard does not work
Galaxy S2 does not catch the network
Errors when connecting to a computer
Samsung does not see the flash card

The world does not stand still and following the phenomenal success of the Samsung Galaxy s, the even more successful Samsung Galaxy S2 has come. As you can see, from the list above, it inherited the weaknesses of its predecessor - instability to falls and shocks, as well as weakness before moisture and being in an environment with high humidity, which failures are mainly manifested in the failure of charging the phone. ...

This problem is caused by Samsung using a 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 such miniaturization, when a liquid enters the connector area, a short circuit occurs and subsequent "glitches" occur.

This breakdown can be avoided by protecting the phone from water ingress, but if this has already happened, do not hesitate to call us - we will certainly be able to help you with the repair of your Samsung.

Repair Samsung Galaxy S3 (Samsung i9300)

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

Glass breaks
The phone is "always charging"
Center button does not work
Touch keys do not work
Poor signal reception cellular network
Galaxy S3 freezes
I9300 is not seen by the computer

Surely, having looked through the lists of the main faults, you noticed that in all three cases, there are certain malfunctions of the display module - broken glass, sensor not working, not working or poorly working display. All this, moreover, is aggravated by the fact that the replacement of each of these components is associated with the replacement of two other (and when using original spare parts, also several dozen other) components.

But do not blame the creators of the Samsung i9000 / i9100 / i9300 for low-quality spare parts, because all these malfunctions are caused by extremely careless handling of the cell phone, in this case- shock or contact with liquids.

Remember, the performance of your phone depends only on how carefully you handle it, and if the trouble has already happened - do not worry! Just give us a call!
