Service codes for Samsung phones

Samsung X460 find out the software version dial *#1234#

Samsung X460*#8999*8378# — engineering menu

Samsung X 100*#8999*8378 — volume code

Increase the volume of the melodies.

Dial *#8999*8378#. In the “test mode” menu, select item 2 “H/W Test” - item 2 “Audio Settings” – item 3 “Melody Strengthening”, then: I recommend setting melody level 1 to 0 (so that there is generally silence and vibration at a minimum), click “save.” to Melody Level 5 (i.e. 4 times) and set to 31 (does not react to more), again “save.” and that's all. The ringing becomes noticeably louder (from 24 to 31). (We used this method to increase the volume of the speaker on the back of the phone.)

Option 2: Increase the speaker volume. Dial *#8999*8378#. In the “test mode” menu, select item 2 “H/W Test” - item 2 “Audio Settings” – item 4 “Speaker Volume”, then: item 1 “Normal” - set the volume of speaker 5 to 63 (does not respond to anything higher) . Click “save”. Now we can hear our interlocutor much better. (And this method was used to increase the volume of the speaker on the front side.)

The other day I was dealing with a phone whose touch panel did not work, or rather the lower left corner did not work correctly in some applications.

I go to the menu - everything works fine. I start writing SMS in a standard keyboard - the lower left area with symbols does not work. And then I remembered that Samsung has many service codes on smartphones, including self-testing ones. I immediately decided to write a post about service codes, which I often use when diagnosing Samsung phones.

ATTENTION!!! Before starting software updates, rooting, resetting settings and other manipulations with your own or, God forbid, someone else’s device HIGHLY RECOMMEND read this one. In short, you have been warned and don’t say later that this is the first time you’ve heard this.

We test it ourselves - Samsung GT-I9300 Galaxy S3

*#7353# - This is the first service code that I want to consider in this post. By typing it on the keyboard on the phone, we will go into the so-called testing mode, which allows you to test the basic functions of the smartphone. Let's go over all the points in more detail:

Rice. 1: *#7353# - Menu for testing basic functions.

Melody- Checking the speaker - plays sound.

Vibration- Checking the vibration motor - the device vibrates periodically.

Speaker- Polyphonic speaker test - plays sound.

Dimming- Screen dimming test - the screen dims.

Camera- Checking the main camera - switching to photo mode with the main camera.

VT Camera- Checking the front camera - switches to photo mode with the front camera.

Bluetooth- Bluetooth turns on and searches for devices.

TSP Dot Mode- Checking the touch panel “spot mode”. On the screen where you touch touchpad a cross appears.

Rice. 2: Barely visible crosses where touched.

TSP Grid Mode- Testing the touch panel “grid mode”. The image on the display is divided into many rectangular areas. If the area reacts to touch, its color changes. To successfully complete the test, each area must respond.

Rice. 3: Grid mode.

Accelerometer Sensor- Checking the operation of the accelerometer. Allows you to change the orientation of the image on the display depending on how the user holds the device. In addition, many functions can be controlled. For example, shift music track simply shaking the case, receiving calls, etc. Testing the auto-rotate screen function. The image flips depending on the rotation of the body. The arrow always points up.

Rice. 4: Vertical arrangement.

Rice. 5: Horizontal arrangement.

Proximity Sensor- Checking the proximity sensor. Applicable only to phones with touch screens. It tracks the distance from the device to the user’s face, and when it comes close, it automatically blocks the screen sensor. Thus, you can safely put the device to your ear during a conversation, without fear that the phone will perceive touching the screen as a command. Placed on the front panel, usually above the screen. If the phone is not attached to the ear, then the display will read “Release”, otherwise “Working”. You can easily check the functionality of the proximity sensor by covering it with your finger or pen.

Rice. 6: Release.

Rice. 7:Working.

Light Sensor- Checking the light sensor. A sensor that monitors the level of external light. Allows you to automatically change the screen brightness depending on external conditions - for example, for working in twilight, the minimum brightness may be quite sufficient, while in the bright sun the maximum is necessary. Thus, you can achieve not only the most comfortable level of brightness, but also significant savings in battery power - after all, without high brightness, which is not always needed, the screen consumes more energy. Placed on the front panel, usually above the screen. In good lighting, the screen displays 1, in poor lighting, 0. To quickly check, place the phone under the lamp (1 on the display), cover the light sensor with your hand, 0 should appear on the screen.

Rice. 8:Good lighting.

Rice. 9: Bad light.

*#0*# - This is the second service code, which we will also consider at Samsung smartphone GT-I9300 Galaxy S3. Has the following points:

Rice. 100*# - Test menu.

Red Green Blue- Testing the display for displaying RGB model colors The image changes its color (Red - red, Green - green, Blue - blue).

Receiver- Checking the speaker. The speaker plays sound and the picture turns white.

Vibration- Testing the vibration motor. The device begins to vibrate.

Dimming- Screen dimming testing. The screen goes dark.

Mega cam- Checking the main camera. Switch to photo mode with the main camera.

Touch- Checking the touch panel. The image on the display is divided into many rectangular areas. If the area reacts to touch, its color changes. To pass the test, each area must respond.

Rice. eleven: Checking the touch panel.

Sleep- Testing the sleep function - The device goes into sleep mode.

Speaker- Checking the polyphonic speaker. Starts playing sound.

Sub key- Testing sub buttons (menu, central, return). After clicking on one of the sub buttons, the image changes color.

Front cam- Checking the anterior chamber. Switch to front camera photography mode.

LED- LED indicator testing. The indicator lights up red (RED), after touching the touch panel it changes color to green (GREEN), after another touch it lights up blue (BLUE).

LOW FREQUENCY- Checking the speaker for sound reproduction low frequencies, there are three frequencies to choose from (100 Hz, 200 Hz and 300 Hz).

Rice. 12:LOW FREQUENCY.

Sensor Menu- To test the main sensors:

Rice. 13: Sensor testing.

1. Accelerometer sensor(accelerometer). x-angle, y-angle, z-angle – values ​​of deviation angles from the axes of a three-dimensional coordinate system (0 - 90 degrees), ACC Raw Data – their values, recoded into the decimal system (0 - 1023). IMAGE TEST - testing the screen auto-rotate function. The image flips depending on the rotation of the body.

2. Proximity sensor(proximity sensor). At a distance of the device from the user's ear approximately equal to 3cm. the proximity sensor is triggered. PROXIMITY: 0.0 – the sensor did not work. PROXIMITY: 1.0 – the sensor has triggered. The ADC parameter has values ​​from 0 to 255, 0 – the object is at the farthest distance from the sensor, 255 – the closest. When ADC = 15 the sensor is triggered.

3.Barometer sensor(barometer). A barometer measures atmospheric pressure. BAROMETER – atmospheric pressure value, hPa - hectopascal (102 Pa). ALTITUDE – altitude above sea level. Barometer Selftest – barometer self-test mode; if the value is PASS, then the test is passed.

4.Lights sensor(light sensor). Light sensor – illumination value (lux). At night on a full moon, the illumination is 0.2 lux, sunrise in clear weather is 1000 lux. There are 4 levels of lighting: level 1, level 2, level 3 and level 4. Level 1 corresponds to poor lighting, level 4 to good lighting. levels 2 and 3 are intermediate between levels 1 and 4.

5. Gyroscope sensor(gyroscope). The gyroscope tracks the speed and direction of the mobile phone's movements in space. Somewhat similar to an accelerometer, it provides enhanced control capabilities that can be useful, for example, in games. Y, P, R – rotation angles around the Z, Y, X axes, respectively. Gyro Selftest - self-test mode, if the value is PASS, then the test is passed. Graph – graphical testing mode.

6.Magnetic sensor(magnetic sensor). AZIMUTH, PITCH, ROLL – values ​​of angular deviations. Selftest - self-test mode, if the value is PASS, then the test is passed. The black circle with an arrow is a compass, the arrow points to the North Pole of the Earth.

*#0228# - Battery data.

Rice. 14:Battery condition.

Voltage– voltage value at the battery contacts. After setting the device to charge, the Voltage value begins to increase, so this code can be used to check the charging function. Temperature – battery temperature value.

*#0283# - Microphone testing.

Rice. 15:Microphone test.

RCV Packet Loopback ON– the sound from the microphone is played through the earpiece.
SPK Packet Loopback ON– the sound from the microphone is played through a polyphonic speaker.
EAR Packet Loopback ON– the sound from the headset microphone is played through the headphones.
Packet Loopback OFF– disable microphone testing.

*#0842# - Vibration motor test.

Rice. 16: Vibration motor test.

on– the device constantly vibrates;
off– the device does not vibrate;
auto– the device vibrates periodically.

Other service codes that I often use.

*#12580*369# - Checking the motherboard calibration history. RF cal - calibration date; if the date is missing, the board is not calibrated.
*#0782# - Examination set date and time. Allows you to check the watch quartz.
*#06# - IMEI check.
*#1234# - checking the software version. Warranty repairs require updating device software to the latest version.
*#2222# - checking HardWare software version.
*#2767*2878# - custom reset. This is a reboot of the device, during which the user settings will be reset to factory settings, but the data will be saved.
*2767*3588# - full reset. This is a reboot of the device, during which the system’s factory settings are restored and all system information is cleared, including installed programs, contacts, and SMS. Deleted information cannot be restored. Data located on memory cards and SIM cards is not deleted.
*#87976633# - factory reset. Reset is used on devices based on Android OS.

To use service codes on phones with OS Windows Mobile and tablet PCs without a GSM module must enter the service code dialing mode.

##634# - phones based on Windows Mobile OS;

Tablets without GSM module (type in calculator):
+32286798378+ GT-P7510, GT-P7310.
+30012012732+ GT-P5110, GT-P3110.

Preconfiguration

For some phones, after updating the software, you need to perform preconfiguration - specify the region (SER or Russia) to which the phone belongs. If this is not done, then there may be problems with SMS, searching in the phone book, and some standard applications may be missing.

For phones on the UMTS platform (for example, S5230, S5250):
*#5239870*# in the menu that appears, select pre-configuration, enter *#27236*# , select SER.

For Agere platform phones (eg C3011, C3530, E2232):
*#272*HHMM# Select SER from the list that appears. HHMM is the time on the display at the current moment.

So we found out how you can test the Samsung GT-I9300 Galaxy S3.

P.S. If you encounter any errors during the firmware process or the device does not want to be detected by the computer at all, read this. It describes typical problems and errors that novice users often encounter.

Far from masking inescapable secrets, the latter allow the exploration of functions usually reserved for constructors, or even for operators who would like to change a precise parameter through certain secret codes. For the average user, the interest is often insignificant, but the hackers we love to open up to the depths of our precious technological jewelry.

Before you "have fun" with all these little wonders, some minor usage details. Keep in mind that some of these commands may change the behavior of your smartphone, while others may simply. On the other hand, codes sometimes depend on the smartphones used or even on the operating system versions. One last piece of advice to avoid all disappointments.

A tricky situation, or something wrong with the memory again

From this point on you should read more carefully. Did the title alert you? However, as long as your phone is reset in a standard way, you are not afraid of the threatening consequences of ingenious methods. But probably such a well-known phenomenon as “glitches”, which you may have repeatedly noticed in the operation of your device, somehow should have alerted you. Therefore, information about existing options for returning a “lost” phone will not be superfluous for you. So how to reset Samsung settings so that the phone is not damaged, and the “sound mind” in the device becomes clearer? You won’t believe it, but it’s quite simple, and it will take very little time.

Codes for testing the main components

To use it, it couldn't be simpler, just open the phone calling app and enter the codes as if you were dialing a phone number. The execution must be done in a step. The following secret codes are used to test the components of your smartphone or tablet. These are basically diagnostic tools designed to identify the source of potential failures. These commands may be useful for aftermarket service or manufacturer repairs.

This last batch is probably the most sensitive to this file, but since you followed all of our recommendations at the beginning of the file, you are not taking any more serious risks. Of all these little codes, it's likely that only the handle is functional. It is impossible to answer this question with certainty without trying it yourself. We wish you a good test.

Why does the phone start to glitch?

Given the compact size of the mobile device, the internal filling of the device has extremely limited space. The motherboard of an electronic device is literally “studded” with various microcircuits, modules and parts. Microelectronics is a rather complex applied part of science. Magnetic fields, potential differences and many other factors of an electrical nature can be the “causative agents” of the symptoms of a phone malfunction. Resetting Samsung settings can partially resolve the problem situation associated with the partial inoperability of an individual means of communication. More serious preventive actions can only be taken by specialized centers, private workshops, or self-taught people with an incredibly practical background of experience. So what becomes the main reason for the sometimes protracted “fits” of our irreplaceable friends of communication?

Do you use some of these codes with your smartphone or do you prefer to go through more intuitive menus? Technically it sounds like it's about hacking, but it's not, secret codes are not designed to hack smartphone software.

Today these secret codes are no longer a secret because of a news leak. Another reason for using these codes is that you should use them to start your device and not to get tricks and connect your phone's settings control panel.

Four main culprits of electronic “mindlessness”

• Reason one. Mechanical damage, which results in displacement of microcircuits and tearing of parts from the soldering site.
• Probability number two. Oxidation of motherboard components after exposure to liquid or condensation.
• Option three. Systematic overload of the phone's flash memory and extremely intensive use of the device: frequent battery jerking (SIM card replacement), incorrect disconnection from service programs.
• The most nasty culprit number four is a virus that got in God knows how!

Universal code to reset Samsung settings

So, sometimes a certain combination of numbers is quite capable of coping with temporary “glitches” of the phone. But it is important to understand what symbols and numbers you are entering, and what they are intended for in general. Sometimes an incorrectly used service command can completely destroy not only user settings, but also the entire software part of the device. Therefore, before using the code kindly provided, make sure that the source is reliable. And now about the main thing. The first service team presented is not always effective, however, your device may fall under the successful percentage of results, especially if the year of manufacture is not the first, so to speak, fresh. Dial -*2767*2878# on your Samsung keyboard and press the “call” key. The device should reboot. But partial or complete loss of information stored in the mobile memory is possible. Therefore, if technically possible, save at least the phone book. Otherwise, if you urgently need the integrity of subscriber contacts, it would be more advisable to contact a specialized workshop. There is another code that can snatch an electronic organism from oblivion, this is *2767*3855#. This set of numbers will certainly perform a complete reset of the Samsung device, as it is effective in use for most devices of the Korean manufacturer.

To correct mistakes. This software has been specially designed for non-technical users. Can't disable it, access it and it won't work properly? There are three very simple procedures, each of which involves deleting personal data and how much is stored on your device, so you should save it all with backup copy before proceeding with the reset.

We recommend that you always remember to back up before resetting, as otherwise everything you have will be lost. Settings Menu: The first recovery mode starts with the settings menu. On the Settings screen, simply tap Backup and Reset. By default, the device automatically backs up and restores all data inside the device. However, you can uncheck the box to not restore data from the backup. Clicking "Reset Factory Settings" will reboot your device and "Erase everything" will complete the procedure.

What should I do if my Samsung is Android?

If the standard functions of the smartphone and the applied service code *2767*3855# have no effect, resetting the settings provided in the Samsung Galaxy Y system itself can be done using a fairly effective method.

1. Press and hold three keys of the device, in the described sequence: first the “volume +” button, then “Home” (central navigation) and close the sequence chain with the “on” button.
2. After the phone opens the “Recovery” menu, select “Reboot system now” and press “Home”. After the reboot, you can assume that the phone has just come from the store.

Congratulations to you! Now you have not only several ways to return the “prodigal” phone to working capacity, but also have become the owner of valuable information. Perhaps you will have the opportunity to prove your user competence and help someone at a time of difficulty beyond their ability.

Key combination. The second method involves clicking on a key combination. Then you must select the option “Delete all user data”, always confirming with the “Power” button. At the end of the reset, the device will show the message “Restart the system now.” The phone will reboot and delete all existing data. Therefore, in this article we have seen. When this is done, your smartphone will be both new and purchased, restoring all system default settings. This will correct errors and problems.

We remind you again about backup before proceeding with recovery, otherwise all your data will be lost. Just follow a few simple steps. In this article, we better understand what they are and what the risks are associated with using these codes. In practice, the code in question is a combination of asterisks, hash characters and numeric characters that, when entered, go, that is, go to restore the phone to factory settings, erasing all data from it.

Samsung mobile phones are often released on operating Android system, therefore it is assumed that the appropriate codes can be used. Special digital combinations allow you to get the desired access to functions that most often do not work when the phone is locked and only an emergency call is available in the shortest possible time and without unnecessary worries.

Secret codes allow you to use the chance to successfully solve existing problems with mobile technology.

Secret codes: what are they?

Secret codes, also known as engineering or service codes, are an opportunity quick access to various smartphone functions. As a result, even hidden functions become available.

Recently, mobile phone users have been testing the Secret Codes program in practice. The application is capable of successfully scanning the operating system for the presence of service digital and symbolic combinations, after which it will provide the result in the form of a list. You will have to click on the option you are interested in and use its function.

Unfortunately, the Secret Codes program is not always available or does not demonstrate the full level of functionality, therefore it is recommended to take care of your personal knowledge of the list of codes.
