Secret codes in Samsung are not needed by most ordinary users, they are intended mainly for engineers and developers. They have to work with such information about the gadget that is not contained in the documentation or in the online manuals on the site. Also, it cannot be checked with a service center consultant. Some of them are available in the phone settings, the rest - only by entering some numbers on the keyboard.
The secret codes in Samsung are a sequence of numbers. Usually they begin with a tone dialing sign - asterisks, and also end with an asterisk or trellis. Between them are numbers and repeated input of the * or # keys. Many Android smartphones, including Samsung, support the same sequence of numbers, but there are those that have unique codes. You can find out which of them are available for this model of tablet or smartphone using third-party applications.
The following is a list of secret codes for Samsung. Some of them are supported exclusively by the latest models, others, on the contrary, are intended only for previous versions of phones.
IMEI
One of the common parameters that must be checked in this way is the international identifier of mobile equipment.
It consists of 15 numbers in decimal representation. Each model has its own unique IMEI. However, there is the possibility of an independent change IMEI. It is used in cell phones of the GSM, WCDMA, IDEN network and some satellite phones. Accordingly, all modern popular phones have IMEI.
Today, this parameter is assigned by the relevant organizations: it helps to fix devices on the network. On a smartphone, it is indicated in several places, which helps to determine whether this phone is legally acquired. You can find IMEI:
- using a combination of numbers * # 06 #;
- under the battery;
- on the package;
- in the warranty card.
One IMEI is responsible for only one SIM card. Accordingly, if the smartphone supports two SIM cards, then it has two IMEI. The first 8 digits are the phone model, the rest are the serial code.
Battery status
Smartphones rarely work for more than three or four days. Often - no more than one day, depending on the frequency of use.
The battery status is easiest to find out - the information is on the screen at the top or bottom. Application stores provide a huge number of programs to check the status of the battery. With their help, you can find out not only the capacity and estimated operating time of the smartphone, but also voltage, temperature, etc.
The same information is easily clarified using a secret code in Samsung. This may be necessary if there is a possibility of incorrect data display.
To find out the battery status, you must enter the sequence * # 9998 * 228 # or * # 9998 * 246 #.
Change display contrast
When changing the weather or time of day for more convenient use of the smartphone, you have to change the brightness and contrast of the display. This is done in the menu settings in the relevant sections.
Changing these parameters affects the speed of the complete discharge of the phone. For example, to extend the operating time of the gadget, the user can reduce the saturation. If you don’t want to delve into the gadget’s configurations, you can use the secret code. For Samsung Galaxy, it looks like this: * # 9998 * 523 #.
Sim card capacity
Understanding how spacious the SIM card used is no longer relevant. Phone book contacts are contained in “clouds,” phone memory, and more.
Sim card is used directly in GSM networks. There are other cards that visually resemble a SIM card. They are used in UMTS (USIM card), CDMA (R-UIM) networks.
The main goal of SIM is to store data about subscribers with which the smartphone user is in communication. She stores:
- phone book;
- list of phone calls;
- SMS
Sims are constantly decreasing. At the moment, the smallest area is nano-SIM, it appeared in 2012. The next largest is micro-SIM (3FF), then mini-SIM (2FF). The largest are full-sized 1FF SIM cards.
Modern SIM cards are designed to the same standards. They are designed for no more than 200 contact numbers, depending on the phone model.
You can find out the SIM card capacity using the secret code for Samsung phones * # 9998 * 746 #.
Vibration test
When the owner of the gadget is not used to the features of the smartphone or is a temporary user, you can test the vibrating alert with a secret code. For the Samsung GT i8350, it is like this: * # 9998 * 842 #.
This will help you remember the type of vibration and respond to an incoming call in time when the phone is in silent mode.
Software version
Software version data can also be found using a secret code. For Samsung Galaxy S4, we introduce the following combination: * # 9999 # or * # 0837 #. This method works the same on all Samsung models. It may be needed when flashing the gadget or finding the right software.
Serial parameters
Each mobile device has a unique serial number.
Its value is a deterrent to theft, because by the serial number you can recognize the device. That is, the mobile device has not only a unique IMEI, but also a serial number.
In some smartphones, these parameters can be changed. For example, through * 0001 * s * f * t #.
Reset user settings
In preparation for reselling or donating a phone, they usually delete all data: photos, tracks, software, contacts. This is easy to do: the menu contains a special section "Reset to factory settings". This will take some time (usually 15 minutes) after which the phone will only contain information configured before it goes on sale.
The same is done using the serial code * 2767 * 2878 #. It is important to pay attention: the method will not help to unlock the phone in case of loss of the PIN code.
