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 clarified with a service center consultant. Some of them are available in the phone settings, others - only by entering some numbers on the keyboard.
Secret codes in Samsung are a sequence of numbers. They usually begin with a tone dialing sign - an asterisk, and also end with an asterisk or a hash mark. Between them are numbers and repeated input oforkeys. Many Android smartphones, including Samsung, support the same number sequences, 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.
Below 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.phones.
IMEI
One common parameter that has to be checked in this way is International Mobile Equipment Identity.
It consists of 15 numbers in decimal notation. Each model has its own unique IMEI. However, it is possible to independently change IMEI. It is used in GSM, WCDMA, IDEN cell phones 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 purchased. You can find IMEI:
- using a combination of numbers 06;
- under the battery;
- on package;
- in the warranty card.
One IMEI is responsible for only one sim card. Accordingly, if a smartphone supports two SIM cards, then it has two IMEIs. The first 8 digits are the phone model, the rest are the serial code.
Battery Status
Smartphones rarely last more than three or four days. Often no more than one day, depending on frequency of use.
Battery status is the easiest to find out - the information is on the screen at the top or bottom. App stores provide a huge number of programs to check battery status. With their help, you can find out not only the capacity andestimated battery life, but also voltage, temperature, etc.
The same information can be easily clarified using the 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 9998228 or 9998246.
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 rate at which the phone is completely discharged. For example, to extend the life of the gadget, the user can reduce the saturation. If there is no desire to delve into the configurations of the gadget, you can use the secret code. For Samsung Galaxy it looks like this: 9998523.
SIM card capacity
Understanding how spacious the used sim card is is no longer relevant. Phone book contacts are stored in the clouds, phone memory, etc.
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 purpose of a SIM card is to store data about subscribers with whom the smartphone user is in touch. She keeps:
- phone book;
- list of phone calls;
- SMS.
Sims are constantly decreasing. At the moment, the nano-SIM has the smallest area, it appeared in 2012. The next largest is micro-SIM (3FF), then mini-SIM (2FF). The largest are full size SIM cards 1FF.
Modern SIM cards are designed according to the same standards. They are designed for a maximum of 200 contact numbers, depending on the phone model.
You can find out the capacity of a SIM card using the secret code for Samsung phones 9998746.
Vibrate test
When the owner of the gadget is not yet accustomed to the features of the smartphone or is a temporary user, you can test the vibrating alert using a secret code. For Samsung GT i8350 it is: 9998842.
This will help you remember the type of vibration and respond in time to an incoming call when the phone is in silent mode.
Software version
Data about the software version can also be found using the secret code. For Samsung Galaxy S4, enter the following combination: 9999 or 0837. This method works the same on all Samsung models. You may need it when flashing your gadget or finding the right software.
Serial parameters
Each mobile device has a unique serial number.
Its value is a deterrent to theft, because the serial number can be used to recognize the device. That is, the mobile device has not only a unique IMEI, but also a serialnumber.
In some smartphones, these settings can be changed. For example, through 0001sft.
Reset user settings
When preparing to resell or donate a phone, all data is usually deleted: photos, tracks, software, contacts. This is easy to do: in the menu there is a special section "Reset to factory settings". This will take some time (usually 15 minutes) after which the phone will only contain the information configured before going on sale.
The same is done using the serial code 27672878. It is important to note: the method will not help you unlock your phone if you lose your pin code.
