Hidden Secret Codes for Google Android Mobile Phones

When I wrote that article, all secret codes mentioned in the article were working on almost all Android cell phones but with the release of new Android versions such as KitKat, Lollipop, etc, many of the codes stopped working on many Android mobile phones. Also many mobile manufacturing companies such as Samsung disabled those codes so most of the codes no longer work in those mobile brands specially Samsung Galaxy series phones.

But today in this topic, I'm going to share many new hidden secret codes which will work in all Samsung smartphones whether its Samsung Galaxy S series mobile phone or Galaxy Note or any other Samsung mobile model.

I have tested these codes on Samsung Galaxy S6, S4, S2 mobile phones as well as Samsung Galaxy Note 5 and all codes worked fine. I'm sure all these codes will work absolutely fine in all Samsung mobile phones.

I found these codes by decoding and reading various system files of Samsung Galaxy S6 firmware. These secret codes can be used to access many hidden menus and options in your mobile phone to test hardware and sensors, to upgrade firmware and to know about many interesting stuff which are not generally available in phone settings.

If you want to try these useful codes and want to have some fun, check out following list:

NOTE: To use these codes, you just need to open phone keypad or dialer app and type the code. As soon as you finish typing the code, it'll automatically execute and show the required information.



This is a universal code which will work in all mobile phones of any brand. This code shows the IMEI (International Mobile station Equipment Identity) number of the mobile phone which is unique for every mobile phone. Do not show or share your device IMEI number with anyone.



This is also a universal code which will work on all mobile phones. This code shows the SAR (Specific Absorption Rate) limit level information of the mobile phone.



This is an interesting and useful service code for Samsung mobile phones. This code allows you to test LCD, hardware and many other parts of your mobile phone. You might have seen many mobile repair mechanics or service center engineers using this code on mobile phones to test the hardware.


You can test colors, vibration, camera, touch screen, speakers and other sensors on your mobile phone with the help of this code.


This code can be used to know about the software (or firmware) version installed in your mobile phone.



This code can be used to know about the hardware version of your mobile phone.



This code shows the PDA and phone firmware information such as AP, CP and CSC version.

This code allows you to control various diagnostic options such as RAM dump, etc.

This code shows more advanced information about the Camera firmware. It also allows you to update Camera firmware. BUT do not try to use the options to update Camera firmware, it may damage the Camera functionality of your mobile phone.



This code can be used to tweak USB settings on your mobile phone. Do not change the settings if you don't know about them.



This code is used to enter into System Dump mode which can be used to enable fast dormancy and boost network speed, etc.



This code shows the touch screen (TSP and Touch Key) firmware information of your mobile phone. You can also update the TSP and TSK firmware using this code.



This code can be used to reset total call time. Its same as you do in Call log -> More -> Call duration -> Reset.


This code can be used to show and change the Sales code (also known as CSC) of your mobile phone. Do not change anything if you don't know what these options do.

You'll need to replace IMEI string in this code with the correct IMEI code of your mobile phone which can be shown using *#06# code as mentioned above in the article.



This is a very advanced code which allows you to insert Network Lock Control Key code. Do not enter any number without proper knowledge otherwise it may break the functionality of your mobile phone.
