171 Secret Codes, Hidden Menu & Dialer Codes for Android – Samsung, HTC, Motorola, Sony & LG Check Codes

What is a Check Code – Secret Codes, Hidden Menu & Dialer Codes?

Android check code or secret code is an alpha-numeric character combination that can give you access to the internal (software and hardware) information of your Android phone. Once you know what kind of information you are looking to access, you can simply type that code in the Android phone dialer to retrieve the information.

There are some generic codes that work on all Android phone variants but some are specific to the manufacturer and make/model of the phone. For example, the manufacturer specific codes for Samsung Galaxy S7 will not work for HTC, Motorola, Sony, Huawei etc.

What are Secret Codes used for?

If you want to find out more about your phone or want to diagnose a problem you will need these codes to access that information. Manufacturers frequently use these codes in their service centres but some of the codes are freely available today.

If you are an advanced mobile phone software developer or mobile phone tester and frequently need to do field tests, improve phone performance or find faults, then these codes will be very helpful. If you are aspiring to be an app developer you will also need to know the codes for quick checks and troubleshooting.

Pros and Cons of using the codes

Like everything, there are pros and cons of using these codes. Please ensure you are aware of them before you use any of the codes so you are well informed.

Pros:

As mentioned in the above list you can test if the phone components like screen, mic, speaker, camera, wifi, battery, GPS you are trying to diagnose are fully working – helpful when you are planning to buy used handset and want to do quick checks

The software and hardware information is readily available on the screen so you can check the phone specs

You can validate the IMEI (International Mobile Equipment Identity) and serial number without opening the phone – helpful if you want to network unlock your phone as this is the key information required to retrieve the unlock code

Cons:

You can access internal working of the phone and can also root your device which might negatively impact your phone warranty

Battery check could drain the battery fully and sometime damage it altogether

What are the steps to use the code?

The most frequently used (universal) code is to “Display IMEI Number” and the corresponding secret code is *#06#. The code is so popular that it works on almost any make/model of mobile phone including iPhones. The IMEI (International Mobile Equipment Identity) number displayed is a 15 digit number that is uniquely assigned to each mobile phone. IMEI number is also asked while buying and selling mobile phones or unlocking your phone online.

Step 1: First open the default dialer that comes with the phone and enter the code – *#06#

Step 2: The moment you finish typing the code it gets executed and the IMEI (International Mobile Equipment Identity) number is displayed on the screen.

Note: The IMEI number is hidden in the above image as is should always be protected for security reasons.

Maintain caution when using the codes

The codes are designed to be used in certain scenarios and only manufacturer specific codes are to be used with their own brand. Mixing the codes with manufacturers and brands can alter the configuration of the phone and cease working. Using the codes without the knowledge or a purpose might cause harm to your phone as well.

Sometime manufacturers will alter the codes based on different model types so depending on the model you have not all code will work with your phone.
