In this guide, we will cover the top 15 Android secret security codes you need to know that you can try on your Android smartphone.

What Are Android Secret Codes?

Secret codes are essentially short number combinations that activate hidden features when dialed on your phone's dial pad. Android engineers use these codes during testing and development, but they can also be highly useful for regular users. The codes grant access to things like usage statistics, wireless tests, hardware tests, and advanced reboot options that are not available through your normal settings.

How to Use Android Secret Codes

Using these Android codes is simple:

1. Open your phone's dial pad or the phone app

2. Input the specific code as you would a phone number

3. Press the call button

4. Follow any additional prompts that appear

Of course, you should exercise caution and only use codes that you fully understand. Certain codes can alter your system or erase data if misused.

Now let's explore the top 15 most helpful secret codes for Android phones:

1. *#06# - IMEI Number

Your phone's IMEI or MEID number is like your device's fingerprint. Dialing *#06# displays this unique 15-digit number that identifies your specific device model and manufacturing details. Knowing your IMEI can be important for troubleshooting, especially if you need to provide it to technical support or your carrier. It also helps to identify lost or stolen devices.

2. *#*#4636#*#*- Testing & Usage Statistics

One of the most useful codes is *#*#4636#*#*. Inputting this code opens a detailed testing and usage menu.

3. *#*#7780#*#* - Factory Reset Your Device

Use the code *#*#7780#*#* to perform a complete factory reset, erasing all data and resetting your phone to default settings. This essentially reverts your phone back to its out-of-the-box state. Only use this if you plan on selling, exchanging, or giving away your phone and want to wipe it clean.

4.*2767*3855# - Completely Format the Phone

For an even more thorough data wipe, input 27673855#. This will completely format your phone, erasing absolutely everything including your OS, apps, and SD card data. This makes it impossible to recover any previous data. Only use this if you have no need to keep anything on the device.

5. *#*#34971539#*#* - Detailed Camera Information

As a photography buff, one of my favorite codes is *#*#34971539#*#*. Dialing this provides in-depth usage details about your rear and front-facing cameras. You can view the camera firmware version, see the max megapixel values, and check what modes are supported like HDR, panorama, and flash.

The code ##273283255663282*## creates a backup of all your media files. It backs up photos, videos, and music files from internal storage and your SD card to a hidden partition. This allows you to restore your media if you lose data or wipe your phone.

8. *#*#232339#*#* - Wireless & Connectivity Test

Diagnose your wireless components using *#*#232339#*#*. This activates a comprehensive test menu for things like Wi-Fi, Bluetooth, GPS, mobile data, vibration, proximity sensor, and more. You can test each function individually and even view signal and connection details.

Having display issues like dead pixels? Run a pixel diagnose with *#0*# This brings up a colored screen allowing you to inspect your display for faulty pixels that are always on or off. Use this before getting a screen repair or replacement.

10. *#*#0842#*#*- Backlight & Vibration Test

Quickly test your vibration motor and backlight with *#*#0842#*#*. You can turn vibration on and off and adjust your screen's backlight intensity. This is useful for ensuring your phone's physical feedback components are functioning properly.

11. *#2263# - Band Selection Menu

Having signal issues? Dial *#2263# to open the band selection menu. Here you can force your phone to connect to specific mobile data bands like 3G, LTE, and more. Toggle between bands to identify which provides the most stable service in your area when you are experiencing connection problems.

12. ##0673## or ##0289## - Audio Test

Having microphone or speaker issues? Use either ##0673## or ##0289## to initiate an audio test. This plays various tones allowing you to verify both the speaker and mic are functioning properly on calls and media. The code cycles through low, high, and mid frequency tones on your speaker, headphone jack, and mic.
