Secret Codes List for Samsung, HTC, Motorola, Sony, LG And Other Android Devices
Secret codes are implemented by manufacturers into just about any devices. It is a most useful method to diagnose the gadget without having to rely on a computer connection that may not be available at the time. Every manufacturer has its own list of secret codes though for Android devices some work no matter the provider.
Redmondpie has considered to supply a list of secret codes that work on most devices from the major Android smartphone manufacturers. The codes are usually entered by bringing up the dial pad and imputing the code. The last symbol should take you right into the designated menu. Though a majority of codes apply to most handsets, some are provided for a specific brand, like for the Motorola Droid.
Some codes will give you access to more sensitive device settings. It is not something you want to tamper with as you can be left without a network connection or WiFi. Be sure to remember every setting before you change it. Other codes will factory reset your device. There are also the most useful ones for testing some of the device’s hardware features, such as the screen or sound and vibration. If you think there is something wrong with your device you may want to use those. Here is the list and be sure to read carefully before inputting any code:
