Did you know that you can enter codes into many Android phones in order to access hidden features? These range from looking at information, accessing testing menus, or even resetting your phone. These are simple to enter to – just go to the dialer app, and type in the codes below.
Remember to read and understand the description of each code before you input it, as it is possible to reset your device and cause data loss using some of these codes. Please use responsibly!
We have three lists of codes here for Samsung and HTC phones, provided by a community effort on Reddit. One list of Samsung codes is for later phones like the Galaxy S5 and S4, while the other is for older phones. You may find some codes on both lists.
