Android is one of the most complex operating systems we’ve ever seen. Behind the simple interface, easy to use by anybody, there are some secrets though. Developers leave specific ‘backdoors’ in the code, so basically, everybody who has a bit of extra knowledge regarding the way it works can get into the system and exploit Android to the max.
In most cases, these ‘backdoors’ allow manufacturers to troubleshoot the system whenever users are dealing with issues, but they can also be used for gaining access to hidden menus, diagnostic tests or special features and find out as much as possible about a phone.
This can be done through a set of numeric combinations known as secret codes. Since Android is used by a wide variety of manufacturers, there are general codes, working for most of the phones. Still, there are specific ones too, working just for certain brands.
Here you can find a list with all the Samsung, HTC and LG secret codes we know, which you can use to get the max out of your smartphone. Still, please be aware that some of them can have negative effects, so avoid using them if you don’t completely understand what they can do.
