About Factory Codes

Almost every device has some features that can be enabled or disabled only by using a factory code. These factory codes, also known as secret codes, are usually very hard to find, because they are meant to be used only by service technicians. Well, I tend to disagree when something really useful has been hidden from the ordinary customer.
You will find a lot of useful Android factory codes in this article, but please follow the provided instructions strictly and be extra careful when you are using the codes. You don’t want to end up with a bricked Android device, right?
To use a chosen code, you have to enter it just like you are entering a number that you want to call, and then press the green “Call” button. Yes, it is that simple.
