Secret Code in Android

Did you know that android has a secret code? Perhaps from some secret code you have ever encountered on the HP-based java like * # 06 # which is used to check the IMEI on your device. In this article I try to share with you, about the secret code on android (not just the vendor Samsung, but at several other major vendors such as LG, HTC, Sony, and so on. Because several articles on the internet I have met most of the secret code only addresses the vendor samsung).

Here is a secret code that I took from a few forums and blogs on the internet
