The beauty of android OS is it is fully customisable unlike iOS. You can explore its features and can also add more power to android by using hidden android codes. I guess you are kind of a geek and would love to know about secret codes which can be useful.

Android secret codes can be easily executed by using your phone dialer. There are few codes which are manufacturer specific and others will work on any android phone. The reason behind why these secret codes are not disclosed by manufacturers is they don’t want all of their common users to go on a technical side. Thanks to android developers who make it possible for us to execute secret codes directly from the phone dialer. Using these secret codes you will be able to perform android diagnostics. Here I am listing down a list of hidden codes but all of them might not work for each android device. Try running them on yours to see how many of them work for you.
