Android is an operating system developed by Google for mobiles. It endorses the users with a lot of customization features. There are a variety of apps available that enhance its features even more.
In android there are several inbuilt tools that are not visible in the standard mode. There are two methods to access these tools. One is to enter lengthy and complicated codes in the dialer. Each hidden tool has separate code, so it is difficult to manage this way.
The other method to access hidden menus is through an application. HiddenMenus is a small application that provides easy access to all these hidden tools. Another major benefit of this application is that it allows the users to see if Gingerbread OTA for Nexus One is available or not.
