From the beginning when the feature phone was out there, the call forwarding feature was available and many people used to forward the calls on their mobile to other numbers. This feature was useful in so many cases and in the normal feature phone, the setup to do the forwarding was also an easy task, since the Call Forward option was there under the Call Settings which is directly available in the Settings.
But, when Android mobiles came, even though the feature was there, but it was sometime difficult to find out the option because it is not directly available under the Settings. Since the Android OS is an open source software, each mobile phone manufacturer customize the software in their phone, since the layout of each and every sections in the mobile will be bit different even though the functionality and features are the same.
