The need to ROOT your android device:

              Apps get installed automatically on phone memory. Some developers give the feature to move apps to sd card but it is possible in only 2.2 + android versions only. To move all apps to the sd card the process of ROOTING is needed to be done.Also ROOTING voids your 1year warranty. Though you also can UNROOT your phone.
