Android OS Not liking the customised user interface loaded on your Android smartphone by your manufacturer? Install the Launcher Pro for free from the Android Marketplace. When you press the homescreen next, it will show the Launcher Pro and other user interfaces. Select the Launcher Pro and tick it as the default UI. Within a second or two, it will be set up as the default homescreen. There is also a paid app available but according to us, the free app works smoothly on most of the makes, including HTC, Sony Ericsson, Samsung and LG.
