Want to make your Galaxy Nexus screen appear even bigger than it already is? Then you need to check out this awesome mod created by Rootz Wiki member CurrentWeb. What he has done is create a flashable .zip file that will trick your ROM into thinking your GNex is actually a tablet. This means that instead of having the typical status bar up top and the navigation bar at the bottom of your screen, you will now have the exact same layout as any Android tablet. The nav buttons and status bar will be moved to the bottom, your app drawer and Google search will be up top, and you will have more room to place apps on your home screens. It seems that this would make more sense in landscape mode but actually looks pretty good in portrait mode, too.
There is already a large list of compatible ROMS and the developer plans to keep adding to it. If you are running any of the more popular ICS ROMS right now you will be pleased to see that it is most likely already supported. All it requires is a simple flash over your current ROM and your up and running in tablet mode! The developer is even working on some sort of toggle so that the mod can be turned on or off with a simple reboot. I don’t know about you but I think this is a pretty sweet idea and may give it a go later today barring any major user reported issues. As it stands right now, some ROMs are having a few issues but the dev is looking into all reported problems. If you’re ready to check it out for yourself hit up the source link below.
