you can alter the LCD density and use an alternative launcher but you will break a couple things allong the way. If you set 160 you will have access to tablet format of nova, apex, etc launchers but the systemui crashes and you will have no notification bar and no access to settings. Before you can even do this you need to delete phone, dialer, mms apks or you will get caught in a constant run of FC notifications. I switch back and forth, I do not get so many notifications that it really effects me and I prefer the tablet feel. the no settings thing gets to be a pain in the ass though but you can get settings back by alterning your density again.
Settings and system ui appear to fail at around 190 lcd density.
