You can install Google Launcher as spoke 'chupo_cro', or do better.
The way you spoke of your system I have an idea of what ROM you are using, and recommend to swap it for a cleaner and more stable rom like this here
'lobo_Android'. I tested almost all the roms released for downloads and this was the best.
