It have apps customized to mdpi/ldpi devices(smaller pics and so on), if im right the current apps that is following with the ROM is just ported directly from other stronger devices which make the apps take more performance because they are customized for stonger phones
hope thats an answer!
BUT! I have also:
I have removed the old lame launcher "trebutchet" and gave you "Apex-launcher" instead(FASTER and more features, you can customize it so it will look exactly the same as trebutchet)
I changed the statusbar, the new one is faster and you have the ability to theme it yourself or remove the themes if you want original.
Please press Thanks
if I helped!
