Hi guys..i m new to n7000 community..i flashed slimsaber rom 4.4.2 (20140111) and it seems great so far..every thing is working perfect..i just want to know how can i make things a little bigger..i mean i installed spb 3d and all the icons were very small..do i have to change dpi or something or that s the way this rom works?sorry if someone else has asked this again and i missed it..thanks anyway
