I am using this ROM for 2 days, only bug's i found are on the:
Storage Settings , when opened , after 2 or 3 second it closes.
and on camera when creating panorama, if you press volume up or down, some flickering is created in front of the picture.
I installed Link2SD and it work's great.
So far no lag detected, my opinion this ROM is better than CM7.2 and stock, it is responsible and fast.
I am using SGA for almost 2 years, and i tried lot's of ROM'S , and after some time using , they get laggy and become unstable.
Only thing i don't understand is why Play store say's that Facebook Messenger is not compatible with this version?
