Wallpaper bug still there where it flickers black after unlocking the screen!!! Grrr. And battery drain is normal due to fresh install
The speaker bug isn’t big thing for me, the only problem is multitasking, so slowly, sometimes when i switch between apps it gets bugy. I noticed in the new update that they changed the 3G icon and Google Now ring is alot better.
