ALPHA 4
New kernel build
Patched MIUI to build 2.9.14. You can view the changes
Here
Improved performance, everything should be much smoother now
Fixed Light sensor
Fixed Theme force-closes
Fixed Screen flicker when turning on the screen
Switched the default lockscreen to a lighter one to get rid of lag, the regular one is still available in Themes > MIX > Lockscreen if you want it
Probably some other things I forgot
Don't forget to disable GPS and reboot, or else it will be searching for a signal all the time since its still broke.
