For all those that have slight lags on their UI for the G3, you can try this out. Got it from xda-forums...
Seems to be alot smoother and snappier for me.
Onto my settings:
I/O scheduler = cfq
Governor control (with interactive governor) -> hispeed_freq = 1267200
Here are some other changes you can make in governor control for better performance:
go_hispeed_load - change from 90 to 85
min_sample_time - change from 40000 to 50000
target_loads - change from 85 to 80 or 75 (75 = better performance)
NOTE: I have tested my settings for a few days and they seem to be stable. If you want even better performance (at the cost of some battery life) you can try some more changes DON'T use the set on boot option until you're sure they don't cause reboots! Once you deem them stable you should use set on boot with a 30 second delay. Without the set on boot option you'll have to manually reapply your settings after every bootup as kernel settings get set back to default on boot.
NOTE: I've found using the ondemand governor causes reboots.
With these settings i'm not missing art anymore. I've found that setting the scheduler to cfq takes care of most of the lag. Keep in mind that tweaking the kernel for better performance USUALLY comes at the cost of a little battery life. So you'll have to find a sweet spot that your happy with in terms of performance and battery life.
Kindly use Trickster Mod from PlayStore and I believe you need to be rooted.
