4.Info

Details about tweaks.

I have tried to avoided all the tweaks that affect kernel bcoz stock kernel users prefer stock only and custom kernel user can retain their original settings.

Recommended tweaks are to enable All and for RAM management - I prefer Balanced

Also to note that when you Tap on tweak - it will apply immediately and also it enable Auto On to apply this tweak after every boot. To disable any tweak just long press on tweak name. Remember that You need to Reboot device to turn off tweaks completely. All the selected tweaks will be auto performed after about 40Sec of rebooting device and you will able to see toast notification about operation. Also notification are will show 'Auto Optimizing' when process is running. It may take upto 1 minute depends on your device status and selected tweaks.
