disabling all big cores and changing governer works,but cpu0 cannot be disabled so this only works for cpus(4567)thx for kernel,but i have some problem,while changing cpu governer phone auto restarts(happened with R2 too)(using franco kernel manager)
EDIT:unable to find deadline io(only noop and cfq are avaliable). The phone feels so smooth now,used to have some jitters especially after reboot and changing apps,but now it feels super smooth with latest kernel,cheers!
