Makes the two of us
Tiago and flozd have no problem with frequencies below 600 Mhz but are unstable above 748 Mhz
Whereas my phone is unstable below 600 Mhz .But is still stable at 822 Mhz.
It's a device specific error maybe or not .
These days no one complains or reports bugs ,so how am I to know about them.
Even if you clock it to 744 Mhz and keep the governor conservative you will have the performance of 320Mhz .(Sometimes phones cant scale the frequencies properly )
Try 667-320 minimax/Savaged Zen/performance with vr scheduling .If still it lags
do 600-728 performance with deadline scheduling .
If all fails ,revert to .533 kernel which is 22.214.171.124 not 126.96.36.199 and we will try to fix it somehow .
