After updating my MX4 to Flyme 18.104.22.168 Beta, I can’t set home button to home screen anymore, In accessibility for home button there are just 2 options :
Fold keyboard and Return
Also for hold home key again there are: activate smart voice & turn off the screen. Furthermore, there is no option for home screen at Smart Touch.
Both acting like back button in practice, it’s really hard to have just back when you are working with your android…!!!
