actualy I can activate the flashlight in command line.thanks
i don't even know we can take screenshot by power and volume down
and the FXP kernel changelog did't fix the light on ray, other Xperia phones are all fixed~
something like "echo 100 > /sys/class/leds/torch/brightness" to activate
and "echo 0 > /sys/class/leds/torch/brightness"to deactivate.
the miui apllication points to /sys/class/leds/flashlight/brightness
but even when I change this it wouldn't work, but it didn't FC anymore
