I have problem on latest 9.10.31.
Every reboot I feel like blue light filter activates by itself, the colors are much darker.
After I lock and unlock screen problem is gone to next reboot.
Can't make ss, because this isn't visible on screenshot....
And no, this isn't about auto brightness.
NEVER EVER lock bootloader after flashing custom ROM!
Lock bootloader only after flashing Pure Stock ROM for Mi A2
Also if you want to install ROM other than miui first flash Mi A2 Stock ROM on your device.
There is new official TWRP version for whyred which now works with miui pie.
ROM has nothing to do with this.
EDIT: They included red wolf in zip. That's why recovery will be replaced after flashing this weekly.
