The latest EU weekly is just 9.1.3.
There is an early version of "Night mode" in it.
Xiaomi.eu decided to EOL the Max1 then, somewhat earlier than Xiaomi did.
If you want a better "Night mode", you might wait and try the new EU stable 10.2.2.0.
If it has "Night mode", I don't know.
Yes, the Max1 is still a quite good phone, relatively powerfull soc 650/652, only real minus for me is not so good sound.
