Okay I managed to get the Auto Brightness and WiFi to work, but the autobrightness is.. working bad, or maybe it's just bad. The screen is extremely dark on a well-illuminated place, and it requires a laarge amount of bright light to raise up the bright, plus the 4.2 camera doesn't put the brightness at 100% when used, which is a needed feature because it gives a real preview of how the photo will look, despite the screen actual brightness. Also, this ROM doesn't have a Performance place where you can switch governors and zram and I/O and all those stuff integrated? Like the 4.1.2 ROM? Those are the main reasons that make me stay at 4.1.2 for now.
