Great ROM. Really smooth.

Everything works fine but backlight does not turn off in lock screen.

PS: Facing same issue with your HalogenOS build too.

I also faced the same issue. The backlight used to remain on which caused some battery drain, I couldn't increase/decrease the brightness and also auto-brightness sensor didn't work.

To solve this, I clean flashed without locking bootloader to official Nougat MIUI Global Beta ROM and then after flashing custom recovery; wipe system, cache, dalvik cache and data via recovery if you don't want to delete internal storage files and lastly flash the ROM . If you want to save your internal storage files, just select save userdata instead of clean all in Mi Flash Tool.

If you still have the problem, repeat the same but first flash Marshmallow ROM, then the Nougat ROM and lastly the custom ROM. I think this issue arises due to some kernel incompatibilities with the custom ROM.

Welcome! I know that's tricky but to get something good, you need to work a bit to achieve it!
Did the hotspot tethering and USB tethering bugs are fixed in the latest build?

I don't use them, so no idea.

But flashing 3 ROM just to try a new ROM is too much work for me.

I don't get this line "are not running stock crDroid-kernel". Did xiomi release redmi 4a kernel source? Anyways is it possible to know if this rom has the nougat battery mode shown. The one I'm using right now has only the default mode.Would switch to this If I can set the mode myself for example to ultimate battery mode.

Thanks

I had tried an older unofficial build of crDroid earlier. It had the the battery mode as far as I remember. The battery mode consisted of 5 modes starting from powersave mode which at default gets enabled when the battery saver is turned on then efficiency enabling the battery optimisations, balanced for normal users, quick mode and lastly the performance mode but I still doubt that it works or not because for all these, the system needs kernel optimisation to be performed and still now the kernel sources has not been yet released.

If your device is rooted, I can suggest you to try Kernel Adiutor to check if your device goes into deep sleep mode when the device is not used. If your device doesn't goes into deep sleep mode then try some doze apps like Greenify, ForceDoze etc.

How to do that? Sorry for my ignorance as I don't have experience flashing firmwares.
