You all might find this really stupid or very helpful, but I have been reading all over the web to find the cause of the LED light not working. I've tried the partition wipe, app cache wipes and others, but just a moment ago I was screwing around with the display settings, changing from adaptive to amoled and whatever... underneath the smart stay option, I see LED Indicator and it's selected to off. I set it to on and did a notification preview in my txt app and the LED works now. Hope this helps someone!
