[Xiaomi Redmi Note 4 Questions & Answers] DarthJabba9:
Ok, below is a list of the Oreo ROMs that I have found on this forum (sorted alphabetically).

While it is wonderful to have such a rich variety, the array of choices is bewildering. How does one choose? I guess one should start with the ones that are absolutely rock solid, stable (i.e., everything works as it should - especially things like bluetooth phone calls) and with no serious bugs. Then proceed to features (in terms of leanness versus customisation potential).

I note that most of them are based on AOSP/LOS. I myself would prefer an AOSP-CAF based ROM. Isn't there any that is based on AOSP-CAF?
