Great work on the oreo rom! I have been using it since yesterday and I have had no issues whatsoever. Battery backup seems decent on stock kernel. I haven't got the chance to test Bluetooth calls extensively but it seemed to be working in a test call. None of the apps have FCed so far. I'll test it with a custom kernel to see how it fares.
I really like this AOSP version and I hope it is not overloaded with features.
Unstable at all, will wait for the official release
