Don't install Lineage 14.1 20180404-NIGHTLY. It has a bad prank with a bug that can incapacitate your phone. It puts up a modal alert spoofing Google's insecure device warning and declares that it will begin LOSCoins cybercurrency mining. The alert can re-appear continuously so that the phone can't be used.
You can thank these people if your phone is already broken:

Did you read the part where I said that the joke has a bug?
On my Axon 7, the modal window continuously re-appeared every couple of seconds so the phone couldn't be used.
