I spent a while some time ago trying to watch for any modern phone to get full LineageOS support, and eventually just gave up. The closest things came was "partial support for the Galaxy S8, but it will ruin the camera". How much of a future is there here?
Edit: from elsewhere in the thread ( https://news.ycombinator.com/item?id=16460503 ):
> I bought an S8 with the intention of putting LineageOS on it. Sadly to this day there are things not working which are essential, like making calls or using LTE data... or wifi.. or the camera.
(Just to be clear, the Pixel is losing this comparison... it isn't supported at all. But the fact that the Pixel is losing doesn't mean we can say Samsung is winning... this looks more like a loss for everyone.)
Those instructions didn't actually work. Following the only remaining advice LOS has to offer, I went to their IRC channel to ask what was wrong. After waiting more than half a day, I eventually got a response: "no one really talks in here".
Needless to say, I did not get any help.
Oh. My. God. Thank you. Around about the S5/S7 era I stoppped flashing my phone every 5 minutes, but now with my S7 drinking battery fluid every minute of the day I've been wondering where CM had gone.
