I use this on my Nexus 6P and it's surprisingly great! The only app that I really need that I have problems with is Lyft, but other than that everything I need works smoothly. I get as many apps as I can from F-Droid and use Yalp Store to get the rest. Preferring F-Droid apps also means I have fewer apps that expect Google Play Services.
Up until now I wasn't aware microG was doing their own builds for Lineageos, when did that start? I'm quite happy to see that, it'll help a lot of people. I'd still rather see a world where custom builds aren't necessary.
I so desperately want to use MicroG, but keep having to go back to the official framework. The handful of apps I use that rely on Play (Lyft, Transit App, One Bus Away) all insist the Play Framework needs to be updated.
MicroG has been picking up steam. They're doing OTA updates of Lineage + MicroG now.
