I haven't figured out the volte thing yet, it might be working. I don't even know what that is lol, but I do know I have video calling now. That's totally wicked!!! I have been using the nougat kimcii kernel (I think I'm saying that right) for about a year now. I tried Oreo, did not like it at all. Went back to 7.0 after less than a week. I did not want to go to pie, but my rom was starting to mess up pretty bad - lost all messaging capabilities and no amount of formatting/factory resets were going to fix that. I trusted the opinions of my peers and gave this a shot. HOLY SMOKES!!! Dude, I love this rom! In the words (somewhat) of another poster: I can't believe everyone isn't using this rom. I can't even tell you exactly why, I have it set up to look exactly like my old rom. Maybe it's because of all the bonus tweaks. And it's so responsive.. And it's so easy to cut apart my apps with other apps and rearrange them without my phone having a major breakdown. Installed magisk, su, lucky patcher, and it all is working flawlessly. No matter what I've done so far, it's all been exceptionally easy, and everything just works. I can even get rid of the voicemail notification. And for some reason, it just looks nicer. Again, the little things. Very well done, major props. The best custom rom I've used in ten years.
