@jaganbv, @Divyesh49 and @SpaceDye, If you all want to use Official LineageOS 15.1 so badly then you can give a try to the Unofficial LineageOS 15.1. I am sure that you won't be disappointed on using it . It's pretty stable and can be used as daily driver. I myself have been using LOS 15.1 as my daily driver since a few months.
@SpaceDye many people are happy using Unofficial LOS 15.1.
Yes, and many people are happy with Pepsi instead of Coke. Not saying the unofficial release is bad, I have tried it a few months back and it seemed stable enough, but some of us just want the extra peace of mind that comes with an official release, i.e. timely updates and better QC.
