Man of Honour
As my OP3 is still going strong, and I can't justify an upgrade (not much jumping out at me as essential on a new handset) I'm toying with the idea of switching over to Lineage OS to keep getting updates, and the like.
Pretty sure that it won't kill my banking app (HSBC), but may screw integration with work apps (MS Company Portal has a fit about unlocked bootloaders and rooting, but I now have a work handset so have an alternative option) so interested to know any other OP3 owners that have moved away from Oxygen OS, how easy it is to load a new ROM and what the experience has been like
I switched to LineageOS about 6 months ago, plenty of guides online that are easy to follow.
Both android pay and my NatWest app both work using magisk to hide root
