I will never buy a new OnePlus device again. It's incredible how bad they fucked up everything with the OxygenOS 12 update. "The problems get solved in OxygenOS 13!" well too bad my device doesn't get the update and is just left with a shitty experience.
I have installed a custom ROM but I'm mostly frustrated for my girlfriend whose experience also got much shittier with the update
@jeder You're right. Even though ColorOS is worse than OxygenOS, I (and definitely my gf) could live with the uglier UI. But destroying a working phone with an update? Unbelievable.
@lumisnow after 3 years of trying to deal with it, i just gave up and got nothing phone which has a lightly modified stock android, granted there are no good custom roms, but eh, i can live without that for now
