dareknowak, Mar 6, 2019 : maniparet I got Oxygen OS 9.0.4. The lag issues are gone and now the phone is back to smooth operation......no freezing or lag. However I feel finger print unlock is still slower compared to before 9.0.3 update... No, actually it did not fixed the issue, lag returned after update to 9.0.4. What I've done and what I'm testing is I've cleared launcher cache completely and switch back to classic navigation buttons back home recent. Will see in few days if it solved smth.
