    I've noticed that whenever I go into full screen mode on YouTube. the video has black bars on the bottom, left and right sides. I can't seem to fix the issue with clearing cache, factory resetting and also OS update. Can anyone help?

    Take the youtube app out of the google folder and place it separately on ur homescreen. Fullscreen issue is fixed.that worked for me on oneplus nord. Additionally you can go to youtube app ->setting->zoom to fill screen (toggle it to ON)
