ObyObed (3q pro)dude same, just go to the boot screen and select safe mode or reboot in my case that same line appears while restarting the phone as i mentioned earlier ,i took a visit to the service center they informed me that this problem will get fixed in the upcoming update,i also mentioned this 2 month’s back in nothing’s community page(this page ). Nothing should really look out for this line problem coz the 3a model’s just got released 5 month’s ago (newer phone’s 🤷🏽♂️),update didn’t fix this problem,nor writing this in the page(community page)the service center guys kept the phone for 3 days,took bug report etc etc but nothing worked @Carl pls take necessary actions, that problem is too annoying dude
