Amazing! Eight of the folks here responded in a confirming way to this post. Yet, on my new iPhone 12 Pro Max I've tried watching Youtube videos with the brightness all the way down in a pitch black room and haven't been able to reproduce this flickering border issue. Please provide examples of the Youtube videos you folks are watching and maybe some of the rest of us can try those and see what all this upsetedness is about. One other thing, are y'all sure it's the iPhone that's causing the problem?I can tell you from experience that watching a YouTube video at night and having the borders flicker like a disco party is indeed a problem.
