In my case, I have the international 512gb edition, I don't have any of the bugs reported here in various topics. Air triggers, battery life, overheating, dropped frames per second, not charging properly, voice calls, messages, camera, everything works as it should. The only thing I have noticed was the red tone in the notification center with screen put to minimum brightness. I wouldn't even noticed it if I didn't read the post here. For comparison I have done the same with my Note 8 and it has the same symptom. At minimal brightness the screen becomes warmer in colour.
I wonder if I am just being lucky or what? So far as a complete package this is my favourite phone I ever had.
