It's the 2nd of April and still no One UI 6.0 update for me in South Africa. I'm very disappointed. My Galaxy Tab A8 got the update this past weekend. How is it that a 2 year old tablet gets the update before a device launched last year?
Mine did that too, I tried using the "Light" profile but I found that if you use the "Standard" profile for a while it gets better over time. I think the phone making apps sleep helps it.
