Most pointless feature for me. My phone is either in my pocket, on my desk/phone holder in car or charging.
So, if I get a notification the screen will alert me to it or it’ll vibrate/ring whatever. Or alert on watch.
It just sitting there in the desk with the screen lit very dull is just wasting battery for me. If I need to see the time, I can either look at my watch or tap the screen. If I’m actually needing to look at it I’d pick it up and I’ll light up if you will.
I just can’t see a situation where it’s a benefit to have a dull screen on full time? You’re either going to look at the thing or not. Or read the notification. It’s going to distract you either way.
