Adaptive brightness not working

[DRNA]

The functionality is not working.

Another one that is delivering very poorly is the eye comfort option. Does't adapt and also is not providing the confort needed. Still too much brightness. Needs fixing.

Finally the vivid option vs normal doesn't seem to integrate very well with adaptative mode (which doesn't work anyway). Is lacking more options to make it truly usable. Very disappointing to see so many basic features like these not working in a phone that costs 1k.

Agreed! It seems in some cases, they go one step forward and two steps back.

I am having similar issues with my S25 Ultra. I am finding my brightness rarely ramps up properly in direct sunlight. My old S22 Ultra puts it to shame. I have made a routine and widget to disable all of the extra dim and adaptive brightness off and turn on extra brightness. It only helps minimally. It seems completely random when the screen will decide to brighten up to the level of the S22 Ultra. All of the eye comfort and extra dim settings seem to override the devices ability to go to max brightness, completely different behavior than the S22U. I've got a Moto Edge 2024 that can get brighter on a regular basis than my S25U. Something is seriously wrong with the software. This does not seem to be a bad device as I am on my second S25U due to what I thought was a defect with the brightness. This second one has the same brightness issue.

Thank you for sharing your experience. I also think is the software. I also experience non responsiveness in dark environments. I had to disable facial recognition to try to soften the issue but doesn't improve much.

A 100% software issue. I'm owning a S25 and I had a S25 Ultra for a month before I sold it. Both phones genuine Samsung phones. Both phones behave exactly the same. My issue is with the Adaptive brightness not being able to dial down manually when direct sunlight hits, which causes over-brightness, loss of details on the screen, flickering while taking photos and overall too bright display.

I came to this thread after posting this this morning: https://eu.community.samsung.com/t5/galaxy-s25-series/here-s-a-conundrum-for-you-quot-adaptive-brigh...

The behavior of my old S21 FE regarding the "Adaptive brightness" is miles ahead of the S25/S25 U. So, something was done poorly on the SW side, like many other things that are being messed up lately. Sadly, it's a trend observed by many companies, not only Samsung.
