Samsung did not fix the scrolling lag in stable release.

[ruskin]

We have posted on this community numerous times stating that there is a bug with the adaptive refresh rate dropping from 120Hz to 60Hz when scrolling through any app, and Samsung decided not to fix this and push it out on "stable" release of One UI 4. This issue makes the phone feel extremely laggy when scrolling, since the display will stay at 120Hz ONLY when your finger is still on the display. As soon as you lift your finger the refresh rate drops to 60Hz leaving the scrolling animation to appear very laggy/sluggish. This should have been fixed by now and definitely should have not made it to final release. Where is the internal testing on this one?

Known issue

I suspect Samsung decided to not include it, though they stated it would be in GA

What reason could Samsung give to justify not including a patch for this issue? It will severely degrade anyone's first experience with One UI 4 because their phone will feel slower/laggier than before. Even if it took Samsung another week to release stable One UI 4 to fix this, they should have done that.

we know there's a reason, just not likely a good one

That is Only USA Galaxy S21 models seem to be affected https://www.sammobile.com/news/android-12-on-the-galaxy-s21-has-a-lag-issue/

In the interim, you can grab the Galaxy Max Hz app from XDA to force 120 Hz always (when the screen is on). It hasn't affected battery life for me and has 90% fixed the issue for me.

However I don't want to have to rely on a third party app/hack to fix such a basic, fundamental feature.

Reminds me of One UI 1's (official release) for my S9+. Its tendency to freeze and involuntarily play my music on the loudspeaker with my headphones plugged in.. volume buttons, power, everything was locked in the process.

That embarrassed me so many times in class.

QA should have higher standards

Hello @ruskin ,

We are very sorry about the 120Hz issue still being present on official update. We have put in fixes to help with the issue in official software BUK7 but some users are still experiencing this issue. we have escalated this issue internally as impact is for a large amount of users. 

Regards
One UI Beta Team
