Improve the poor performance of One UI 8.5.
*Posting here again because the One UI subreddit deleted my post again. And it was actually a positive thing for everyone... 😮💨
Guys, as I've mentioned in other posts, One UI 8.5 meant a drop in performance for me, not an improvement. More frequent lags overall and worse performance. However, today I did something some of you recommend, but that I'd never done before.
I decided to download the Galaxy App Booster app and try it out. It was unexpected. After optimizing all the apps and restarting my phone, most of the lag I was experiencing disappeared almost completely. Even the lag in the right panel of the Quick Panel. Now I have a much smoother experience than I did before with One UI 8.5 without using Galaxy App Booster (and that was 13 days after the update). I really recommend it. This is coming from someone who's never believed in these kinds of optimization apps or anything like that.
But give it a try. I'm serious. And let me know how it goes afterward. Don't forget to restart your devices after optimizing all the apps.
