I just updated to Nothing OS 2.5.5 update on 8pm yesterday, After this update, I casual watched Motorola edge 50pro and OnePlus Nord CE 4 reviews on YouTube. Then I noticed on that review, Both phone have lagging too much while playing 4KHDR 60fps video in YouTube, and I feels like happy this issue in not exist in my Nothing phone 2a before the 2.5.5 update.
By casually I saw the spiderman movie scenes with 4KHDR 60fps video in my YouTube feeds, then I clicked and selected that resolution, then I shocked that my phone is lagging to much while playing 4KHDR 60fps video in multiple videos in YouTube. I tried uninstalling and reinstalling YouTube, restarting phone and switched to high refresh rate, but all of these there is nothing resolved.
Kindly fix this issue as soon as possible.
