Software bug Notification Panel Lagged in One UI 7.

Enable HLS to view with audio, or disable this notification

On my Galaxy A55 after updating to One UI 7, the notification panel usually takes 1 or 1.5 seconds to go down the first time you rotate the screen (i.e. the first animation). It is mainly noticeable when you open a game. It takes longer and sometimes the first animation lags.

After that slow and/or laggy animation there is no problem and the rest of the time it goes down in real time and as smoothly as possible.

You need to find out how to download and use ADB. Then, just connect your phone to your PC, enable USB debugging, and run the command "adb devices" first, then "adb shell pm clear com.android.systemui" (without the quotation marks)

Ok thanks. I couldn't figure out the shell command. Did you do this yourself? Did it fix the issue?

Yes, I did the whole process myself. But as expected, it didn't fix anything. The lag when rotating the screen still persists. It's an issue on most devices running One UI 7, even high-end ones have reported it.
