After updating my Galaxy S24 Ultra to One UI 7 (Android 15), I noticed about a 1-second delay before the screen turns off when I press the Side key to lock the phone. This only happens when the display resolution is set to FHD+ (and HD+). When set to QHD+, the screen turns off instantly without delay.
Steps to reproduce:
1. Set display resolution to FHD+.
2. Press the Side key once to lock the phone.
3. Observe ~1-second delay before the screen actually turns off.
Expected result:
The screen should turn off instantly regardless of resolution.
Actual result:
Noticeable delay in screen-off response at FHD+/HD+, but not at QHD+.
Software version: One UI 7 (latest update) on Galaxy S24 Ultra
