Easy way to test this:
- take a screenshot where the status bar is visible
- rotate the screen to landscape then back to portrait (do it 5 times so the elements drift for a significant amount of pixels)
- open the screenshot in Samsung Gallery
The status (and navigation) bar overlapping your screenshot should be visible, and you should be able to notice whether the status bar elements have moved their position. In One UI 6 they are static no matter what you do.
Screenshot from S23 Ultra running One UI 6. All status bar emenets perfectly overlap each other, indicating they are static.
Screenshot from Note20 Ultra running One UI 5. All status bar elements are moving, indicating OLED burn in protection is working.
This is bad on OLED screens as they will degrade uneven in that area. I have reported this problem to Samsung, but you should do it as well in order to raise as much awareness as possible so it gets fixed ASAP.
Note: Oddly enough, burn in protection works fine for the navigation bar.
This is why I use goodlock to just hide everything. I had no idea there was burn in protection though. Wish they made it more well known. Imo there should be burn in protection for most static things and it should be a priority for coders. Fkn games that have static HUDS for example.
I play with my Goodluck app and the status bar disappear how to turn it back on.
