I have Galaxy S22 Ultra with One UI 6.1 and a Lenovo Tablet y700 I don't know why I can only disable the device screen to prevent burn in on the Tablet and not on my Galaxy phone...Can Samsung please fix this ? I'm using Screen Mirroring not Dex cause Dex don't suppport 120hz...
- The difference in the ability to turn off the device's screen when using Screen Mirroring may be due to the different approaches Samsung and Lenovo have to this functionality. In the case of the Galaxy S22 Ultra, the DeX function allows you to disable the phone's screen, but this is not available when using Screen Mirroring directly. Samsung could potentially add this functionality in future software updates if there is enough demand. You can send feedback directly to Samsung through the Samsung Members app, detailing how important this feature is to you.
In the meantime, a temporary solution may be to reduce the brightness of your Galaxy S22 Ultra's screen to a minimum while using Screen Mirroring, to minimize the risk of screen burn-in.
