Hi nikitinahv-RBLX,

Thanks for providing all the details. On the Galaxy A24, when connecting wirelessly to a TV, the phone can switch to Samsung DeX automatically if it detects a display, but DeX is not fully supported on Roku TVs that’s why you’re seeing the DeX screen but without the trackpad or controls.

To fix this, turn off Auto switch to DeX in Smart View settings, then reconnect this will use normal screen mirroring instead.

Sorry. It does not work . Even if i try to open the secret settings menu by tapping on the text or the version.
