Samsung released a short ad that mocks Apple’s iPhone Duo by simulating the Duo’s adaptive sidebar with a strip of black tape applied to a Galaxy Z Fold8 cover screen.

The Duo’s adaptive navigation system moves user interface elements into a vertical column on the side of the display.

That sidebar has drawn criticism for consuming a significant portion of the device’s screen real estate.

In the ad Samsung places black tape over the Fold8’s cover display, then removes it to reveal how much more content fits without the simulated sidebar.

The clip presents the taped and untaped Fold8 cover screens side by side to highlight differences in visible content.

Samsung published the short ad to target the Duo’s sidebar and to emphasize the Fold8’s cover-screen usable space.
