Yes. On mobile, tap the fullscreen button to hide the browser interface where the platform allows it. Tap anywhere on the screen to bring the controls back.

Yes. A maximized white screen acts as a soft key light. Position the display slightly to the side of your face rather than straight on to avoid glare on glasses.

Open the white screen, click the fullscreen button, and turn your monitor or phone brightness up. Angle the display toward your face from slightly off to one side. Straight-on light causes glare and flat shadows. On a laptop it makes a quick fill light for video calls; on a phone it's a handy portable light. Use the brightness slider to dial it down if it's too harsh.

For casual video calls and quick photos, yes. A large, bright white screen is a soft, even light source, and it's free and always on hand. It won't match a dedicated ring light for raw output or color control, but a bigger screen held a bit closer gives softer, more flattering light.
