UV Glow – Light Effects

UV Glow turns your screen into a soft violet neon light, with a glowing 3D-style flashlight you control with a tap. Get the purple black light look for parties, mood lighting, photos, night-time ambience or just for fun.

Pick a mode, set the brightness and beam, and let the light run for as long as you need. UV Glow is a screen light effect: it makes your display glow in violet and other colours.

Honest note: a phone screen and a phone flashlight cannot produce real ultraviolet light, and UV Glow does not claim to. It will not detect stains, check banknotes, find scorpions or disinfect anything. It is a visual effect only.
