It won't be able to completely remove lens flare and glare from a 'super clear' lens. That's not possible - that's just how light reacts to glass. Even with professional DSLR lenses that cost thousands of dollars still get lens flare and they have the highest quality glass you can get in a camera, so there's no way Samsung somehow magically got some lens to remove it. The reduction of glare/lens flare would have to be done digitally, so I'm guessing Samsung have just tried to improve their flare algorithms, and are using the 'super clear' lens as a marketing tool to try to make the camera sound better. Best way to remove lens flare is to take photos with the sun behind you, don't shoot images directly into the sun or where the sun is visible.
Samsung still have some serious issues they need to fix with the camera though:
- Slow shutter speeds
- Poor indoor/lower light performance (without some night mode turned on)
- Hair/fur detection can get really wonky sometimes and blurred out
- Oversaturation of colours, overexposure of people's faces
If they can tone tweak those things then I think it'd be an outstanding camera.
