The whole device front panel features a high gloss type glass surface and does not offer any kind of anti-reflective coating, huh?

AW: During the development of the Z-E6150, direct comparisons between matte (etched) glass and the high-gloss surface version were conducted. The side by side comparison clearly puts the glossy version in front of the matte panel. The benefit of the glossy version offers higher contrast levels from which text Fonts benefit for improved legibility especially under direct sunlight.
