Is a 0.3mm thick phone screen protector considered thick? Does it affect the hand feel?

A: 0.3mm is considered a relatively thin thickness among tempered films and is not thick. Reference thickness of tempered glass film for mobile phones: ①0.4mm or more: It is too thick, with a distinct feel and may affect touch control. ②0.33mm: Mainstream thickness; ③0.3mm: Relatively thin, with a good hand feel; ④0.25mm: Ultra-thin, commonly used for curved screen films. It has a better hand feel but slightly weaker impact resistance. ⑤0.15-0.2mm: Water condensation film/soft film, not scratch-resistant. The Woowhead Guanfudun glass is approximately 0.3mm thick. Its thinness does not affect the hand feel and touch control. Meanwhile, the high alumina glass of Nanshan Glass is strengthened three times to ensure sufficient impact resistance (passing the SGS 64g steel ball 1.2m drop ball test). Guanfudun Qu (already on the market) adopts Nanshan Glass's microcrystalline glass KK9, with a thickness of approximately 0.25mm. It is thinner and more suitable for curved screens. The high strength of the microcrystalline glass compensates for the impact resistance loss caused by the thinning. The 0.3mm Guanfudun is 129 yuan per piece and is compatible with the entire iPhone 17 series.
