Scratch-resistant, hard-coated surface with 3H pencil hardness. Test winner of the magazine c't issue No. 3 (2012) in a test of anti-glare films. Alongside manufacturers such as Belkin, Folix, Hama, hsw3000, Moshi, and 3M, the dipos anti-reflective film is the only one rated "very good" for glare reduction. Deliberately smaller than the glass back of the Oppo A5 (2020) due to its curvature (see photos), it is bubble-free and can be removed at any time without leaving residue (no adhesive). Easy application - 100% bubble-free installation on a cleaned display! The special silicone adhesive layer displaces air during application and naturally conforms to the display. No impairment of usability! The dipos screen protector provides a pleasant touch experience and is optimized for the back of the Oppo A5 (2020).
