Screen Protector 3D AR with Applicator PRO, for iPhone 17 Pro Max

Flat 2.5D glass has only a slightly rounded top edge and ends just short of the curved edge of the display. On an iPhone with rounded display edges, this leaves a narrow uncovered strip around the perimeter. The 3D glass is shaped to the same curvature as the display and covers it right up to the point where it meets the phone's frame. Full-surface coverage makes sense especially on a phone without a case or with a thin case, where flat glass would leave the edges of the display exposed.

The top Nano AF oleophobic coating repels grease from your fingers, so fingerprints cling to the glass less and wipe off easily. The effectiveness of the coating is described by the water contact angle: on new glass it exceeds 115°, which means water and grease stay in droplets and don't spread across the surface. Durability is verified by an abrasion test in which the surface is repeatedly rubbed with steel wool; even after 10,000 cycles the glass keeps a contact angle above 105°, so its ability to repel fingerprints lasts even after months of everyday use. As a result, the display gets fewer smudges and wiping it with a cloth is quicker.

The Corning glass goes through a double-ion exchange, which creates a layer of compressive stress in the surface that resists crack propagation. The surface compressive stress (CS) reaches 820 to 890 MPa, whereas the usual standard is above 800 MPa, and the depth of the ion exchange is 16 to 19 µm. At a glass thickness of just 0.33 mm, this treatment passed a drop test with a steel ball weighing 64 g from a height of 120 cm. Chemical strengthening therefore increases resistance to impact and cracking, not just to scratching.

The glass transmits at least 91.4 % of light, so the display beneath it stays bright and the colours true. Just as important as transmittance is haze, that is the proportion of scattered light that causes a milky tint; here it ranges only between 0.22 and 0.28 %. Such low haze means the image doesn't look matte and the glass is practically invisible on the display. As a result, the display protection is barely noticeable visually.

The fitting procedure is broken down into numbered steps: cleaning the display, placing the phone in the applicator, aligning the glass, and pressing it down. The bottom antistatic silicone layer doesn't attract dust and quickly draws air out from under the glass, so no bubbles or bright spots known as snowflakes form beneath it. The glass settles evenly and, once pressed, draws itself down onto the display. You can do the whole process yourself, without a service or special tools.
