When you carry a flagship smartphone like the iPhone 17 Pro Max, its radiant glass rear is as much a statement piece as its display. That glass, however, is vulnerable: the slightest scrape or impact can mar the finish or crack the surface. While front screen protectors have long been standard, protecting the back glass is equally important—especially for users who value aesthetics, resale value, and structural integrity. In this post, we delve into three back glass (or back surface) protectors—Shacorye, Suttkue, and Junjiacolor—and consider what makes a top-tier protector for your iPhone 17 Pro Max.
1. Shacoryze Back Screen Protector
The Shacoryze back protector is known as a tempered glass rear shield for earlier iPhone models. Though mostly marketed for earlier generations, the same design philosophy applies to what one would expect for the 17 Pro Max. Specifically crafted for the iPhone 17 Pro Max, this back glass protector features a 2.5D curved edge. Due to the matte finish of the phone’s back, the protector adheres only along the edges, keeping the central area clear and free from fogging while preserving all device functions.
Its streamlined, non-edge-to-edge design ensures a secure grip, preventing the protector from peeling, and improves compatibility with most cases by minimizing edge pressure and reducing the risk of cracking. On installation, you should align the lens area precisely to avoid interfering with cameras or sensors. The tempered design also tends to resist bending—but that same rigidity makes precise alignment more critical, and any trapped debris is harder to correct once stuck.
2. Suttkue Back Screen Protector
The Suttkue name is less prominently found in mainstream smartphone accessory listings, but in the screen protector niche it suggests designs focused on tempered or hybrid glass panels. A Suttkue back glass protector would aim to offer fine transparency, edge bonding, and scratch resilience. This back screen protector offers 99% high-definition clarity and 99% light transmittance, preserving the bright, vivid colors and sharpness of your iPhone 17 Pro Max display. Its high transparency and responsive surface follow a 2.5D curved edge design for a smooth, natural feel.
Made from 9H hardness tempered glass, it is significantly stronger than standard film, providing reliable protection against scratches, impacts, and breaks.
The protector is designed for easy, hassle-free installation—dust-free, fingerprint-resistant, and bubble-free—allowing even inexperienced users to apply it effortlessly with just one touch.
3. Junjiacolor Back Screen Protector
Junjiacolor is primarily known in accessory marketplaces for back or rear glass shields for various devices. For the iPhone 17 Pro Max, a Junjiacolor back glass protector would ideally combine tempered glass durability with slim thickness and high visual clarity. Its strength would lie in preserving the iPhone’s design while adding a sacrificial layer. Because Junjiacolor also sometimes offers colored or tinted variations, one must select a totally transparent variant for a device like the iPhone 17 Pro Max to preserve the original aesthetics. Given typical usage, a Junjiacolor protector should also include a polished edge and oleophobic coating to resist fingerprintsThe back cover hydrogel film for the iPhone 17 Pro Max features self-healing technology, allowing minor scratches to gradually disappear and keeping the film clear and intact over time.
It provides essential protection for your phone’s rear, helping maintain its like-new appearance and guarding against everyday scratches.
