Galaxy S25 Edge Switches From Glass Back To Lighter Material

During the unveiling of the Galaxy S25, Samsung also hinted at its forthcoming sleek smartphone. Believed to be under 6mm thick, the Galaxy S25 Edge is poised to become Samsung’s slimmest candy bar-style phone, potentially diverting attention from the rumored iPhone 17 Air. As the launch approaches, new insights reveal how the Galaxy S25 Edge could be lighter, linked to Samsung revisiting a previous design choice.

Reports indicate that the Galaxy S25 Edge will forgo a glass backing for enhanced durability. Instead, SamMobile provides exclusive insight into an alternative material. Sources suggest that Samsung plans to utilize a ceramic material in conjunction with an aluminum frame.

It’s not yet clear if the back will be fully ceramic or partially blended with glass. However, if accurate, the Galaxy S25 Edge’s rear should be both lighter and more durable than a standard glass back, even one fortified with advanced protective technology.

The Use of Ceramics in Smartphones

Although ceramic backs on smartphones aren’t entirely novel, they gained considerable interest among manufacturers in the late 2010s. Companies such as LG, Essential, HTC, and Xiaomi explored this material for their flagship devices. Even Samsung offered a black ceramic version of its Galaxy S10 Plus in 2019, noted for its superior durability compared to glass. Despite this, the use of ceramics did not gain widespread popularity due to the intricate manufacturing processes involved, which can drive up costs.

Ceramics encompass a class of materials that possess a crystalline structure—exhibiting a more symmetrical orientation at the molecular level. This characteristic lends them greater rigidity while maintaining a thinner and lighter form. Generally, any product made from clay and then fired in an oven qualifies as a ceramic, including porcelain which is commonly used in tableware.

The ceramics found in technology gadgets, like the Galaxy S10 Plus, are relatively sophisticated and demand extensive engineering. Prior implementations involved Zirconia (zirconium dioxide), a material also utilized in jewelry and dental implants, among other applications. It remains to be seen which direction Samsung will take with this new design.

With the inclusion of this unique material, Samsung might position the Galaxy S25 Edge as a more premium option compared to both the base and Plus models, possibly pricing it on par with the S25 Ultra. Performance and camera capabilities of the S25 Edge are anticipated to rival the Ultra, though the slim profile may raise concerns for users wanting to record lengthy videos or engage in gaming.

The phone is expected to be revealed in the second quarter of 2025, leaving just a few months until we confirm Samsung’s material choices.
