Black rear glass for Galaxy S25 Plus: when to replace it

The rear glass of the Galaxy S25 Plus protects the camera sensors and contributes to the device's water resistance. It cracks or scratches from daily impacts, and each impact compromises chassis rigidity. A damaged rear screen is often accompanied by vibrations when taking photos, loss of water resistance or simply degraded aesthetics. This compatible black glass restores the original structure and returns the phone to normal operation.

A network crack, even fine, spreads under pressure: each handling worsens the damage. Loss of material at the corners exposes water resistance seals. A haze or deep scratches affect appearance and trap dust. All these symptoms signal that it is time to replace the glass.

Compatible part: selection and workshop testing

This rear glass is a compatible part manufactured by third parties, selected and tested to meet Galaxy S25 Plus specifications. Unlike an original manufacturer part, it offers an economical alternative without sacrificing reliability. Each batch undergoes systematic quality control: fit verification, water resistance testing, material compliance. This process guarantees a controlled return rate and recognized usage stability in the workshop.

This approach is aimed at repair technicians and individuals seeking a balance between repair cost and lasting performance. The black glass fits into economical repair offers, refurbished second-hand units or fleet maintenance. Its reduced price does not mean a loss of durability: it offers the same resistance to shocks and temperature variations as more expensive alternatives.

Compatible only with Galaxy S25 Plus

This glass is designed for the Galaxy S25 Plus only, manufacturer reference S936B. Not suitable for Galaxy S25 Ultra or other Samsung generations: each model has its own proportions, sensor cutouts and thickness. Before ordering, verify the S936B code on the broken device, usually engraved under the battery or in the Settings app (About phone section).

What you receive and how to proceed

The package contains the black rear glass, without adhesive or tools. Installation requires a heat gun to soften the original adhesive, a fine spatula to remove it without scratching the chassis, and new glass adhesive (to be ordered separately if you do not have it). The installation takes approximately 30 minutes for a trained technician, 45 minutes for an amateur: controlled heating, patient removal of the old seal, cleaning of all residue, application of new adhesive in a thin peripheral bead, uniform pressing during drying.

No adhesive in the package
No tools or instructions

Essential precautions: never remove cold, you risk fracturing the chassis or the sensor welding areas. Heat gradually, without exceeding 80 °C. Remove every trace of old adhesive: residue creates an air bubble that worsens over weeks. Allow new adhesive to dry for at least four hours before use.

2-year warranty on this part

This rear glass is covered by a 2-year warranty from the date of delivery. It covers manufacturing defects, spontaneous cracks without apparent impact and fit problems with the chassis. Damage related to poor installation, subsequent impact or exposure to extreme temperatures is not covered by this warranty. If you have any concerns, contact the store with a photo of the part and a description of the problem: a quick diagnosis allows for an exchange or refund.
