Black Rear Glass for Samsung Galaxy S21 Ultra 5G

The rear glass of the Samsung Galaxy S21 Ultra 5G in Black is a compatible part selected and inspected to offer an economical alternative to original manufacturer components. Unlike OEM parts, it comes from third-party manufacturers whose quality is validated before integration into the catalogue. Each batch undergoes strict quality control, performed in France or China depending on the product family, ensuring a low return rate and sufficient reliability for professional workshop repairs.

When to replace the rear glass

The rear glass of the Galaxy S21 Ultra 5G should be replaced as soon as you notice a crack, chip, or deep scratch on the glass coating of the device. An impact that breaks through the outer surface compromises the phone's water resistance and exposes internal components to moisture and dust. Damaged glass also affects the overall appearance of the device. Replacing this compatible Black part restores the appearance and protection of your Galaxy S21 Ultra 5G without intervention on the circuitry or sensor.

Cost savings without compromising quality

Choosing a compatible glass instead of an OEM part significantly reduces repair costs. Rigorous manufacturer selection ensures that this economical alternative meets the technical specifications of original parts while preserving stability and durability. This approach is suited for repair technicians optimizing intervention costs, intermediate repair offers, or device refurbishment in volume. Batch traceability and integrated quality monitoring ensure validated reliability across multiple test cycles.

Compatible with Samsung Galaxy S21 Ultra 5G only

This Black rear glass is designed exclusively for the Samsung Galaxy S21 Ultra 5G (model G998B). Before ordering, verify that your device matches this exact model. Glass installed on another Galaxy S21 or another generation would not fit correctly and would not provide the required fit or protection. Compatibility specific to this device is guaranteed by the quality control applied to each batch.

2-year warranty on this part

Each Black rear glass comes with a 2-year warranty covering manufacturing defects and technical compliance. This coverage reflects confidence in the quality validated in the workshop. If a problem is found during this period, the part will be replaced or credited according to the shop's policy. Damage caused by incorrect installation, a drop of the device after replacement, or physical impact are excluded from this warranty.

Package contents and installation

The package contains the Black rear glass ready to be installed. Installation requires careful removal of the damaged glass, complete cleaning of the chassis, application of adhesive compatible with the rear surfaces of the Galaxy S21 Ultra 5G, and positioning of the new glass. This operation is performed without disassembly of the battery or internal components. We recommend entrusting this task to a qualified technician to ensure water resistance and optimal fit, particularly on a high-end device like the Galaxy S21 Ultra 5G.
