Designed for Galaxy S21 Ultra 6.8

This Redpepper case fits the Samsung Galaxy S21 Ultra 5G 6.8 inch model released in 2021. It provides IP68 certified waterproof protection and full body coverage. The built-in screen protector and clear back defend against scratches and drops from 6.6 ft. Precise cutouts maintain access to all buttons and the fingerprint sensor.

Sustained underwater and impact protection

IP68 certification confirms the case survives submersion to 1.5 m for 30 minutes, suitable for swimming, snorkeling and underwater photography. The TPU and PC construction absorbs shocks from 2 m drops during extended outdoor activity. Multiple audio channels preserve call clarity throughout prolonged use without muffling.

Verify wireless charging and port alignment

Confirm your device is the exact 6.8 inch S21 Ultra 5G variant so cutouts match ports, buttons and the ultrasonic fingerprint reader. The case supports wireless charging without removal, but alignment depends on charger coil placement. Ensure no debris compromises the seal before water exposure.

Questions about this item

Does the IP68 seal trap heat while the S21 Ultra runs all day?

The TPU and PC shell dissipates normal phone heat; no active cooling is needed and the case adds no measurable thermal load.

Must I already own a wireless charger for the case to charge the S21 Ultra?

The case supports the S21 Ultra's built-in wireless charging coil; any Qi pad you already use will work through the cover.

Will the built-in screen protector interfere with the ultrasonic fingerprint reader on my S21 Ultra?

Precise cutouts and the integrated protector are designed to keep fingerprint unlock functional without removing the case.
