Designed for Galaxy S21+ 5G

The OtterBox Commuter Series case fits the Samsung Galaxy S21+ 5G exclusively and will not fit the standard S21 or Ultra models. It adds a slim two-layer shell that slides easily into a pocket while covering every port with protective plugs.

Replaces basic snap-on shells

A single-layer plastic cover leaves ports exposed and cracks after one hard drop. The Commuter Series adds a rubber inner liner and a hard polycarbonate outer frame tested to survive four times the military drop standard, making the upgrade worthwhile for anyone who carries their phone on site or in a bag with tools.

Holds up to repeated impact

The dual-material construction absorbs shock across the inner liner before it reaches the outer shell, so protection remains consistent after multiple falls. Port covers keep dust and grit out of the charging and headphone openings, and the case stays fully compatible with wireless chargers so the phone never has to leave the case to recharge.

Questions about this item

Will the 6.61 in x 3.26 in x .54 in case fit my Galaxy S21+ 5G without blocking the camera or ports?

The case is moulded specifically for the Galaxy S21+ 5G, so the camera cutout, button covers and port openings line up exactly with that model.

How do I install the two-piece Commuter Series case, and what is the common mistake?

Snap the inner slipcover onto the phone first, then press the outer polycarbonate shell over it; the mistake is fitting the hard shell before the soft layer, which leaves gaps at the corners.

Do the built-in port covers on this case wear out and need replacing?

The integrated dust flaps are moulded into the outer shell and cannot be removed; if they tear the whole case must be replaced.
