Samsung Galaxy S22 Back Glass: when to replace it?

The back glass of the Galaxy S22 is the side most exposed to drops: an impact on the back of the phone can crack or shatter it without necessarily affecting the screen. Once cracked, it lets in dust and moisture, and the sharp shards make everyday handling unpleasant.

This part is only compatible with the Galaxy S22. It does not cover other models in the S22 range, nor neighbouring generations: check the exact model of your device before ordering.

A Service Pack part, not a refurbished part

This back glass is a genuine manufacturer part, supplied as a Service Pack. Nothing has been disassembled, repaired or reglued: it comes new from the official Samsung supply chain, in the packaging the manufacturer reserves for repairs. It's the box that sets it apart from a genuine part sold at retail, not any treatment the glass has undergone.

Its manufacturer reference, GH82-27434B, is the one Samsung assigns to this back glass: it allows you to check, before ordering, that this is indeed the part fitted at the factory on the Galaxy S22.

What fitting the back glass requires

The back glass is glued to the phone's frame using a heat-fusible adhesive. Removing it requires gradually heating the back of the device to soften the glue, then lifting it off without forcing the edges, where the glass breaks most easily during handling.

For a clean and lasting bond, a new adhesive strip is needed for each fitting: reusing the old glue rarely gives proper sealing. Fitting remains a technical operation, best left to a repairer used to disassembling the Galaxy S22.

What the warranty covers

This back glass is covered by a 2-year warranty. It applies to the part itself: a defect related to its manufacturing or conformity is covered over this period, independently of breakage occurring during subsequent handling.

Ordering the exact manufacturer reference, here GH82-27434B, remains the best guarantee of receiving the part that truly matches your Galaxy S22.
