Cracked glass on the back, over the Glyph. Replaced as a panel, so the lights and the wireless charging behave exactly as they did.

Nothing Phone (3a) Back Glass Replacement
A crack on the back does not stop the phone working, which is why it gets left — until the pieces start lifting, catching on a pocket, or letting moisture past the seal. We replace the panel rather than glue the cracks down, and check the Glyph lighting afterwards, because it sits directly behind the glass.
