If your screen is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken glass.

Glass shards can complicate disassembly—or worse, cause injury. If your Steam Deck has a cracked screen, consider wearing safety glasses to protect your eyes from any glass shaken free during the repair.
