A226 A22 5G Adhesive sticker

Samsung GH81-20750A adhesive sticker is a replacement adhesive part for the battery cover area of the Galaxy A22 5G A226B. It sits under the cover and is intended for re-gluing components after the phone has been dismantled.

The listing identifies this part as an Original Service Pack spare part. Replacing the adhesive can help restore the cover bond during a repair. The source notes that it may also help restore water resistance after dismantling, depending on the device; that outcome is not guaranteed by the adhesive alone.
