Abstract: An electronic device having liquid-resistant modifications that prevent liquid ingress into an opening (or openings) in an enclosure of the electronic device is disclosed. For example, the electronic device may include a coating formed from a liquid-resistant material that is applied internally to the enclosure. The electronic device may further include a frame that carries a protective transparent layer designed to cover a display assembly. In order to secure the frame with the enclosure, the electronic device may include an adhesive assembly disposed over an outer perimeter of the coating. The adhesive assembly may include several adhesive parts initially separate from one another. However, with the adhesive parts between the frame and the enclosure, the adhesive parts can be compressed by the frame and the enclosure, causing the adhesive parts to expand and engage each other. As a result, the coating and the adhesive parts provide a seal against liquid.
