With the development of modern smartphones, the functions of mobile phones are increasing, and the requirements for the overall sealing of the phone structure are also becoming higher. Nowadays, the mainstream effective waterproof technology for mobile phones actually adopts the method of preventing water from entering the inside of the phone.
The waterproof smartphones on the market have a waterproof plug at the bottom data interface, and a sealed rubber ring is attached to the back cover to protect the back and prevent water from entering the battery area. At the same time, to prevent prolonged immersion in water without being affected, the phone screen is firmly attached, with a closed metal frame designed around it. A layer of waterproof glue is glued around the HOME button to prevent water from entering when pressing the button in water.
