Water accidents are very common, either you are on a beach or a pool. Your phone can slip out of your pocket without your knowledge and when you would rescue it, it would have been too late. In these cases, waterproof smartphones are no less than a blessing.
Every phone has many gaps or holes from where water could possibly enter. For example; the buttons, every port, microphone hole or speaker grille. The main and the giant gap is between the rim and the glass screen of your smartphone. It is a little bit difficult to attach brittle glass screen directly to the frame without any gap and that is why they face a critical problem for the resistance of water.
To overcome this problem, manufacturers have started using quite a simple technique i.e. glue. A lot of glue which is commonly known as gaskets, adhesives, tapes or seals etc. but all of them have the same meaning. This rubbery and sticky glue is being used by the manufacturers now to make an airtight seal between the frame and the screen so it would reduce the possibility of water to enter your mobile phone.

Glue is not a great solution for everything because it sometimes oozes out of the removable parts, ports or buttons of the phone. O-rings are used in such cases when you want to prevent the glop from coming out of the phone. These are also known as rubber gaskets which are expanded because they are firmly pressed up against the surface from the inside.
Rubber rings are placed around all the ports, the headphone’s jack and some tiny rings around the SIM tray. However, for the buttons, silicone rubber is used in order to separate the electrical junction inside from the physical part outside. It is also used for the SIM card tray that you push to pop out. In iPhones, some cable connectors are also surrounded by these rubber rings to provide additional insurance.
Watertight Rather Than Airtight
Some of the parts are left unsealed such as microphones and speakers because air is needed to create vibrations to produce the sound. It is necessary to maintain a balance between the air pressure inside and outside the phone which can’t be possible with completely sealed and air tightened phone otherwise, airtightness would create a great opportunity for the pressure and water to breach through the mobile’s seal.
That is why manufacturers place a fine network in front of the speakers and microphones which wouldn’t let the water to pass through it. They also add waterproof fabric which lets the air to pass through it.
Use of Nickel
In some smartphones, nickel as a corrosion-resistant material is used to protect the charging ports which sometimes short out by switching them off automatically and which is why there is no need to port covers in modern waterproof smartphones.
Pay thanks to the latest technologies that come up with more innovative and helpful things and make your life a lot easier. On a side note, you can look into some great phone only plans if you want a waterproof phone.
