Precautions for using waterproof mobile phones:
1. The safest water for waterproof mobile phones is fresh water below 30℃. Water with too high a temperature is easy to make the gasket age, thus losing its waterproof ability. Salt contained in seawater can easily rust metal parts, make buttons difficult to operate and even corrode circuits. Therefore, it is best to soak the mobile phone in fresh water for several hours after it is used in the seaside or seawater.
2. Most waterproof mobile phones have dustproof function, but large sand or soil may be fatal to mobile phones. Before replacing the battery or memory card and opening the sealing cover, please be sure to clean it with water. Otherwise, once the sand adheres to the sealed place, it is easy to cause the rubber pad to deform and leak.
3. The battery and the sealing cover at the interface can be said to be the weakest link of the waterproof mobile phone. Every time the mobile phone is flooded, carefully check the bayonet of the sealing cover and make sure it is closed. Be extra careful when opening it. If you have just soaked in water, dry the water on the fuselage with a soft cloth first to avoid infiltration.
4. If your waterproof mobile phone has no anti-seismic function, avoid bumping, because it is likely to cause the sealing interface to loosen at the moment of impact.
