Have you ever w 76 the cartoon film The Black Cat Detective It was on show in 2010. The story is about the detective Mr Black Cat travelling around on his motorcycle and solving p 77 of cases (调查的案件) in the forest. He is clever and brave.

So what should you do instead If the phone is dropped in water, dry it with a towel or clean cloth, and even a shirt will do. Turn the phone off if you can. Remove its SIM card. Remove the phone’s cover. Remove the battery, if possible. And let everything dry at room temperature, perhaps with a fan running. Since you cannot take the phone apart, Apple suggests tapping the phone against your hand with the connecting ports (端口) facing down so water can flow out.
If your phone is dropped in seawater, treated water, or a drink, Samsung suggests keeping it in clean water for a few minutes. Doing that will remove any salt or substances that could hurt the phone. Both Apple and Samsung say it’s best to leave the phone out in an open area to dry it out. More importantly, do not use a hair dryer or put the phone in a freezer.
Most newer phones are not waterproof (防水的) but they are water-resistant. Apple says its newest phones can survive 30 minutes in up to 6 meters of water. Samsung’s phones can last for the same amount of time in about 5 meters. But remember that the water resistance will decrease over time.
The phone manufacturers say it is hard to know when phones are completely dry. But it will likely take a few days. Samsung advises bringing the phone into a service center for inspection even after it’ s been air-dried.
56．Why can’t we put a wet phone in the rice
57．What does Apple tell us to do to rescue a wet phone since we cannot take the phone apart
58．What does Samsung suggest doing if a phone is dropped in seawater
