On the Internet, you can see many life-saving tricks with smartphones. But be careful: not all of these tips work. You’ve probably heard that a wet or submerged smartphone must be placed on rice to get rid of water. But do these and other popular lifehacks really help?

It is even claimed that sometimes you can get rid of scratches on the screen in a similar way. But this is actually a myth.

A lamp from a smartphone. All it takes is a phone and a bottle of water. But still it is better to put the smartphone on the side of the bottle or use a flashlight. After all, this type of lighting consumes a lot of the phone’s battery.

fig. If you dropped the phone in water, the rice won’t help remove the moisture inside the device. Instead, it’s best to take the device in for repair right away.
