With the help of some common items in life, you can maximize the functionality of the phone itself.
1.Smartphones usually come with a flashlight, and with the help of a bottle filled with water, you can turn this light source focused in one direction into a lamp.
First of all, lay the phone with the flashlight function turned on flat to ensure that the light is upward, and then put the water bottle with the wrapper peeled off on the phone and let it cover the light. The water in the bottle allows the light to scatter in different directions, illuminating a larger area.
2.If the volume of your phone's speakers is turned up to maximum and the sound is still too low, you can put your phone in a bowl or glass. This will make the sound quality worse, but it will make you hear louder because the sound is reflected off the wall of the bowl or cup and is gathered together, and the sound waves that would have traveled in other directions also enter your ears.
3.To improve audio quality and block out background noise while on a call or **recording, cover the microphone with a tissue or something else. This protects the microphone membrane from the airflow, which can cause a popping sound and reduces the volume of noise. When recording at a concert**, cover the microphone to reduce background noise and audience screams, highlighting the singer's voice.
