To clean your phone's microphone, try these methods:
1. Use compressed air (best method)
If you have a blower or a can of compressed air, direct the nozzle towards the microphone hole and blow some air to remove any dust or dirt.
2. Use a thin needle or fine wire
Take a thin needle or a fine copper wire (like the one in headphones) and gently move it inside the microphone hole to remove the dirt. Be careful not to damage the mic.
3. Use a soft toothbrush
Take a soft toothbrush and gently rub the microphone hole to remove the dust.
4. Use medical alcohol and cotton
Dampen a cotton swab with a little isopropyl alcohol and gently rub it on the microphone hole to clean it.
5. Try wiping the microphone gently
Sometimes, the dirt might be on the speaker. Try wiping the microphone with a clean cloth.
After cleaning, try recording a sound in the voice recorder and check if the problem is solved. If the sound is still weak, the issue might be with the microphone, and you may need to have it replaced by a technician.
