Learn about how to properly clean the receiver.
You may have this kind of experience: After a period of time, you may find that the volume of receiver is getting lower; sometimes it's mixed with noise which is hard to hear clearly. The following steps can help:
1. Clean the receiver
The issue above may occur if the receiver is blocked. During daily use, your phone's receiver might be contaminated by dirt and impurities. If any of the meshes look clogged, use a clean, small, dry, soft-bristled brush to clean them. Use the brush to carefully and gently brush all openings.
2. Set the volume on high
Go to [Settings] > [Sound & Vibration] to set the volume at maximum.
•For ColorOS 5.2 and above, go to [Settings] > [Sound & Vibration] > [Volumes] ,and then you can separately set the Ringer volume, Media Volume, and the Alarm volume to the maximum.
