Problem phenomenon:
The customer’s voice is not clear or audible to the other person on the call, or the microphone is not working on the call.
Causes:
1. Signal Strength: Both the caller and receiver must have strong signal strength for a clear conversation. Weak signals on either side can lead to poor sound quality.
2. Device Issues: The other party's mobile device may have malfunctioned, resulting in low or absent sound.
3. App Compatibility: Some third-party phone applications may not be compatible with your phone model or software.
4. Microphone Hardware: Hardware issues with the microphone could hinder its proper function.
5. System Settings: Temporary corruption or misconfiguration in the system settings may occur.
Solution:
1. Improve Signal: Move to an area with better signal reception and try calling again.
2. Test Another Contact: Call a different number to check if the sound quality is normal.
3. Use Default App: Make calls using the default phone app pre-installed on your device.
