How to Fix No Sound During Calls on POCO M7 Pro 5G

Troubleshooting Call Audio Issues on POCO M7 Pro 5G

• 💡 Check call volume during a test call and use the side volume buttons to adjust it.
• 🎧 Test if sound is audible through headphones or Bluetooth devices to determine if the issue is with the earpiece or the phone's overall audio system.

Checking Connectivity and Modes

• 🔌 Ensure Bluetooth is turned off to prevent audio from being routed to connected devices.
• 🗣️ Disable speakerphone mode during calls, as it might be defaulting incorrectly and causing no sound.

Earpiece and Software Checks

• 🧼 Gently clean the earpiece area near the front camera with a soft brush or microfiber cloth to remove dust or debris.
• 🚫 Disable Do Not Disturb (DND) mode, as it can silence calls and notifications.
• 💻 Update the phone's software to the latest version, as a software bug might be causing the audio problem.

Advanced Solutions and Hardware

• 💾 Before a factory reset, create a local backup or use Google backup to save your data.
• ⚙️ Perform a factory reset by going to Settings > About phone > Factory reset to restore the phone to its original settings.
• 🛠️ If the issue persists after a factory reset, it may indicate a hardware problem with the earpiece or audio chip, requiring a visit to an authorized service center.
