OPPO A5x: Fix No Sound During Calls with These Simple Steps

Troubleshooting Call Audio Issues on OPPO A5x

• 💡 Check call volume during an active call using the side buttons, as the dedicated call volume setting is only accessible when on a call.
• ⚠️ Ensure Bluetooth is disabled to prevent audio from being routed to an external device instead of the phone's earpiece.

Physical Checks and App Testing

• 🧼 Gently clean the earpiece with a soft brush to remove any debris that might be obstructing sound.
• 📱 Test calls in different applications, not just the default phone app, to determine if the issue is app-specific or system-wide.

System Refresh and Reset Options

• 🔄 Restart your OPPO A5x by holding the power and volume up buttons simultaneously to refresh the system.
• ⚙️ As a last resort, perform a factory reset after backing up your data to restore the phone to its original settings. Navigate to Settings > System and Updates > Backup and Reset > Reset Phone > Erase All Data.
