TECNO Spark 20 Pro: Fix No Sound During Calls (Step-by-Step Guide)

Troubleshooting Call Audio Issues on TECNO Spark 20 Pro

• 💡 Check call volume by pressing the side buttons all the way up while on a test call, as the call volume slider may not appear otherwise.

• 🧼 Clean the earpiece gently with a soft brush to remove any dust or debris that might be obstructing the sound.

Alternative Calling Methods and Device Restart

• 📞 Try using different calling applications such as WhatsApp or other messaging apps instead of the default phone app to see if the issue is app-specific.
• 🔄 Restart your smartphone by holding the power button and selecting the restart option to resolve temporary software glitches.

Factory Reset and Data Backup

• ⚙️ If other methods fail, proceed to reset the phone by navigating to Settings > System > Reset phone.
• 💾 Back up your data to Google Drive before performing a factory reset to save important files, contacts, and apps.
• 🗑️ Initiate the erase all data process by confirming twice after entering your password to restore the phone to its default settings.
