Why am I experiencing no sound on calls, unless on speaker?

I’ve been facing a frustrating issue with my phone where there’s no sound during calls unless it’s on speaker mode. When I place or receive a call, I can’t hear the other person unless I switch to the speaker. This problem is making it challenging for me to have private conversations, as I don’t always want to broadcast my calls publicly. I’ve checked the volume settings multiple times and ensured that everything is turned up. This issue seems to occur regardless of whether I’m using my earphones or not. It has become a consistent inconvenience, and I’m not sure what could be causing it. I haven’t dropped my phone or exposed it to moisture recently, so I’m puzzled as to why this issue has suddenly appeared.

A rogue app could be causing this problem. Some apps interfere with your phone’s audio settings. Here’s what you can do:
1. Boot your phone into Safe Mode, disabling all third-party apps temporarily.
2. Make a test call to see if sound works fine.
3. If it does, uninstall recently added apps one by one until you find the culprit.
This can be tedious but effective, and it’s worth trying before any drastic measures.

Contacting customer support can be very helpful. If your phone model is problematic, the support team might provide targeted solutions. Here’s what you do:
1. Provide all necessary details about the issue to the customer service representative.
2. Follow their instructions to troubleshoot the problem.
They can offer precise advice that’s model-specific and often more effective.

It’s possible the earpiece speaker is damaged. This can happen if dirt gets stuck in it or there’s something more serious internally. Here’s what you might try:
1. Clean the speaker gently using a small, dry brush or compressed air to remove any debris.
2. Call someone and gently tap near the speaker to check if sound cuts in and out.
3. If cleaning doesn’t work, visit a repair service to have the speaker inspected and potentially replaced.

Sometimes, the Do Not Disturb mode (DND) interferes with your calls. If enabled, it can silence calls unless on speaker mode. Here’s how to check and disable it:
1. Open the Settings app.
2. Find the Sound or Notifications section.
3. Look for Do Not Disturb and see if it’s turned on.
4. If it is, turn it off and make a test call.

Your network settings might have gone awry. Resetting these can sometimes resolve call sound issues. To do that, follow these steps:
1. Go to the Settings menu.
2. Access the general or system settings.
3. Look for an option to reset network settings.
4. After the reset, reconnect to Wi-Fi and make a call.
Resetting this can help spotty call issues by setting everything back to default conditions.

Bluetooth settings can sometimes cause this issue. If your phone is connected to a malfunctioning Bluetooth device, it might interfere with the sound. Try this:
1. Turn off Bluetooth via quick settings or the Settings menu.
2. Forget all paired Bluetooth devices.
3. Restart your phone and test a call.
If it works, reconnect your Bluetooth devices if needed. A reset of these connections can work wonders.

It may just be a matter of ensuring that your firmware is up-to-date. Phone manufacturers frequently release updates to address bugs or glitches:
1. Go to the settings menu.
2. Navigate to the ‘Software Update’ section.
3. If there’s an update available, download and install it.
4. Restart your phone and place a call to test.
Keeping your device updated ensures it’s running optimally.
