Common Causes of Poor Call Quality

Before fixing the issue, it is important to understand the possible causes.

One of the main reasons is weak network signal. If you are in an area with poor coverage, call quality will automatically decrease.

Another reason could be network congestion. During busy hours, networks may become overloaded.

Phone-related issues such as faulty microphones, speakers, or incorrect settings can also affect call clarity.

Sometimes, background apps or software bugs may interfere with call performance.

Identifying the cause helps you apply the right solution.

Check Network Signal Strength

The first thing to check is your network signal.

If your signal bars are low, try moving to a different location where the signal is stronger.

Open areas usually have better reception compared to closed or underground spaces.

Improving signal strength can instantly improve call quality.

Restart Your Phone

Restarting your phone is a simple but effective step.

It refreshes system processes and removes temporary bugs that may affect call performance.

After restarting, try making a call and check if the quality improves.

Clean Speaker and Microphone

Dust and dirt can block the speaker and microphone, affecting sound quality.

Use a soft brush or cloth to clean these areas gently.

Avoid using water or sharp objects.

A clean speaker and microphone can make a noticeable difference in call clarity.

Remove Phone Case (If Needed)

Some phone cases can block the microphone or speaker.

If you are facing call issues, try removing the case and check if the quality improves.

Using a well-designed case ensures better sound flow.

Check Network Mode

Incorrect network mode settings can affect call performance.

Go to network settings and select the appropriate network type, such as 4G or LTE.

Switching network modes can sometimes improve call quality.

Disable WiFi Calling (If Problematic)

WiFi calling can sometimes cause call issues if the internet connection is weak.

Try disabling WiFi calling and switch to mobile network calls.

This can help improve stability and clarity.

Update Your Phone Software

Software updates include bug fixes and performance improvements.

Outdated software may cause call-related issues.

Check for updates regularly and install them when available.

Keeping your phone updated ensures better performance.

Reset Network Settings

If call issues persist, resetting network settings can help.

This restores default configurations and removes incorrect settings.

After resetting, reconnect to your network and test call quality.

Check SIM Card Condition

A damaged or old SIM card can affect call quality.

Remove the SIM card and check for any visible damage.

If needed, replace it with a new SIM from your network provider.

Avoid Network Congestion

Call quality may drop during peak hours when many users are connected to the same network.

If possible, try making calls during less busy times.

This can improve connection stability.

Turn On VoLTE (If Available)

VoLTE (Voice over LTE) improves call quality by using high-speed network technology.

It provides clearer voice and faster call connection.

You can enable VoLTE from your network settings if your phone and SIM support it.

Using VoLTE can significantly enhance call clarity.

Close Background Apps

Apps running in the background can interfere with call performance.

Close unnecessary apps before making calls.

This frees up system resources and ensures smoother operation.

Too many apps running in the background can affect call clarity. You can manage them by reading How to Stop Apps from Auto Starting on Android (Complete Guide 2026).

When to Seek Professional Help

If none of the methods work, there may be a hardware issue.

Problems with the microphone, speaker, or internal components can affect call quality.

In such cases, it is best to visit a professional technician.

Tips to Maintain Good Call Quality

To maintain good call quality, always keep your phone clean and updated.

Avoid using damaged accessories.

Stay in areas with good network coverage.

Restart your phone occasionally to keep it running smoothly.

These habits can help ensure consistent performance.

Note:

Call quality is an important part of smartphone usage, and poor performance can be frustrating.

By checking signal strength, enabling VoLTE, cleaning your device, and updating software, you can improve call clarity significantly.

In most cases, these simple steps are enough to fix call issues.

With proper care and settings, you can enjoy clear and smooth calls every time.
