How to Boost Call Clarity on Your Android Device

Frustrated by constant requests to repeat yourself during phone conversations? There are several straightforward adjustments and hidden settings on Android that can significantly enhance call audio quality. While basic maintenance like cleaning the microphone is always recommended, leveraging built-in technologies such as VoLTE, Wi-Fi calling, and specific sound customization tools can make a substantial difference.

It is important to note that Android interfaces vary by manufacturer, so menu locations may differ. Furthermore, call quality is a two-way street; poor reception, bad microphones, or noisy environments on the recipient’s end will impact the experience regardless of your phone’s settings. However, there are several elements under your control.

One of the most effective ways to improve voice clarity is by enabling VoLTE (Voice over LTE). This technology routes calls through high-speed 4G data networks, offering clearer sound, HD voice capabilities, and faster connection times compared to older 2G or 3G networks. On most Android devices, you can activate this by navigating to Settings, selecting Network & Internet, then Mobile network, and toggling on VoLTE calls. Samsung users may find this option labeled as HD Calling or 4G Calling within Connections > Mobile Networks. For devices supporting 5G, similar improvements are available via Voice over New Radio (VoNR).

Wi-Fi calling is another powerful tool for improving audio quality, particularly in areas with weak cellular signals. This feature converts your voice into digital data packets and transmits them over Wi-Fi networks rather than cellular towers, reducing congestion and signal obstruction. To enable Wi-Fi calling, go to Settings, select Network & internet, choose SIMs, and then tap on Carrier SIM to access Wi-Fi Calling options. Samsung users should look for the Wi-Fi Calling toggle under Connections.

Background noise reduction is also critical for clear conversations. Google Pixel smartphones feature a tool called Clear Calling, which filters out ambient noise and enhances voice quality. It can be activated in Settings under Sound & vibration, or toggled during a call via the volume panel. Please note that Clear Calling is available on Pixel 7 devices and newer, while its integration with VoIP apps like WhatsApp and Zoom is limited to Pixel 10 models and later, excluding the Pixel 10a.

Samsung offers a comparable feature known as Mic mode, accessible during active calls through the Quick settings panel. Users can choose between Standard, Voice focus, or Full spectrum audio processing depending on their environment. This feature is available on select newer Galaxy devices and works across both regular calls and VoIP applications, though menu options may vary by app.

For those struggling to hear the other party, audio customization features can help. Samsung’s Adapt Sound tailors audio output to compensate for specific hearing deficiencies, either through age-based presets or a customized hearing test. This feature is effective when using headphones. Pixel devices offer Adaptive Sound, which uses the phone’s microphone to automatically adjust speaker frequencies based on environmental noise, boosting mid and high frequencies in loud settings. Other Android manufacturers may have their own versions of these features, so exploring the Settings app is advisable.

If these software adjustments do not resolve the issue, physical obstructions such as dust, lint, or certain phone cases may be blocking the microphone or speaker. Checking for and removing any blockages can often restore optimal call quality.
