Tired of poor call quality on your Android? Quick tweaks like enabling Vo LTE (Voice over LTE) and Wi-Fi calling can deliver clearer, HD voice calls over 4G/5G or home Wi-Fi instead of older 2G/3G networks. On Pixel phones, go to Settings > Network & Internet > Mobile network > Vo LTE calls (or HD Calling); on Samsung, Settings > Connections > Mobile Networks > Vo LTE calls. For Wi-Fi calling, Pixel users navigate to Settings > Network & internet > SIMS > Carrier SIM > Wi-Fi Calling, while Samsung users go to Settings > Connections > Wi-Fi Calling.

Background noise reduction varies by manufacturer. Pixel 7 and later offer Clear Calling (Settings > Sound & vibration > Clear Calling), which filters noise and enhances voice. It also works mid-call via the volume panel. In VoIP apps like WhatsApp and Zoom, it requires Pixel 10 or later (excluding 10a). Newer Samsung Galaxy devices feature Mic mode — accessible during a call via Quick Settings — with Standard, Voice focus, and Full spectrum options. Mic mode works on both cellular and VoIP calls.

Remember: the other party's signal, mic, and environment also affect quality. Clean your microphone grille and ensure strong connectivity for best results.
