How to fix low or no sound during calls on your Samsung Galaxy device

Using a third-party screen protector or one that does not match your device's exact specifications can block the top receiver (earpiece).

• Check the top receiver (earpiece) of your device to see if it is covered by a screen protector or protective film.
• If the receiver is covered or partially blocked, remove the film or replace it with an official Samsung-approved screen protector that fits your specific model properly.

Galaxy models feature integrated air vents to balance internal and external pressure while maintaining water resistance. If these vents are blocked by a case or protective film, pressure changes can cause crackling noises or low sound from the speakers. This effect becomes significantly more noticeable when physical pressure is applied during seasons with extreme temperature changes, such as summer or winter, because the difference between internal and external pressure increases.

• Locate the air vent holes on the top or bottom of your device (e.g., Galaxy S26 Ultra features an air vent hole near the top edge and camera module).
• Inspect your phone case or any protective vinyl wraps to ensure they are not covering these holes. If a case or film is blocking the air vent, remove or adjust it to clear the air passage.
