How to fix low or no sound during calls on your Samsung Galaxy device
If you can’t hear the caller through the receiver or speaker on your Galaxy phone, try the steps below to resolve the issue.
Before trying the steps below, check the following:
- Make sure your device software and apps are up to date.
Step 1. Open Settings > Software update.
Step 2. Tap on Download and install.
Step 3. Follow the on-screen instructions.
Note: Device screenshots and menus may vary depending on the device model and software version.
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.
Make sure the in-call volume is set to the highest level.
When on a call, press the Volume up key to increase the in-call volume.
Note: You are only able to adjust the in-call volume when on a call.
The Mute all sounds setting turns off all audio on your device, including calls.
Step 1. Open Settings > Tap Accessibility.
Step 2. Tap Hearing enhancements.
Step 3. Make sure Mute all sounds is turned off. If not, tap the toggle to disable it.
Restart your device and then test it again.
Step 1. Swipe down from the top of your screen to open the Quick Settings panel.
Step 2. Tap the Power off icon.
Step 3. Select Restart.
