- Works fine outside of calls
Likely causes

- PossibleSoftware freeze during the callA temporary app glitch can make on-screen and even physical controls unresponsive.
- PossibleCase interfering with the volume buttonsA tight or misaligned case can prevent buttons from being pressed fully.
- Less commonPhysical button hardware failureWorn-out button mechanisms can stop working over time.
What to do
- Try pressing the volume buttons firmly and check if they feel physically stuck or too stiff.
- Remove the case and test the volume buttons directly.
- Check if a connected Bluetooth or wired accessory is meant to control volume instead.
- End the call and restart the phone if the buttons seem unresponsive system-wide.
- Test the volume buttons outside of a call, like adjusting media volume, to see if the issue is call-specific.
- Clean around the volume buttons with a dry brush in case of trapped debris.
- Disconnect any accessory and test volume control using only the phone.
- If buttons remain unresponsive in all situations, they may need physical repair.
