Confirm where audio is playing

Disconnect Bluetooth and casting devices, then verify that the phone speaker is the selected output.

Step 2

Compare calls and media

A quiet earpiece during calls but normal media volume points to a different speaker path than quiet sound everywhere.

Step 3

Inspect the grille and consider moisture

Remove the case and look for visible blockage without inserting objects. If recent water near the grille is likely and the phone is stable, consider one moderate rescue cycle and allow drying time.

Step 4

Know the limit of boosting

Software gain can make a file louder but cannot restore a damaged speaker or exceed the phone’s hardware maximum cleanly.

The short answer

Software gain can make a file louder but cannot restore a damaged speaker or exceed the phone’s hardware maximum cleanly.
