There are a few things you can try first:
* ***Restart your phone.*** This is often the simplest way to fix minor problems.
* ***Check your volume settings.*** Make sure that your phone's volume is turned up and that you're not in silent mode.
* ***Clean the speaker grills.*** The speaker grills on your phone can get clogged with dirt and dust, which can block the sound. Use a soft brush or cloth to gently clean the speaker grills.
* ***Update your phone's software.***Sometimes, software updates can fix bugs that cause problems with the speakers.
