If you're having trouble hearing audio from your iPhone's speaker, there are a few things you can try to fix the issue.
First, make sure that the volume on your phone is turned up and that the mute switch is not engaged. You should also check to see if the volume is turned up on the app or video that you're trying to play.
Next, you can try cleaning the speaker grill, as dust and debris can sometimes accumulate and block the speaker.
If the problem persists, it could be a hardware issue, in which case it may be best to take your phone to phonerepairaz.com for repair or replacement,
In the meantime, you can try using headphones or connecting your phone to a speaker to hear audio.
Remember, If you are not sure about any of these steps, it is always a good idea to contact the technical support of phonerepairaz.com support to help you troubleshoot the issue."
