Bottom speaker not working after iOS 27 update

Nothing's impossible but it's not very likely the update caused a speaker to stop working. Again, if it did, this forum would be blown up with complaints.

After you updated your iPhone, did you Force Restart? I do this after every iOS update --> Force restart iPhone - Apple Support

Try that and see if it resolves. If it doesn't, you'll need to schedule an appointment at your Apple Store Genius Bar for evaluation and service options/costs --> Genius Bar Reservation and Apple Support Options - Apple

When will the next update be available, and will it fix these issues? The bottom speaker not working is really bothering me, and I hope this problem can be fixed soon.

As Jeff correctly suggests, there is only one speaker on the bottom of the phone and one at the top of the phone so you can hear callers. This can't be an update issue. If it was, this forum would be blown up with people complaining, but it's not.

I would open Settings > Accessibility > Audio & Visual > go down the page to Balance and make sure the slider is in the middle at 0.00.

It can be. The thermal stress of any heavy  software action including an update can trigger an already failing hardware component to fail completely. Fact. Nobody's fault.

The last straw breaks the camel's back. 

If after force restart it is no better have Apple look at it.

Are you sure the audio source has sound on both channels? That’s tricked me before listening to stereo and the recording on has sound on one channel.

if it was me and it played out of a connected headset then I would read

Which model iPhone? You’re aware that there is only one speaker on the bottom, correct? The other set of perforations are for microphone.

I’m using an iPhone 13 Pro. Yes, I understand that there is only one speaker on the bottom and the other perforations are for the microphone. The bottom speaker is not producing any sound after I updated to iOS 27.

It was working perfectly before I updated to iOS 27. The bottom speaker stopped working immediately after the update. I also reset all settings, but it still doesn't work. That's why I suspect it could be related to the software or the update.

I hope you all doing well. As updated my 12 pro max to 27 after some days suddenly today the iphone main bottom speaker is stopped working. I try to resolve it with settings of iPhone but none worked for me. Kindly look into this. Let tell you that kindly don’t reply with it like if this happens then this form will blows up. I will be thankful to whom ever responsible for solving such matter’s . Thank you😊.

Adding in a me too. Bottom speaker quit working after ios27 update; worked fine in 26, my phone is just a little over 1year old( iPhone 16e - got it in Aug/Sept 2025 - and I’ve read through every one’s suggestions, forced restart, balance is at 0.00, audio is stereo on, etc.).

it's not a general issue my iphone17pro plays just fine

so maybe it's not something with the software?

I have the same problem and the same phone. iPhone 13 Pro

This happened to me also. My 12 pro max’s bottom speaker stopped working after the update. Sound comes from only the call speaker

I’ve got the same issue! Have tried all of the software fixes but nothing has corrected it. So very frustrating!
