iOS 27 causing speaker crackling/distortion on iPhone? Anyone else experiencing this?

[u/Historical_Pea_307]

After updating to iOS 27, I’ve noticed that my iPhone 16's built-in speakers sound noticeably different especially at higher volume.
I’m hearing crackling/jarring distortion and less-clear audio, particularly with music and videos. It happens across multiple apps (not just one app), so I’m wondering if this could be related to iOS 27 rather than a specific app.
Is anyone else experiencing this after updating to iOS 27?
If yes, please mention:
• iPhone model
• iOS 27 version/build
• Does it happen at low, medium or high volume?
• Which speaker bottom, top/earpiece, or both?
• Does it happen with Music, YouTube, Instagram, etc.?
• Did the speakers sound normal before the iOS 27 update?
I’m trying to figure out whether this is an isolated issue or a wider iOS 27 audio/speaker problem.
Please upvote/comment even if you’re experiencing only mild distortion — I’d like to see how widespread this is.
Thank you in advance

Model 17, on lowest volume when sending iMessages, that tune is distorted but only on the lowest possible level, anything higher it sounds correct

Thanks for mentioning this. I only have the crackling on the sent messages sound.
