iPhone 18 Pro Max audio popping/cracking with screen touches and haptics

Hi everyone and Apple Support,


I am experiencing a specific audio glitch on my brand-new iPhone 18 Pro Max running iOS 27. The issue is tied directly to screen touches, system haptics, and UI actions.


Detailed Symptoms Observed:


1. Screen Touch & Haptic Popping: Simply touching the display or triggering any haptic feedback causes a soft "popping" or "puffing" audio crackle through the top earpiece speaker.


2. App Icon & Folder Long-Press Trigger: Long-pressing any app icon or folder on the Home Screen (e.g., App Store, VLC, etc.) consistently generates a distinct popping sound right as the context menu opens.


3. Lock / Unlock Audio Pops: Locking and unlocking the phone produces a subtle crackling or popping sound alongside/instead of the clean system chime.


Technical Question & Community Guidance:

- In your opinion or experience, is this a pure software/DSP driver bug in iOS 27 linked to touch interrupts and the Taptic Engine, or could this be a physical hardware defect?

- I am still within my return window. Should I exchange/return the device for a full refund, or is this expected to be patched via an upcoming iOS software update?


Thank you for your feedback and guidance!

Expressing or conveying auditory experiences effectively through these forums may be challenging. The underlying sound issue on your iPhone cannot be accurately diagnosed from a YouTube link. Factors such as your iPhone's specific sound settings, visual defects, and potential hardware problems cannot be assessed through this method. For more personalized and in-depth assistance, I recommend securing a Genius Bar Reservation and exploring the various support options provided by Apple.

I bought a iPhone 18 pro on release day and took it home to set it up and experienced a static/raspy noise when my phone is on full volume on calls or when I play music. Called Apple and they did a remote diagnosis everything passed so they said it could be hardware issue. So returned the phone next day. Asked at apple if anyone else has had this issue they said no. So I bought a new one took it home, set it up and guess what.. had the exact same issue. So I also returned that phone. I've been reading around and now people are saying Apple is aware of the issue and it may be a software bug but it's almost been 3 weeks. So now I'm waiting for it to be confirmed to see if I should purchase the phone for a third time

I found that Voice Isolation feature is not working properly. I got crackling noise during a phone call. Also nobody hears me when I speak in car connected via Bluetooth. I switched Voice Isolation to “automatic” and now I don’t watch those problems. You can try switch to “standard” as well. This setting should be switched during a phone call. Please google it how to diy.

I hope Apple takes into consideration this issue and fix it in the coming days.
