iPhone 18 Pro speaker crackling is being reported by owners of both Pro models, coming from the earpiece at the top of the screen. Complaints surfaced about 12 days after the phones went on sale on 18 September 2026, and iOS 27.0.1 did not stop them. Apple has made no public statement.

What Owners Are Hearing, and When

The noise is described as a crackle, a faint tick or pop, or random clicking, and it comes from the earpiece speaker at the top of the screen rather than the louder bottom speaker used for media.

It is not constant for everyone. Some owners hear it continuously; others only in specific moments. The triggers reported across the MacRumors forums, Reddit and Apple’s own discussion boards are unusually consistent:

  • Switching between apps, or scrolling a web page
  • A notification arriving
  • The on-screen keyboard appearing
  • Making or taking a call over a cellular connection
  • Turning Airplane Mode on and then off, which several owners say reproduces the sound on demand
  • Changing screen brightness quickly
  • Adjusting the volume, or playing audio loudly

That pattern — noise tied to the screen, the radio and the volume control rather than to audio playback alone — is why most coverage treats this as a software fault rather than a bad batch of speakers. Nobody has demonstrated the cause.

Affected Models and Launch Regions

Only the two 2026 Pro models appear in the reports: the iPhone 18 Pro and the iPhone 18 Pro Max, running iOS 27.

Both went on sale on Friday 18 September 2026 in an initial group of countries including the United States, the United Kingdom, Germany, France, Japan, India, Canada, Australia and China, reaching 20 further countries on 25 September. As of 1 October 2026 there is no report of a matching fault on the standard iPhone 18, the iPhone Air or earlier models, and no figure for how many handsets are involved — the reports are self-selected forum and social posts, not a count.

Some owners who exchanged a phone at an Apple Store received a replacement that made the same sound, which is the strongest available argument against a manufacturing defect.

What iOS 27.0.1 Did and Did Not Fix

Apple released iOS 27.0.1 on 28 September 2026, and the speaker is not on its list. The release notes name three fixes:

  • Face ID restarts: iPhone 18 Pro and iPhone 18 Pro Max could restart unexpectedly when Face ID failed to authenticate, the problem covered in our earlier report on the iPhone 18 Pro Face ID bug.
  • Camera colour artefact: a colour artefact could appear on photos taken at 2x in certain lighting at f/1.48 on a small number of iPhone 18 Pro and Pro Max units.
  • Unresponsive touchscreen: opening Notification Center and Control Center at the same time could leave the display unresponsive.

Apple’s security listing records no CVE entries for the update, so nothing else was quietly patched under a security heading. Most owners who installed it say the crackling continued unchanged; a minority whose noise only occurred during calls report it stopped. This is the second complaint about iOS 27 that Apple has neither fixed nor acknowledged, after the battery drain reports earlier in September.

What Reduces the Noise Right Now

One setting change has produced a reported improvement; everything else is inconclusive. Try them in this order.

  1. Step 1: Open Settings, then Apps, then Phone, and set the call audio option to Standard instead of Voice Isolation. One owner told Macworld this produced “way less crackling”.
  2. Step 2: Install iOS 27.0.1 if you have not already, since it resolved the noise for some owners whose problem was limited to calls.
  3. Step 3: Power the phone fully off and back on rather than restarting it. Results here are inconsistent, and several owners report the sound returning within hours.
  4. Step 4: Record the sound on a second device before contacting Apple. The noise is intermittent and quiet, and a recording is the difference between a diagnosis and a dismissal.

Voice Isolation is the iOS feature that filters background noise out of your voice during calls using on-device processing. Turning it off changes how calls sound to the person you are speaking to, so this is a trade, not a cure.

Return Window and Warranty: The Dates That Matter

Apple’s standard return period is 14 calendar days from purchase or delivery, which for launch-week buyers is closing now.

18 September 2026, launch day2 October 2026
25 September 2026, second wave of countries9 October 2026

Those dates apply to purchases direct from Apple; carriers and other retailers set their own terms, and some countries add statutory rights on top. After the return window, the route is the warranty. Apple warrants the iPhone “against defects in materials and workmanship when used normally in accordance with Apple’s published guidelines for a period of ONE (1) YEAR from the date of original retail purchase”, according to Apple’s one-year limited warranty for iOS devices, and it may repair, replace or refund at its option.

The practical catch is that a warranty replacement has already failed for some owners, because a software fault travels to the new handset. A refund inside the return window is the only remedy that does not depend on Apple shipping a software fix.

What Apple Has Not Said

Apple has not acknowledged the problem, published a support document, opened a service programme or said whether a fix is coming in a future iOS 27 release. It has not said whether the cause is software or hardware. Store staff have reportedly offered exchanges case by case rather than under any announced policy, and Apple has not confirmed that either.

Frequently Asked Questions

Hardware Fault or Software Bug?

It has not been established. Owners who received replacement handsets report the same noise, which points to software, but Apple has published no diagnosis.

Did iOS 27.0.1 Fix the Crackling?

Not for most people. The 28 September 2026 update lists fixes for Face ID restarts, a camera colour artefact and an unresponsive touchscreen, and does not mention the speaker.

Which Models Are Affected?

Reports name the iPhone 18 Pro and iPhone 18 Pro Max only. No matching complaints have surfaced for the standard iPhone 18, the iPhone Air or older iPhones.

Does Turning Off Voice Isolation Stop It?

It reduced the noise for at least one owner who spoke to Macworld, but it is a reported workaround rather than a confirmed fix, and it changes how your voice sounds on calls.

Can I Still Return the Phone?

Apple’s return period is 14 calendar days from purchase or delivery, so launch-day buyers reach the end of it around 2 October 2026. Other retailers and national consumer law may give you longer.
