Apple iPhone 18 Pro launch hasn’t been smooth. Users keep discovering new bugs, and the latest one concerns an audio glitch in the earpiece. Some report the issue appeared after their iPhones were updated to iOS 27.0.1. This is everything you need to know.

iPhone 18 Pro owners all over Reddit describe the glitch as a popping or crackling sound from the earpiece speaker. And it happens every once in a while when they interact with the software. No pattern has been caught, though a few specific actions trigger this popping noise.
The Pro and Pro Max suffer from the same issue, by the way. At least that’s what we gather from the reports. App use and normal web browsing could randomly cause a pop sound. Even notifications and typing have the same effect.

People go as far as to blame Airplane mode and the brightness slider for the bug. There’s also a faint buzz in the speaker when the volume is set to full. iPhones had another bug at launch where a failed Face ID check would cause the device to crash and restart.

They did fix the issue with the new iOS 27.0.1 update, but it simultaneously created another bug on the Apple new iPhone model and Pro Max. There hasn’t been any sign that this is a hardware issue, so maybe an update could fix the audio bug on the latest models.
Apple hasn’t really acknowledged this new issue, and there hasn’t been any new update. They are probably in the dark, just as they were with the widget bug. When you drag a widget on the iPhone 18 Pro from one home screen to another and stack it on another widget, it causes the system to glitch, which only a hard reset fixes.
First, the Face ID bug, and then the widget crash. Now there are reports of an annoying sound bug, all in the same month of release. This is the most bug-ridden iPhone series we’ve ever seen. This could tank Apple’s reputation as the most stable product maker. We’ll let you know when they deploy a fix for the audio issue. Keep watching the news.
