iPhone 18 Pro triggers wave of returns in South Korea after shutdown glitch
Within eleven days of hitting South Korean shelves, the iPhone 18 Pro ran into trouble. About 1,500 exchanges and 50 refunds were logged after a major flaw caused the phones to suddenly power off and restart. Both users and AppleCare called the problem 'panic full.'
These numbers are striking for a device that starts at 1.99 million won for the 256GB iPhone 18 Pro and 2.19 million won for the Pro Max. Early buyers, who paid top price expecting a smooth ride, instead found their phones freezing, shutting down, and rebooting out of nowhere. The glitch showed up right after the September 18 launch and quickly jammed up Apple's support lines. The company had to step in fast.
The 'panic full' shutdowns were not limited to simple reboots-many users reported their iPhone 18 Pro would freeze, display a black screen, and then restart, with these incidents logged as 'panic-full' events in the device's analytics data.
Software update fails to silence complaints
Apple rolled out 'iOS 27.0.1' on September 29, aiming to fix a bug that could cause surprise reboots if Face ID failed on the iPhone 18 Pro and Pro Max. According to The Korea Herald, this update was supposed to stop shutdowns linked to Face ID errors. Apple says the patch took care of the 'panic full' issue. But many users say the shutdowns keep happening. Some now report new problems, like apps closing on their own. Apple has told customers that any issues after the update fall under normal consumer dispute rules, and the company now treats these as separate from the original bug.
The scale of returns and refunds so soon after launch is rare for Apple in Korea. The company doesn't share model-by-model sales numbers, but this spike stands out in a market where new iPhones usually sell out and early buyers rarely ask for refunds. The return process depends on where the phone was bought. Apple store and online customers can return or exchange within 14 days for any reason. Carrier buyers need a service center to confirm a defect before they can get a refund.
Despite the release of iOS 27.0.1, independent confirmation of a broader official recall or exchange program by Apple or South Korean regulators has not been found. Reports indicate that even after the update, users continued to experience sudden shutdowns and system restarts, with new complaints about app crashes also emerging.
Consumer frustration and calls for transparency
South Korean lawmaker Kim Jang-kyom, who got hold of the Apple Korea data, has called on Apple to spell out exactly what caused the shutdowns and to give a full explanation to local customers. The lack of answers and the fact that problems lingered after the software patch have only made users more frustrated. For those who paid a premium, reliability is not up for debate.
This isn't the first time the iPhone 18 Pro Max has come under fire in Korea. As previous reports pointed out, buyers were already questioning the device's higher weight and price. Now, software trouble has added to their concerns.
How Apple handles the 'panic full' mess will shape its reputation in a market that values both new tech and accountability. When a flagship at this price point stumbles so publicly, the company can't just fall back on standard statements or vague promises. South Korean buyers have sent a clear message: they want a real fix and a straight answer about what went wrong. Anything less could chip away at the trust that keeps Apple's brand strong in one of Asia's toughest smartphone markets.
