Galaxy Devices Freeze Up, But Can't Get Repairs Because Diagnostic Tools Show No Faults
Galaxy devices cannot be repaired even when they freeze up, as long as the diagnostic test says they are 'normal.' Cases are mounting of Galaxy smartphone, tablet, and watch users failing to get repairs because their actual malfunctions do not show up on Samsung Electronics Service Center's diagnostic program. Unless the problem is reproduced at the time of inspection, no action is taken even when consumers complain of inconvenience.
Consumer A, who bought a Galaxy Tab S11 Ultra online in June this year, experienced the tablet intermittently freezing, then shutting down with all buttons unresponsive. The symptom recurred two to three times a week with frequent use, and three to four times a month with occasional use. However, in mid-July, Samsung Electronics Service's Guri Center told A that repairs were impossible because the diagnostic program showed no problems. Afterward, at a Samsung Electronics Service Center in Suji, Yongin, Gyeonggi Province, the mainboard (the device's core circuit board) was replaced, resolving the shutdown issue—but A said the tablet then began rebooting on its own.
A pointed out that refusing repairs solely because the diagnostic program says 'normal' is problematic, and also raised doubts that the center's diagnostic tool seems little different from the Samsung Members online self-diagnosis.
Similar cases have continued on the online community Samsung Members. Galaxy Z Fold5 user B visited a service center after Wi-Fi and Bluetooth stopped working entirely, but the diagnosis came back 'normal,' and only later was told the mainboard had failed and that repair would be fully chargeable. Galaxy S25 Edge user C visited a service center twice for rapid battery drain and sudden power-offs, but was told repairs were impossible because diagnostics found no problem; after requesting a battery replacement, the symptoms disappeared. Galaxy Watch Ultra user D said the gesture feature for answering calls with a hand motion did not work, but was denied repair after an engineer's demonstration showed the function working normally—and it still did not work afterward. D argued that since the feature is needed for work, dismissing the issue as mere individual variation is hard to accept.
A Samsung Electronics Service official explained that the engineers' diagnostic program covers more items and more detailed content than the self-diagnosis tool. The official also said intermittent symptoms can be hard to verify if not reproduced, and that in such cases measures such as an aging test—leaving the device with the center to catch the symptom—can be taken. Yet when A first suggested an aging test, the center reportedly replied that no such service existed.
Lee Eun-hee, a professor of consumer studies at Inha University, pointed out that symptom data not captured by the diagnostic program should be collected to update the program, and that internal guidelines refusing repairs simply because nothing shows up are problematic. Prof. Lee said that since repair costs are already included in the product price, refusing repairs when the diagnostic tool detects nothing is a defensive service practice, and such internal principles could lead to a decline in consumer trust.
