Samsung's flagship Galaxy S5 Android smartphone has been hit by reports that its camera can suffer from a bug that renders it unusable.
Users said that even resetting and wiping the device had no impact on the error, forcing them to return to a Samsung store to get it replaced.
"Returned mine yesterday for a replacement. Factory reset 3 times and even had the Samsung rep wipe it from scratch with Samsung image. No dice. Said it was a hardware failure," wrote one XDA user, Lilsalmon.
US network carrier Verizon also acknowledged it had seen the issue, telling customers to get in contact if they see the problem, in a message posted on Twitter.

Samsung acknowledged the issue in a widely reported statement.
"Samsung is committed to providing the best experience for customers. We have learned that a limited number of Galaxy S5 devices may have an issue that causes "Camera Failure" pop-up error message," it said.
It told users to call the relevant helpline or their mobile operator to have their device checked and serviced.
It is unclear how widespread the issue is with most users reporting the problem starting after around four or five days of normal use. Samsung will be hoping the problem is limited to a small number of devices as the Galaxy S5 is its flagship device in its ongoing battle for market dominance.
