Samsung told Reuters it had delayed shipments of the flagship Galaxy Note 7 while it carries out additional quality control tests on the device.
The vendor did not provide detail on what is being tested, how long the delay was likely to last and which markets will suffer delays.
South Korean media reported that some users claimed the battery in the Galaxy Note 7 had exploded. The device was launched earlier this month with a lot of hoopla, as befits a device for which Samsung has high hopes.
This latest news follows a report a week ago that Samsung was seeing supply constraints for the Galaxy Note 7, following strong initial sales for the flagship smartphone.
The company admitted in a statement last week that pre-orders had “far exceeded our estimates”, leading to its release schedule for some markets being “adjusted”.
While strong demand for a new product is clearly good news, the ability to capitalise on this by supplying products is an equally important part of the equation.
This is particularly true with the anticipated launch of Apple’s iPhone 7 next month, as well as new devices unveiled at IFA2016 this week by vendors such as Huawei.
