The Galaxy Note 4 might not be selling as quickly as last year’s Galaxy Note 3 model, according to a new report out of Korea. News 1, a South Korea-based outlet, suggests it has learned that Samsung has sold 4.5 million Galaxy Note 4 units since the device’s official launch. The same report said that Samsung sold 5 million Galaxy Note 3 units during the same time period, suggesting that perhaps the Galaxy Note 4 is off to a slower start.

It’s important to note that these aren’t official figures from Samsung, so we don’t know the actual figure just yet. That said, the Galaxy Note 4 also only recently launched in the United States and Europe, in addition to other markets, after making its debut in South Korea, so it still hasn’t been as widely available during its first month on the market. Also keep in mind that Samsung fans may have upgraded to the Samsung Galaxy S5 earlier, instead of holding out for the Galaxy Note 4, so potential consumers may have already purchased a different Samsung handset.

Samsung’s strategy is obviously very different from some of its biggest rivals, such as Apple. It releases dozens of smartphones per year, instead of one or two models, as has been the case with Apple since the original iPhone’s debut. As such, Apple’s huge sales numbers during launch weekend, when it accepted orders for 10 million iPhones, are also a result of pent-up demand for its new smartphones.

Samsung typically releases some sort of sales figures for its flagship smartphone launches, but has remained relatively quiet on that front at least in terms of Galaxy S5 and Note 4 sales. We do know, however, that the Galaxy S5 beat out Galaxy S4 sales during launch weekend. We’ll be bringing you our full review of the Galaxy Note 4 soon and we’ll give you this spoiler: it’s an amazing device that’s far superior to last year’s model. If that’s any indication, Samsung’s sales should pick up as the phone is more widely available for purchase.

TechnoBuffalo reached out to Samsung for comment on official sales figures but a spokesperson was not immediately available for comment. We’ll update this story if we hear more.
