Samsung will not be building the next iteration of Qualcomm’s Snapdragon chipset into its next Galaxy S smartphone, according to Bloomberg. 

Instead the Korean OEM will build its own processor into the device.

The report cites unnamed sources who say that Qualcomm’s new Snapdragon 810 chip overheated during Samsung’s tests. Both Samsung and Qualcomm declined to comment in Bloomberg’s report.

As the report points out, Samsung is sinking $15 billion into a new factory in Seoul as part of its plan to be more self-reliant in the chipset department.

That push toward using its own processors coincides with the company’s move to integrate its homegrown Tizen operating system into its connected devices.

Tizen is finding its way into Samsung’s smart TVs and has a strong foothold in the company’s wearables, but the OS has had a tougher time working into the company’s smartphones and tablets. But last week Samsung unveiled its first Tizen phone, a low-cost device aimed at India’s emerging smartphone market.

Samsung has announced plans to push harder into the Internet of Things market but its flagship phones are still a huge part of the company’s business, even as smartphone sales flatten out for the company. Samsung earlier this month forecast its first drop in profit since 2011, with shrinking smartphone growth largely to blame.
