For the past few years, Samsung has released different SKUs of each flagship phone, including Snapdragon-powered models and options with a home-grown Exynos chip. But that may no longer be the case once the Galaxy S6 hits the market. Rumor has it the device could ditch Qualcomm entirely due to alleged issues with the company’s latest Snapdragon 810 processor.

Bloomberg reports that Samsung decided to skip the Snapdragon 810 after the chip began overheating during internal testing. This isn’t the first time we’ve heard murmurs that there could be an issue with Qualcomm’s latest processor, but until now we haven’t been sure what to think.

Two other smartphones are already set to launch with a Snapdragon 810 under the hood. LG’s G Flex 2 and Xiaomi’s Mi Note Pro were both announced earlier this month, though neither device is available to purchase yet. Still, we doubt either company would confirm plans to use Qualcomm’s chip if it failed in early testing.

Samsung’s alleged decision to shift away from its dependence on Qualcomm could also be part of a strategy to boost its own processor lineup. The company’s latest 64-bit Exynos 7 chip packs eight cores and it could be a big step up for the Galaxy S series.
