Samsung snubbed the Snapdragon 810 for this year's flagship devices and used its own Exynos 7420 processor.

However a Korean report  suggests that Samsung is considering using the Snapdragon 820, internally known as Jungfrau, in the Galaxy S7 next year.

The company is apparently conducting intensive testing on the upcoming Qualcomm processor.The tests are going to provide Samsung with data that's going to make this decision easier.

The Qualcomm Snapdragon 820 will feature a 64-bit quad-core CPU with 14nm FinFET which promises 35 percent improvement over the Snapdragon 810, Adreno 530 GPU, LP-DDR4 RAM support, Cat. 10 LTE modem as well as support for 4K60 fps encode/decode, UFS and eMMC 5.1 storage solutions.

All this suggests that it is worth a look, rather than rejecting out of hand.  Besides the reason for the last batch of Snapdragons being rejected was the heating problem.  Qualcomm would be insane to let that happen again.
