Bloomberg reports that Samsung tested the Snapdragon 810, but the SoC overheated during testing and eventually the decision was made to drop it.

If true, Samsung’s decision will be a big blow for Qualcomm, which has powered several generations of Samsung flagship phones, namely Galaxy S and Galaxy Note devices with LTE. Samsung and Qualcomm did not wish to comment the matter.

Samsung is catching up with Qualcomm and other chipmakers in the SoC space. Its Exynos parts tend to be quite powerful, but lack of LTE support hampered deployment in many markets. It is unclear what sort of Exynos chip will be used in future Samsung smartphones, as the company has a good track record when it comes to keeping Exynos development secret.

Samsung is already using 20nm Exynos parts in some Alpha models, so it should have no trouble using the same chips, or beefed up versions, in Galaxy S and Note series products.
