The Samsung Galaxy S7 edge is being tested with Android 7.019
The version being tested with Android 7.0 is not a U.S. model, which we figured out by seeing that the Exynos 8890 chipset was found under the hood. The latter offers an octa-core CPU. Only models in the states and in China are powered by the Snapdragon 820 SoC, which features a quad-core CPU.
As we pointed out, the Galaxy S7 edge currently runs Android 6.0.1. Just because a Geekbench test shows Android 7.0 being tested on the handset doesn't mean that you should expect the update to arrive on your phone shortly. Those with an unlocked version of the device will get first shot at it, and U.S. carriers will be undergoing their usual testing to make sure that their networks play nicely with the new Android build.
