The Android Nougat 7.0 in beta form for the Galaxy S7 and S7 edge, has gotten many users excited and with good reason as it comes with so many really cool features and the like. 

There's just one teensy problem for those who might want to manually flash one of the leaked ROMs.

Only Nougat's first beta build — build ZPK1 — has made its way out into the wild. That's the build with the light-blue (as opposed to white) quick settings, and a crashy Facebook app. None of the subsequent three builds — including the most recent ZPL3 — have leaked. So if you're flashing any of the leaked GS7 or GS7 edge builds via the ODIN utility, you're getting an older version.
If you don't see this as a problem, think again as in order to receive over-the-air beta updates, you need to be a member of Samsung's Galaxy Beta program. If you're not then you're going to stay on the first beta, which means manually updating to the final Nougat build once it's available, or flashing the latest Marshmallow firmware for your phone to downgrade.
The first beta still works relatively well — Facebook crashes notwithstanding — and gives you a decent preview of many of the features we're expecting to see in the final GS7 Nougat update.
