After a 4G LTE model with 4 GB of RAM, a new Galaxy S7 variant shows up on Geekbecnh, but this time without LTE and with less memory.

I feel like this might be another samsung side project, like the Galaxy Alpha was. It makes very little sense to drop LTE.
Maybe just a variant for emerging markets where 4G will not become popular for at least three more years.
