Lots of misinformation in this thread.
For one thing, no, the next Samsung phone, or any phone for that matter, does not have 5G.
5G's primary purpose is NOT to increase speeds, its primary purpose is densification – bringing better coverage to dense areas, areas where 4G coverage is overloaded.
Because of how short the 5g waves travel, and the fact that they don't pass through objects, it takes anywhere from 15-25 5G cells to cover the same area as a single 4G cell. Because of this, significant investment is required in order to stand up a 5G network. We likely won't see 5G widely rolled out for 10 or more years. And some towns just don't make sense at all for 5G. Dry, open cities like Phoenix are good candidates and will likely see it first. Humid areas dense with trees, like Atlanta, are very poor candidates. 5G even can be disrupted by rain. It just won't be as ubiquitous as 4G, likely ever. But it will have practical uses.
The standardization process for 5G isn't even complete. Right now companies are in the exploratory process, learning how to best use the technology and what it's applications will be, but no network has rolled out 5G for consumer use. Any network advertising 5G is lying to you.
At the moment, the technology required to receive 5G signal does not fit inside a device smaller than a router, much less a phone.
