This is Qualcomm's first low-end SoC to support 5G, if that does anything for you, and there's even an option (though Nokia did not exercise it on the X20) for mmWave antennas.
The other big news of the day is that Nokia is extending support to three years now, with three years of major OS updates and three years of monthly security updates.Previously, the company was doing two years of major updates.
It seems like everyone—even lame-duck manufacturers like LG—is extending their Android support lately.
There is an excessive amount of rear cameras, with a 64 MP main camera, a 5 MP ultra-wide, a 2 MP depth camera, and a 2 MP macro camera.
There's no word on a US release yet, but HMD's Nokia phones with Qualcomm SoCs usually end up in the US eventually.
