5G Cutout Below Power Button?

[Recon0xe]

Watching new LTT video review of S24U and his device, like many I've seen in the US have an extra cutout below the Power button, what actually is it because mine doesn't have it in the UK, looks like a finger print sensor.

No it's for the 5G antenna.
The USA has a different version of 5G and needs a different design of antenna

It'll more than likely be for the mmWave (Millimeter Wave) antenna the European versions don't have mmWave antennas because we don't use mmWave

that is mm Wave 5G attenna, see following teardown video. It is identified there
