PinePhone Postmarket OS UK users

[LinuxNew]

Hi all hope everyone is doing ok?

So I have a few questions about the PinePhone Postmarket OS.

Does anyone here own or have used the PinePhone Postmarket OS in the UK?

And if so hows that going?

Also the hardware kill switchs?

Do they work the same as the Librem 5 kill switchs that directly cut power to the circuit?

Or are some of the HKS on the PinePhone software based, meaning they ask the software
to stop working rather that physically cut a circuit?

Thanks in advance
