Proper isolation for each radio and other components is one of our hardware requirements:

It's one of the requirements that's available in all mainstream phones already, much more common than a lot of these.

Yes this is what I appreciate more and more since we spoke last time regarding pinephone I was so excited about. Unlike this little beast but it seems they have to improve their hardware a lot more in this regard.

Would you recommend any specific device on the market to measure the phone radio activity.

I would like to see what happens when it's in the "aeroplane mode" or WiFi turned off and SIM out.

I would like to believe the pixels shut down the activity of the radio modules but sources say most of phones of the market don't

The radio toggles do work correctly on Pixels and likely also work fine on other devices. Airplane mode is for disabling cellular and whether it disables Wi-Fi and Bluetooth too is a user choice. Disabling SIM is a different thing.

#Googel is a mobile phone provider and could theoretically have installed #M2M profiles in the #eSIM on its #Pixel. Or update them over-the-air at a later date. I think what was meant was that with proprietary hardware in flight mode, you would only have certainty when the radio emissions are measured.

Of course, you still don't know if there is any unwanted data leakage past the #GrapheneOS operating system. This is one of the main problems with proprietary hardware. To find out, you would have to be able to read the encrypted 5G radio traffic.
