Then don’t take a phone. If you’re an organizer who needs to communicate, get a wifi/bt only tablet, look up mesh networks that use bluetooth and wifi, learn encryption and learn code words.
It’s trivial to jam any wireless network. All jamming is it to flood the rf range with loud static. But you can still take measures to keep from being spied on.
Edit: also look into if MAC address spoofing. Not entirely sure which models of phones support that, officially or otherwise though.
Honestly, there’s a wide range of quality of stuff produced in China, but the expensive stuff isn’t getting brought over. The better stuff is either being used domestically or exported to India/SEA. From my limited experience importing stuff, the biggest common factor is the lack of final quality control. I ordered some small diesel engines because no else makes those but Yanmar and Yanmar prices themselves way out of my range. Even Yanmar doesn’t sell a 5hp engine. The 196cc Chinese diesel was well designed, the parts well built, but final assembly lacks consistence on the bolt torque spec and there was metal shaving left in the crank case. The bigger, more expensive diesel made by a different company had much better quality control, although it’s still necessary to flush the crank case. No one over there seems to do that.
