The solution will be to have a slider that physically disconnects the networks. Slide it down and the hardware is no longer physically connected. The phone still have all it's no-connection features. Slide it up and you are back online.
We cannot trust software to actually disconnect as advertised. It is not in the network operator's interest. Unfortunately, it is also not in the phone manufacturer's interest to have you disconnect. Wake up, this is only a dream.
- enriquto 7y agothere is the librem5 phone that has these physical switches
- cf498 7y agoAlso the Pinephone if i am not mistaken, though it will be a few more month till thats available.
- rm_-rf_slash 7y agoWe need the same for cameras and microphones, too.
- coldtea 7y agoWell, cameras just need you to block them.
- autoexec 7y agoSoftware blocks aren't good enough because a compromised system can lie and say something is blocked when it isn't. Hardware disconnects you don't need to worry about.
- gwd 7y agoI think he meant put a physical cover over the lens.
- vuln 7y agoYou can still be fingerprinted based off the scratches on the lens. https://www.insider.com/facebook-patent-photos-fingerprint-dust-scratch-2015-9 https://www.insider.com/facebook-patent-photos-fingerprint-d...

- autoexec 7y agoI'm pretty sure I've seen similar attempts to identify a specific camera using things like sensor noise patterns and lens aberrations
- hutzlibu 7y agoMaybe, but more important, a potential hacker cannot see me nor my family anymore

- glitcher 7y agoOr put the phone inside a Faraday Cage phone pouch. Just because there is a physical control presented to the user doesn't mean there won't be any hidden connections inside the phone still.
- lucb1e 7y agoI've tested two of those. It's hit and miss. If it's not closed perfectly flat (and it's metal-lined fabric, it's not always perfectly flat even if you're careful), it'll receive phone calls just fine.
- m463 7y agoA faraday cage works for incoming signals, but not so much for outgoing. It also depends on the wavelength vs size of mesh. I think using a solid cage is the best bet.
- tareqak 7y agoHi 'm463, you seem knowledgeable about this subject, so I have a few questions. Could you please answer the questions below or direct me to where I can learn more? 1. If a phone is off e.g. iOS’s General->Shut Down, then can it still receive and transmit signals? 2. What is the best kind of cheap case / enclosure for a cellphone that would prevent signals from being transmitted or received? Can I just wrap a cellphone in aluminum foil and place said wrapped cellphone in a Tupperware / plastic sandwich container? 3. What is an effective way for an RF layperson like myself to detect whether or not my phone is transmitting or receiving signals while it appears to be off e.g. RF tool or measurement device? I just want a way to know and be completely certain that “off” means “off”.
- m463 7y agoThose are good questions and I'm not an expert. I was a part of a discussion once where someone mentioned that faraday cages mostly work for signals entering. However: 1a) You don't know (because your phone can pretend to be off). You need to remove the battery (and also remove hidden batteries) 1b) some phones support NFC, which can theoretically be used when the phone is off. 2) I suggest being familiar with: https://en.wikipedia.org/wiki/Faraday_cage https://en.wikipedia.org/wiki/Faraday_cage and your cellphone before making a decision 3) I don't know, but this would help with #2
- h4waii 7y agoIf you can't trust a manufacturer to make software that does what you're told it does, what makes you trust the same manufacturer to make hardware that will physically disconnect? Similar steps would have to be taken for monitoring the device to ensure the hardware switch does what it's told, same goes for the software.
