Do you know the movie Citizenfour, a documentary about Edward Snowden? During its production, if the filmmakers wanted to discuss something sensitive, they would leave their phones in the office and go outside to have their conversation without them. There still might have been listening devices around, but they did what they could about the phones.

A great point for the current scenario. The way smartphones have penetrated our life is of epic proportions. One needs to keep an ever opened watchful eye while using any smart devices.

I’d consider it unlikely that Google or Apple put anything like that into their phones on purpose, because of the reputational hit if it came out.

True true …Very true
