I am not a security guy, but I keep a tablet that is void of all personal information, uses no Google, Amazon services, has no email accounts on it, has no banking or financial applications, no pictures, no social media etc. It doesn't even have my name anywhere on it. The only thing that ties me to it is likely the wifi data that it stores. I also routinely will wipe it and start over.<p>Why do I do this? Well, it lets me have an anonymous web experience overall. I started it when I needed a way to test work I was doing but making sure that it was a "clean" experience. e.g. I didn't have something loaded or cached that would mess up my testing or the results. Then over time I figured out it is nice too because if someone needs to borrow a tablet for something real quick or needs to look something up I will hand it to them and I have no worries over anything they might see/do.<p>If I was doing security work, I don't think it would stop me from having a smart phone, but it would depend what type of security work. If being anonymous and hidden was the goal, I sure wouldn't have a smart phone, or any permanent phone for that matter.
I have an Android phone running Cyanogen. I mostly don't install anything ever (other than Signal).<p>No games, no social media apps, etc. I also have Spotify because I mostly listen to music rather than make phone calls.<p>I rarely browse the web on my phone, unless I'm testing a mobile application.<p>I refuse to install Telegram.
In my personal experience, the more I learn about security, the more cynical I become that privacy has any chance in modern society. There is a staggering amount of realtime, personally identifying (meta-)data available to a growing number of companies. It's truly scary, but I fear there is little to be done except prepare for the inevitable. Privacy is on its way to extinction. Adapt or die.
I am not a security guy but i use my smartphone as "walled environment" i do nothing on it that could potentially lead to issues except maybe some google services. But anything Banking or Bitcoin has never seen my phone at all.
in my experience security guys and privacy guys are very different people. Theres a lot of overlap in interest and skillset at lower levels but it usually diverges hard with experience.
