Fair point. In the case of ultra-portable devices (that are all the more easily stolen) there should be a measure of physical security though. I also use the iPhone 6 example because the San Bernadino shooter's 5S was physically confiscated by police. This being said, wireless vulnerabilities are indeed a high priority. You're probably already aware of the various vulnerabilities suffered by Broadcom Wi-Fi chipsets used in almost all phones.

Your concerns regarding cellular encryption are made all the more valid because of the extremely high political sensitivity of surfacing _anything_ that would even remotely suggest that encryption is not being used (classical security by obscurity). Someone asked for a cellular encryption indicator in Android 9 years ago, and I thought the response they received was very very insightful and gave a lot of food for thought. Slowly reading between the lines of every official reply is necessary. https://issuetracker.google.com/issues/36911336 https://issuetracker.google.com/issues/36911336
