Androïd smartphones are consumer-grade devices, so security vulnerabilities are aplenty.
High-ranking officials in the government, FBI agents, etc, need a device capable of end-to-end encryption.
So a good number of people needing end-to-end encryption are using a Blackphone.

If you ever considered that your privacy is worthwhile, then you may find that you are not well served with an Androïd device.
Data is a commodity these days, and some obscure companies are more than happy to profit from this. And when you take into account cyber-criminality, it is millions, even billions, of dollars that are drained from legal economic activities.
No wonder, then, that people who know better are taking the privacy issue seriously.
Introducing Blackphone
Much of what your cell phone sends cannot be encrypted or the cell phone system couldn't work. For instance, the phone number you're calling has to be sent in the clear. Also your phone number and location to the nearest cell tower, so the system can forward calls to your phone, and know where you are in case you make a 911 call.
