How does Jolla compare to the newly introduced Blackphone? [not relevant]

Jolla has much to improve in terms of security, yet it's main advantage is the openness of the platform allowing to find and eventually patch the holes or at least point them out as can be already seen in this forum. Personally I don't believe this is possible with anything Droid-based.

Another thing which has come to my mind is baseband exploits. And this is a thing where Jolla and Blackphone can't do anything against. Except don't use known chips.

Android is fully open source, so dont have to trust it, you can check the source code yourself. If I remember right, source code for sailfish OS havent been released, this puts android ahead. And a top of that, blackphone has a lot nice security features.

@Cipher whoever compiles the release decides what is in it, and this is not necessarily the same as in the repository... I love OS, but IMHO it is not worth that much without a trustworthy company or person releasing it

@Cipher, what are you talking about? Google, as well as everyone that makes Android phones, are working hard on closing up as much of Android as they can (this is one of the reasons Google Play isn't available on Jolla - they don't want Android to be open). They do this by creating new, closed-source replacements for every Android components they can, and then all the manufacturers ship these closed versions instead of the open ones. While for SailfishOS, the source code for basically the whole base system is available as open source (it's called Nemo Mobile), except for some Jolla apps and add-ons. Not perfect, no, but how on Earth can you possibly say Android is any better than this?
