This also blocks me from using TextSecure&#x2F;Signal, because they require Google Play Services at run-time.<p>I&#x27;m using a BlackBerry OS 10 device, which can run Android apps, and I even have Google Play running on it, but Google Play Services is stubbed for a large part on BB10, making some apps (such as Google Maps, Google Calendar, and Signal) impossible to use.<p>Why a security&#x2F;privacy oriented application such as signals wants to bind so strongly with Google&#x27;s services, I don&#x27;t understand.
