Threema for Android Introduces Group Calls

When Threema was first released almost ten years ago, it was a chat-only app. These days, however, many users have come to rely on it for secure and privacy-compliant phone calls, which don’t require to disclose a phone number. Expanding Threema’s feature set further, the 4.9 update allows Android users to conduct audio/video group calls of up to 16 participants.
