What's New in Zero Secure Messenger

1.2.0

September 4, 2026

What's New in Version 1.2.0: Share into Zero from anywhere Send photos, videos, documents and links to Zero straight from the iOS share sheet — and pick the chat right there. Send documents The Files option in a chat now works. Attach any document from iCloud Drive, your device or another app. Call from your contacts Press and hold a contact to start a voice or video call. Screenshot protection Screenshots, screen recordings and AirPlay now come out blank while Zero is open. On by default; you'll find the switch under Settings › Privacy. Fixes • Times follow your device's 24-hour setting throughout the app • Photos sent without a connection now arrive as photos, and disappearing messages stay disappearing • Media uploads no longer disappear when a message arrives mid-upload; failed uploads can be retried • Tapping a notification opens the conversation it's about • Cancelled calls are listed as cancelled instead of completed • Groups move to the top of your list when you send in them • The typing indicator no longer flickers off while you're still typing • No more duplicate notification banners for the same message • Safety numbers no longer report a mismatch before your first message is exchanged • Zero IDs pasted from a message or email are accepted • Signing in with a different licence no longer shows the previous account's data • Far fewer unexpected sign-outs
