What's New in Signal Beacon
1.2
October 3, 2026
Talk is more reliable. A call now carries on if the screen blips, and a phone no longer answers twice in a row, which could make it miss the other phone's reply. Talk runs the camera at 120 fps so phones stay cooler on longer calls. The full-screen camera's buttons now sit clear of the status bar.
