TextSecure 是一个安全增强文本消息应用程序，用于完全替代默认文本消息应用程序。 无线发送给其他 TextSecure 用户的消息都经过加密，同时所有文本消息都存储在设备的加密数据库中。 如果电话丢失或被盗，您的消息将保持安全，同时无法空中监控与其他 TextSecure 用户的无线通信。 更新内容： ★ You wanted an even better camera. Picture this: • Never miss a moment. Take higher-quality photographs and capture them up to three times faster. • Hold still, focus on your breathing, then tap to focus on something that takes your breath away. • Add a pinch of zoom with gestures that let you get closer to the action. ★ Quickly see the progress of large file uploads (10mb+) in your notification tray. ★ Support for incoming call notifications on Android Q.
