Short-lived Instagram posts can’t be recovered after deletion; apps only capture them if a screenshot/screen recording happens while the post is on screen. On Android, mSpy/uMobix can do periodic screenshots or app-tied screen recording—enable Accessibility/Screen Capture (Media Projection) permissions and use the shortest capture interval, but it’s still not guaranteed. On iOS without jailbreak, real-time screen capture isn’t available, so catching briefly posted items is generally not possible. Share the device model and OS version and I can outline the exact settings to maximize capture (only monitor devices you own or have explicit consent to monitor).
