From the video

Answers: Why does a specific Instagram story crash phones and how can it be replicated?

• Instagram story phone crash bug
• Instagram post inspection
• HTTP proxy data manipulation
• Mobile app software vulnerabilities

What it concludes

• An Instagram story crashes Android and iOS devices because it contains element scale values with 18 digits, which are too large for phones to render.
• The massive element scale values are caused by someone using an HTTP proxy to intercept and modify Instagram story data before it hits the servers.
• Instagram fails to filter out excessively large numbers for sticker elements in stories.
• Older and lower-powered Android phones crash completely or become unresponsive, while modern high-end Android phones can handle or survive the rendering.
• iOS devices cannot render the large numbers at all and become completely unresponsive when viewing the story.
• The creator successfully replicated the crashing Instagram story using an HTTP proxy to scale sticker elements to astronomical dimensions.
