Watching videos on your iPhone is typically a pretty harmless experience, but a new, strange video going around is an exception to the rule. As Redditors discovered, one unusual three-second clip will actually lock up virtually any iPhone, requiring owners to hard reset their device before they can use it again.
The video only seems to take effect when the a particular .mp4 video file is viewed in the iPhone’s native media player. The clip, shown playing on an iPhone above, plays normally including sound and appears to be a normal video at first blush. However, those who play it will find that over the course of the next 30 seconds or so, their device will slow to a crawl before freezing completely.
