Sometimes, a small tech problem can lead to something much worse. Here are some of the most critical problems ever caused by faulty software, hardware, and other errors.

When the iPhone 6 and 6 Plus first launched in 2014, some users reported that the phone bent after normal use, leading Apple to replace the affected devices. However, some reports said that the incidents were blown out of proportion.
