The iPad and iPhone don’t freeze or crash often, but when they do it can be an epic freeze-up, where the device can either get stuck in an app or, worse, it gets frozen on the dreaded iOS “spinning wheel of death”, the little wait cursor that never goes away. Left on it’s own in that state, that spinning wheel can quite literally spin forever until the battery drains and the device dies out, but that’s obviously not a solution to resolve the rare major iOS crashes. We’ll cover three tricks to fix major iOS crashes, the first will attempt to just exit out of the crashing application, the next will forcibly restart the device, and finally for the worst scenarios, we’ll restore iOS as new, though that really should be a last resort that is rarely applicable to most situations.
If you’re a heavy command line user, you’re probably well aware that the arrow keys can be used to flip through previously executed commands and the tab key can complete them.
