If you haven't upgraded to iOS 11 yet, don't worry. It seems like this one isn't as popular as previous updates.

Users are upgrading their devices to iOS 11 at a slower rate compared to other recent updates, according to new statistics released by Apple.
Only 52% of devices have upgraded as of November 6, according to the company's website. While that's not a particularly bad start (and still significantly better than Android's), it's below previous updates.
By comparison, last year's iOS 10 update was at 60% by the end of October, after its release in September.
While Apple has given users plenty of reasons to upgrade, such as new emoji, ARKit-ready apps, and built-in screen recording, there are several other reasons why some may not want to make the update.
The iOS 11 update will break thousands of older apps that haven't been updated to support 64-bit processors. The update is also plagued with more bugs than usual, including a particularly annoying keyboard issue and battery issues. There's also the fact that some of iOS 11's best new features were only available on the iPad.
Between all of this and the general skepticism that many people have about new iOS updates, it's no surprise that users have been a little more hesitant about updating than in previous years.
