iPhone, iPad and iPod touch users can now download iOS 11.4.1 update for their devices over the air. You can also perform a clean install if you like.

iOS 11.4.1 has been in beta for a long time. And for a small point update, that’s rather unusual, but not surprising at all since Apple has been doing it for quite a while now. But the highlighting news is that you can now download iOS 11.4.1 right now and we’ll highly recommend updating to it since it is a bug fix release that aims to improve the stability of your iPhone, iPad or iPod touch.
