Android users aren't the only ones with a new beta update to play with today.
Apple has released iOS 11.4.1 beta 5 to developers and public testers. If you're a dev or just a regular user in the Apple Beta Software Program, you should be able to download this update by going into Settings > General > Software Update on your device.
There haven't been any major new feature found in the iOS 11.4.1 beta releases to date. That isn't surprising considering this is an x.x.1 update and iOS 12 is right around the corner, though. The update likely focuses on bug fixes and under the hood performance improvements, which isn't as exciting as a list of brand new features, but it's still important for devices that many people rely on day-to-day.
Apple hasn't said when iOS 11.4.1 will be released to the public.
