iOS 11.3 is expected to be more extensive than most mid-year updates, with new Animoji, battery health monitoring features, Face ID for family account purchases and more. But before that, users should see this bug fix, probably in the next week or so. Going forward, iOS 12 is expected to help iron out the many issues that have cropped up in Apple's mobile software recently. It may come at the loss of some new features, but that'll probably be worth it if Apple can avoid users getting stuck with crashing phones every few months.

Update 2/15/18, 4:30PM ET: Apple has confirmed that it is working on similar updates for macOS and watchOS that'll come out ahead of their next scheduled major updates. While we still don't have a specific timeframe, it seems this whole issue should be remedied before too long.
