MacRumors reports that Apple has today released another iOS 11 update with iOS 11.0.2, which is designed to fix, among other things, the crackling iPhone 8 and iPhone 8 Plus earpiece that some users have been experiencing when making phone calls and FaceTime calls.
Up until today’s update, the only way to circumnavigate the issue for those experiencing it has been to use headphones or speakerphone during calls or FaceTime. Now, hopefully, those affected should be able to resume making phone calls in the usual way free from any crackling or sizzling.
Another issue also addressed in today’s update is a problem that could cause some photos to be hidden, as well as a bug where attachments in S/MIME-encrypted emails won’t open.
There is, however, no mention of any fix for the battery drain issues that some owners of older iPhones have been experiencing (iPhone 8 and iPhone 8 Plus models do not appear to have any battery drain issues), so it will be interesting to see if the update has any effect on these problems.
