Apple notes that iOS 11.0.2 brings the following…
– Fixes an issue where crackling sounds may occur during calls for a small number of iPhone 8 and 8 Plus devices
– Addresses an issue that could cause some photos to become hidden
– Fixes an issue where attachments in S/MIME encrypted emails would not open
iOS 11 has added an array of new features, including a enhanced fully redesigned App Store. iOS 11 improves the Photos app by adding the ability to loop Live Photos, and to create long-exposure pictures as well as implementing a new compression method known as HEIF that offers higher quality images at half the storage size on devices.
Control Centre receives a huge redesign with the launch of iOS 11, putting all controls onto one page and adding 3D Touch capabilities. – Maps has a new feature called Do Not Disturb While Driving that uses Bluetooth and a Wi-Fi doppler effect to automatically enable a block to stop notifications from disturbing the user while behind the wheel.
