Apple pushed the iOS 8.0.1 update in the early morning of September 25. After the upgrade, users encountered various problems. In the early morning of September 30, Apple officially pushed the iOS 8.0.2 system update. This upgrade fixes the problem that iOS 8.0.1 has no service on iPhone 6 and fingerprint recognition fails.
However, Apple's latest system is still causing trouble, and the latest iOS 8.0.2 upgrade is not enough. Many Apple users reported that there was a problem with the Bluetooth connection under iOS 8, especially in the car audio system. Mercedes Benz, BMW, Hyundai, Ford, Toyota, etc. were all attracted. In addition, the same problem exists when connecting wireless devices such as headphones and speakers through Bluetooth.
Although Apple has not officially responded, the technical customer service said that it has known the problem and will fix it as soon as possible.
Some users have found a temporary solution, a "stupid" and practical way: reset all settings of the device.
In this regard, the author can only say that please wait for iOS 8.0.3.
