This is why Apple automatically activates one of the important functions of iDevices after each update

  Even if you use the system OTA Update al iOS 7 or a restore/update made via iTunes, after installing a new version of the operating system for our iDevices you will definitely notice that you have an important function activated automatically. I'm talking about the Bluetooth function, the company Apple Lossless Audio CODEC (ALAC), activating it automatically in case of every update, and if until now you have wondered what exactly motivates the American company to do this, well today we have an answer.

It's new to iOS7. it's a critical piece here. Without Bluetooth, iBeacons won't work. The 7.1 iOS makes a big push in what iBeacon can do, but Bluetooth has to be turned on. It's interesting to see how iBeacons are becoming a much more significant part of the Apple experience. The most recent iOS update extends the ability of an app to get location even if the app is not open. iBeacon now works when the app is closed.

  From the desire to make the system iBeacons popular, the Apple company automatically activates the function Bluetooth after each update, this system operating based on Bluetooth to provide information to the applications. Introduced last fall, iBeacons it is just starting to be used in US stores and Apple is trying to impose it on users by automatically activating the Bluetooth function after an update or restore. Unfortunately, there is no way to prevent this setting from being applied automatically, so you'll have to get used to it.
