With the release of the new version of the OS for the iPhone, many users were surprised to learn how many applications in their smartphones use Bluetooth without their knowledge. For example, Snapchat, ESPN and Dunkin 'Donuts (application of the popular fast food network in the USA - ed. Tekkult), each has its own goals and ignores the user's opinion by default. The new version of iOS allows you to directly prohibit them from doing this.
At Apple, the innovation is explained by concern for the safety of users. The space in large cities is literally overflowing with signals from Bluetooth devices, everywhere there are radio beacons, upon receiving a signal from which the module in the smartphone calculates and transmits its coordinates. This process previously took place outside of the control of iOS security controls, allowing for signal tracking and device location.
IOS 13 now has a direct function to control app access to the Bluetooth module. And developers, if they want to preserve their reputation, will have to clearly explain for what purposes this module is required to be included. They will have to be very convincing, otherwise the user may think: why do I need a software product that does not understand why it needs access to a wireless network?
