Hello to all. We purchased two iPhone 11 pro and one 11 Pro max. With IOS 13.0 the devices worked well, after updating to IOS 13.1 or 13.1.1 or 13.1.2 strange bugs occur. Even if in the privacy section all the system localizations, find my iphone, and all the app localizations are disabled, iphone continuously connects every 10-20 seconds to the gps network, consuming a lot of battery, it can be seen from the triangle that appears top left. Many users do not notice it because maybe the function that warns when the GPS transmits data is not activated. But I assure you that there is this serious bug and I ask you to all those who have an iPhone 11 pro and pro max of go to settings, privacy, location services, system services and activate status bar icon. You will see the iPhone 11 pro connect continuously to the GPS. In the apple store they changed my devices but it didn't help. Now I am waiting for a call from a consultant to whom I have also sent a video of the problem. I also found other people online with this problem and please check it and report it to us and to Apple. Thanks
