iOS is a very stable and very fast operating system, compared to other operating systems present on smart mobile phones. However, it is not without bugs and moments when it leaves us in the lurch. It happens quite rarely, but it does happen.
The latest problem encountered with iOS 9 (9.3.4) installed on iPhone 6 was inability to use the flashlight function. Function flashlightThat LED room lights.
IPhone owners know that the "flashlight" of an iPhone can only be opened from control CenterBy dragging the bottom up outside display and reaching the first rapid application options bar. Flashlight.
Control Center looks like torch when not in use:
The problem is that the "Flashlight" button looks wrong as if the flashlight was on, and of course any attempt to turn on the camera LED was in vain. Basically the button became inactive, and the flashlight could not be turned on.
This bug occurs most often when The camera application is startedFunction Flash mode is enabled (ON) and the user leaves the application in the background. Flashlight applications si Camera I can run in parallel because both use LED.
Solving the problem lies in close all active applications which running in the background iOS (quickly double-tap the Home button si Swipe up across open applications), Then try again use Flashlight function.
If all else goes acted Flashlight button, turn (turn off) and reopen the iPhone. Everything will return to normal.
