In this case, the option finds in Configuration> Accessibility> Zoom.
An option provided to improve the visibility of the interface
If this box is marked, uncheck. The zoom function is used to allow us to expand certain elements of the screen, so it will have the main functionality to enormously obscure places that are not trying to see better. Except that if it is not approaching, it is the entire screen (the function is handled with three fingers playing the area three times).
To verify this, a very simple advice: if you make a screen capture by pressing the ignition button and the high volume at the same time, the screen will suddenly resume its usual brightness.
The accessibility option, very practical for people with a reduced view, is also activated by pressing several buttons on the phone. For example, if your iPhone cool in a bicycle medium with a housing and tightens the pendant, you can activate the option unintentionally.
In other words, before going to Apple Store, verify if your iPhone does not have a big technical problem, first verify accessibility options such as the zoom that would have enabled by mistake. Even if you will not be the only ones …
