iPhone locked when calling with headphones When calling I use my iPhone 5S with headphones on and it always gets locked during the call. This doesnt happen when calling phone to ear. Is there a way how to prevent iPhone to lock when having a call with headphones?
When you're on a call whilst wearing earphones the iPhone is designed to AutoLock, this happens with all iPhones not just yours. 

You can disable that feature from Settings➜Display&amp;Brightness and set it to never.
