Some texts automatically underlined in iPhone 5 with iOS 7.1 I am using iPhone 5 with iOS 7.1, My problem is text automatically underlined on some buttons in the application 



Is there any settings available to remove the underline? Or how to fix this issue ?
This is a change to show which button labels are pressable.

You should go to Settings &gt; General &gt; Accessibility and turn on/off Button Shapes and then revisit the app in question. You should only see underlines and shapes when this control is on, and this is to indicate what buttons that look like text are actually tappable for those with accessibility needs.
