With iOS 8 and earlier versions, Apple's default virtual keyboard was designed with uppercase letters, regardless of whether users input uppercase or lowercase. However, with iOS 9, the American technology company has made changes in the display style: when typing lowercase, the keyboard will display lowercase letters, and when typing uppercase, the keyboard switches to uppercase letters. Users can experience these changes after installing iOS 9 on their devices.

The new improvements make it easier for users to know the content they are about to input. However, if you were accustomed to the previous display method, you can revert to the old keyboard style by adjusting settings in the Accessibility section on your iPhone.
To do this on iPhone or iPad, go to Settings =>General =>Accessibility and scroll down to the Keyboard section. Here, if you want the virtual keyboard to always display uppercase letters, toggle the Show Lowercase Keys option to Off. When activated (by default), the keyboard will display lowercase and uppercase letters in corresponding changes.
