You can turn off the automatic formatting of quotes in the Settings app on your device. Changing the setting doesn’t affect existing hyphens and dashes in your document, only new text that you type. All you need to do is follow these simple steps on your device.
- Open Settings from the Homescreen on your iPhone or iPad.
- Go to General and tap on Keyboards.
- Find the option Smart Punctuation and tap the toggle slider to turn it off.
Now type as you normally do and see the quotes in straight, the quotation marks style takes effect immediately.
