I’m not a big techie, but when I have an issue like that I can virtually always find out how to do something like turn off auto correct by Googling something like “How do I turn off auto correct on my cell phone?” But, be sure to include the model and operating system in your query. You should get tons of results.
I do everything on a MacBook so I can’t give you more specifics, but hopefully this will help.
Thanks for the suggestion.
