How do I turn off auto spell checkt?

[smoothrunnings]

I am getting tired of having to fight with my phone when I am typing messages to people. Today it decided to change the word crap into crappie. So how do I disable the auto spell check all together?

Thanks,

First, how ironic is it that you have a spelling mistake in the header when you are asking how to disable spell check!
Second, I'm looking at my s6 edge so it may be slightly different but it should be..... Settings > System tab > Language & Input > Spelling Correction

Or you could get a keyboard that learns words so it would recognize the word crap. I use swiftkey
