How can I disable autocorrect for some languages in my keyboard?
The keyboard that comes with Samsung phones has this feature.

You can switch keyboards by pressing the little keyboard icon in the navigation bar, or by opening Settings, General Management, Language and Input, On-screen Keyboard.

You can configure the Samsung keyboard like this:


Open its settings by going to Settngs, General Management, Language and Input, On-screen Keyboard, Samsung Keyboard.
Open Languages and Types, and add the languages that you want to add.
Go back to the Samsung Keyboard settings
Open Auto Replace, and enable auto replace just for the languages that you want to enable it for.




I don't think it is possible to install the Samsung Keyboard on other types of Android phones.
