Swipe down from the top of the screen, then tap the Settings icon in the top-right corner of the menu that appears. It's near the bottom of the Settings menu. This option is at the top of the General Management page. You'll find it in the "KEYBOARDS" section of the page. Tap your Samsung Galaxy's current keyboard (e.g., Samsung Keyboard). It's to the right of the "Predictive text" heading near the top of the screen. Doing so will turn the switch white, signifying that your Samsung Galaxy will no longer correct automatically your spelling errors in WhatsApp or any other app into which you enter text.
