If you don’t want to use autocorrect on your iPhone, you can simply turn it off. In order to do this, go to your home screen and tap on Settings. From the Setting menu, tap on the “General” tab and scroll down until you see “Keyboard” and then tap on that option. You can then scroll down until you see “Auto-Correction” and then slide it from On to Off. You can always turn it back on later by following the same steps.
