If you’re looking for a way to make your iPhone keyboard vibrate when you type, there are a few different ways to do it. The first option is to go to the Settings app on your iPhone and scroll down until you see Keyboard. Tap on it and then tap on Vibrate. You can now choose how strong the vibration should be, and whether or not it should happen when you hit the space bar or when you type a letter. If you want the keyboard to vibrate whenever you hit any key, including the space bar, then you’ll need to install a third-party keyboard app like SwiftKey. Once it’s installed, open up the app and tap on the Add New Keyboard button. From here, select Vibrate Whenever Key Is Pressed from the list of options. Finally, if all else fails and you just want your iPhone keyboard to vibrate whenever someone types in a message or reply on chat apps like WhatsApp or Facebook Messenger, then all you need to do is turn off sound notifications for those apps in Settings > Notifications > Messages & Calls > Keyboard > Sound Alerts. ..
