Hello Mix44,
Thanks for that info and for choosing the Apple Support Communities. If I understand correctly, you are unable to use emojis on your iPhone in the keyboard as expected. First, make sure you have done this:
- Go to Settings > General and tap Keyboard.
- Tap Keyboards, then tap Add New Keyboard.
- Tap Emoji.
Use emoji on your iPhone, iPad, and iPod touch
Next, follow the steps in the section titled "If your display doesn't respond to touch" in this Apple resource and then contact Apple if you need any further assistance.
