My keyboard freezes in messages

Thanks for posting in the Apple Support Communities bella928,

We understand the keyboard becomes unresponsive while typing messages.

The steps on the following page often offer a solution when an app, or feature within an app is unresponsive. Try the applicable steps and test to see whether there's any change: If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open

If the behavior is intermittent, or it eventually starts responding again on it own, try following the guidance outlined, here: About iOS performance on your iPhone, iPad, or iPod touch

We hope this helps!
