Keyboard automatically dismisses when appropriate

A keyboard that lingers after form submit covers half the destination screen — users reach the home feed and see only the top row, then tap elsewhere to dismiss before they can scroll. On slow networks, this creates the impression that nothing happened after submit. Leaving the keyboard open during navigation transitions also makes screen-transition animations stutter on low-end Android because the keyboard reposition competes with the transition on the UI thread.

Call Keyboard.dismiss() at the top of every submit handler and on navigation transitions via React Navigation's beforeRemove listener:

import { Keyboard } from 'react-native';
const handleSubmit = async () => { Keyboard.dismiss(); await submitForm(); };
useEffect(() => navigation.addListener('beforeRemove', () => Keyboard.dismiss()), [navigation]);

Set keyboardShouldPersistTaps="handled" on any wrapping ScrollView so a tap outside the input also dismisses.
