`TextInput` emits `onChange` event with invalid `selection` on Android browser autofill

Inizia eseguendo il riproduttore obbligatorio con npm ci e npm start, quindi concentrati sul percorso dell’evento onChange di TextInput per l’autofill del browser/sistema su Android. Il lavoro è completato quando il testo compilato automaticamente segnala una selezione alla fine del valore inserito, mentre l’input incollato e il comportamento su iOS rimangono invariati.

Description

On Android, filling a TextInput via browser/system autofill emits an onChange event whose nativeEvent.selection is {start: 0, end: 0} instead of pointing to the end of the inserted text.

The text is correct, but the selection is wrong — the cursor is reported at the start of the field rather than after the autofilled value. The same input entered by pasting (from clipboard) reports the correct selection, and iOS reports the correct selection for both paste and autofill.

<TextInput
  autoComplete="tel"
  onChange={console.log}
/>

Expected vs. actual

iPhone 17 (iOS 26.5) — correct in both cases

✅ Paste +1 (555) 123-4567:

nativeEvent: {
  text: '+1 (555) 123-4567',
  selection: { start: 17, end: 17 }
}

✅ Browser autofill +1 (555) 123-4567:

nativeEvent: {
  text: '+1 (555) 123-4567',
  selection: { start: 17, end: 17 } 
}

Pixel 10 Pro XL (Android 17.0) — autofill is broken

✅ Paste +15551234567:

nativeEvent: {
  text: '+15551234567',
  selection: { start: 12, end: 12 }
}

❌ Browser autofill +15551234567:

nativeEvent: {
  text: '+15551234567',
  selection: { start: 0, end: 0 }
  //         ~~~~~~~~~~~~~~~~~~~~
}

On Android, autofill reports selection: { start: 0, end: 0 } while the text length is 12.
