See original GitHub issue

I have gone through these following points

Issue Description

Open app in Landscape mode and go to Picker. Click Picker, new screen with options opens. Select an option from the Picker items in the new screen.

node, npm, react-native, react and native-base version, expo version if used, xcode version

"expo": "^34.0.4",
"native-base": "^2.13.5",
"react": "^16.8.3",
"react-native": "^0.59.8",

Expected behaviour

After selecting an option you return to the main screen in the orientation you were before (Landscape)

Actual behaviour

App orientation is set to Portrait.

Steps to reproduce

import React, { useState, useEffect } from 'react';
import {
  Body, Right, Left, Icon, Header, Button, Title, Picker, View
} from 'native-base';

function LanguagePicker() {
  const [language, setLanguage] = useState( 'nl');

  function handleChangeLanguage(value) {
    setLanguage(value);
  }

  return (
    <View style={{flex: 1, height: '100%', justifyContent: 'center'}}>
    <Picker
      mode="dropdown"
      iosHeader="Select language"
      iosIcon={<Icon name="arrow-down" />}
      placeholder="Select language"
      placeholderStyle={{ color: '#000' }}
      style={{ width: '100%' }}
      itemTextStyle={{ color: '#000000' }}
      selectedValue={language}
      onValueChange={value => handleChangeLanguage(value)}
    >
      <Picker.Item label="Nederlands" key="0" value="nl" />
      <Picker.Item label="English" key="1" value="en" />
    </Picker>
    </View>
  );
}

export default LanguagePicker;

Is the bug present in both iOS and Android or in any one of them?

Only IOS, and only when in Landscape.

I tested this also on snack.expo (with own device, snack has only portrait mode!). Here is link to code: https://snack.expo.io/@anniekvandijk/language-dropdown
