使用react-native-localize获取设备国家名称异常：身处印度却返回美国的问题求助

各位好，我最近在React Native项目里尝试用react-native-localize搭配iso-3166-1-alpha-2获取设备所在的国家名称，结果碰到了个诡异的问题——我明明在印度，但获取到的国家名称却是美国，试了好几次都这样，实在找不到问题出在哪，想请大家帮忙看看！

下面是我相关的代码片段：

import { View, Text } from 'react-native'
import React, { useEffect, useState } from 'react'
import { NavigationContainer } from '@react-navigation/native';
import { createNativeStackNavigator } from '@react-navigation/native-stack';
import LogInviaPhone from '../Screens/LogInviaPhone';
import LogInviaEmail from '../Screens/LogInviaEmail';
import OTPScreen from '../Screens/OTPScreen';
import OTPScreenEmail from '../Screens/OTPScreenEmail';
import HomeScreen from '../Screens/HomeScreen';
import * as RNLocalize from 'react-native-localize';
import ISO3166 from 'iso-3166-1-alpha-2';

const Stack=createNativeStackNavigator();

export default function Navigation() {

  const [country,setCountry]=useState(null);

  useEffect(()=>{
    const fetchCountry=async()=>{
      try{
        const locales = RNLocalize.getLocales();
        const countryCode = locales[0]?.countryCode; 
        const countryName = ISO3166.getCountry(countryCode);
        setCountry(countryName);
        console.log('获取到的国家名称:', countryName); // 这里打印出来是美国
      }catch(error){
        console.error('获取国家信息失败:', error);
      }
    }
    fetchCountry();
  },[])

  return (
    <NavigationContainer>
      <Stack.Navigator initialRouteName="LogInviaPhone">
        <Stack.Screen name="LogInviaPhone" component={LogInviaPhone} />
        <Stack.Screen name="LogInviaEmail" component={LogInviaEmail} />
        <Stack.Screen name="OTPScreen" component={OTPScreen} />
        <Stack.Screen name="OTPScreenEmail" component={OTPScreenEmail} />
        <Stack.Screen name="HomeScreen" component={HomeScreen} />
      </Stack.Navigator>
    </NavigationContainer>
  )
}

我已经确认设备的系统区域设置确实是印度，也给了应用相关的位置权限，但结果还是不对。有没有朋友遇到过类似的情况？或者能指点下我哪里可能出错了吗？
