Hey @aman123,

This is really hard to read. Can you throw it in a Snack? Also, one preliminary thought is that if you haven’t ejected, you won’t be able to use the react-native-device-info library as it requires you to make native code configurations.

Cheers,

Adam

I think You can get unique expo token for mobile unique-ness.
then you can split string.

For Example :-

async getDeviceToken() {
const { status: existingStatus } = await Permissions.getAsync(
Permissions.NOTIFICATIONS
);
let finalStatus = existingStatus;

// only ask if permissions have not already been determined, because
// iOS won't necessarily prompt the user a second time.
if (existingStatus !== 'granted') {
  // Android remote notification permissions are granted during the app
  const { status } = await Permissions.askAsync(Permissions.NOTIFICATIONS);
  finalStatus = status;
}

// Stop here if the user did not grant permissions
if (finalStatus !== 'granted') {
  return;
}
// Get the token that uniquely identifies this device
// let DeviceToken = "";
try {
  let DeviceToken = await Notifications.getExpoPushTokenAsync();
  this.setState({ DeviceToken: DeviceToken });
  console.log('Our DeviceToken on login ' + DeviceToken);
} catch (error) {
  console.log('Our token error', error);
}

}

Output :- ExponentPushToken[XXXXXXXXXXXXXXXXXX]

sorry if i am wrong.
