If the friend whose name does not appear properly is saved in your device’s contacts list, it is possible their name contained an emoji when it was saved.
Check your contacts list. If your friend’s name was saved with an emoji, please try deleting it.
If the issue persists after trying the above, please refer to the following steps:
- Go to More > Settings.
- Tap Friends.
- Turn ON Add Friends.
Note: If the option is already turned ON, tap the refresh icon next to the last synced date to manually sync your contacts.
