You can see whether you’ve sent a text or a chat – most devices show them in different colours.
In similar fashion to Instagram, Snapchat has filters or lenses which you can add to your photos.
Otherwise messages will be sent as text or picture messages.
(This function isn’t supported on i OS.) You’ll always know which type of message will be sent (text, picture message or chat) before you send it.
Check your Play Store’s app to update your Snapchat app, or App Store if you are using i Phone or i OS devices.
Take a selfie with your pretty full face, actually you don’t have to look pretty, because you face will be switched.
