Do people know when you snapshot their texts on an iPhone?

If I was having a conversation on my iPhone with someone else who has an iPhone through text, and I wanted to screenshot something they said, would they know? I know on Snapchat if you screenshot a picture the other person gets a notification so I'm just curious

Nope! I have an iPhone and screenshot all the time over text! They don't get a notification like snap chat does! The only way they would know was if you told them you took a screenshot!

Yeah snapchat is a totally different story. With SMS apps on all devices there's no notifications sent to anybody. You can take a screenshot of any text message and nobody will know but you.
