You just got into a heated argument with someone.

You know from past experiences that they like to lie and make up stories about what you said or sent to them.

Now I know the Textra app has options under their settings, to back up all SMS & MMS.
However; you might want & need those messages saved straight away or need to pass them onto someone else before anything happens to them or your phone.

Instead; at this moment of you having to go to camera & then screenshot every single section to showing in order the conversation you had between the sender & receiver, you could send yourself (or anybody else for that matter), an entire email of your conversation.

From inside your conversation, you just press down on the screen & you get an option to email your conversation as it is on your current screen to yourself if it's set up that way or to someone else.

This way you have everything in order, it's one simple press and you have it saved already in your email account.
There's nothing to download or take up space in your gallery & you certainly don't need to get a perfect screenshot or maybe a few to capture all that is n your conversation.

I believe there would be many people, who could benefit from having this as an option, it saves also much time & space wasting.

Good Luck.
