I think the best solution for fixing our everyday SMS problems would be to include an undo button. Everyone has sent that text that you never meant to send someone and things become really awkward. We can get rid of the risk of akwardness by putting the undo button.
This is the simplest way that we can fix this problem for ALL users. Everyone will know how to use an undo button. Anybody that has used a computer or other electronics should be familiar with the undo button. And it would be a simple click of a button. It is practical and it passes the “how can we make this more compatible for the laziest users test.”
