Stop Hangouts sending message when enter is pressed I have a Samsung Galaxy S4 and installed Hangouts (version 2.0.122) recently.  It is a great tool to organize all my messages together. However, it is quite annoying that it sends messages when I accidentally press enter, causing me to send unfinished messages.  Also I don't know how to insert a new line.  I looked into the settings but could not find any relevant options.

The iphone version treats enter as inserting new line so it does not have this problem.

Thanks for any tips you may have.
You can't change this. In Android, the app can tell the keyboard (or input method) what extra actions to show (such as Send). The app can also specify that the text field can only hold single-line text, as in this case.

What you could do is switch to a different keyboard app. You might be able to find one that puts the action in a different place (not in place of the enter key) that's harder to press by accident, or that completely ignores the action that's hinted by the app.
