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.
