Copying a text conversation on a Samsung device is easy to do and can be done in just a few steps. To copy your text conversation, you'll need to open the Messages app and select the conversation you want to copy. Once selected, press and hold down on the conversation until additional options appear. Then select “Copy” from those options. The copied messages will then be available for pasting into another application or document of your choice by pressing and holding onto that page until additional options appear again, then select paste from those options
