I am sorry but could you show me how to do it? for my note 5, on action memo after I write some numbers or email, I can select the numbers or email by pressing the button on the s pen, but on other newer Samsung devices with s pen, when I press the button on the pen, it will delete my writing instead of selecting my writing.
You just have to hover over the content you want to do the action on and a little icon will show depending on what the text is. So for example if it is a email address you will see a little envelope on the right side of the text. No need to press the button on the S-pen for the Note 8 it is as simple as just holding the pen over the text. Let me know if this helps.
it is weird that when I hover over the email address or some numbers, nothing appears nearby let me confirm with you again: you write some numbers or email in Samsung note, then save this note, then you use s pen to hover over the numbers or email then a little envelope will appear on the right side?, then you can click the envelope to save the numbers to contact or create an email?
