How do you (can I) copy and paste texts and/or links on an Android cell phone?
Press and hold on the text.
On my Android, I just press down on the screen over the text and hold it for a couple of seconds. A menu comes up with the option to copy text. I do the same in a new message to paste.
Dunno if yours is different, I’m not all that tech-savvy.
Just to expand a bit, once you press and hold on the text, two selection cursors will appear. You can drag those around to change the selected text. Then you click inside the selected text to tell it what you want to do with that, such as copying it or sharing it.
thanks
Unless you are like me and for some reason your fingertip is detected as the size of montana and you cant reliably move the things 
You’re hardly the only one 
I think that’s why iOS gives you a magnifying glass when you try to select.
It’s annoying as all heck.
I’m still on 5.0, but I suspect the OP may be referring to the fact that long pressing a text message to do this doesn’t work, or at least it has never worked for me. In order to copy the subject or body of an incoming text message, I have always had to tap the “Forward” option in the menu–i.e., pretend I want to forward it to someone, and then in the editing window I am able to select and copy from the text message, as for most other types of displayed text.
I’m on 5.0.1, and if I long press a text message, a box pops up with options like “Forward,” “Delete,” etc. One of the options is “Copy text.” When I tap that, it copies the message to the clipboard.
Same issue here (toe thumbs). It used to drive me crazy when trying to text and then I found a keyboard calibration feature on my phone (HTC) buried in the settings. Helps out quite a lot.
