Call a phone number from app (or text)? Is there way to call a number displayed on the phone (as part of text, although support for images would be nice too) that takes less steps than:


long press to switch into text selection mode
adjust selection begin and end to match the number
tap the "copy" icon
press/tap the "home" button
tap the Dialer icon
long press on the number field
tap "Paste"
tap the Call icon
?


I see there is an app that dials a number from the clipboard, but that only shaves off one or two steps.

Also this question is mentioned many times on the web, but I did not find any conclusive answer/solution.

Note: There is a similar question that is specific to phone numbers that appear on websites (and has no answers anyway).
Google Now on Tap
on Marshmallow does something similar but not perfectly

Long pressing the Home brings up the Google Now on Tap with various options , one of them being calling the number listed ( others being- text, share and add contact). The number gets pasted on the  telephone app without any user intervention. One can directly call from there


This is from a resturant search using an app. It works well in this case





This is from a random telephone directory search on mobile browser (details blacked out for obvious reasons). Here, it picks up only the first number, so this option is a hit and miss , if there are several numbers in the image
