rafichagran I’m on my phone (iPhone) too. It took me ages to work out a way to do it.
What I do is press the share button.
Then I ‘pretend’ that I’m going to share on Twitter.
A picture of my result appears and I do a screenshot and post the photo on here.
It doesn’t look as good as other’s pictures, but it’s better than nothing!
It’s very simple now that I know what to do.
I hope that this helps!
