You can still preview. Just pull down on the icon or click the icon.Great tip! Didn't know you could do that. I tried it. I love how it looks. The white bars don't look very good. But I felt blind not being able to preview a text or swipe away other stuff. So I turned the white bars back on. Lol.
Thanks for sharing! I bet a lot of people here don't know about it. It's pretty buried. And I go through all the settings when I get a new phone.
