One of a nice feature with the dual screen of the LG G8X ThinQ I just discovered is the instant photo review on the dual screen after you take a photo.
If you have the camera on the main screen, after you take the photo, the dual screen will show the image of the shot that you just take.
The following youtube video illustrates this function:
It is such a nice feature that I do not need to press the button to view the photo in gallery, and I have less chance to miss my next shot.
Enjoy & Bye for now.
