Open the Camera app, tap the image thumbnail at the bottom of the screen, tap Gallery or Photos to view your photos, then tap Always or Just once.
Your photos are displayed in full size (in the orientation in which it was taken). Swipe or flick your finger left or right to scroll through your photos (or videos).
For quicker, direct access, you can tap the screen to display smaller, film-like images of your photos across the bottom of the screen. Swipe or flick horizontally to quickly scroll through them, then tap the one you want to view.
The pinch-to-zoom gesture allows you to easily zoom in and out of the displayed picture. Spread your fingers to zoom in and pinch your fingers to zoom out.
Continue the pinch in gesture on an image to display your photos in reduced size which allows you to swipe an image up, off the screen to quickly delete it, or swipe an image down to share it.
