Here is the all-in-one thread on realmeXT camera testing. All quad cameras are tested in almost all modes. Scroll down slowly you might miss some important information.

Normal Camera Shots

Wide Angle Camera

This wide angle camera can help you to capture wide view without going back.

64MP Shots

The 64MP shots are the best detailed shots with which you can do wonders. You can crop in any part of the whole image and still the images will be usable with great details. Checkout my previous thread to checkout some 64MP shots here.

Portrait Mode (Back Camera)

Beautiful blurry background shots right? Perfect edge detection on the shots even in artificial lighting, thanks to the depth sensing camera on the back.

Panorama

If you need more wide shot than wide angle camera then panorama can help you and you can see the clarity of the pano shot.

Portrait Front

The edge detection is perfect. You can see even my glasses are perfectly in focus. The details on the face is perfect. However, the sky is blown out at the back.

Front camera (no portrait mode)

In this case, the sky is not blown out and face is perfectly in focus with all details preserved. Very nice color reproduction even the sky was bright.

Macro Camera

If you know how to use the macro camera, you can get some creative shots with this camera.

NightScape Mode

No noise, perfect color reproduction, details are preserved.

Even in 2x Zoom the night scape mode works flawlessly. Checkout how the flying Indian flag is perfectly in focus with all details and color preserved.
