Four cameras to document your life

To be by your side at all times, the camera goes out of its way. Capture stunning photos with the 64MP main camera, or choose the 123 ° angle of view on the 8MP ultra-wide angle lens for wider shots. With the 5 MP depth camera, you can get a blurry effect in the background, while with the 5 MP Macro camera you will have perfectly focused close-ups. 

 Broaden your perspective

Use the ultra-wide-angle camera to take larger shots. With the 81 ° wide-angle and 123 ° ultra-wide-angle you can capture the scene in front of you, wherever you are, without missing the moment. Photographing breathtaking views has never been easier.

Capture every micro detail with the Macro camera

The built-in 5MP Macro camera takes sharp, quality shots to bring out every little detail of your close-ups. You can also apply and adjust background blur (Bokeh effect) to enhance your subject with maximum visual impact.

Explore deeper

The 5MP depth camera allows you to adjust the depth of field before and after shooting. Plus, it reduces unwanted background noise for true pro shots.

Show your best side with the Galaxy M31's 32MP front camera. And to have all the spotlight on you, turn on Live Focus to blur the background for a flawless portrait, in the park or in a cafe.
