There are a few different ways to access (open) the Galaxy S21 Camera app, including:
- Tap the camera icon on the Home screen or Apps screen.
- Quickly press the side key twice (Quick Launch).

Method 1: Tap the camera icon on the Home screen or Apps screen
The traditional way to open Galaxy S21 Camera app is by tapping the camera icon on the Home screen (or Apps screen).

You can use the Galaxy S21 camera when the phone is locked. If you access the camera app when the phone is locked, you can take photos and record videos with all models and most of the settings.

Both Google Assistant and Bixby Voice can be used depending on your preferences.

The layout and contents of the Galaxy S21 Camera app
By default, when you open the camera app on Galaxy S21, the app will be in the Photo mode (or the last used mode if you turned on this option in Galaxy S21 Camera settings).
In the Photo mode (aka Auto mode), you will get the following layout, in addition to the navigation bar at the bottom if you are using navigation buttons (default).
1. Preview screen
The preview screen allows you to preview the scene before you press the shutter button.
In addition, you can use various touchscreen gestures on the preview screen (read on) to lock the exposure, zoom in/out, switch the front/rear camera, switch camera modes.
You can tap the shutter button to take photos.
If you hold the shutter button on Galaxy S21 Camera app, a short video will be recorded until you release the button.
Burst short photos (burst mode) can be accessed by swiping down the shutter button to the bottom. Up to 100 burst shot photos will be taken until you release the button (or until 100 photos have been taken).
3. Camera switch (front/rear)
You can use this button to switch between the front and rear camera.
of course, you can swipe upwards or downwards to switch the camera.
4. Shortcut to Gallery app
The thumbnail view of the last taken photo will be shown. You can tap it to open the Gallery app.
5. Camera modes
Although the default Photo mode (Auto mode) is sufficient for many situations, you may want to use different camera modes for some special events.
You can choose a different camera mode whenever you want. By default, only 3 camera modes (Single-take, Photo mode, and Video mode) are added for quick access. Other camera modes can be accessed by tapping the More button.
If you use some camera modes (e.g., Pro mode or Portrait Mode) quite often, you can add them for quick access.
6. Zoom and camera lens selection
Like Galaxy S20, Galaxy S21 supports hybrid optical zoom and super-resolution zoom.
By default, on Galaxy S21 Ultra, 4 pre-set zoom levels (0.6x, 1x, 3x, and 10x) are shown, as shown above.
You can tap any of the icons to choose the zoom level. At the same time, once you tap the icons, you will see more pre-set zoom levels up to 100x (Galaxy S21 Ultra).
If you pinch or spread on the preview screen, you will see the additional slider, as shown below, for you to control the zoom more precisely.

Galaxy S21 scene optimizer uses AI technology to optimize the camera settings for the given scene. Some effects may be applied automatically.
Different scenes and subjects including Face, Baby, Person, Dog, Cat, Food, People, Beaches, Sky, Mountain, Sunset, Sunrise, City, Snow, Waterfall, Watersides, Scenery, Stage, Vehicles, Drinks, Flowers, Trees, Greenery, Animal, Shoes, Backlit, Indoor, Text, Clothes and Night View, can be recognized by Galaxy S21 Camera app.
You can turn on or turn off the scene optimizer for the Photo (Auto mode) by tapping the button. Other camera modes (e.g., Portrait mode) may use it in different ways, and you cannot control it.
8. Enhanced focus
The Galaxy S21 camera does NOT have a dedicated macro mode. You can use the enhanced focus to improve photos with objects which are too close to the camera lens.
This enhanced focus icon appears automatically when the camera detects the close object.
As an alternative, you can zoom in when you want to take macro photos.

In the Auto flash mode, Galaxy S21 Camera app will enable or disable flash automatically based on light conditions.
Unless you are very sure, it is recommended to turn the LED flash off.
11. Timer
When it is inconvenient to tap the shutter button, you can use the timer (or voice control) to take photos.
You can set the timer of 2, 5, or 10 seconds for Galaxy S21 camera.
When you take photos in very low light conditions or use zoom levels higher than 20-30x, you may get blurry photos easily. In this case, you can consider using a timer (and a tripod).
12. Photo size
On Galaxy S21, you can only set the aspect ratio of the photo, not the size (resolution) of the photo. For each aspect ratio, Galaxy S21 will use the maximum resolution at that ratio.
The supported photo size (aspect ratio) on Galaxy S21 Camera app includes 4:3 (best for printing), 16:9 (best for TV/ digital photo frame), 1:1 (for design. Instagram), and 20:9 (full screen)

When sharing photos, you have the option to share the Motion Photo as a video file.
14. Effects/filters
You can add effects (filters) to the photos to be taken.
Of course, you can add effects when editing them. But some owners may prefer to add them when taking the photo.
