This Galaxy S21 camera guide explains what Galaxy S21 camera quick launch is, how to use it, and how to disable or enable it on Galaxy S21, S21+, or S21 Ultra.
Galaxy S21 camera quick launch is a standard feature of Galaxy S21. So it works identically on all three models of Galaxy S21 (S21 S21+, and S21 Ultra).
What is Galaxy S21 camera quick launch and how to use it?
Sometimes, you may need to take a photo or record a video as soon as possible because the perfect moment may go forever if you miss it.
But opening the camera app on Galaxy S21 by locating and tapping the camera app icon can take considerable time and therefore you may miss some precious moments.
Voice commands may let you open the camera app without looking at the screen. But it is not fast. The voice command (through Google Assistant, or Bixby) needs to be “processed” before it opens the camera app.

The fastest way to open the camera app on Galaxy S21 (and most Galaxy phones) is to use the camera quick launch.
Camera quick launch has been a standard feature in Galaxy phones for a long time.
In the old times, when there is a physical Home button (prior to Galaxy S8), you can double press the Home button to open the camera app.
Later, on Galaxy S8, S9, and S10, you can double press the power button to quickly launch the camera app.
On Galaxy S21 (and Galaxy S20), there is no physical Home button and no power button (which is combined with the unpopular Bixby button as Side key). The gesture for camera quick launch is to double press the Side key, as illustrated below.
By default, camera quick launch is enabled when you get the new Galaxy S21.
Please note, the Side key is located on the right side of Galaxy S21, above the volume rocker. You may check the Galaxy S21 layout if you need more info on the location of buttons and components.
Why is Galaxy S21 camera quick launch not working on my Galaxy S21 (or S21+, or S21 Ultra)?
If you find you can’t use Galaxy S21 camera quick launch to start the camera app, very likely, there are two possible causes.
Cause 1: You press the Side key too slow.
In this case, when you press the Side key twice, Galaxy S21 may simply turn off and then turn on the screen.
If this happens, it means the interval between the two presses is too long. You can practice it by speeding up the second press.
But if you press the Side key 3 times quickly, you will simply turn off (or turn on) the screen again. in this case, the camera quick launch does launch the camera app. But the screen is turned off (and possibly locked depending on your lock screen settings) when you press the Side key the third time. In a few regions, triple-press is assigned to emergency calls.
Cause 2: You assign the double press gesture to Bixby or other apps
Because Samsung allows you to customize the Side key gestures, you may assign the double press gesture to other apps.
In this case, after you quickly press the Side key twice, the assigned app, instead of the camera app, should open.
You can re-enable Galaxy S21 camera quick launch in two different locations:
- In Galaxy S21 Settings.
- In Galaxy S21 Power off menu.

You can also assign the long press (press and hold for about 2-5 seconds):

Anyway, if you want to re-enable the quick launch, you choose Quick launch camera.
There is a shortcut to access Side key settings page in the Power off menu.
By default, you can press and hold the Side key for about 2-5 seconds to access the Power off menu.
