We know you're smart. Therefore, there will be no teaching like select the screen you want to save or switch on your device. No nonsense. Just the necessary information how to make a screenshot on the Samsung Galaxy S21 Ultra phone.
Use buttons
Probably the easiest way to take a screenshot is to use the buttons. Simultaneously press the Volume Down and Power buttons and hold them down until you save a screenshot. You can use this method to make a scrolling screenshot.
If the first way to take a screenshot not work and you can't find picture let's go further.
Smart select
Samsung's Smart select option is really useful. It allows you to capture any part of the screen of the selected shape (square or oval) and still create GIF animation.
Bixby
You can also use the Bixby voice assistant to take a screenshot. Using Bixby is similar to Google Assistant.
Google Assistant
The slothful way is to use Google Assistant. Just say OK Google and then Take a screenshot. The gadget will do all the work for you.
Use apps
You can use additional screenshot apps which are a lot in Google Play: Private Screenshots, Screenshot touch, Screenshot Easy, Screenshot Pro, Screen Master etc... All these apps have instructions on how to use them to take a screenshot and save the picture.
Palm swipe
Just swipe the side of your palm from one side of the screen to the other palm from one side of the screen to the other (as if wiping it) to take a screenshot using the Palm Swipe. It doesn't matter whether you move your palm to the right or to the left.
Where do my screenshots go on? If you can't find the screenshots you took, don't lose heart. The places where the gadget saves screenshots and regular photo may be different. Again, it all depends on custom shells. A pure Android throws pictures into the gallery (DCIM). Other shells can save screenshots to a separate folder for your usability.
How can I share my screenshots? Depending on the Android version and the custom shell, sending screenshots may differ. In lastest versions of Android (9 or 10), the quick actions menu will appear after you take a screenshot instantly. There you need to choose the appropriate icon for sharing. Or just open the gallery app on your phone.
These methods work with gadgets of all operators.
