How to Screenshot on Samsung Dex: Quick and Easy Methods

Taking screenshots is a basic skill for anyone using digital devices, but it can feel confusing when working in a new environment like Samsung DeX. DeX turns your Samsung phone or tablet into a desktop-like interface, letting you use your device with a monitor, keyboard, and mouse. This gives you more flexibility, but it also changes how you interact with familiar tools. Screenshotting on DeX is not the same as on your phone screen—there are different methods, shortcuts, and even features you might not expect.

If you’re new to DeX, you might wonder: How do I capture what’s on my desktop? Can I screenshot a single app window? Where do my screenshots go? This guide will answer these questions and more. You’ll learn every practical way to take screenshots on Samsung DeX, find out which method suits your needs, and discover tips that make screenshotting easier and faster. Whether you’re a student, a professional, or just curious, this article will help you master screenshots on DeX.

What Is Samsung Dex And Why Screenshotting Is Different

Samsung DeX is a feature that lets you use your phone or tablet as a desktop computer. When you connect your device to a monitor, DeX gives you a Windows-like interface. You can open multiple apps, use a mouse and keyboard, and even drag-and-drop files. This makes your device much more powerful for work, study, and creative tasks.

But screenshotting on DeX is not the same as on your phone screen. On a phone, you often press the Power and Volume Down buttons together. On DeX, these buttons might control your device, not the desktop environment. Also, DeX lets you open apps in windows, so you may want to capture only part of the screen, not everything. The screenshot process changes because DeX uses a different interface, and the usual shortcuts don’t always work.

Why You Might Need Screenshots In Dex

• Sharing work: Send an image of your document, spreadsheet, or presentation.
• Reporting bugs: Show technical support exactly what’s happening.
• Saving information: Keep a copy of an email, chat, or website.
• Teaching and tutorials: Create guides or explain steps to others.

These tasks are easier if you know the right screenshot method for DeX.

Let’s look at each method in detail.

Using Keyboard Shortcuts In Samsung Dex

If you have a physical keyboard connected to your DeX setup, you can use keyboard shortcuts to take screenshots quickly. This is the fastest method for most users.

Full-screen Screenshot

Press Windows Key + Print Screen (PrtScn) on your keyboard. If your keyboard doesn’t have a Windows key, try Ctrl + PrtScn or just PrtScn. On some setups, the screenshot is saved directly to your device’s Gallery or the Screenshots folder.

• Tip: On some devices, the screenshot might go to a folder called DeX Screenshots inside your phone’s storage.

Partial Screenshot

DeX does not have a built-in shortcut for capturing a selected area. If you need this, you must use an app or tool (explained below).

Common Mistakes

• Not all keyboards have a PrtScn key.
• The shortcut may not work if your keyboard’s layout is not recognized by DeX.
• If nothing happens, check if your keyboard is connected properly.

Example

Imagine you’re working in DeX and see an important chart in your browser. Pressing Windows Key + PrtScn instantly captures the whole desktop. This is much faster than reaching for your phone.

Using The Dex Menu Screenshot Tool

Samsung DeX has a menu bar at the bottom of the screen, similar to Windows. This menu lets you control apps and settings, and it also has a screenshot tool.

How To Use The Dex Menu Screenshot Tool

• Look at the bottom right of the DeX screen for the DeX menu bar.
• Click the Screenshot icon (usually looks like a camera or scissors).
• Choose Full Screen or Window screenshot.
• The screenshot is saved to your device’s Gallery.
• Tip: If you don’t see the screenshot icon, make sure DeX is updated. Sometimes older devices hide this tool.

Advantages

• Easy to find and use.
• Lets you capture a single app window, not just the whole screen.
• Works even if you don’t have a keyboard connected.

Example

Suppose you’re editing a document and only want to share the window, not your whole desktop. Using the menu tool, you can capture just the document window.

Samsung Capture App: Advanced Screenshot Options

Some Samsung devices come with the Samsung Capture app, which offers extra screenshot features. If you use DeX often, this app can make your workflow smoother.

Features

• Scroll capture: Take screenshots of long pages (like websites or chat history).
• Edit screenshots: Crop, draw, or highlight parts of your screenshot.
• Share quickly: Send your screenshot by email, chat, or cloud storage.

How To Use Samsung Capture In Dex

• Open the app from your device (search for Samsung Capture in your app drawer).
• Click Screenshot or use the on-screen controls.
• Choose the area or window you want.
• Edit and save your screenshot.
• Tip: If you don’t see the app, update your device or download it from the Samsung Galaxy Store.

Comparison: Samsung Capture Vs Dex Menu Tool

Non-obvious Insight

Many beginners don’t realize that scroll capture works in DeX, not just on phone screens. This lets you screenshot entire web pages or chats in desktop mode.

Using Third-party Screenshot Apps

If you need more customization, there are third-party apps that work in DeX. Some popular options include Snip & Sketch, LightShot, and Greenshot (for Windows), but you must use Android apps compatible with DeX.

How To Choose The Right App

• Check if the app works in DeX mode.
• Look for features like area selection, annotation, and automatic saving.
• Read reviews to see if the app slows down your device.

Installation Steps

• Go to the Google Play Store or Samsung Galaxy Store.
• Search for screenshot apps (e.g., Screenshot Easy).
• Install the app and open it in DeX.

Example

If you need to annotate screenshots for a presentation, a third-party app can help. You can draw arrows, highlight text, and save in different formats.

Common Mistakes

• Installing apps that are not optimized for DeX can cause crashes or slow performance.
• Some apps require extra permissions; always check the settings.

Screenshotting With Phone Hardware Buttons

Many users try to use the Power + Volume Down buttons to take screenshots, as they do on their phone screen. This sometimes works in DeX, but there are limitations.

When It Works

• If DeX is running but your phone screen is active, the hardware buttons capture the phone display, not the DeX desktop.
• On some devices, the screenshot is taken from the DeX desktop and saved to the Gallery.

When It Doesn’t Work

• If your phone screen is locked or inactive, the hardware buttons may not work.
• The screenshot might capture only the phone screen, not the DeX interface.

Tip For Beginners

Try the hardware buttons, but if you don’t see the DeX desktop in your screenshot, use the DeX menu or keyboard shortcut instead.

Where Screenshots Are Saved In Dex

After you take a screenshot, you need to find it. DeX saves screenshots in different locations depending on the method.

Typical Locations

• Gallery app: Most screenshots appear here.
• Screenshots folder: Inside your phone’s storage.
• DeX Screenshots folder: Some methods use a special folder.
• Third-party app folder: If you use another app, screenshots may go here.

How To Find Your Screenshots

• Open the Gallery app on your phone or tablet.
• Look for the Screenshots album.
• If you don’t see it, use a file manager and search for Screenshots or DeX Screenshots.

Practical Example

If you screenshot a webpage using DeX, then want to email it, open the Gallery app, find your screenshot, and attach it to your email. If you use a third-party app, check the app’s folder.

Editing And Sharing Screenshots In Dex

Taking a screenshot is just the first step. Most users need to edit or share their screenshots. DeX makes this easy, but there are some tricks.

Editing Screenshots

• Use the Gallery app to crop, rotate, or annotate.
• If you need more tools, try Samsung Capture or a third-party app.
• For advanced editing, transfer your screenshot to your computer and use software like GIMP or Photoshop.

Sharing Screenshots

• Open the screenshot in the Gallery app.
• Click Share and choose your method (email, chat, cloud).
• If you use DeX, you can drag the screenshot directly into a chat or document.

Example

Suppose you take a screenshot of a spreadsheet in DeX. You can crop the image to show only the important data, then share it in a work chat.

Non-obvious Insight

If you use DeX with multiple monitors, screenshots usually capture only the primary DeX display. To capture other screens, use a third-party app.

Troubleshooting Screenshot Issues In Dex

Sometimes, screenshots don’t work as expected. Here are common problems and solutions.

Screenshot Not Saving

• Check storage space. If your device is full, screenshots may not save.
• Restart DeX. Sometimes, restarting fixes saving issues.

Screenshot Shortcut Not Working

• Try a different keyboard. Some keyboards don’t send the right signal.
• Update DeX. Newer versions fix many bugs.

Screenshots Are Blank Or Corrupted

• This can happen if the app you’re capturing blocks screenshots (for example, banking apps).
• Try capturing from a different window or use another method.

Example

If you press Windows Key + PrtScn and nothing happens, try using the DeX menu tool or check your keyboard connection.
