How to use Samsung DeX on the rugged Galaxy Tab Active3

The Samsung Galaxy Tab Active3 is a rugged tablet designed for frontline workers on the go. With a durable protective case and shatter-resistant screen, the Tab Active3 has been put through a series of durability tests based on the U.S. Department of Defense’s MIL-STD-810H standard to prove its toughness. It’s also IP68-certified for dirt, dust and water resistance.

But despite its rugged exterior, the Tab Active3 packs some serious smarts, including Samsung DeX — a powerful mobile computing platform that lets the tablet power a PC-like experience on an external monitor. The DeX platform is built in, so you just connect the Tab Active3 to a compatible monitor and pair a keyboard and mouse for an intuitive desktop environment.

Having DeX on the Tab Active3 is ideal for frontline workers who occasionally need to complete reporting or other productivity tasks. They’ll no longer need a separate laptop or desktop computer, and can use their tablet throughout the day. In addition to simplifying workflows, this device consolidation can result in significant cost savings.

Here’s how DeX works on the Tab Active3:

Using DeX on the Tab Active3

For any display with an HDMI input, you can connect the Tab Active3 via an HDMI-to-USB-C adaptor or cable. You can also connect wirelessly to displays that support Miracast, including most Smart TVs and Samsung’s new Smart Monitor.

  1. First, power on your display, and go to the Sources menu. Then select the HDMI port where you’ve connected the cable. For wireless DeX, select Screen Mirroring.
  2. Now, on your Tab Active3, pull down the quick panel menu from the top of your screen, and tap the DeX option.
  3. Your tablet will now search for available displays to connect with wirelessly. When you see your display listed, tap it.

DeX will now launch on the external display, giving you a desktop-like interface to access all your mobile and web apps.

If you’re just sharing or viewing content, you can navigate within DeX by using your tablet as a touchpad. Pull down your notifications menu and tap the touchpad option.

Pair a Bluetooth keyboard and mouse

For productivity work in DeX, you can pair a Bluetooth keyboard and mouse.

  1. First, open your Bluetooth settings from the quick panel.
  2. Then put your keyboard into pairing mode following, the manufacturer’s instructions.
  3. Now, select the keyboard’s name on your Galaxy device’s Bluetooth screen.
  4. Repeat these same steps for your mouse.

Samsung DeX gives you a desktop-like experience to work across multiple apps simultaneously. Key productivity apps like Microsoft Office are optimized for DeX. You can even drag and drop files, and right-click on items to pull up context menus. VDI clients from Citrix, VMware and Amazon are also optimized for DeX, so you can run your virtual desktops too.

You can also continue to use your Galaxy Tab Active3 while it powers the DeX experience on your external display, effectively giving you two screens.

Added benefits

With the rugged Galaxy Tab Active3 featuring Samsung DeX, frontline workers can stay productive on the go — and when they return to their home office.

Because it is running on the Tab Active3, Samsung DeX provides full connectivity to the web via Wi-Fi 6, or LTE if you have a carrier-connected tablet.

The bottom line: With the Tab Active3 and Samsung DeX, frontline workers can access desktop functionality whenever they need it. Then, they can disconnect the Tab Active3 to do field work in the most demanding of weather and working environments.
