Different devices, platforms, and tools have been available for years for screen mirroring, some of which are native to specific brands. The service of Samsung AllShare or AllShare Play was active for a long time, originally created for Samsung users to share available media files between tablets, smartphones, Samsung Smart TVs, and other associated devices.

With the support of AllShare Cast, users could play the media on the secondary Samsung devices when they are connected to one internet router. In terms of using the solution though, there are multiple factors one needs to consider. Here, we shall discuss them all, including other alternatives.

Part 1. What are AllShare Cast and AllShare Cast Dongle?

When speaking on AllShare Cast functionality for screen mirroring, understanding AllShare Cast Dongle is vital.

What is AllShare Cast Dongle?

The device comes as a small black-colored plastic box with an HDMI port within it that users connect to the display device, TV, or projector. The AllShare Cast Dongle works with USB connectivity support and has a lightweight build, which makes it a portable solution for network connectivity.

After applying the Dongle, you can stream different media content to your viewing screen from a compatible device. Since this is a device, users need to connect one HDMI cable end to the dongle and connect it to the TV with the other side in the HDMI socket.

AllShare Cast- Overview

In this context, the AllShare Cast app is a solution that Samsung smartphone users can use for screen mirroring. The app receiver allows the Android phone screen to display wirelessly after scanning on the Miracast-enabled screens and TV monitors, adapters, or Wireless dongles.

It is possible to activate this in-built feature on Samsung smartphones to activate the screen mirroring process from the adapter or dongle. Users have to swipe the top notification screen down on the phone and search for Search Mirroring. Then, click on it to activate the function.

Part 2. How to Use AllShare Cast?

AllShare Cast is a suitable solution for projecting the smartphone screen to another device in screen mirroring.

The AllShare solution from Samsung aimed to increase the limit of sharing digital media content across multiple devices, like computers, mobile devices, and TVs. It utilized DLNA for this, but Samsung has temporarily removed AllShare from its services.

However, instead of eradicating it, Samsung has merged the features of AllShare into other platforms, like Samsung Link. In recent times, the main solution in use is Smart View.

The newest SmartView is an application-centric solution with the combined effects of Samsung Link and AllShare. The newer versions have better UI conditions, improved speed, and more.

So, in the context of how to use AllShare Cast, you have to focus on how to use the Dongle and app together.

Using AllShare Cast Dongle

The most commonly used option for Samsung users adopting the AllShare Cast option is operating the Dongle device. It is a useful tool for streaming multimedia content like movies, music, and other types from compatible mobile devices into HDMI/HDTV displays.

To use this, you have to handle the whole setup process of the Dongle and then activate it for screen mirroring.

How to use it?

Step 1: Get the HDMI A-to-A cable you are using for this process and connect one of its ends to the Dongle. Enter the other cable end into the HDMI socket present on your TV.

Part 3. Is AllShare Cast Still Available?

Samsung's AllShare was useful for screen mirroring, but currently, it is inactive. After removing the service from its system, Samsung brought forward other apps with upgraded features and the functionalities available in the earlier AllShare Cast APK. These include solutions like Samsung Link, SmartView, and now the SmartThings app.

  • Android- Devices with Android 4.0 or higher.
  • iOS- iPhones running with iOS 7.0 or higher.
  • TVs- Samsung Smart TV models released after 2015 are compatible with Smart View typically.
