7 Samsung ecosystem features that make the Galaxy S26 Ultra work better

The Samsung Galaxy S26 Ultra is a capable phone on its own, but it becomes even more useful when paired with other Samsung devices. Samsung has built a connected ecosystem where the phone, a Galaxy Watch, Galaxy Buds, a Galaxy Tab, and a Galaxy Book all share information and work together.

These are seven of the ways the Galaxy S26 Ultra fits into that ecosystem and makes everyday tasks across multiple devices easier:

The Samsung ecosystem is the group of Samsung devices — phones, tablets, laptops, watches, and earbuds — that connect and share information through a single Samsung account.

On the Galaxy S26 Ultra, this means files, audio, notifications, health data, and even your current task can move between devices automatically, without cables or third-party apps.

The value is in what a standalone phone cannot do: each feature below lets the Galaxy S26 Ultra hand off to, or pull from, the other Samsung devices you use through the day.

Samsung DeX turns the Galaxy S26 Ultra into a desktop-style computing device. When you connect the phone to a monitor or TV, DeX provides a desktop interface with resizable windows, a taskbar, and full multitasking, rather than simply mirroring the phone screen. Apps run in separate windows the way they would on a computer, and you can use a Bluetooth keyboard and mouse for input.

For the Galaxy S26 Ultra, DeX is useful when you want to work on documents, manage email, or handle multiple apps on a larger screen without needing a separate computer. The phone continues to function normally for calls and messages while DeX runs on the external display. It is a practical way to get desktop-style productivity out of a device you already carry.

Quick Share is a file-sharing feature that lets you move photos, videos, documents, and other files between your Galaxy devices. From the share menu on the Galaxy S26 Ultra, you can send files directly to nearby Galaxy phones, Galaxy Tab devices, and Galaxy Book laptops signed in to a Samsung account, without needing a cable or a third-party app.

Quick Share gives you control over who can send files to you through the “Who can share with you” setting, which can be limited to your contacts or opened more widely. For files that are too large to send directly or when the recipient is not nearby, Quick Share can create a shareable link instead.

There is also an option to allow sharing over the internet when a direct connection is not possible, so a transfer can continue using Wi-Fi or mobile data.

The Galaxy Buds4 keep your audio with you as you move between Samsung devices. Pair them once with the Galaxy S26 Ultra and they connect into the wider ecosystem.

Once paired to your Samsung account, the Galaxy Buds4 or Galaxy Buds4 Pro switch audio automatically between your devices through Auto Switch. If you are listening to music on the Galaxy S26 Ultra and start a video on a Galaxy Tab, the audio follows.

The Galaxy Buds4 series also support Live Translate^[4]. This feature uses the Galaxy S26 Ultra to translate conversations in real time and plays the translation through the earbuds.

Because the Galaxy Buds4 are configured through the Bluetooth settings menu on the Galaxy S26 Ultra, you can adjust noise control modes, sound settings, and earbud controls without a separate app. That keeps setup and adjustments in one place as you move between your Samsung devices.

Multi Control lets you use the keyboard and mouse from a Galaxy Book or Galaxy Tab to control your other Galaxy devices, including the Galaxy S26 Ultra.

This is not screen mirroring. Each device keeps its own screen and apps. You can move the cursor between devices, type on whichever one you are pointing at, and drag and drop files from one to another.

In practice, this means you can be working on a Galaxy Book, move the cursor onto the Galaxy S26 Ultra sitting next to it, and drag a photo or file directly from the laptop to the phone. Multi Control removes the friction of switching between separate input devices when you are working across a phone, tablet, and laptop at the same time.

SmartThings lets the Galaxy S26 Ultra control your smart home from one app. It is Samsung's smart home platform, built into the phone. From the SmartThings app, you can control compatible smart home devices, such as lights, plugs, thermostats, appliances, and cameras, and group them into routines that run automatically based on time, location, or other triggers.

Because SmartThings is integrated into the phone, the Galaxy S26 Ultra can act as a central control point for your home. You can check whether devices are on or off, adjust them remotely, and set up automations without needing a separate hub app from each device maker. SmartThings also connects with other Galaxy devices, so routines and controls stay consistent across your Samsung devices.

A Galaxy Watch paired with the Galaxy S26 Ultra extends the phone’s features onto your wrist. Notifications, calls, and messages come through to the watch, and you can respond to many of them without taking the phone out.

Health and fitness data the watch records syncs back to the Samsung Health App^[5] on the Galaxy S26 Ultra, where you can see the full picture in one place.

The integration also works in the other direction. Through Camera Controller, a Galaxy Watch can act as a remote viewfinder for the Galaxy S26 Ultra camera, letting you frame a shot on your wrist and trigger the shutter remotely.

Sleep tracking recorded by the watch syncs with the Galaxy S26 Ultra so the two devices build a combined view of your rest. Together, the phone and watch share data continuously rather than acting as two separate devices.

Continue apps on other devices lets you start something on the Galaxy S26 Ultra and pick it up on another Galaxy device. It is a set of handoff features that share your apps, clipboard, Wi-Fi, and camera between devices on the same Samsung account.

Continue apps lets you pick up apps like Samsung Notes and Samsung Internet from one device on another by tapping a button on the Recents screen. Copy and paste extends your clipboard across devices, so text, images, files, and videos copied on the Galaxy S26 Ultra can be pasted on a Galaxy Tab or Galaxy Book.

The feature also syncs Wi-Fi networks, so a network you have connected to on the Galaxy S26 Ultra appears on your other Galaxy devices for automatic connection without re-entering the password.

Camera continuity lets you take a photo or scan a document on the phone and continue working on it in an app like Samsung Notes on a computer. To use these features, the devices need to be on the same Wi-Fi network with Bluetooth turned on.

Individually, each of these seven features solves a specific everyday task. Together, they change how the Galaxy S26 Ultra fits into a day spent moving between devices. File transfers happen without cables, audio follows you between screens, your smart home is controlled from your pocket, and the work you start on one device can continue on another.

The common thread is the Samsung account, which ties the devices together. For anyone who already uses more than one Samsung device or is considering purchasing a Galaxy Watch, Galaxy Buds, a Galaxy Tab, or a Galaxy Book, the Galaxy S26 Ultra is built to work as part of that connected set rather than as a device on its own.
