The Samsung Bixby digital assistant lets you control your smartphone with voice commands. You can open apps, check the weather, play music, turn on Bluetooth, and much more. You’ll find everything you need to know about Google Assistant’s most prominent mobile rival below, including how to access it, the features it offers, and which devices it’s available on.

What can Samsung Bixby do?

The most interesting and helpful component of Samsung’s digital assistant is Bixby Voice, which lets you use voice commands to get stuff done. It works with all Samsung apps and a few third-party apps, including Instagram, Gmail, Facebook, and YouTube.

With Samsung Bixby Voice, you can send text messages, check sports scores, turn down the screen brightness, check your calendar, launch apps, and more. The digital assistant can also read your latest messages and speak in a male or female voice. The feature can also handle more complicated two-step actions, like creating an album with your vacation photos and sharing it with a friend.

Bixby Voice is the most helpful feature, but there are accessibility tools and others, as well.

Bixby Voice also supports quick commands, allowing you to perform multiple actions with a single phrase. Instead of telling Bixby to open the camera app, change the mode to super slow-mo, and start recording, you can pre-program all these steps as a quick command and launch it by saying “slow-mo.”

Another element is Bixby Home, which lives on your home screen. It’s similar to Google Feed, showing social media updates, trending YouTube videos, the weather forecast, reminders, and so on. You can customize it only to display the info you’re interested in and change the order of the Bixby Home cards by moving the ones that matter to you most to the top.

Bixby has a few other features, such as Bixby Vision, an alternative to Google Lens. Bixby Routines is another valuable component that learns your daily patterns to recommend actions right as you need them. There are also several accessibility tools for the vision or hearing impaired.

How does Bixby compare to Google Assistant?

Despite the efforts made with Bixby 2.0 (more on this later), Samsung Bixby still lags considerably behind Google Assistant, at least when understanding natural speech.

Bixby is quite powerful in controlling your device, like turning off Wi-Fi or enabling dark mode, but it struggles with context. Asking two related questions in a row will yield completely different results. It isn’t too surprising that Google Assistant consistently nails this, as, after all, it is made by the largest search engine in the world.

Bixby lags in general queries, but does have some powerful features like Bixby Routines.

We were underwhelmed when testing Bixby on the Galaxy S9 back in 2018 but came out pleasantly surprised when trying it again at the end of 2019. It still lagged in general queries, but the addition of Bixby Routines impressed us. It allows you to pre-program a list of actions using the ITTT (If This, Then That) principle. For example, one default routine saves battery life by turning off Bluetooth, Always on Display, Wi-Fi, and mobile data at night.

YouTuber Mrwhosetheboss ran a comparison of Bixby, Assistant, Siri, and Alexa in 2020, and the results put Bixby tied for last place alongside Alexa. It managed to answer just 27 out of 50 basic commands, whereas for Google Assistant, that number was 43.

How to use Samsung Bixby

Let’s start with Samsung Bixby Home. You can access it by pressing the dedicated Bixby button on a device that has one or by swiping right on your home screen. However, swiping right may also launch Samsung Free on certain devices. Free is a platform that combines books, podcasts, and video to keep you entertained at no cost.

If you keep pressing the button by accident, you can disable it. While it used to be impossible to remap said button, Samsung has allowed it to happen with some devices.

The same button that launches Samsung Bixby Home can also launch Bixby Voice. Press and hold it, say your command, and release it. It’s similar to using a walkie-talkie. Alternatively, you can activate it by saying, “Hi Bixby,” but you may need to enable this ability first by launching Bixby Home and going to More Options > Settings > Voice wake-up.

Which devices and languages does Samsung Bixby support?

Unlike Google Assistant, Samsung Bixby is exclusive to Samsung devices. It debuted on the Galaxy S8 series but is now all over Samsung devices. Here is a list of all supported devices at writing, but keep in mind that any Samsung device released after 2017 should have it.

Bixby-powered smart speakers, TVs, and other products are available as well

In addition to smartphones and tablets, Bixby runs on Samsung’s Family Hub 2.0 refrigerators and a couple of other devices. The digital assistant can also be found in other appliances like smart speakers and TVs. It is also slated to be a vital feature of the Samsung Galaxy Home, which has yet to release despite being announced back in 2018.

Bixby understands English (British, American, and Indian), Korean, Mandarin, Portuguese (Brazil), French, German, Italian, and Spanish. For comparison, Google Assistant supports 44 languages on smartphones and 13 languages on Google Home.

Bixby 2.0

In October 2017, Samsung announced Bixby 2.0, an upgraded version of its digital assistant, which launched on the Samsung Galaxy Note 9 in 2019. While there were some hiccups with the upgrade, it brought Bixby one step closer to competing with Google Assistant, Amazon Alexa, and Apple Siri.

Bixby 2.0 brought forth better natural language recognition, making it more conversational. Bixby users were previously limited to simple commands, like those listed above. Bixby 2.0 also included more languages and support for a wider variety of markets. It can even recognize users, learn about their habits, and better assist them with daily tasks.

The upgraded software was also an attempt to turn the digital assistant into a full-blown ecosystem for internet of things (IoT) and smart devices, hence the Samsung Galaxy Home, a smart speaker much like Google Home and Amazon Echo. This hasn’t entirely become a reality yet, although it is included in many new Samsung appliances.

In their efforts to further expand the digital assistant to the world, the Korean giant has also opened Bixby up to third-party developers. This allows for the creation of new apps, products, and services. The Bixby Marketplace launched in 2019 and has since grown to include custom capsules across all topics from finance to fun and games.

What is the Bixby Marketplace?

We mentioned it above, but the Bixby marketplace is a great way to take your voice assistant to a new level. The platform was first launched in the US and Korea in 2019. It’s the only place where you can download new Bixby features and make your assistant smarter. While it seems like Samsung should offer some of these integrations without an extra step, you will have to add certain elements like Samsung Email, Contacts, and Messages, or head to Google Duo for a video chat alternative.

The overall setup is similar to the Galaxy Store, where you can browse categories and add anything you like. You’ll also find recommendations for apps and skills on the Bixby Home screen.
