Discover Hidden Modes Transforming Your Samsung Galaxy Phone


For a long time, I treated my smartphone like, well, a phone with just a few extra features. Sure, I could browse the internet and work on documents, but I largely relegated my mobile device to being nothing more than a phone.

Then I discovered the hobby of tinkering with Android and doing experiments in my makeshift home lab. After that, I saw the phone as an extension of my computer or something to use for making things.

I rounded up a few of my favorite “hidden” or lesser-known features that I think are worth checking out once you know how to find them (and if you have a Samsung Galaxy device, of course).

I’m using a Samsung Galaxy Z Fold 5 running One UI 8.5 for these features. Most Samsung Galaxy phones will likely have similar features, but your results may vary.

There are other foldables, but none quite like this.

Samsung offers a unique mode called DeX Although it’s easy to access, it’s probably not something you’ve thought about much from day to day. If you’re lucky enough to have a Samsung phone that offers it, DeX can be a game-changer for productivity. It’s compatible with Bluetooth keyboards and mice, too, so it acts as a way to conveniently use your phone as more of a “desktop experience.”

On my phone, it was accessible straight from the top menu. Wireless DeX is available on devices made after 2018. Fortunately, my device fell into that category. That doesn’t mean DeX is dead. It just means that the classic DeX layout has been overhauled to align better with multi-window use. It’s a positive evolution for a useful feature that makes it even easier to simulate a desktop experience with your phone.

You can also use an adapter cable to connect your phone to any HDMI display, should you prefer to go that route. DeX on PC allows you to hook your phone up to a PC to use DeX with a USB cable.

Compatibility can be an issue, so check your device on this handy list of compatible devices straight from Samsung.

Experimental features that transform your device into more than a mere phone

Samsung Galaxy phones often include a somewhat hidden feature called Labs. They are, just as the name implies, experimental features specific to different Galaxy phones. According to Samsung itself, some of the apps may not work correctly. To find and enable Labs, just navigate to settings > search > labs. From there, you’ll be able to see what’s available on your phone.

My Labs menu only showed dark mode, Multi-window for all apps, and Landscape view for portrait apps, but when you click into Multi-Window, it offers other useful Labs features like Swipe for split screen (which is incredibly handy in unfolded mode) and Swipe for pop-up view (which I find significantly less handy and don’t really use).

I use my Samsung for hobby projects, composing, some light coding, budgeting, and work-related tasks, so multi-window is one of my most frequently used features. I accidentally discovered that if you take a screenshot in multi-window mode with this feature on, it lets you either keep the image of both apps open together, or you can grab a screenshot from only one of the apps.

I also recommend enabling Landscape view for portrait apps. If you’re like me and you use landscape mode frequently, then this is a fantastic feature for both folded and unfolded modes. I don’t really need to talk about dark mode, but it is available, and I use it on basically everything.

On non-foldable phones, Labs will offer different features depending on make and model.

Flex mode converts your phone into a tiny laptop

Have you ever wanted a tiny laptop? Of course, you have! Flex mode provides something like that. So, this is technically an advanced feature (found under settings > advanced features > Flex mode panel) that can be enabled the same way as the other features I mentioned before. The idea here is that you put the phone at an angle, so the top screen is essentially perpendicular to the bottom screen.

It has some unexpected features, like a touchpad on the bottom screen that gives you a mouse pointer so you can navigate your phone as if it were a computer (there’s no mouse button; you have to tap the screen to act as a ‘click’). You can also bring down the overlay, take a screenshot, or open a different app on the bottom screen with just a simple tap.

It works for me because I write a lot, have to take a variety of screenshots, or just like to mess around with experimental features on my phone. I like this mode almost as much as multi-window.

I Didn’t Start Buying Samsung Phones Until They Got Boring

This is the most excited I’ve ever been to buy Samsung phones.


Samsung phones are powerful computers

Experimental features truly made a difference for my phone, but they’re only the beginning of what can be done with Android. In the past, I’ve turned old Android devices into dedicated music players, converted one to an on-the-go laptop surrogate, and set up an old Motorola as an Android TV hub.

Hidden and experimental features are half of the fun of owning a powerful computer that you carry in your pocket. Sometimes, it makes the world feel a lot more like Star Trek every day (I’m a Next Generation and Titan fan, myself).

Recent Reviews


I am a recent convert to physical media — yet even as someone getting back into buying discs in 2026, I haven’t been buying Blu-rays. Like many Americans, I still pick up DVDs instead. These aren’t great times for the Blu-ray format, and don’t expect a turnaround in 2026.

Fewer new releases make their way to Blu-ray

More media is now released exclusively for streaming

Blu-ray has been around for two decades, but it never managed to fully replace, or even overtake, the DVD format it was designed to supersede. We still can’t take for granted that our favorite movies, let alone TV shows, will eventually see a Blu-ray release.

The movies most likely to come to Blu-ray are the ones that hit theaters, but a growing amount of cinema is designed exclusively with streaming platforms in mind. I recently rewatched Mississippi Masala, which led me to check in on what work Sarita Choudhury has done over the decades since. A film called Evil Eye released in 2020 caught my eye. Unfortunately, it’s only available via Prime Video. There’s no Blu-ray or even a DVD. In contrast, it’s easy to watch Michael B. Jordan in Sinners on Blu-ray, since that movie came to theaters last year.

You could say that it makes sense that a movie with a 4.8/10 rating on IMDb doesn’t see a physical release, but in the heyday of physical video, store shelves were stacked not only with just the big-budget bangers but plenty of straight-to-DVD movies as well. Now those films exist to pad out streaming catalogs instead.

Fewer big box stores stock their shelves with physical discs

Blu-ray discs have disappeared from some stores entirely

The format’s demise is striking. I frequent my local Best Buy quite often and don’t see any movies on display. That’s because the retailer stopped selling movies in stores several years ago. Walmart still sells them, but the selection is a fraction of what you could find ten or twenty years ago. The audience has been reduced down to the shrinking number of people whose internet at home can’t handle streaming and those who might think of themselves as collectors.

If you venture onto Reddit and visit r/Blu-ray, you will find more threads about thrift store hauls and older collections than excitement over the latest new release. Don’t get me wrong — I, too, am very excited about seeing what gems I can snag for only a couple bucks, but this shows the challenge retailers face. Increasingly, only enthusiasts are prepared to drop over $20 on a disc.

I’m not buying discs to stick them in a player

The simple truth is that most people don’t want to buy physical media. Discs don’t fit in phones, and the drives are no longer available in most laptops. Even desktop PCs lack a place to put a disk. I recently built a PC for the first time in part to digitize my media library, and I rely on an external DVD drive connected via USB. Yes, DVD, not Blu-ray. A smaller file size combined with upscaling is easier on my hard drive.

Retro nostalgia hasn’t helped Blu-ray in the same way it has aided vinyl. This is in part because most people simply don’t care all that much about video quality. Most are streaming video on Netflix and YouTube at middling settings on small screens, and many of us are acclimated to mid-range phone speakers, compared to which even the subpar built-in speakers on modern TVs sound like a huge step-up. It’s hard to convince large numbers of people to purchase an expensive version of a movie in a format that requires thousands of dollars of home media equipment to truly appreciate.

4K Ultra HD is in an even worse position

It’s been a decade, yet few people own these discs

The 4K Ultra HD Blu-ray format is an enhancement, rather than a replacement, of the Blu-ray discs that first appeared in 2006. Debuting in 2016, the 4K Ultra HD format supports the max resolution of a 4K TV.

4K TVs were still somewhat of a novelty ten years ago, but they’re cheap and commonplace today. Still, people aren’t demanding 4K-quality Blu-ray movies as a result. These discs are still less common than 1080p ones, which are themselves still outnumbered by DVDs.

This isn’t merely a matter of consumers preferring the cheaper option. Often, 4K simply isn’t a choice, or it’s one that arrives significantly later, like the Switch port of a PC title. Some recent films, like Exit 8, are slated to see a physical release over the summer yet will still be in 1080p when they do. Adoption of the newest format has been that slow.

The industry isn’t helping itself, either. 4K Ultra HD Blu-ray discs come with DRM and aren’t easy to play on a modern PC, further limiting potential growth. They do not want anyone pirating these super high-quality versions. When you consider that some of these 4K Blu-rays have an AI upscaling problem, you’re paying more for what may not even be the best version.​​​​​​​


Blu-ray is seeing fewer releases, is available in fewer places, and is less accessible in the ways many of us want to watch TV shows and movies in 2026. With our portable devices getting better and internet speeds getting faster, it’s hard to see physical video staging a turnaround, even if we’re still a long way off from it going away entirely.
