Samsung disables 3rd party DeX support in Galaxy S8's fourth Android Oreo beta


The Samsung Galaxy S8/S8+ received their fourth Android 8.0 Oreo beta update yesterday, and unfortunately that comes with a downside. Samsung has decided to block the use of 3rd party DeX docks with their phones.

Samsung DeX is a powerful feature that allows Galaxy S8/S8+ owners to plug their phones into a dock and get a desktop experience by connecting the dock to a monitor. While Samsung's proprietary dock costs upwards of $150, some clever users have found workarounds for this. One XDA Developer user was able to turn their MacBook into a DeX dock, utilising the phone's processing power and the Mac's display, trackpad, and keyboard. Upon updating to the newest beta however, such users found that their DIY docks would only mirror their phone's display rather than giving the full DeX desktop experience. This change, if kept, is sure to disappoint users who were looking for a cheaper way to make use of one of their phone's most interesting and unique features. 

Huawei recently unveiled the Mate 10, and one of its newest features was to include the ability to use the phone to power a desktop experience. While this is very similar to what Samsung did with DeX, Huawei was able to do it with a single USB 3.1 Type-C cable rather than a bulky, expensive dock. Sure, Samsung's DeX dock has its advantages like being able to charge the phone at the same time and being able to use gigabit ethernet, but with such a simpler alternative on the market, it is a little disappointing that Samsung is going to such lengths to sell more of their expensive docks.

What do you think about this news? Is Samsung becoming too restrictive with their phones nowadays, or was this a smart move for them to make? Let us know what you think in the comments.

If it's taxing on the phone it would make sense to limit 3rd party peripherals to control further stress on the devices. From the sound of it, doesn't dex dock even come with active cooling fan?

Still can't beat Continuum feature for feature. The only advantage DeX has is multiple Windows which is not a pleasurable experience as the phone generates substantial heat. When I had it with an S8+ it became a hulking throttled mess. The HP x3 and Acer Primo docks both have Gigabit internet and all UWP apps run in Continuum. This is one area where Microsoft is clearly ahead in the app department.

O dont think Dex was meant to compete with Continuum. Also the phone itself both the S8's and Note 8 have gigabit modems. So far even apps not specifically designed for Sex, work, even in full screen. No platform is EVER gonna offer what Windows does, but Android is the only one that comes close. I don't see the problem . If you want or need Continuum, that person can always. It a supporting device. Right?

Dex dock is great, not bulky, looks great on a desk. Has a powerful yet quiet fan. I rather have a Dex Dock then to plug my phone directly into a monitor. And they aren't as expensive as they seem. Sales, 2nd hands, they are cheaper than they were. If you're a person who actually would do work like Word and power point it works well.

Have you even used any of those k kickoff docks? Because I have. Many have no cooling, don't upscale to 4K and more Try using a knockoff and you will see why this was a great move.

I paid $75USD for. Dex on eBay. I'm glad they made 3rd party ones not work, because they don't give the same experience I ordered a knockoff from China and it didn't upscale to 4K, it was also slower, compared to the real Dex. The one I had also didn't have a cooler, so when the phone got to warm, the phone would shut the workstation down.
