Anyone know if the S10 or Fold will support Linux on Dex?

I'm glad someone mentioned this, or had a question about this, since it's the one thing I would really want on a fully convertible device.

Currently the s9 and s9+ have open betas for Linux on dex, and it works on note 9 and tab s4. I am pretty optimistic that the fold will support it.

But seriously, think about how great this would be: phone that could turn into a tablet when you want (say, to read or consume media, or edit photos, or take notes). That device would also be able to run in a desktop mode for you to carry out work when you need to. The device as it currently stands does the first two, with Linux on dex you get closer to the third.

I wonder how many times you can fold the display before it makes a crease or splits in 2. Hasn't that been a long-standing problem with flexible displays? You can bend them but you can't fold them? I imagine that like paper, you can only fold it so many times before the same thing happens.

Fhat's everybody's question but given the material spec, they probably made it so no internal pressure buildup is done when folded. You can roll paper forever if you stay in the constraints

4) do the two screens wear uniformly? 5) what effect does putting a hinge in the center of the device have on the thermal capacity of the unit (thermal capacity is almost more important for performace than ram on a modern mobile computer architectures) 6) what are the long term ramifications of splitting the battery cell into two halves. It must be less capacity due to the extra packaging and safety overhead. I could…

I don’t think dividing up the battery is a big problem. You’re right that there’s some additional overhead from more packaging, but it’s not horrible. Consider Tesla batteries, which consist of thousands of cells. They are heavier and bigger than they could be (and indeed, their newer ones use somewhat fewer, larger cells for this reason) but it’s ok. Phones are more weight sensitive than cars, but a two-piece batter…

I don’t think I was totally clear. I agree if one takes a cell and cuts it in half then the overhead of managing the two cells isn’t hugely significant but I think what happened here is volume which could’ve been cell became hinge and that loss of capacity could prove to be an architectural disadvantage.

Try JS Octane benchmarks then. Or how do YOU benchmark devices? The real bottleneck is UI, not CPU's.

It isn't so much about the benchmark one uses. A CPU converts electricity to heat, and does computation as a side-effect. A CPU embedded in a laptop (or moreover, a desktop) is going to be able to convert more electricity into more heat — and more computation — by virtue of being able to better dissipate the heat due to having a larger surface area to do it over. (In addition to having active cooling — vents and fans…

Why do you think Apple is bringing iOS apps to Mac? ARM MacBook is inevitable (unless they switch to AMD).

There could be some benefits. I wouldn't be surprised if separating the battery in 2 actually helped with some of the thermal characteristics and reduced battery aging

It’s unlikely that it reduces aging. It’s probably worse but it is possible to have no impact depending on how they did it.

If IKEA can build a machine that repeatedly flexes their chairs until failure, I'm forced to believe that Samsung can build a machine that repeatedly flexes their screen. Surely that's not going to be the failure mode, it's more likely to be grit in the mechanism or fragility after dropping.

I think the parent commenter's mention of "daily use" implies things like grit. Hopefully their flexing machine also showers the phone with pocket lint.

and coins. My old v3 used to collect the odd coin while it was in my pocket. Never did it any harm. A screen might be less impressed.

This is a classic case of the technology taking precedence over the functionality. Samsung's TV division has invested billions in developing flexible displays, thinking that this would be the future. Once the technology got to the point where it was actually feasible, THEN they started thinking about how they could market it. Good product design starts by asking what the problem is and then building the solution. Sam…

This isn't being priced not marketed at the masses. This is for technophiles; people who like to be on the bleeding edge. Not everything needs to be perfected and 100% utilitarian. Sometimes people just want something because it's interesting and for now I think this falls into that category.

Also, it's basically a phablet taken to the next level. Some people will find the use in that.

You would have expected Apple to test its keyboard designs in the same way - we know how that turned out. Ironically - if that's the word - I think a larger laptop format device with a tactile folding hinged screen would be more interesting than this enormo-phone. This device will probably sell moderately in the nouveau Asian markets, but I doubt it's going to be a storming success, or the template for the next gener…

Fun story for you on that: I applied numerous time for their Failure Analysis Engineer, Reliability Engineer, and other similar positions but repeatedly got rejected (or simply ignored by their ATS, I don’t play that keyword game very well). My professional career in Materials Science and Materials Engineering has had a large focus on reliability testing and failure analysis. In parallel with inventing new technologi…

Not a very interesting story, just you complaining about how Apple passed on you with a healthy dose of sour grapes. I know a couple aerospace colleagues who got hired there though. They were well above average mechanical engineers, needless to say Apple's hiring bar is quite high.
