has anyone used this to connect via bluetooth? i am looking to connect an android smartphone and a surface pro 3.

It's not bluetooth but In the case of the Surface Pro 3 you can connect the usb transceiver of the keyboard to the usb port of the surface (if you don't have space in the port you can buy an usb hub to connect multiple usb divices including the usb tranceiver of the keyboard). In the case of an Android smartphone also you can use it but you need to buy an OTG cable (https://www.amazon.com/dp/B00LN3LQKQ/ref=cm_sw_r_cp_apa_aV3rxbAXHV1FH) and connect the tranceicer to the android device, it would work (I proved in Galaxy Alpha, S6, Tab S2, Motorolas and works perfect)

Has the build quality improved? The original K400 left a lot to be desired in this area (letters rubbing off, mushy keys, creaky flexing body).

Just arrived and used it for 2 days. Met my expectations as a couch keyboard. The trackpad works well and the left-mouse-button key at the top left is rather handy. Build quality is fine given its price, but definitely inferior to the K480 and K800 that I have. Haven't used the original K400, but haven't seen yet (it's been 2 days only) the old problem of letters rubbing off. Keyboard body is reasonably solid. Don't expect this to be your day-to-day working keyboard -- the keys are too soft for a good typing experience.

Has anyone used this with a Steam link device? Any issues?

I just got this today specifically to try on steam link. Yes, it does work and at a surprising distance. Track pad and keyboard working. So for steam link users :) this keyboard does work.

Will this work with a Samsung un40eh5300fxza that appears to be running under Linux?

Yes it works with several versions of Linux that I have on several computers. Just plug & play on my machines. You won't get keyboard customizations provided with Logitech software though. Linux recognizes it as an ordinary keyboard on my machines. I guess you can check if the company's website has Linux software for customization settings, but I didn't bother because it works. I use these for computers connected to home entertainment centers, not for my primary computers. So they don't get typed on much because they're used mostly to navigate & use media. Nonetheless, the letters on several keys rubbed off after just a couple moths of very light use. A year later almost half the keys don't have letters on them anymore. I never had letters rub off keyboards before, & I've used dozens of them. I'm typing this on a HP keyboard (my favorite) built in 1999. None of the letters are wore off after extremely heavy usage for almost 2 decades.
