I'm starting to worry that my RMA replacement Deck may be defective...
One weird quirk that this one has is that it makes a metallic clinking noise when I press some of the buttons or tap it in certain places. Slightly annoying, but that's not my concern.
My concern is that the majority of the time when I wake it from sleep, the physical controls do nothing. So I have to use the touch screen to enter my PIN, which isn't a huge deal, and then use it to navigate the menus, which is a big deal because a bunch of the UI elements really aren't designed for touch. Eventually, I'll get to the controller calibration page, and everything starts working again.
I'm running SteamOS beta, but I did that with my original Deck and never had this issue to this extent. It prevents my new Deck from being a device that I can turn on and immediately use. I'm starting to miss my original one.
Please don't tell me there's another RMA in my future...
EDIT: Trying to revert to the stable build seems to have soft-bricked it. Whenever I turn it on, it gets to the little splash screen, and then it gets stuck on the Steam logo with a swirling effect around it. Guess I'll have to re-image it.
I wonder if I just got extremely lucky, and my original Deck just happened to be a golden sample (that died unfortunately). This one is having lots of little issues that my previous one didn't.
