I’m thinking it’s not mentioned in reviews because a lot of units don’t have these issues, or it’s not a big enough problem to bother most journalists.
I don’t see the mura effect on my 1TB OLED at all. Nor do I notice any fringing. I mean I don’t play games with my face right up against the screen, so maybe that’s why. I guess I also don’t expect a device like this to have a 100% perfect screen either, esp. at this price point. I suppose if it was made for productivity like professional graphics work it would be a serious issue. Thankfully it’s not.
The buttons are a tiny bit loose on mine, but they don’t rattle like crazy when handled normally. No sticking X or B buttons either. Nothing feels overly mushy either. In fact the D-pad is noticeably clickier than my 512GB LCD. So I think we can chalk those up to defects, or being at the far end of allowable factory tolerances?
I mean if you’re not happy with your unit you can return it to Valve. And either take another shot at getting another one to see if these things improve, or just stick to the older model until the next major revision rolls out.
Not sure if it’s the same issue, but mine makes an occasional faint electric noise (like an old hard drive being read) every once in a while. Not sure if that’s the fan or some other component. I just know my LCD model never did this. It’s not causing any performance issues or stuttering at all though.
