duo goes black

Yes. MS is aware of the issue. I had no problems getting a replacement through MS Support.

Is it a hardware issue? I thought it was software.

Hi,

Thanks for your answer.

So you're advice would be to return while I still can?

That's  pretty  much  my  symptoms  too.  Easy  to  fix,  but  yea,  annoying,  especially  since  it's  been  around  since  April  update.  Patience is  a  virtue,  but  ugh.

It happens to me very randomly. I'll be laying on my bed looking at my phone with both screens facing me in book mode and one side suddenly turns off. Sometimes there's the option to double tap the screen to turn it back on, but sometimes it just goes black for a while and turns back on a few minutes later. Sometimes, I only have one screen facing me while I'm laying on my bed and it suddenly turns off while I'm looking at it. I just turn the phone around and continue what I'm doing on the other screen, but it's still annoying. And, yes, this started happening after the update. It never happened before that. I also have the most recent update.  One time, one of the screens went black and wouldn't turn back on after many minutes. I had to restart my phone to get the screen to operate again.
