Camera Black Screen on Android 11

SDK 10.0

Topic solved

I get black screen on my phone's camera every time I build for Android 11 even though I had accepted the permission to access the camera. The build was fine

for Android version 10 and below. So, is this a bug for Android 11 or I just missed something here?

Thank you for the help.

Hi, 

Couldn't figure out how to make my own post so I reply here since I'm having the same issue.

I'm developing an app on Unity 2020.3.16f1 for a couple of weeks now, everything worked perfectly.

Suddenly, I made a new build, and got a black screen. 

I tried using old builds that 100% worked before, still black screen.

I tried using GroundPlane sample scene on this specific project, didn't help.

Tried chaning to IL2CPP, didn't help.

Tried updating my phone (Galaxy S21 Ultra), tried updating Vuforia (was using 10.1.4, upgraded to 10.2.5), both didn't help.

 

What am I missing?

I got my own scene finally working installing the core sample. Sorry for the late reply

Hi there

I was facing the issue (as I made a thread, just look down a few posts and you'll see mine)

But I managed to fix it, mention my answer, and maybe suggest creating it as a sticky if it's an easy universal fix?

I was just curious what  Dario meant by it working with Vuforia's core sample, and if it meant he got his own scene working also (like mine)

Hey Cozzie,

 

Are you also having a black screen on Android 11? Just trying to see if this issue is reappearing.

What do you mean downloading core samples fixed it?

Do the samples work? How about your own project?

I had the same problem but downloading the core samples solved it.

Unity 2020.3.17f1, Vuforia Engine 10.1 and Samsung S10+

Hey there,

 

Don't worry about your English, we'll manage! Can you provide me the following information:

  • Unity version
  • Vuforia Engine version
  • Android Device Model

Would you be able to download the core samples and build that to your device to see if the issue persists?

 

Kind regards,
