Hi,

I wonder if someone has got some ideas for a solution.

I created an AR app that works as intended on mobiles (Galaxy A7, A6, Samsung S22, 23, One Plus 10T Pro…).

I need it to work on an older tablet Galaxy Tab A. The camera doesn’t start at all. I can see the UI I created and a blank screen.

What I have done so far:

  • unticked Multithread Rendering
  • set minimum API level to 8.0
  • updated Android on Galaxy Tab A to Android 10
  • Cemara and app permissions are granted
  • I have used Vuforia for image targets
  • I added Google AR core
  • I opened the Unity project with an older version of Unity
  • I tried troubleshooting in Android Studio but I dodn’t know it well. The message that is related to the camera says: Camera2-Fr…cessorBase cameraserver FrameProcessorBase: Error waiting for new frames: Connection timed out (-110)

What is interesting is that last year I created a similar app that worked on Galaxy Tab A. Actually, it still works - the camera starts etc.

Thanks

Galaxy Tab A does not support ARCore: ARCore destekli cihazlar  |  Google for Developers

Looks like Galaxy Tab A7 would be the minimum supported device in the Galaxy Tab category.

Thank you!
The strange thing is that when over a year ago I created another AR experience the camera worked. Has the support ended on these devices?

Hmm… Try to Disable Internet and Delete updates for Google Play Services for AR in
Settings > Apps > Google Play Services for AR > 3 points in top-right corner > uninstall updates.

If it works, then this is a temporary solution for testing app without the internet.

That’s a question for Google. What I can tell you is that if your device is not on the supported devices list, you should not expect ARCore to work.
