Ground Plane not Functioning in Samsung Galaxy S21

September 9, 2021 - 2:09pm #1

Hello, 

Just curious if anyone has had issues with getting ground plane tracking to function on their Galaxy S21 device. The ground plane is detected when using the webcam. Just when I build it out to the device nothing, not even the ground plane image is detected. I had an older device a Galaxy S8 and functioned perfectly fine on that device. 

 

Device OS: Android 11

Unity Version: 2019.4.12f1

Vuforia Version: 8.1.12

Hi Patrick, 

 

Initially I also ran into a black screen issue. I ran into this issue with another version of Vuforia before and resolved that by unchecking "Include ARCore Library" in Vuforia Configuration. Once I unchecked that, the black screen disappeared but still no ground plane tracking. Afterwards I found the other thread where you suggested a 64-bits build and that resolved everything. 

Camera is focusing fine now. 

Thank you

Hey,

 

Good to hear that you fixed it. Can you confirm that you did not see a black screen, but the ground plane was not tracking? Or was there also a black screen? 

I recommend checking out the camera article where you can find a sample to set the camera to continuously auto focus.

Hi Patrick, 

 

I managed to get it working actually. I saw the solution you posted for fixing the black screen issue, for the S21+ and once I changed my build settings to build for 64-bits everything worked fine.  Although the camera is quite blurry and its focusing is non-existent. 

 

thank you!

Hello Patrick, 

 

I had to download a newer version of Unity in order to use a Vuforia version 10.x. Unfortunately the ground plane is still not functioning. The Samsung Galaxy S21 is listed as a supported device.

Hey there,

 

I would advise to upgrade to 10.x to see if that resolves the issue.

If not, let me know!
