A weird color AR display on Oppo F9 device or more

February 12, 2020 - 9:17pm #1

I used Vuforia with Unity v. 2018.4.10f1 (64-bit) to create an AR Application on Andriod devices with Android SDK 28. After I tested with Samsung Galaxy A70(Pie version), Samsung Galaxy S10(Android Q version), ASUS Zenfone 2 and Sony Xperia Z1C (Kitkat version), it works! But after I tested with Oppo F9 (model: CPH1823) (Pie version), it appeared weird color like a first picture. Accutually should be a second picture.

After I suspected storage availability of Oppo F9 device. I cleared some data to be more than 3 GB. availability whereas my application only 25 MB. used. But, it still not work.

I tried to use video recorder feature while I was opening this app. A result is the screen was stuck but the device can track the image target correctly. It appreared a model on marker while a screen displayed same background with movable model.

I debugged the device via Unity through cable link. But, Unity console didn't has any error.

I used ADB command-line to trace back errors. It's also no error.

 

Noted: This Oppo F9 can opens camera to take photos without any problem.

 

My questions are

- What's wrong with Oppo F9 and how should I deal with it?

- What are android device limitations for AR (Unity personal with Vuforia plugin)

- Do you met this problem? if yes, could you tell me the device model names?

Hello @Fernnie,

One important clarification on the Vuforia Engine "supported" device list:

Previous to the expansion of devices that supported platform CV solutions (i.e. ARKit, ARCore), devices had to be hand calibrated by Vuforia Engine to support Advanced Engine Features, such as Model Targets, Ground Plane and Extended Tracking. Thus, in the recent past, there were devices that were considered "supported" (e.g. hand calibrated by Vuforia), and "unsupported" (no calibration, and no ARKit/ARCore support).

With the recent expansion of devices that support ARKit and ARCore, we will no longer specify devices as being supported. Thus, our article will be renamed to "recommended" devices in the near future. This list will represent devices that Vuforia Engine believes will provide the best possible performance when running our features. However, it is not a complete list as other devices that are not listed will likely also work well with Vuforia Engine.

The list is mostly to there to provide guidance to our customers when making device purchase decisions. I hope this helps.

Thanks,

Vuforia Engine Support

Hi Fernnie,

Thank you for the provided data. In the logcat dump I found some access denied logs when Vuforia is initialized. At this point in time I am not able to determine if this is the culprit and also don't have an Oppo F9 to reproduce the issue.

Could you please try also our Core Samples app from Unity and confirm that you see the same issue?

Thank you.

Hi

So sorry to say I didn't use this command but this, $ adb logcat *:S. A dump log stores at https://drive.google.com/file/d/1lQY9WtG2tIFeZlt_HEPYTyAK3RoucQ-O/view?usp=sharing 

Moreover, there is no any information, warning or error log noticing on Unity Console. Let's see https://drive.google.com/file/d/1U2NGlUx1jv0xdi5aFTmrRCosLZvG988C/view?usp=sharing

Please stay focus on "-----------Manual comment: " to track what event I've done.

It seem likes a suspected problem occurs at yellow highlighted, not sure. Please use these data for further amenity.

 

Sincerely,

Similarly to me, I'm not found you phone model name in the list. It means this phone is not guaranteed. I can't do anything. If you accomplish, please let me know.

Hi,

It sounds bad to hear a ton of phone is unguaranteed. But, I found my phone, Sony Xperia Z1 Compact, worked correctly albeit out of your list. However, thank you very much for your confirmation which are supported or unsupported.

Sincerely.

Hi,

Usually ARCore supported devices are supported also by Vuforia. However we do not certify each ARCore device, this means that there is a high change that the ARCore supported device will also work with Vuforia.

Below a list of devices supported by Vuforia and ARCore.

https://library.vuforia.com/articles/Solution/vuforia-fusion-supported-devices.html

https://developers.google.com/ar/discover/supported-devices

In addition please note that Vuforia at core recognizes and tracks, the rendering is done by Unity.

Thank you.
