    Vuforia positional tracking works fine even on very old devices (galaxy note 2). But I encountered problem with newer devices such as Pocophone F1 and Nokia 7+. Vuforia does not activate positional tracking on it, and on many other very capable devices.

    Is there any reason for it not working? Is there a list of devices supporting positional tracking? How can I debug culprit of positional tracking initialization failure?

    TrackerManager.Instance.InitTracker<PositionalDeviceTracker>() just return null without additional info.

    Hello,

    Not all devices support Positional Device Tracking. What's not supported by ARCore, Vuforia has made its best attempt to fill in the gaps with Vuforia VIO:

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

    Strange that Vuforia returns null, so I wonder if something else is going on. How does the Pocophone F1 run with out public samples? Can you send the adb logs from that device running our samples?

    Thanks,
    Vuforia Engine Support

    Thank you for response. I checked default Unity Core Samples and got the same result. Neither Pocophone f1 nor Nokia 7+ is able to start ground plane tracking, VuforiaRuntimeUtilities.GetActiveFusionProvider() return VISION_ONLY.

    I was mistaken that tracker is null because I checked it too early. TrackerManager.Instance.GetTracker<PositionalDeviceTracker>() returns PositionalDeviceTrackerImpl but it still not using fusion mode I assume.

    Here is logcat result for Pocophone f1:

    Hello @dnnkeeper,

    Thanks for the data. I have no explanation for what's going on. Best I can do at this time is to procure the device and give it a test.

    I'll update this thread with updates when available. Feel free to ping me.

    Thanks,
    Vuforia Engine Support

    I managed to run Pocophone f1 with Vuforia and newer ARCore library but it still doesn't work properly despite on Platform_Sensor_Fusion provider status: Ground Plane finder not able to find any plane in sample project. And in my project as soon as I move camera away from the image target, virtual scene rotates and disappears so I can assume positional/rotational tracking messed up too.
    I'll be glad to debug such issues so if you need any info, I can use my devices to run tests and report back. Device coverage is very important now so I need to decide either use arcore library with it strict list of supported devices or use Vuforia to extend its variety.

    Hello @dnnkeeper,

    The device should arrive this week. I'll do some testing with it once it arrives.

    Thanks,

    Hello @dnnkeeper,

    Device arrived and I was able to replicate the ARCore issue when running Vuforia. We are tracking similar failures on other devices that use the Snapdragon chipsets (LG V30, V35, V40 and G7). With those devices, we were forced to set the ARCore camera capture resolution to 640x480.

    I'll need to do some additional investigation to see if a similar workaround is required.

    Thanks,
    Vuforia Engine Support

    I'm also having the same issue on my project. I went out to get the Pocophone F1 as one of the cheapest devices that can run ARCore, but was disappointed when my app using vuforia didn't work with it.

    Same issue with Pocophone F1 and Samsung S7 - can anyone outline the workaround steps needed to set the camera resolution?

    Hello @ThatMunk,

    Still working on the Pocophone F1.

    What is the problem with the S7? What is the model number? To find an Android device's model number: Settings->About phone/device->Model number

    Thanks,
    Vuforia Engine Support

    Hi @meedabit

    Samsung S7 SM-G930F - it appears to have the same tracking issues as the Pocophone F1.
    I havn't logcat'ed neither the S7 or the F1, but I can reflect the description by dnnKeeper.

    Hello @ThatMunk,

    I see where Vuforia Fusion's ARCore support has been disabled due to performance issues. However, the device is Vuforia calibrated so I would expect Advanced Features, such as Ground Plane, to work.

    Still not clear what issue I'm responding to for the S7. Is it that the feature does not work on that device? Or that you want to change the camera resolution?

    Thanks,

    Hi @meedabit

    Is Vuforia Fusion's ARCore enabled for pocophone F1? Please guide us on using ground plane feature, we would love to use the same for our projects.

    Any workaround would be appreciated.

    Thanks,
    Bharad

    I too have an issue with Samsung S7 where the TrackableBehaviour Status will constantly change between LIMITED, TRACKED and NO_POSE. I would expect status to at least remain at LIMITED (rotational tracking).

    Vuforia Fusion Provider=VUFORIA_SENSOR_FUSION

    @meedabit Here's a video which shows some very weird feedback for extended positional tracking on an image target, if it helps:

    This is on Pocophone F1 - works absolutely fine on Samsung S8


    EDIT:
    Also seen using depth masks - this bug may be irrellevant to the tracking issues?

    I'm having the same issue on a Galaxy tab 4, PLATFORM_SENOR_FUSION is being used but when I move the camera the content of the markers follows and doesn't stay anchored.

    Hello @Nassiem,

    If PLATFORM_SENSOR_FUSION is being used for Galaxy Tab S4, then that means ARCore is providing the tracking, not Vuforia. Thus, the performance issue you're observing is related to ARCore performance on that device.

    Suggest you search for additional information about ARCore performance on that device.

    Thanks,
