I develop a crossplatform app using Unity, with most popular device it works fine, but with new device such Oneplus2 or Honor 7 , Vuforia can't load properly the camera driver and display a black screen ...

There is any chance that Vuforia fixing this issues?

I know it is old topic, but I'm with a HUGE PROBLEM because some devides are working well and some aren't.

When I use ARCam with World center mode to First or Specific targes, it works well on all tested devices. However, when I change to Device Tracking, a lot of devices stop working and reports BLACK SCREEN.

I made a list with beta testers, as follows:

(OK) Samsung Galaxy S4 Mini - Android 4.4

(OK) Samsung Galaxy S2 - Android 4.0.4

(OK) Samsung Galaxy S4 - Android 5.0.1

(OK) Moto G4 Plus - Android 6.0.1

(OK) Samsung Galaxy S5  Android 6.0.1

(OK) LG K10 - Android 6.0

(OK) Moto G2 - Android 6.0

(Black screen) Samsung Galaxy Gran Prime Duos - Android 4.4.4

(Black screen) LG Volt TV - Android 5.0.1

(Black screen) Moto G1 - Android 4.4

(Black screen) Samsung Galaxy J5 - Android 5.1.1

(Black screen) Samsung Galaxy Gran Prime Duos - Android 5.0.2

(Black screen) Samsung A7 - Android 5.1.1

I am using Vuforia 5.5.9 and Unity 5.3.5f1 with latest Java SDK. HOW to solve this issue?

If you run the ImageTargets 5.0.5 sample app and use the "stones" target, do you see the teapot augmentation tracking on top of a black background?

in the following line the information about this issue:


I developed a simple app with Unity3d that must to recognize 8 Image target and place the same content : an interactive video where user can view different story.


I used Vuforia 5.0 SDK with a payed "Classic"  Key 

Devices that I encoutered the problem : OnePlus2 (Android 5.1.1 + Oxygen 2.1.1) , Cubot X11 (Android 5.1) , Honor 7 (Android 5.0 + EMUI 3.1)

WORKING ON  : OneplusOne (CM 12.1) ,  Nexus5 (android 6.0) and Samsung devices

the problem is that when the app start,  when Vuforia must load the camera on the AR scene the screen still black , but with the UI of my apps

in such device it still black , in other devices you see the screen splitted in 2 triangles , one black and the other with a really blurry camera ..looks like is scaled and really without focus ...


any one have the same issues?
