UE4 4.11.2 Gear VR Crash

Hi dude,i am gear vr developer with ue4,when i packaging gear vr app with 4.11.2,this app can run with sunsume s6 and s6edge,but run crash for s7.i think this crash is ue4 4.11.2 bug.

Hi -

Can you get the logs from the device for the crash and post that information here for me?

On your Device you’ll need to be able to access the Samsungs File directory for the device.

Navigate to Device Storage\UE4Game\ProjectName\ProjectName\Saved\Logs.

Copy this and upload here.

The next thing is to have the crash happen while trying to load. For this you’ll need to have the S7 connected to your PC and set to Developer Mode for the Gear VR service. This will prevent the need for the GearVR Headset and allow you to see both eyes from the GearVR Project that is loading on your device screen.

  • Navigated to C:\NVPack\android-sdk-windows\tools
  • Run the Monitor.bat file (this will open the program Android Device Monitor that can capture the logs)
  • In the Saved Filters on the side, set one up for UE4 that looks like this.

  • Now in the Preferences set the following

  • Now you simply need to run your game and the logs will be printed out in the window below. Copy these after the game has crashed and paste to a text file you can attach here.

Thank you!

Tim

Hi Tim,Thank u reply.this is my game log link text

i thank this is crash app reason — Orientation wasn’t applied to a camera in frame

Can you also provide the log from the device, not the one using Android Monitor, but from the game folder?

Are you able to reproduce the crash in a blank project at all when launching to the device? If so, include those detailed repro steps here. If not, are you abel to provide your project or a project that causes this same crash?

If you launch your game on the device, but disable the GearVR flag in the Project Setting > Android do you still get the crash?

Annie Amber developer here.

Our game also experience crashes in the s7… and sales lowered dramatically in the store because of 0 stars user reviews. We don’t have and s7 yet (on its way since 3 weeks…) but some users that experienced the crashes agreed to help us. So far, this is what I found.

Making an empty level and copypasting the level assets and re-doing the level blueprint solved it for one level… but didn’t solve it for other 2…

It is not precomputed visibility releated. Sorry but this is so far what I found. Game works great in other GearVR devices.

Yes,i will go to try.i find a bug for ue4.if i not add Text Render Component the app can run.but i add Text Render Component,the app will crash.do u have a solve method?

Hi Tim,thank u reply,i find a Bug ,if i add Text Render Component for first character, my app will crash in s7.

Can someone here in this post provide a sample project that crashes consistently for them when used with the GearVR?

Also post the device specs for the phone such as:

  • GPU Set,
  • CPU set
  • Current OS version

Thank you!

Hi Tim,my project upload to github always fail.can u tell me u email?

You can message me a link here: https://forums.unrealengine.com/private.php?do=newpm&u=4894

Hi There!

We have here the same problem.
We are developers of Dark Days, next Vr title on Gear VR and our game crash (in game) only on S7.

Have you finally find a solution on your side?

thanks,

Can you include the information listed above, such as the logcat, project logs, repro steps to get the crash, and a sample project if possible that can reproduce the issue?

Without this information, at the very least, logs and repro steps I can’t know where to even start to look into the crash and see if I can reproduce on my end.

Also make sure to include the devices that you’ve tested on with their full specs, and whether disabling GearVR and packaging the game for your device produces the crash as well.

Thank you!

Hi Tim! Thanks for your reactivity!

I’ve joined here a log of the crash in a zip file.
For the project, I can give you an access to our perforce if you want!

Thanks again,

The S7 phone model where it crash:

SAMSUNG-SM-G935A
Android version: 6.0.1
BaseBand version: G935AUCU1APB5
Kernel version: 3.18.20-7193387 dpi@SWHE2608 #1 Tue Feb 23

The S7 phone where it works well:
SM-G935W8

Is this happening only on an S7. We do have some S7’s to test on but they are on custom firmware and are not close to the public released version. If the crash happens on anything else it would be helpful to know because we do have a variety of other stock devices to test with that may be more helpful initially.

Yes, It occurs only on S7 (normal & Edge) the model: SM-G935A.

Not sure if it’s related but putting it out there in case - we also had S7 crashes with the Snapdragon chipset when using fresnel materials on an instanced static mesh: [Gear VR] Instanced static meshes with a material containing fresnel causes a crash on S7 Snapdragon devices - Asset Creation - Unreal Engine Forums
Maybe you have that combination as well?

It seems it could be something like that but we didn’t have this node in the game (Fresnel). Do you think another node could cause this issue?
