Not working on Samsung S8+ (SM-G9550)

[m0o0scar]

About the phone

• Device: Samsung S8+
• Model number: SM-G9550
• Android version: 7.0
• Build number: NRD90M.G9550ZCU1AQH6

About the problem

What happened?

1. Successfully build and deploy the Hello ARCore Unity example scene following these guides: Getting Started with Unity | ARCore and ARCore for all - Unity Installation;
2. Hello ARCore app runs on the phone;
3. "Made with Unity" splash screen is shown;
4. The app crash.
5. Restart or reinstall the app won't solve.

What's in the log?

These are what I saw in the logcat during the app crash:

So is there a plan or ETA for supporting S8+? Or we have to wait for further release of ARCore from Google?

[tomthecarrot]

It works on my S8+ and IIRC other people have confirmed it working on S8+. However, some S8+ devices do not work. We have an experiment that IMO is getting close to making ARCore run on most devices, albeit without accurate calibration at first. Please feel free to jump into the branch referenced in the README and help us!

I can also confirm it works on my S8+. I found the app crashed when I didn't follow Google's Unity setup instructions to the letter. (For instance, you have to turn off multithreaded rendering in Unity.)

[m0o0scar]

@pennomi I did follow Google's instruction when setting up the unity project. I'll try the branch then :blush:

[detomato]

It works on my S8+(South East Asia) too.

Unlucky, my S8+(NRD90M.G9550ZCU1AQH6) does not work.It was stoped at screen with "Searching for surfaces ..."

S8+ G9550ZCU1AQF7 dose not work.

[tschussler]

I have successfully deployed using a Samsung SM-G955U1 model S8+ (unlocked model)

It's important that you remember to include the correct modified unitygar.aar file and remove the original one! Don't just rename it.

[solidcinu]

tschussler could You please explain me step by step what do You mean by that please??:)

[detomato]

I have 2 S8+, works on one, but not the other. Guessed its depends on your luck.

[m0o0scar]

@detomato Any difference on system version and other stuffs?
