Not available on Samsung S9 Plus

[p-sik]

I can't install the app on my S9 Plus, even though it should be compatible? It doesn't find it on GPlay or says the device is not compatible if I go through the Play website. Do I have to wait for an OS update before I can use it? All the news said it is going to be supported on it at launch?
Device: S9Plus SM-G965F

Same on S9 - SM-G960F

[inio]

Support for the S9 and S9+ will be added soon.

[jmeyers44]

@inio can you confirm that s9 support was not part of v1.1.0 release?

[inio]

@jmeyers44 We encountered a driver issue that has delayed S9 support.

[jmeyers44]

thanks for the update @inio and appreciate all your guys hard work!

[Envenger]

Any estimate on when the support for s9+ will be enabled?

[inio]

@Envenger: We're waiting for an Android update for this device (fixing the driver issue) before we can support this device.

[mweinbach]

Is there an ETA from Samsung on when this update will be released? Also this is a Qualcomm driver error that is also in the Camera app and a couple other apps.

Here is the corresponding thread in the Samsung Forum:
https://us.community.samsung.com/t5/Galaxy-S9-Questions-and-Answers/ARCore-support-on-Galaxy-S9/m-p/310706/

[inio]

@mweinbach The issue relates to the behavior of the camera when image readers of different aspect ratios are attached to a capture session. ARCore uses a 16:9 1080p SurfaceTexture for display and a 4:3 480p ImageReader that needs to be full-sensor for motion tracking. On the S9 right now the 4:3 frame is getting cropped out of the 16:9 crop of the 4:3 sensor. Effectively it's the opposite of SD video that's pillarboxed into a 16:9 frame and then letterboxed back to a 4:3 frame. As a result (even with proper calibration) the motion tracking performance is unacceptable.

[p-sik]

And on which side must the fix get in? Is Samsung working on it or are you just waiting for something to change before implementing it and hoping that something will change in a future update for the device? Will it ever be compatible (as in this year or so)?

[inio]

@smr4d I believe a fix is in the works on the Samsung side.

[Envenger]

@inio I am a developer working on an ARCore project.

I only have an s9 with me. Is there any way in which I can test the application on s9 even with lower performance?
I have problem with using emulations.

[inio]

@Envenger Your best hope is to try the 1.1 APK on our releases page. If it contains a calibration for the S9 (I suspect it does), it's for firmware without the driver bug - we wouldn't bother calibrating a device with the crop+crop issue. It'll either work perfectly (if your specific firmware doesn't have the driver bug) or never start tracking (if your firmware does have the bug).

[Envenger]

@inio
Thanks, it actually worked.
The detected planes do not line up with the camera but it works.

I have the project deadline in a week and this saved me.

[Inspyro]

So Samsung just responded, it should come with next months security update

[logixworx]

Will ARCore on S9 utilize the new 6DOF SLAM hardware on the Snapdragon 845 models?

[inio]

@logixworx I don't think that article is talking about any new sensors. The "Adreno 630 visual processing system" is just the GPU.

[Maseycx]

@inio Why was the fixed in upcoming release tag removed?

[JP-Dorman]

The security update just came through on my device - can this issue be resolved now?

[Inspyro]

It's not clear so far if Samsung fixed the issue in this security update. They said it is probable that it will come in next months (May) security update

[porunov]

Will S9 devices with Exynos processor support ARCore?

[inio]

@Maseycx To avoid confusion between the meanings of "upcoming" and "next".

@JP-Dorman @Inspyro We're investigating if this update has resolved the issue.

[inio]

@porunov I believe we will start supporting all S9 devices that ship with the Play Store at the same time.

[lastchance008]

China(Hong Kong) version SM-G9650 is not even listed in https://developers.google.com/ar/discover/supported-devices, is there any hardware difference?

[Guoxyang]

Will the SM-G9650 be supported in the future？

[hectorC]

Today I was able to install ARCore from the Play Store and all AR apps so far have been working on my S9. This is without receiving any system updates from Samsung (unless something was done in the background without user intervention)

[inio]

So this caught me by surprise: 1.2 includes a fix on our end to work around the camera driver issue. The S9 and S9+ are now supported.

My understanding is that one side effect of the workaround is that some apps that use the camera texture in unique ways may behave a little oddly on this device. Apps using transformDisplayUvCoords will work correctly, but apps that make assumptions about the display aspect ratio of the texture will have a squished image because the texture is now full-sensor (4:3) instead of a 16:9 crop.

[flankechen]

not available with sm-G9600/DS, which should be ok, it has a 845 soc

[manacrox]

Still not working on SM-G9650!

[inio]

@manacrox At this time, ARCore is not generally supported on Samsung devices with model numbers ending in 0 or 8.

Exception: Hong Kong versions of the the S8(+) and S9(+) may be used for development only by side-loading ARCore APK from our releases page.

[JMLX42]

Working perfectly on SM-G960F
Thanks!

[manacrox]

Now working on SM-G9650 with latest Samsung's update!
It did work (not accurate at all), but only a few times.

[alexboyer]

This is still happening on SM-G965U
Started working after a software update from Samsung today, 2018-06-28.

I have the same situation. ARcore can be downloaded and used for a while, but soon I can't detect the surface.What is the reason?

[iamakg]

It works perfectly fine on S9 but won't find floor on S9+.

[inio]

@iamakg Keep an eye on #419. Is it possible you have retina unlock enabled on the S9+?
