Just tested my vr headset and can confirm the same - vr apps don't work.

Hopefully Huawei will update the code for Nougat to fix this!
[Huawei P9 Questions & Answers] Timmy2k:
Thanks you! Im glad that im not alone with this problem :)

I called Huawei-Germany and they will check this today.
[Huawei P9 Questions & Answers] FlynFly:
Hello. Some apps work for me but most do not (the shaking display in VR/drifting display in 360 mode. For example Monzo, Titans of Space, Debris Defrag and few others works fine, including Google's Design Lab. However the same Google's Cardboard Demos go crazy as well as Apollo 15, Mars and You Tube. Funny but Street view starts with a malfunction, but then a window pops up suggesting do download Google VR Services (which is incompatible with my P9), so when You return to app, it works OK (stable view). Same experience? Please share, so maybe it will be easier to find a solution.
[Huawei P9 Questions & Answers] chris5s:
Yes, as above, some apps work and others don't. I have a feeling it's how the apps read data off the sensors on the phone but I'm no coding expert.

I even tried side loading Google VR Service but it didn't help...
[Huawei P9 Questions & Answers] Akinaro:
Im developing VR games for almost year, and I never encounter such problem on P9 even with latest update.

Most of problems can be related to SDK that specific apps use. Not to system it self

Sadly even with all those hype with VR, most of cardboard apps and games are made by single person devs(like me) and most of them dont update cardboard SDK of their products to be compatible with latest Android versions, because response/amount of downloads are not sufficient to push that product forward, its too much time and effort, rewarded by lack of any respond, only some random people complaining about things that actually are not realated to game/app but their device.

As far as product that use unity engine are less vulnerable for gyro-related problems, other products need way more tinkering under the hood, and its harder to keep it optimized for all available devices.

As a selfish guy that didnt spend a cent on advertising so I need to ask for every download, I would like to ask you to check my game and see if it have that problem(sadly it need controller, but you can see how gyro work anyway in main menu). Its based on Unity engine so you can check how it work with that engine.

And also I could ask you to download VR theater app that is not based on Unity and it contain latest Cardboard SDK so we can see if your problem is related to software of cardboard or its specific update of P9.

https://play.google.com/store/apps/details?id=it.couchgames.apps.cardboardcinema

Also small tip: as far as Google Cardboard app is really handy, VR services are actually not needed, and they are mostly for Daydream-compatible devices.

+ here are QRcodes for almost all VR goggles so you can scan them using Cardboard configuration assistant(that small gear in the middle of screen)

[Huawei P9 Questions & Answers] chris5s:
I've found that Unity based apps fare the worst on the P9 as far as VR goes.

Will try the above when I get back to WiFi !!
[Huawei P9 Questions & Answers] Timmy2k:
I tried all apps and still the same problem :/

I also tried different QR codes for my goggles, nothing changed.

*Titans of Space* works

I still waiting for an answer from Huawei-Germany.
[Huawei P9 Questions & Answers] chris5s:
Neither of these apps work for me.

Thanks tho :good:
[Huawei P9 Questions & Answers] lesmurf143:
:mad::mad::mad::mad:

I have this problem as well.

EVA-L19C636B361

any updates?

It seems Titans of Space works flawlessly.

You can also get Gravity Pull working if you lock-and-unlock the screen while in game.
[Huawei P9 Questions & Answers] moomoon03:
I have the same problem with my eval09c432b378??
[Huawei P9 Questions & Answers] sdeveer:
Same problem

I have the same problem and none of the other apps work.
[Huawei P9 Questions & Answers] sdeveer:
Sam problem

Could you try Cardboard design lab. That seems to work for me strangely enough. However it doesn't improve the problem though.
[Huawei P9 Questions & Answers] lesmurf143:
I tried Cardboard design lab, works flawlessly.

it's a bummer how only specific app are working/not working. The Huawei support guy I talked to is blaming the app developers.
[Huawei P9 Questions & Answers] chris5s:
Just updated to EVA-L09C432B383 and vr apps are now working flawlessly (at least, the ones i use) :good:
[Huawei P9 Questions & Answers] Timmy2k:
Via OTA?

Or do you have a link ?
[Huawei P9 Questions & Answers] Jan Philipp:
I can confirm this. No problems with EVA-L09C432B383!

Yes. I received it 3 days ago.
[Huawei P9 Questions & Answers] chris5s:
I did a forced update,but looks like it's coming via ota for some folks :good:
[Huawei P9 Questions & Answers] Timmy2k:
Thanks! It works! .

I just follow these steps for this update.

Same here VR issue was resolve with the new update, by the way I am using EVA-L19363B381 also the battery drain has been solved
[Huawei P9 Questions & Answers] EMatulac:
Go to Smart Assistance/Control System of your Huawei P9, turn off all the features. I did this. Now i can play my VR games after the Nougat update.
[Huawei P9 Questions & Answers] mitza12d:
Just scan this qr code (first one in the page below "Default Google Cardboard QR Code") and you are good to go...worked for me. I also had this fustrating problem, even with the new update (EVA-L19C432B383) but somehow this solved the issue.Hope it helps! I can't post the whole link because is my first post :)

hypergridbusiness.com/faq/vr-headset-qr-codes/
[Huawei P9 Questions & Answers] mitza12d:
Update: looks like this is a temporary solution and it's not permanent. I did a "Factory data reset" and now is solved. I didn't do it when I updated to 383 so maybe some "debris" remained from the old one (EVA-L19C432B378). So the new update will fix this problem.
[Huawei P9 Questions & Answers] barabadze:
Same problem here on p9 lite
[Huawei P9 Questions & Answers] Starfinder19:
Im on P9 EVA-L09C432B391, tried factory reset, various calibration tools but here its also only *Titans of space* that works.

Would the recommendation be to download a lower version of EVA and run that?
[Huawei P9 Questions & Answers] grombomber:
Hello Guies,

Same issue still present in 2018, i just experiment VR a short while ago.

Tried the rollback procedure from huawei, an after many bricks and days of XDA reading :), I was able to make it work with Marshmallow.

My current issue is : how to go to B383 update ?

I cannot force it, says incompatible with my previous version.

I could get from Rollback firmware => B182 => B210, but here huawei wants to update with a B386.

Any idea how to get from B210 to B383 ? (even if I have read it was a beta firmware ... not the best ... )

Which step was yours ?

(By the way I tried to install a Lineageos 14.1 and I got the same Gyroscope issues)

Thanks for the help !

J.
[Huawei P9 Questions & Answers] Akinaro:
With latest B395 everything is fine. With previous update the same.

I actually got back to helping doing some graphics and models for VR games because it finally work as it should. Tested on almost 20 VR apps and games and they all work perfectly with latest update.
[Huawei P9 Questions & Answers] grombomber:
OK then, the truth is out there ... all roms are KO for me, since I go up to Nougat gyroscope is a mess (B386, B395) ; no Factory reset or Wipe could change anything.
[Huawei P9 Questions & Answers] grombomber:
new input : uncalibrated gyroscope

Hello Guies,

i dunno if it can help / give somebody some ideas, but I have been trying many Downgrades / upgrades, all the time with the gyroscope Issue with nougat.

One important thing to notice is that there are 2 gyroscope sensors (maybe 1 is virtual), visible with the help of CPUZ application for example.

Under Marshmallow P9 ROM, "gyroscope" and "uncalibrated gyroscope" , giving the same values X Y Z at zero when still. Of course values when you move the phone.

Under Nougat P9 ROM, "uncalibrated gyroscope" displays -295 rad/s and -240 rad/s for Y and Z. That for me explains the "drift" we get in some VR apps.

Anybody understands what it is for ?

Maybe how we could tweak this ? (I have tried Xposed and a sensor module to disable the "bad" gyroscope, but nothing changed)

BR,

grombomber
[Huawei P9 Questions & Answers] Sentrey_III:
Having the same issue here, screen shaking uncontrollably when getting into a VR app. Factory reset hasn't done anything, nor did scanning any cardboard QR code.

(I'm on the huawei P9 as well, latest update as of March 2018)
[Huawei P9 Questions & Answers] grombomber:
Solved

Having tried many and many rollbacks and combination of updates, nothing worked. There is really a hardware issue with the Gyroscope.

A return to the repair service, the main board was changed and now everything is OK.
[Huawei P9 Questions & Answers] JimObrien:
I've been breaking my head trying to find SOMEONE to tell me why Cardboard won't load on Huawei Nova 2i with Nougat that Singtel mis-sold to me and as a result I can't use this beautiful phone for VR.

Eventually I got the answer from Huawei - the Nova 2i doesn't have a GYRO, and that's a REQUIREMENT to install Cardboard. Anyone found a way round this just to watch 2D cinema on Bobo headset?
[Sprint Samsung Galaxy S7 Questions & Answers] wontonie:
I was finally able to get Sprint to unlock my S7 and my husband's S7 Edge. I then had to run the 'Unlock UICC' but I was still unable to get on the T-Mobile data network. It turns out T-Mobile did not activate the data component on our accounts. After adding the APN, updating their system and two hours later, the S7 Edge connected but my S7 remains unable to connect. T-Mobile couldn't figure it out and I have a ticket open with a 72 hour window. . .

Two questions:

1) I think the error has to do with the fact that with the latest Android update, I did it after my phones were unlocked by Sprint and the T-Mobile SIM card was recognized by my S7. The reason is because this is the only difference from the S7 Edge and I keep receiving error messages about the update not being confirmed. It also keeps attempting to run the PRL update process and I don't think that applies to the T-Mobile network. Is a factory reset the only answer?

2) If I factory reset my S7, will that take away the Sprint intro and bloatware when I restart it with my T-Mobile SIM in the phone?

Thank you in advance for entertaining my newbie questions.
[Sprint Samsung Galaxy S7 Questions & Answers] lvpre:
You may have to flash tmobile or the u firmware because even though the hardware supports all the bands, the software doesn't.
[Sprint Samsung Galaxy S7 Questions & Answers] wontonie:
Thanks Ivpre! I'll try that and see where I get. I appreciate the help. :o
[Sprint Samsung Galaxy S7 Questions & Answers] lvpre:
Just remember, if you put a sprint sim card back in, it will probably relock the phone and you will have to unlock it again.
[Sprint Samsung Galaxy S7 Questions & Answers] goonygugle:
As long as it was unlocked properly it shouldn't lock not matter what sim you use , and if you put the U firmware on it you can freely switch between all carriers with no issue at all
[Sprint Samsung Galaxy S7 Questions & Answers] lvpre:
True, but some online services for this are hit and miss.
[Sprint Samsung Galaxy S7 Questions & Answers] goonygugle:
Yeah that is what I'm finding out, I have done a few unlocks over the last few days for people who lost their unlocks, I have yet to have one of mine re-lock, but certainly doesn't mean it won't happen
[OnePlus 3 Questions & Answers] Manav__25:
Hey guys suggest me,

Oxygen os 3.2.8( marshmallow) or oxygen os 4.0.3(nougat)

Thanks.
[OnePlus 3 Questions & Answers] Old_King:
You want xposed go for marshmallow otherwise go for nougat?

---------- Post added at 05:51 AM ---------- Previous post was at 05:50 AM ----------

As far as my usage of Nougat, there were no bugs and the battery life is also pretty good on nougat, go for marshmallow only if you need xposed, else go for nougat. I am using mm just for xposed.
[OnePlus 3 Questions & Answers] Manav__25:
Cool thanks I need xposed so I'll go for MM

[Nexus 6P General] vincentallen2:
So, as most of you know, Google released an update to Google Play Services that allows all phones with Nougat and Marshmallow firmware to use Google Assistant. Good!

This new feature unfortunately has to be rolled out through Google's servers. Bad

There is a simple way to force enable Google Assistant on (almost) all your devices, and all you need is root and edit your build.prop

*Please remember that these build.prop aren't necessary because Google will eventually push it your device through the rollout. However, this method just ensures that you get Google Assistant now without having to wait for that happen. So, while it may not be necessary, it can be very helpful for many marshmallow and nougat devices at this time*

Now for the "How to" part:

0. Make sure you have the latest Google Play Services, the Google app, and your device is rooted

1. Open your build.prop editor (I use J Rummy's editor) and add this single line to the bottom of your build.prop-

ro.opa.eligible_device=true

View attachment 4062532

2. Save it

3. Reboot your device

4. Wait for your device to completely boot (I waited a few minutes afterwards, just to be sure)

5. Hold your Home Button and behold this magical moment...

View attachment 4062530

*This method is very similar to what we used to Enable Google Assistant in the past. However, this method works without the need to change your device name to "Pixel" or Manufacturer to "Google" in the build.prop because Google Assistant is now updated through Google Play services to allow (almost) all devices to use it now

-So for nexus devices (6P/5X), this means you get to keep your Auto HDR Camera Mode because you didn't modify your device name or manufacturer name in build.prop.

(changing those names would have taken away those said options from the Google Camera app)

I hope this helps most of you guys out there eagerly waiting for Assistant to hit your device. It worked for me ?
[Nexus 6P General] crixley:
Can confirm worked perfectly! Thanks a ton op ?
[Nexus 6P General] vincentallen2:
No problem! I'm glad that I can finally contribute to XDA (sort of) ?
[Nexus 6P General] jassun16:
Does the Home button animation work just like it works on Pixel phones?

Edit : I updated my device to March Security update and after two days I got the assistant update without tweaking the build.prop and there is no animation for the home button :(
[Nexus 6P General] destinypham:
How can i update google play services???
[Nexus 6P General] 5.1:
Hi... You can manually update it. Download the appropriate version from apkmirror:

http://www.apkmirror.com/?s=Google+play+services&post_type=app_release&searchtype=apk
[Nexus 6P General] destinypham:
Do all of things like the guide, and even flash rom and Gapp again, but i still can not enable GA :(
[Nexus 6P General] ibsk8:
This method has been available since Assistant's release.
[Nexus 6P General] neeko92:
i see you're french too : do you know how to make it work when your phone system language is french ?

my build prop is ready to get google assistant, but when i got to google app setting, it says "google assistant not available in your country" and the google asssistant setting are greyed.

maybe there's a way to use google assistant (and google app) in english, and the rest of the phone in french ?
[Nexus 6P General] 5.1:
I don't need assistance and to be honest, I've never looked into it. :)

Maybe try to setup the assistant with English language first? And once everything works, try switching system language?

I'd try this way. Maybe open a thread in Q/A section to see if people managed to get it working with foreign system language.
[Nexus 6P General] dunjamon:
That's great, got it to update now. Will the battery take a hit of the "OK Google" recognition is left on?
[Nexus 6P General] magus7091:
I've added the line, updated play services, ran full aroma installer for gapps, still no assistant. Running Alcatel Idol 3 on lineage os 13.

Any thoughts or suggestions?
[Nexus 6P General] joshhayden10:
Updated to latest Google play services, added line to build.prop and still no assistant. Root Stock ROM 6.0.1 September security patch.
[Nexus 6P General] TokedUp:
Right after I installed the March OTA I got assistant. I didn't do anything else. I'm not rooted.
[Nexus 6P General] supermoocow5:
I just flashed the March update and re-rooted, and I have assistant now. Was going to edit the build prop, but apparently the update enables it.
[Nexus 6P General] GuestK00194:
Were you prompted to setup Google Assistant? I just updated to the March OTA manually on my 6p in hopes it would help me get Google Assistant sooner. I understand the two might not be dependent on one another but it didn't work for me. I'm using Nova launcher and when I long press the middle Circle button, it only pulls up On Tap.
[Nexus 6P General] chaco81:
No need anymore.... my 6P just got GA live just now.
[Nexus 6P General] mreediowa:
Do you need root to make the edits? I tried to edit but it won't save the file.
[Nexus 6P General] GuestK00194:
Yes.
[Nexus 6P General] dunjamon:
I had it working, but the March update has removed it again. I've updated build.prop again and it's come back.
[Nexus 6P General] chaco81:
build prop edits are not needed anymore, its already being pushed natively to all 6Ps anyways
[Nexus 6P General] wattsja:
Not mine. I loaded the stock March update yesterday and it did not work. Rooted, made the edit .. now it works.

I don't think it's ALL 6Ps ... yet
[Nexus 6P General] murso74:
I get the feeling the 7.1.2 beta won't be getting this any time soon. We're still on January
[Nexus 6P General] quickstang:
I'm on 7.1.2 beta & stock unrooted. I played with AI yesterday quite a bit. Latest play services & that's it. It just started working out of nowhere.
[Nexus 6P General] :
I wanted to provide an update. I own Google Home so I love what Google Assistant can do. This is why I've been trying to force it on my phone. Some members on XDA say they received the update after getting the March security update while others simply did nothing and received it. I was able to get Google Assistant this evening. I can't promise you'll get the update if you try these steps but it worked for me.

Earlier this week, I forced the OTA for the March security update by installing it manually. This did not help get me Google Assistant (GA). I later read in this post it needs to be enabled on Google's servers for GA to work which makes sense.

This late afternoon I enrolled in the Beta program. This updated my Android version to 7.1.2 with the January security patch level. After my phone booted up, I long pressed the Home button with no luck, Google On Tap launched.

I removed my 6P from the Beta program. I received an update to wipe my phone and to bring it back to 7.1.1. After the factory reset was complete, I restored my phone from my lastest cloud backup which was from today. I followed the setup prompts like I normally do. I noticed my Google Play Service needed to be updated. While waiting for all my other Apps to be downloaded and installed, I received an OTA to install the March security patch. I installed it right away. After the reboot, Google Play Services resumed its update. I guess it never completed because I installed the March OTA update.

I long pressed the Home button and it prompted me to setup GA. Yay! If you got the time and feel adventurous, see if these steps help you.

I'm making a few assumption here based on my experience and I could be wrong. Feel free to correct me, I'd rather people have correct information.

-Manually updating to the March SP didn't flip the switch on the Google side to enable GA.

-After a factory reset, I want to say the phone does a different type of check to see if the software version is up to date (it is different from checking it yourself by going to settings and about). I feel this way because I've been pressing the "Check for update" button like crazy this week and today with no success. I have noticed this before when I've reset my phone in the past. During the setup, there is always a check for the current version. I normally get a notification right away when a new update is available. Best regards and good luck.
[Nexus 6P General] quickstang:
I don't think there is any rhyme or reason for when you get it.

I don't think all of these steps people do either to try and get it matters either. I'm on beta 7.1.2 Jan security & did absolutely nothing & it started working last night.

Downgrading, forcing, wiping or whatever is pretty much useless. It's just a waiting game really.

Even though you got it working, you could have probably stayed on the 7.1.2 & would have received it shortly as long as you're running the correct play services.

I recommend people don't do anything & just wait. It'll happen.
[Nexus 6P General] :
You're probably right. I'm just happy I have it now. It's the only thing I've done that had any effect. To me it was worth a shot. I would rather do something than nothing.
[Nexus 6P General] joshhayden10:
Update:

Everything is exactly the same and GA finally came up. It may just take a couple of days for it to come.
[Nexus 6P General] Pig Vomit:
FINALLY just got it. Within the last hour. Stock, locked bootloader, 6P, March update, (still on) Play Services v10.2.98. I was feeling left out.
[Nexus 6P General] chudnet10:
Getting GA from a UK perspective

Hi Everyone, It appears that we have yet to receive it here in the UK, but because i am inpatient i forced the issue, i'm on the beta program 7.1.2 with the january patch with no sign of GA - updated to the latest Beta version of Google - so i changed my language settings to US, rather than UK - logged out my google account and rebooted the phone... then pressed and held the center button and hey presto GA, i then signed back into my account and it let me register and took me through everything... had it on a couple of hours and it has not vanished yet... so if you inpatient like me and want it now then give that try ;)

Cheers
[Nexus 6P General] asylumxl:
I'd do this, but I just can't accept American spellings?.
[Nexus 6P General] yudi7:
I changed all the language setting to US, cleared the Google app search data, pressed home button and finally got GA. I have now changed the language back to UK and still got the GA. Let's see for how long.
[Nexus 6P General] Dilesh Perera:
since the roll out is regional based some may not get it soon . and i found simple way by using a USA VPN . just need factory reset ( this is what i did ) removed sim card and VPN accessed by PC WIFI and after added my google account and update latest play service and google app bingo ! Assistant appeared with a greeting after few secs :)

you may try by removing google account without factory reset . i like in Sri Lanka and we dont have support for Google now cards too. but all working well now :)
[Nexus 6P General] JayDeeDaz:
I tried this, but it went back Google Now/Now on Tap after about a day :(
[Nexus 6P General] Soul_Ripper:
Well i didn't modify the build.prop file....i just updated my google play services and change the language to English (U.S) and after some time assistant was there...now whenever i change my language to regional language it disable my assistant and it comes back when i change language to English (U.S)
[Nexus 6P General] Soul_Ripper:
Change your language to English (U.S)
