Hi there,
I have a (stock) Cubot One S and recently purchased a Cardboard kit.
Anyway, I can install and launch any Cardboard app and can always see the on-screen centre divider, the settings (cog) icon at the bottom and when I launch the Cardboard app I can see the 'intro' icons and tutorial. The issue I am having is that I only ever see random vertical lines in both sides of the split-screen instead of what I should be seeing once an app starts, including the Cardboard demo apps.
I already knew the magnet would not work as this phone does not have a magnetometer; I confirmed this by installing a compass app that reported no hardware support was found on the device. This wasn't a big issue; I can always just pop the flap open and tap the screen. I at least expected the video to work, though!
Is anyone else having this issue with a Cubot brand phone? Any help would be much appreciated.
A small update...
I have downloaded one game so far that works: Highway Stunt. No other cardboard games nor apps work; they all exhibit the same display problem mentioned earlier. I have a feeling it's either related to the GPU reporting incorrect values or the firmware incorrectly reporting the graphics capabilities of the phone. It's frustrating either way.
I'll post the solution if I find it.
I recently bought a cardboard. But cant taste many apps because my Android smartphone doesn't have a Gyroscope sensor. So i searched for an app that can mimic the gyroscope functionality by pressing keys or something.
I got these...
1. https://github.com/memsindustrygroup/Open-Source-Sensor-Fusion/wiki/Virtual Gyro
2. http://www.mcubemems.com/products/igyro/
These aren't any app, but proof that Virtual Gyroscope exists. Some lenoveo phones(Like K3 note) use them. So plz let me know, is there any app that can do the same effect in any android device with Accelerometer & Compass sensor. Or, any app that can mimic the effect pressing volume/headphone key.
only look left/right action is required , Accelerometer does look up/down.
Yes by this i wont get a head tracking experience, but at least I can look around and select files to watch videos. Developers can make app(if doesn't exist already) following this idea. I think, it will help many.
Thanks in advance
Hi, I'm also looking for some app that fakes gyro sensor as I have the same problem. In theory a dev could interpret those algorithms from that Github repo and make an emulator, unfortunately this is out of my knowledge.
So I hope someone could help us poor ungyroscoped people.
Yeah, it's big problem with most phones to use VR apps/games that require gyroscope. I have the same problem.
Google should think about gyro pseudo emulation with accelerometers in their Cardboard API or at least implement there something like this lib: https://code.google.com/p/openintents/wiki/SensorSimulator
so anyone could use different phone (with gyro) as remote gyro for phone in cardboard glasses or write gyro emulators much more easily (as this lib can open TCP port for remote sensors data).
Technically, yes, it should be possible, using Xposed.
I am working on a module that eliminate the jitter in unreliable phone's gyroscopes. It does so by hooking to the function that distpaches the various sensors' data to every apps that require them, and it fakes the values before these data get sent.
Since you can easily access any sensor's data, you can do any sensor fusion you want by using the accelerometer and magnetometer, or even just the touch screen, and then fake the gyroscope's values.
If you are interested, here is the Xposed module I'm working on, which shows how to hook to the gyroscope and fake the values:
On github: lrq3000/JitteryGyroFixForCardboard
And to implement sensor fusion, you can either use the new virtual sensors of Android 4, or code it yourself, there's a very good open source app that shows it all here:
On github: KEOpenSource/GyroscopeExplorer
Hey thank you for that info! I'll be taking a look at that as soon as I can, although I'm not an avid dev I hope we can get something for our phones.

Yes, same problem here. The facts, med-low or med or med-high device not attached by gyro, except xiaomi. Some people on quorra debated, they have idea to make an app which can do headtracking with camera by detecting pixel shift. Yes i like that idea and the idea sounds possible, but it out of my knowledge. Can anyone make app like that? Or maybe we can ask google to make the app?
Thanks
What about emulating gyro using accelerometer and compass? In the Google Play is app for phones without gyroscope, (we are in space: LINK) so it is possible
I would love to see something like this too. This dev has several VR apps and the head tracking all works perfectly on my Moto G 3rd gen which has no Gyro, so I know it is possible. I've played House of Terror and the head tracking works extremely well and pretty smooth too, I wonder what their method is, I assume compass + accelerometer. https://play.google.com/store/apps/developer?id=Lakento

Same problem. I also have a k3 note and it has a virtual gyro. i think there must be something that uses accelateometer and magnetometer to detect direction and angle.(and i think this is possible)
Guys try vr player from play store then goto settings and there would be orientation detector set it to accelerometer +compass and you are donw
Same Problem

I bought a vr case and have the same problem my galaxy sm a510m (A5 2016) doesnt have gyro! When i saw that i couldnt believe it.... it opens with my fingerprint for the love of crist!!! :crying:
Any solutions?
I have a moto g 3 and can't experience Pokemon go neither vr visor from one plus
Sent from my MotoG3 using XDA-Developers mobile app
Is there still hope?
If there is no way (for whatever reason) to emulate a gyro...is there a method to add a gyroscope sensor to an android?
Sent from a Samsung Galaxy J7 user
Same here, i too need an APP that simulate the gyro functions.
Hope that someone could implement that using compass and accelerometer!
Thanks
Some app like this would be so cool...
I was a bit dissapointed after buying the Moto X Play and noticing it doesn't have gyroscope so no Augmented Reality on Pokemon GO.
Im so sad, i had a moto g2 and bought motog3 1 month ago, this thing doesnt have a gyroscope while motog2 had one. Is there no solution for this? I mean, with something like a virtual gyroscope

I've tested with my Moto G 3rd and works well. I hope somebody develop some hook in Xposed to work with accelerometer and compass...
or lests just hope the pokemon go app support accelerometer + compass it in the future.
I feel where you all are coming from. I agree there needs to be an app, an xposed module, or something to get this functionality. I'm gonna try and figure this out, there's a post on stackoverflow about this. A guy was talking about how in order to do it you'd need to recreate files similar to the ones that poll the actual hardware. He's basically saying you need to create some sort of mock gyroscope polling code right above the hardware level. I don't think that's the best approach, we gotta go top down not bottom up on this. I don't know much about the inner workings of android but I know this, looking at how to grab sensor data just using a plain app uses the classes sensor and sensor manager. As far as i can tell these are fed with information by the sensor event listener. That is fed by the object sensor event. It states right on the documentation "This class represents a Sensor event and holds information such as the sensor's type, the time-stamp, accuracy and of course the sensor's data." Its a generic sensor class which means we could possibly give it a fake gyroscope right?
Now, back to the sensor event listener, on the documentation it says "The application doesn't own the event object passed as a parameter and therefore cannot hold on to it. The object may be part of an internal pool and may be reused by the framework.". That means sensor event listener is literally just the messenger and should take whatever it finds as long as its valid. It seems like it will take whatever is passed to it correctly if we can make an event that it hears.
Now, amazingly on the sensor event page shows some fantastic stuff. Sensor event class is literally a 4 field class and I believe gets its values from that "hardware polling code" that sits above the hardware level. (the code that other guy was talking about.). If we can just make up some sensor events that mimic a gyroscope using accelerometer + compass and hope that the sensor event listener is configured to pick it up (I don't see why not) then I think this could be a possible solution. With all that being said, I'm just a beginner when it comes to android. I'm a college kid with a background in c and java just trying to piece the puzzle pieces together and play some pokemon lol.
Edit: So I may have been way off the mark, I'm not sure anymore. I found this though, a way to use actual custom sensors with android http : // riansanderson.blogspot . com/2012/03/integrating-sensors-into-android . html . Sorry for the spaces, I can't post links. After more java delving it seems it is not possible to create your own spoofed sensor or sensor event if your code is not in the same package as android.hardware.Sensor or SensorEvent
Edit2: So I guess unless you can get code to run in that android.hardware package, you'd have to do something like that link above and make like a fake driver for fake hardware.. I suppose if you could modify android.hardware.sensor to just make a gyroscope sensor and take the values from the accelerometer and modify those on the fly.
Try this solution
hello all from Egypt
this tutorial isn't mine or my invention you can say it's information sharing
I am Waleed and i have Huawei honor 4x which has no gyroscope at all, but i found some solution to this problem which is:
1- you must have ROOT (without root you can't do anything at all)
2- install root explorer if it isn't installed in your mobile and be sure to allow root permission to it
3- download the attached xml file which activate soft gyroscope in your mobile and place this file in your SD card
4- open root explorer and copy the xml file you downloaded and go to this path "/system/etc/permissions" and paste the file there and be sure the file exists in this place
5- reboot the phone then install any app from Google play to check the gyroscope i suggest sensor box
6- I hope this information is valuable and useful for you
thanks
Hey there,
i have to make an android application which counts your pushups, where the phone is lying on the back of you. It has to measure these pushups by some sensor, i was told to use the acceleration sensor, but the value variates very much, so i am looking for an algorithm which "erases" these in the app or find another ability to measure it. So has anybody an idea or a good algorithm for me which i am allowed to use?
It will be just for something a bit smaller like a seminar work (a very very very small doctor work)
Anybody?
I made a standalone navigation app for Wear OS! Here's the link to the app: https://play.google.com/store/apps/details?id=uk.co.onibaku.standalonewearmap
Here's the full description on the app so you can get a glance at the features:
Users can type in a location, or long press on the map to input a destination. They can choose to travel via walking, cycling or car.
The app will navigate the user from their current location to the destination using turn-by-turn navigation. Each step is highlighted on the path, with text to show you what action to take, and how long until you reach that step. The map rotates along with the device, so will follow the forward-facing direction of the watch.
The app only needs an internet connection for the initial retrieval of the directions. After that, it solely relies on GPS until the user arrives at the destination.
This (obviously) only works on watches that have GPS.
If you have any suggestions at all, I'd love to know them.
The next feature I plan to implement is importing a GPX file in from Google Drive, so you can navigate a more unorthodox/scenic route, which would suits cyclists. I initially developed this for when I go cycling, as we don't usually want to take the fastest route somewhere.
Let me know if there any burning features that are needed in this, and I'll do my best to deliver. This is a small side-project, so I don't have too much time to work on it, but I find it quite useful personally, and I hope others will, too.
Someone suggested I release a demo version so people can try it and see if they wish to buy it. I have released one here
It only has the dropped pin functionality, and only allows walking as a navigation mode. The zoom is also locked.

This is looking really good. I want true standalone navigation on my Huawei Watch 2 4G. It has a sim so loads the route standalone and seems to be able to do everything expected...i'm trying the demo version now.
One question though...unless i'm missing something..how do you exit the app? I'm currently having to force close it.
(And as a side note have you checked out the Wear OS app Ghostracer? You can import a gpx file and follow your progress on a map on the watch. Maps are downloadable to the watch, although ive never tried that. My watch has a sim so updates the map as im riding using the watches data. Heavy on the battery though.)

I had not realised that the app does not cease to use GPS whilst it is in sleep mode, so I have added a button to exit the app properly when you drag down. I've just released it now.
I have had a look at it, but it doesn't seem to work unless you have an android phone. I am currently looking into offline maps and importing GPX files. Do you know if it does that via the android app, and how it imports it? I was looking to use Google drive, as that seems to be the only viable storage solution supported on Wear atm.

Thankyou for the exit button, works great. Having tested the demo app i'm happy, and I will purchase. One further comment, the battery drain is heavy, as expected. Any chance of an ambient mode while the map is running to save battery? I may be pushing my luck, but I can only ask!
Ghostracer does indeed need a companion Android app on the phone. The gpx file is loaded into the app on the phone (using a file manager) then passed to the Ghostracer app on the watch. Maps are treated the same, but I just use the data from my sim in the watch to load maps as I ride when needed. You can follow a gpx route standalone on the watch in a similar way to following the route on your app. I am not connected to Ghostracer in any way, I just think its a wonderful app for cyclists and runners (within the watches battery limitations). And the free version allows you to test all its features. It might not be right for you, but it was worth a mention based on what you said earlier. (And the map screen has an ambient mode.... )

Great . I did play around with the ambient mode, but it was just the same as the standard google maps ambient mode. It takes away the turn-by-turn, location, and path. If I could persist these, and set the GPS to update every 30 secs - 1 minute, I'd probably keep it, but I'm not sure how. I'd like to stick in options to set the GPS update frequency, or have the screen turn back on only for upcoming turns.
That's really cool! That's essentially what I would have liked on my watch but standalone. I really don't like the idea that you HAVE to use a companion app, especially when it's not available for iOS. I know they're competing watches, but I love the price point of android watches compared to Apple's, and their features shouldn't pale in comparison by way of hardware.
How does their ambient map work, if you don't mind me asking? I'd like to look into it. What does their paid version allow you to do? I only had a paid version before someone mentioned to put the free one on, just to give people a flavour of it. I tried to emphasise the main bit, which was the turn-by-turn navigation. The search and other transportation modes were secondary.
Cheers for the feedback and suggestions, though! I really do appreciate it! Let me know if there's anything else you'd like.

Ghostracers ambient map is black background with white markings until you lift your wrist...but that might not work when using your app while driving (watch off the wrist?).
I've now purchased your app (Google made that hard work!)...all still good. One question...when I zoom the map in the map un-zooms straight back. Any way to make the zoom stick?

Do the markings include the path/trail? I've used the black background one before, and the building outlines are (kinda) white. Yeah, I do have my watch affixed to my handlebars on my bicycle.
Great - Thanks! It's much appreciated! How come it was hard work, if you don't mind me asking? Ah, yep. That was one of the first things I forgot to change! I completely forgot about it! I've made it so that if you zoom/pan, it'll stick unless you press the "my location" button again.

Hi ruggs1234, it was a long time since you wrote your experience with this app. I downloaded the demo today and I tested it. Looks like since last Google's update, the huawei watch 2 doesn't use its built-in standalone GPS. Please, would you mind to check whether you are having this problem now? The only way I got it work was by connecting the watch to a phone through Bluetooth.
Kind regards, Angel

Hello Angel,
The app still works ok on my watch, I tested it yesterday.
With my phone switched OFF I use my watches inbuilt sim to start the route (the app needs data to download the initial route, it can use the connected mobile but mine was switched off). I then switch off the sim in my watch and follow the route using only the gps in the watch. The app worked as it always has.
HOWEVER, my watch isn't running the latest version of Wear OS (it's running Wear OS 2.0, Home app 2.16). I never update anything Google if i'm not forced too, their updates often break more things than they fix. Everything I use on the watch works great and i'd like it to stay that way....
Hi,
well, I gave it a test (full paid version) - TicWatch 3 Pro 4g/LTE (all up to date). It doesn't work. All tested in standalone mode (no phone involved).
- app crashes when there is no GPS fix (GPS is on, but no fix yet)
- when I set an route to navigate (pin or search) it just endlessly shows progress circle and nothing else happens (GPS on with fix, LTE on and working)
So...
BR, Doman.
I installed the Demo version on my ticwatch 3 pro gps (updated everything to current versions and no modifications (yet))
App is starting, map is not showing, just the gps location button on the left and a white/grey screen. I can pin a location on the white screen and its actually getting a location next to me and tries to route there - but without any map showing.
Any app for Gear S3 ?
Hi all,
I have developed an application for a Wear OS, intended for a robust continuous atrial fibrillation (arrhythmia) and heart rate monitoring, which uses an optical sensor (green light) in the bottom of the watch. I'm currently limited to Fossil Gen 5 watch since my Samsung Galaxy Watch 4 won't give software access to its optical sensor.
Having said that, would anybody here like to test the app on their watches? It still needs to be improved and optimized, therefore, feedback would be appreciated. Also, it would run on other watches, however, in that case I would need to know an address of an optical sensor (Fossil Gen5 PPG sensor is 65572) so I could update the app.
I'd like to publish it in Google Play sometime later, have never done it before, it looks quite tricky, however, I filled most of the things there already.

Hi, I have tried your app, it's great that you are doing this.
I have tested it on Ticwatch Pro 3 GPS, it works correctly, shows heart rate and cardiogram for arrhythmias.
When I started the app for the first time it did not ask me to enable sensor permissions nor did it alert me that it did not have the permission enabled when I started monitoring. I activated them manually and it worked as expected.
About the PPG sensor address for TWP3 I don't know which one it is, I guess it is the same as the Fossil Gen5, because it works.

Thank you so much! Didn't expect such a quick feedback!
I'll try correcting the permission part. And it's great to know, that app is compatible with TWP3.
Just in case, keep in mind, that this app runs in the background and should be stopped manually.
Hi, I would like to try this on my Fossil 6. Do you install the .apk on the watch or phone? Sorry, I've never installed outside of PlayStore.

You can utilize this method to install this and any apk directly to WearOS.
A slightly updated version of the app, which now includes a request for permission to use BODY_SENSORS.

Hi all,
I have developed an application for a Wear OS, intended for a robust continuous atrial fibrillation (arrhythmia) and heart rate monitoring, which uses an optical sensor (green light) in the bottom of the watch. I'm currently limited to Fossil Gen 5 watch since my Samsung Galaxy Watch 4 won't give software access to its optical sensor.
Having said that, would anybody here like to test the app on their watches? It still needs to be improved and optimized, therefore, feedback would be appreciated. Also, it would run on other watches, however, in that case I would need to know an address of an optical sensor (Fossil Gen5 PPG sensor is 65572) so I could update the app.
I'd like to publish it in Google Play sometime later, have never done it before, it looks quite tricky, however, I filled most of the things there already.

Looks to me like Samsung has their sensor hidden behind this 'privileged' api, might be worth trying to request access?
Actually I was able to find a couple potential addresses for the Samsung sensor when I poked around a bit, were you unable to actually access the hardware even with the address?

Thanks for the tip. As I matter of fact I did try contacting them in the exact same way you showed, however, I the declined my request without explanation. Maybe it is because I didn't mention any affiliation with business or something like that. I'll try requesting once again.
I also tried reading all the accessible sensors in Watch 4, however, software access to the PPG sensors is restricted.
I guess the sensor you are referring to is this one:
Samsung PPGBatch Sensor /Type_String: com.samsung.sensor.ppg_batch /Type_number: 69668
Galaxy Watch 4 offers wide range of sensors and I have developed quite a lot of various algorithms, which could be implemented, e.g., continuous SpO2 monitoring (red and infrared optical sensors), confirmation of a suspected atrial fibrillation (detected by using green light optical sensor) using an ECG strip.
I tested app on TicWatch E3 and it does work on this watch. However, I noticed that the quality of the Photoplethysmogram signal is worse than what I get in Fossil Gen 5 watch. With Fossil Gen 5 watch, you don't even have to search for a good spot on the wrist, the quality is always good and it is not the case with TicWatch E3. The algorithm in the app won't throw false alarms because of that, the signal quality is constantly monitored, however, with that kind of quality it would be tricky to detect AF if it was present.
I apologize but I would like some help. I have a ticwatch E3. I apparently installed the app using Wear Installer 2. That app indicated that the installation was was successful. However, the app does not appear in my launcher. Is there something else I need to do?

You might want to consider utilizing Bugjaeger Mobile ADB as a really alternative and innovative solution to the problem of sideloading apps on Wear OS devices.
Thanks for the reply. Another question, as I said the Wear Installer 2 indicated that the app was installed. Would this app appear as an app in settings or in the launcher. If not, where is it on my watch?

Hi, I did some updates to the app, mainly in the representation of the heart rate change over time. There are some as to say, drawbacks because for now heart rate values are saved in a local variable, therefore, if app was closed and restarted, the previous heart rate log would not be saved. I also have some thoughts in adding additional screen for the parameters of atrial fibrillation if one was detected, however, still not sure what information (e.g., beginning and the end of the AF episode, duration of the AF episode, etc. ) regarding this would be relevant for an ordinary user. Maybe some of you might have ideas what info would be of utmost relevance for you.
I would love to use this app on my Samsung Watch 5. I hope you succeed in getting access to the sensors on the Samsung Watches. I think your app would be very popular!
Hi, I know it's a tech site but to anyone suffering from atrial fibrillation-one of the most common but least talked about causes is head and neck posture/atlas position, slumped forward posture- very common with the amount of time we spend on our computers- see Dr John Berg youtube channel -
A good chiropractor or acupuncture practitioner can help to correct these abnormal and harmful postures and could possibly save you from surgery or pacemaker..
Don't ignore other causes which are more serious though-especially in the lat 2 years- lots of people are getting abnormal blood clotting since having a certain injection or getting long covid.

Thanks! I haven't motivated myself to fill the request for getting the sensor access yet. It is quite complicated. Another thing that I noticed is that the raw green PPG signal from Galaxy Watch 4 and 5 is sampled at 25 Hz. Mine algorithm uses higher sampling frequency. According to the info provided by Samsung, only RED and Infrared PPGs in Galaxy Watch 4 and 5 are sampled at 100 Hz.
I am planning on improving the app by integrating it with Health Connect or with something similar. Currently the app stores, e.g., heart rate data in temporary variables, which are cleared as soon as the app is restarted. Another option was to write data in the main storage; however, data management seems tricky to me, I wouldn't want to deal with databases on my own.
Are you able to get raw RED and IR PPG sensor data (or any of the PPG sensor data)?
