So, now that my plants are...uhh...under a different type of light, I find myself dealing with TONS of flicker in the cam. Does anyone know a stock cam app or application that has the option to change the Hz? This will help IMMENSELY with combating it. This flicker sucks and really kills some good plant shots.
Also, just to clarify, Im NOT asking for warez. If theres an app I need to buy from the market, thats fine.
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

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
I'm hoping someone can help. I bought the P9000 as a low cost phone to demo Cardboard apps. It has everything I need, a good screen, copious memory, SD card storage, and all the required sensors.
Except it hasn't worked correctly, once. There is a drift to the left which makes VR apps impossible to use and there seems to be some mismatch between the viewer and the screen. Regardless of which viewer I use, having scanned the relevant we code and selecting the corresponding viewer profile, there is always a "double effect" the two images are not calibrated correctly so the entire experience is broken.
Does anyone know how to fix this? It's been present in every stock ROM and is also present in Aerom V4.
Thanks
You can try calibrating the gyro in Service Menu
Dial *#*#3646633#*#*
Go to Hardware Testing Tab > Sensor > Sensors Calibration > Gyroscope Calibration
Clear calibration, then calibrate for 20 od 40% tolerance (try what works best for You)
That's great 40% works and stops the drift, any hints on the overlay problem?
It's the distance between your eyes. The phone is a big screen and cardboard needs to be calibrated accordingly. Find the QR code for a similar sized phone, and use that. The QR code on the cardboard set I got produced the same problem, so I scanned a QR for an oppo phone with a5.5 inch screen. Worked for me.
I thought that too but it's not the case I have a number of phones with a 5.5 screen and I don't have this issue with them. I've got a VR headset which allows one to adjust the distance from eye to screen and the distance between the lenses. I cannot make this phone work properly in Cardboard.
The 3D scanning app is now available on the Huawei App Gallery.
initial impression is it's a PITA to try & scan something.
Uses the front camera and its "interesting" trying to read the on screen instructions as your trying to scan

Agreed first few goes were awful, takes a while to get the hang of it. The key seems to be to keep the phone pretty still and slowly rotate the object , easier said than done though. Took about 10 goes to get something semi decent and then half its head was missing!
I first tried with a doll and it turned out just fine. I then wanted to try with other stuffs but it didn't turn out so well.. Also I noticed that my hand too gets modeled along with stuffs other than doll, like a well decorated chinaware... Why hand?
If this software is well tweaked then it's going to be a mega hit coz AI will, or I hope it will get better at, adding lighting and shadow info into the ARed model. Lots of scope Huawei guys, just enhance them and don't stuff in kiddo games into your future updates.
Can some of you guys post screenshots for those of us who don't have the phone?
Is it possible to post apk?
Got an article with screenshot
https://www.miscw.com/huawei-mate-20-pro-3d-scanning-camera-3d-live-maker-is-now-available-17752.html

i would really need it to scan faces. it does not want to start
any ideas?
thank you
You can create a new horror looking toy using this app
I am getting frustrated with the 3D thing, it is capturing my hand as well (while I am trying to rotate the model to clear blue spots), besides the image is not highly detailed, specially of those of sculptures n figurines. Is the AI programmed to consider only fluffy dolls?
Anyone have the apk so I can try it on the Mate 20 X? Can't find it in the Huawei section

The scanning feature can't work on the rear camera, it's able to scan in detailed 3D by using this device's dot projection system. Only one other Android phone has a 3D dot projection system, the Xiaomi Mi 8 Pro. This is the first time it's been utilized for something else than face recognition.
Anyone know what format the 3D image is stored as?
Looking forward to getting my Huawei 20 Pro this weekend to try this!
I've played with the app last night and managed to scan a few objects in suboptimal light conditions.
It worked well with soft toys but I got poor results with hard objects (model cars).
The 3D objects are stored as OBJ files and can be shared in GLB File Format.

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.

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.

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)?
