Hi,i just bought this gear fit,it helps me keeping track on my daily activities (on the watch) and stuff like that but i hate that s-health or samsungs fitness app doesn't work on other devices (i have an LG G Flex). Then i found out about endomondo that they support the gear fit so i downloaded the app. After i installed it a new icon on the watch appeared called app connect and endomondo appears there, but when i press it on the phone i get the message Not a Samsung Device or something like that. Has anyone tried this app and can confirm that works with gear fit? Or is it because i have an LG G Flex?
Or does anybody knows any other apps that can make a graph for your activities and can connect to the gear fit?
Thank you.
Endomondo works great with the gear fit. I think Strava used to support it but now does not. I do not have a supported Samsung device but I do have a Samsung phone and I had to change the build.prop file to get it working. I suspect you would have to do the same as in the link below. It may make any LG links unstable however. Copy original build.prop to your PC and if your phone hangs, after modding the file, then push it back using ADB. Good luck.

It works with my ANT+ Garmin Heart rate monitor. It has 3 displays you can customize. See pic.
Hey
Is it possible to use gear fit as instant heart monitor.
To enable working in aerobic area for example.
That means, that gear fit alarms when you are under or above aerobic state, (eg. under 120 hb/s and above 150 hb/s).
Thanx for any kind of help or suggestion.
If you set the Gear fit to track Exercise>Walking or Running, it will show a constant pulse rate but I see no where, app or other that will set HR alarm zones without using HRM, phone and app.
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
Dear Amazfit-Users and developers,
As you will have noticed all your health and activity data gets uploaded on the Amazfit servers (located on some Amazon AWS-Cloud) when using the obligatory Amazfit App on your smartphone. Furthermore I was able to identify some system data like your installed apps and settings being transferred by analysing the data logs with "Grey Shirts Packet Capture".
Amazfit privacy statement: https://support.amazfit.com/hc/en-us/articles/220266468-Privacy-Policy
Well, not a big deal as we can just use a firewall/iptables to prevent the frequent, battery and data consuming transfers.
BUT: Updates of the firmware and especially the assisted GPS don't work anymore -> "AGPS has expired, gps searching will be slow Please connect the Amazfit watch app to update it"
Did anybody already deal with the problem?
Do you have any idea what server the A-GPS data is derived from (for setting some iptable exclusions)?
Best regards
I know the thread is old, but in case you're (or anyone else is) still interested in it, the AGPS data is retrieved via the following URL (only works if you have a valid token unfortunately):
https://api-watch-us.huami.com/apps/com.huami.watch/fileTypes/AGPSZIP/files?days=7
For manual updates I have switched to PACIFIED.
Dear Gerii,
Thanky for your answer! Do you have an idea how the token is generated?
How about PACIFIED? Does the AGPS-data update work without the Amazfit App?
Greetings

No, unfortunately not. But I didn't look into it that closely as the GPS quite good also works without it. It is usually fast enough to find a fix during my warm-up exercises, so it isn't that big of a deal for me.
As far as I know it only works with the app, but I don't use the Wifi on the watch.
Hi there,
i'm trying to build a companion app similar to watchdroid with wich i can send data to the watch and display them on a widget/springboard.
In my case i wan't to have my blood glucose level on my watch as i was used to with my android wear watch.
I have a simply app made with taske wich can read out a json from my nightscout site. This sadly work only via wifi.
Main problem is the bluetooth comunication. i've tried so many simply bluetooth apps and librarys via sideload. I can't even tell how many. Non of them worked out. Only some worked in watch to phone direction but not the other - desired - way. In almost every case, my phone could'nt even find the watch.
But since watch droid got it working, i know there is a way.
There is another way to get data to the watch: the notification system. Since i also could'nt get the notification listener to work on the watch, it is also not a starting point for me.
Last chance i see is automizing watchdroid and sending a file at a regulary scedule and reading this from the widget.
For the moment i just use Notify and fitness cause the Phone notification with my glucose level is persistent and the huami app ignores persistent notifications.
But get a new notification with my glucose level every 5 Minutes. On the phone the notification gets just updated, on the watch i get a new one. Over the day the notification stack gets fuller and fuller...
I'm not talking about geting this into a watchface, thats the next step after the next hundreds of steps.
Any help and tipps are welcome.
When a notification is dismissed on the phone, it should dismiss on the watch.
If you have the source to this app, you could make it dismiss it's notification and send a new one.

Hello,
what application do you use to get a notification every 5 minutes ??? you use a FreeStyle Free blood glucose sensor ??? I will be very happy to read you to know if you succeeded !!!

Yes, it's freestyle libre with ambrosia blucon nightrider for nfc readout and transmission every 5 min. The app i use is xdrip+.
The notification is persistent to keep the data collector service running, to show the value on the notificatiin icon even on the aod of samsungs.

ah yes anyway, the price of "ambrosia blucon nightrider" as we say at home "it stings the eyes". before you give me the answer I was wondering how you did to get back the FreeStyle scan, so I understand. on the other hand to use the nightscout, it is a little the course of the fighter ... a lot of account to create. damage that the app glimp or other does not regroup suddenly!
It's currently my intention to build a framework for both phone and watch to allow apps to get data from the internet at some point in the next few months. I'm stuck with work to do at the moment so don't have any time to put towards projects (especially not big ones like that) but in the future - probably
I'd ideally also like to get Android Wear (not Wear OS, it's an old version) working too, to allow at least some companion apps to function (Sleep as Android, Keep etc.). I've got the framework working fine (which does improve app compatibility, but no communication still severely limits what they can do), but the two way Bluetooth connection throws an error that I cannot find any documentation about, so it's on hold for now until I have sufficient time to investigate properly
This would be awesome to have a framework like this. In my case i would'nt even need real internet access, due to the web service is localy provided by the xdrip app. But this would open so many things and possible options to code. Let me know if i could help. I'm also short in time but willing to help.
Getting Android wear working on the pace/stratos would also be great. I tried out sideloading the micro apk for wear of xdrip+ and it worked out better than expected. No crashes from the app and even the integrated watchfaces were selectable. Of course there were no data shown and no low power watchface.

It might actually be possible to build a newer version of Android, source code exists for the CPU and MIPS sources exist all the way up to Oreo, but again that would take time I don't have (and space for that matter)

Hi, great news. Will this work on Amazfit BIP ?
Since the Bip does not rely on the AmazFit Watch app, i'd say no.
Can you show on the photo the indications of the xdrip on the watch? how it works.
Hi, i'm now trying to integrate quinnys library into xDrip, to make thinks easy and to allow 2 way communication.
Since xDrip is a really big and complex project + i'm a noop i'm having trouble with providing a switch in the menus and finding the right place to start the service from. Maybe someone can help me out again.
I am also really interest of amazfit bit. I saw now, xdrip have one section called "amazfit synk service" look like can connect with this kind of phones. Are there news to see the value on the display?

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.
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)?
