Question Compass apps not agreeing on north position - Samsung Galaxy A52s 5G

I own an A52s 5G and have a problem where all the apps based on compass that I use don't show the same values. Samsung's own panel overlay, Stellarium, ISS Detector and Google Maps all disagree on where north is, some more than 20 degress while others 1 or 2 to either west or east. I don't own a real compass so I cannot measure with accuracy where north is and say which app is more accurate, but I am sure that they shouldn't be showing different values. Of these apps I mentioned ISS Detector is the only one with a compass offset correction option, which doesn't solve much. I've already tried the 8 drawing calibration method and rotating on the axis one on each app, but have not got any different results. I would be grateful if anyone could help me fix this problem, or at least give some hints of what might be causing it.

(REQ) COMPASS for Blackstone

Hello guy`s i was searching in internet for such a application like this but i don`t find anything cool also i think that everyone need to have COMPASS in the device and will be usefull.
So if anybody have idea or someone from the dev.. can make COMPASS to run in full screen on our Blackstones its posible to use GPS data or to use the G-senzor will be AWSOME!
Thanks in advance
I was looking for an app like this as well recently but came up with nothing. I've seen the one for the iphone, it's pretty nice and simple.
I would be very interested in having something like this on my HD.
I don't understand how you could really put a compass in without the device actually containing a compass? I suppose using GPS it would be possible, but you'd have to physically move a few metres in a particular direction for it to know which way you're facing in order to tell you where north is in relation to yourself.

I know very little about the iPhone, but I do know the G1 has a built in compass and has various compass related applications which use it.
you can have a compass, i think, in NoniGPSPlot in the window "satellite"
Have a look at RichesseGPS.
Its free and does the job well using GPS to triangulate your position and bearing.
One must have a compass in the device to have it in the software. All Windows Mobile 7 phones will have compasses in them... current WM phones do not...
Google G1 has one
The iPhone has no built in compass sensor as far as I know and I am still at a loss of how exactly this compass app actually works.
As far as I know, GPS programs generate your bearing (direction) based on your previous location compared to your current location. That is all fine and dandy provided I continue in that same direction. However, if I were to rotate my body (and the phone) 90 degrees to the left or right, my bearing wouldn't change until I began to walk in either direction.
What I am saying is, GPS based compasses would work and do work in navigation applications such as Tom Tom or Garmin... however for something like a hand held compass it would simply not work very well as an actual compass.
Did a bit of research on Compass Go - the iPhone compass application seen in the "Itchy" Commercial
Apptism -Compass Go Application said:
Find your way back in the easiest way!
Use Compass Go whenever you find it easier to follow an arrow than to read a map.
1. Tap 'Set Target', 'Use current location' and you are done!
2. To find your way back, watch the target arrow and distance change.
3. As you get closer, the background changes from blue to orange to green.
Perfect for finding your parked car, a place on a beach, a place in the forest or any situation where a map doesn't work well.
Application features:
* Simple GPS compass
* Accurate sun compass
* Target finding device
* Geocache search tool (set your target coordinates manually)
* Multi purpose navigation helper utility
* Magnetic declination indicator
* View positions in the map application with driving directions.
When using the live compass, make sure you walk in a straight line to get as accurate compass readings as possible.
You may also use this application together with an ordinary compass to achieve a very exact target finding device. Most useful in forests and other situations where the map doesn't work well. The application also has a built in magnetic declination indicator (red/white arrow) which compensates for the local declination.
If you don't have a GPS iPhone, your direction may be very wrong at times. Use the sun compass to confirm your direction. Generally it works quite well when there is good cell-phone coverage. You have to move more than the (±) accuracy limit to get a new reading.

So from what I understand this application works on GPS bearing... along with a few other features. However, just like the application listed below, in low signal areas it recommends you use the sun compass.
An application that just utilizes the sun and current time in order to create a compass heading is shown below.
Something like this could be easily made for the HD.

There should be a way to use GPS to determine direction. I think that's how the compass in tomtom works.

this is quite true..but what if you combine data from the G-Sensor?
i.e you would have to move a short distance to obtain a GPS bearing hence initialise the compass then (assuming the HD was facing forwards at the time) use rotational data from the G-Sensor to maintain the compass until the next GPS update. Of course this would still only work if the HD was always held by the user in the same orientation????
i am not sure how accurate the G-sensor is or what sort of data it returns?
but the combination of the to could theoretically produce a pseudo-compass
if i get time i may have a play with this theory..i am sure somewhere i have a G-sensor SDK...just need to figure out how to access the GPS,
Can anyone confirm whether the g sensor supports rotational data i.e. when held flat and you turn around?
struggling to find spec on the sensor (only done a quick search)

Yes, this has been spoken of in nearly all of the previous posts. Your current GPS location is compared to your previous GPS location, a line is drawn between the two and that is your bearing. (direction)

The G-Sensor is just that, it senses the force of gravity or acceleration in 2 directions, an accelerometer. (AFAIK it is only a 2 axis unit, although it could be a 3 axis but that would seem unneeded) When the phone is laid flat, this is seen as tilt both forward and back along with side to side. When the phone is held upright one directional is maxed out where the other will detect tilt rotation of the phone left and right. (Or swinging of the phone left and right, this part is key to perhaps getting this to work)
The most predominate force, gravity is always down and because of this it is what one would usually use for screen rotation and games.
What you are thinking of is a gyroscopic sensor, a sensor capable of reporting rotational information, which would be very nice however is not included on our device.
However all hope is not lost, our sensor is capable of telling us acceleration in the left or right direction. So if you are holding the phone upright and rotate your body left and right, the acceleration would be recorded by the sensor. One thing you can try, is based on the acceleration and time (start and stop time of the acceleration) use this to try interpret how far the user has rotated themselves. Through some basic physics equations one could ROUGHLY give an idea of how far one has rotated from the predetermined north direction.
Several problems persist through this method, as simply how far the phone is held out from your body can greatly effect the arc length of the rotation resulting in an over / under estimation of the movement based on the acceleration data captured by the G-Sensor.

thanks for confirming my suspicions, after playing a little with the G-sens SDK i realised this.
dam, if only it was gyroscopic!....
but then i suppose i could say dam if only it had a compass!! lol
anyways, nice to see some discussion at a technical level rather than just a simple "not possible"
cheers
On a Raphael Rom I noticed a reg setting called "Dcompass" in the drivers, and ECS.dll listed. Does the Raphael have a compass built in?
i have a gps compass but i dont know how to upload
personnaly i use GpsSpot (to find the way back to my car ), it indicates the direction using an arrow and distance to target . Very simple interface.

A-to-B (GPS turn by turn Navigation - FREE!!!)[MOD EDIT: READ MY POST!]

Just found this on the marketplace and I have to say... pretty awesome. This is what WP7 was missing. Although its clearly in the beta stage it is pretty good for a V 1.0.
A-to-B is a Turn-by-Turn application built to demonstrate some of the capabilities of the ArcGIS API for Windows Phone. Warning: The application is meant for demonstration purposes only! Do not rely solely on the suggested routes or instructions given by this application. Features: - Turn-by-turn routing. Sound notification when a turn is coming up. - Add often used destinations as favorites. - List of recent destinations. - "3D view" when in navigation mode with easy accessible "zoom in/out" buttons. - 2D Map for browsing the map supporting pinching, panning etc, and pick new destination by touch'n'hold on the map. - Easy accessible "Recalculate" button if you go off the route and need a new route from your current location (because of service restrictions, the app is not allowed to do this automatically). - Routes all over US (support for Europe coming in a future version). - Worldwide map (detail may vary).
You can read more about and get the marketplace download link here
Nice find I'll have to check it out.
And so I just did. I've been playing with this for an hour not bad, not bad at all I'm going to have it set up in the car on the way into work. I'll post how it does on the highway. But it gave the correct route that I take. But I want to see how it does when I'm actually driving.
Morton you made one very nice app wit a few minor tweeks this thing will rock well done dir well worth the effort

Here's hoping for a UK map!
finally...very good
awesome find I can almost retire my Tilt2
Keep it coming guys, honestly I don't research the app market because I can get all reviews and such here at XDA
This indeed looks fantastic. One question though:
Which map is it actually using? This one has the outlines of every single house or building in my neighborhood and it is VERY accurate. I really like it.
Will it support pinch to zoom?
Partial support in the UK
Hi all
I have installed this on my phone in the UK as a trial. It works and in map mode I reasonable moving 3D map like any normal Sat-Nav. There is no car/arrow on the road to indicate precisely where I am, but the basic mechanics. It can't find any addresses in the UK so I guess that's not yet supported on the server side, but this application clearly has huge potential.
I think whoever gets there first with a fully functioning turn-by-turn sat nav in the marketplace is clearly on to a massive winner.
Cheers
andrew-in-woking
On US 95 in MA I, had an arrow up showing my car. it had all the off ramps and had my destination pegged down perfect. Also there is a speed indicator I was doing 70 mph, it had me doing 71 I can handle that. Like said before, it could use a few tweaks here and there. But overall this Nav app is darn good.
It was pretty nice and accurate getting me to work this morning, but it couldn't figure out my home address. Kept on sending me to weird parts of town.

Maybe this sounds stupid, but how do you know you were doing 70mph? Using your car's speedometer? In which case, have you had it manually recalibrated? Usually a car's speedometer is not accurate (though it normally shows that you're going faster than you actually are).
I'm going to download this now, though I'd be interested in maps of UK and Australia, so I'm not sure how useful it will be to me yet.

Please release this for the UK - awesome stuff!!!!!

Hi all, it really looks amazing.. Is there any way I can see how it works when i am in Europe? I just want to see something like preview - e. g. select two destinations in USA and than see how it goes. Thanks
Fact of the day! - Generally, Sat-Nav's register a more accurate Speed than the average Car's Speedometer. Speedometer's are configured at manufacturing to register a faster speed than what the car is actually going, this is to compensate for Tyre wear and other wear-and-tear happenings that all cars suffer from over time.
What I have noticed about this so far as that if I'm zoomed in relatively close.. not SUPER close mind you, but maybe 2 or 3 zoom levels back from the closest zoom, that it doesnt actually register the map, says map data not yet available... shows the route the of the road... the path but not the surround streets, weird. This only happens in certain area's of the city I live in too, not all over. Its like the map data just isnt there which I find odd. Its not like its loading a satelite photo so I dont know why it would do this. I tried xmaps from the marketplace the other day and it didnt have this problem. Id understand if it was a satelite image as you cant zoom in close to those sometimes, I used to have that issue in google maps where you would zoom in and it would just say you were too close.
Otherwise I LOVE this thing and am so happy I found it in the market the other day. Just an awesome APP

Barometer sensor

Hello everyone!
I have a question regarding this M8. In the specifications it says that there is a sensor for the barometer. I would like to know how this feature is used. The software for the weather of Sense 6 supports and uses this sensor?
Thanks in advance!
Says John Celenza, the lead meteorological developer at Weather Underground, "the barometer is probably used on the phone to aid in correcting altitude measurements by the GPS." In other words, the barometer is more likely than not intended to be a source of supplemental data for the GPS sensor, adding altitude measurements for increased accuracy. The atmospheric pressure is directly related to elevation, so a barometer can very easily be used as an altimeter, measuring your altitude.
Ignore the post above!!!
You can see live barometric readings in the HTC Weather app. Only visible in the "Now" tab and only for "current location".
change setting
Is it possible to change HTC Weather's display for Barometer from millibar to inHg?

Google maps now with "compass"

Hi guys,
I'm not sure if this was there before, but today I updated google maps and figured out, that the map is now rotating if I move the watch, almost like it's using a compass. As far as I'm informed the watch does not have a compass sensor.
I think that is really some nice addition though I have to see how this works when I use it during navigation.
Cool. can you link photos or even a vid of this working please?
Just wondering, don't you have this feature available at your watch? The Google maps update from December, 4th (9.18.1) has to be installed on your phone. You can toggle the compass mode by clicking on the small compass symbol which will change from northbound to rotating or vice versa.
The compass symbol is only there if you pressed the "locate me" button before, so your location is highlighted by a blue dot in the center of the map. If you start to scroll the map, the compass symbol changes to the "locate me" symbol and the orientation of the map freezes.
That's also the reason why I have some concerns about screenshots as I do not want to post my location by screenshots in forums.

No it does not point to the geographic north, your observation is correct, it's not a real compass.
I believe, google maps changes by accelerometer, and position of when the map was drawn.
Huawei watch with it's 6 axis accelerometer can work as a compass, and there are already apps to use it as such.

Just looking at HW with rotating Google Map...
Strange thing is that while turning the watch the map rotates in the same direction as watch but faster. This is wrong imo. It should move in the counter-direction, basically keeping map locked to earth. I see no use for the rotating map as it is working now...
Any other ideas about this?

Tracking "exercise" and other activities

Hi all!
I am wondering what the "exercise" tracking option is exactly. I could not find any description for it anywhere. Does it mean weightlifting specifically, as the small logo suggests?
Has anyone found a way to track generic activities that are not specifically available? Such as martial arts, rock climbing or inline skating?
Thanks for the answers!
"Excercise" should be any generic activity where you want to have HR measured in realtime and stats recorded as a workout.
The band is aimed at tracking activities which involve changing your location (walking, running, biking or swimming). It measures distance with GPS and/or steps (based on the activity). It can't measure and show any specific information for "stationary" sports like martial arts or climbing, so you won't find these in the official application. However Notify & Fitness offers many different types of activities, even though it's probably more for statistic purposes than anything else. There might be different calories profiles for each activity, but app or band can't really know how intensive your activity is, so it is mainly a guessing anyway.

Thanks! So the "Exercise" activity is exactly what I'm looking for. Measuring HR and stats for any unspecified workout. Perfect! It would be awesome to have something similar that also includes GPS in the log. To track things outdoors. Maybe with a future update, I submitted a request via the app.
Anyone who would also like this feature feel free to submit a request through the feedback function in the app
Thanks for the tip with N&F too!

Well, for an outdoor activity with GPS you already have "walking" exercise. If you want more categories, N&F is your best friend, additionally to the type of activity you can also define what do you want to measure, if you want special notifications (too high/low HR, moving between HR zones etc.). Definitely worth a try - but with a word of warning - don't get discouraged by quite complex UI, it takes time getting used to it.
