My phone, as below, now do not have the inbuilt compass app (it was there but missing after update !!)


Now found that the one I used from GPlay, is showing "not compatible for device" at Gplay !


I need advise for a simple free (no ads or iap) compass app.

Hi Anand,
give this a try. Very complex, maybe a little overkill for your needs. Written with B4A, no advertizing, no sim, no internet access needed. It's using GPS, orientation sensors and the magnetic sensors. RedMi9 should work.

Developed with B4X not found on this server ? so I chased it down a bit:

and if you were to post a message tagging @PhilN then perhaps you could team up to reincarnate the app. ?

I am wondering whether the gyro in gyromagnetic,compass implies that your phone needs to have a gyroscope sensor, though. Accelerometers are common, gyroscopes are not, at least not at the cheap end of the Android spectrum where I live. ?

Any solution for this kind of problem ?

Does the phone have a gyroscope? I suspect many compass apps use the gyroscope (if present) to augment the magnetic sensor so that the compass needle is more stable (averaged/smoothed/damped).

My first smartphone was an iPhone 4, purchased specifically because that was when Apple added gyroscope sensor, and I was into IMU/INS bigtime back then re: gathering map/track data for OpenStreetMap.

With GPS on, it reacts to GPS-Data. You have no position fix yet, there is nothing to see in Lat/Lon. Try to switch GPS off. The LED on the button turns to red. Compass is switching to orientation sensors and gyros.
Your orientation sensors are not working or the sensors are not calibrated (the "INFO" on the upper left button is in red colour, should be white colour, when well calibrated). Move the phone around all axes to calibrate the sensors. "INFO" should change from colour red, via orange and yellow to white). Then, if sensors working you should see a reaction by turning the phone around x-axis. Lay it flat on a table (the blue arrow indicates this), give it a turn. Make sure the compass is in "HIKING-MODE", not in "CAR-MODE". To prove that, do a longlick on the mode-button to get into the configuration-settings. Display "turns" to the opposite, then. There are the hidden configurations. When done, click back to go back to the compass-view.
If it does not react to anything, there is something wrong with your phone. If you own another one, try it there to get a feeling what should happen and what not. Read the documentation please.

Maybe this is the reason, for your problems in downloading compass related stuff from Google. If your phone reports limited capabilities (independing from what it should by the manufacturer) then Google prevents downloading it, because it will not work.

Is it a refurbished phone? Maybe the sensors really don't do what they should. I have a program for testing the sensors. Unfortunally it is to large for upload here.
