Compass / G Sensor - G Tablet Q&A, Help & Troubleshooting

I downloaded a bunch of apps that show direction (compass) and leveling - none of these seem to work.
Does the G Tablet support this feature ? I know it doesn't have navigation (uses wifi) but I thought it has compass features.

Someone please reply

The gTablet has only 2 sensors: the accelerometer and the light sensor.

accelerometer

I don't see any controls for the accelerometer. Any one know how to access this?

What are you trying to do with it? The accelerometer can be accessed by any apps that use its functionality. There aren't many built-in uses for the accelerometer, other than rotating the screen?
What kind of controls are you looking for?

Just curious more than anything. All of my previous Android devices have had an "Accelerometer" setting when you could adjust its sensitivity for various games.

[Q] CM7 sensors working?

Does the current CM7 build restore functionality to the Proximity and Orientation sensors to the point where they can be used with standard apps?
Does the NT have a proximity sensor? I did not think so.

Just going by statistics from a couple of apps i.e. Android Assistant which purports to give Name, Vendor, Range Resolution and Power data for installed hardware as follows. (list not complete)
Proximity Sensor - SFH7741 By OSRAM
Rotation Vector Sensor - Google Inc
Temperature and Pressure Sensor - PMP085 by Bosh
Magnetic Field Sensor - HMC5843 Magnetometer By Honeywell
Linear Acceleration Sensor - Google Inc.
Light Sensor - BH1780gli By ROHM
Gravity Sensor - Google Inc.
Accelerometer Sensor - kxtf9_accel by kxtf9
No Gyroscope Sensor or Orientation Sensor listed
My error on the Orientation Sensor I should have said, and am most interested in, the Magnetic Field Sensor
Other apps report similar hardware available.
Besides the holy grail of Bluetooth, I was wondering if the CM7 versions have been able to natively find and activate them (if they in fact exist) or if each had to be detected and programing specially written.
Another possibility is that other necessary hardware was never included to utilize all the sensors.
In other words...
Has anyone with the latest CM7 root tried and successfully to run a compass program? I am happy with my simple Nook and Zergy root with BN access but would build a new SD card if I had a working compass for some astronomy apps.
Thanks for any additional info.
I tried a compass on CM9 and got a magnetic sensor error.

Screebl Pro doesn't work on CM7 alpha final.
I think you need to wait for next update...
Odd thing that Screebl doesn't work. I would think that it would use the same sensor for angle identification that other programs do. For instance a nice little program called Skeye can show you the night sky when you and change the vertical angle and/or rotate from portrait to landscape but it does not recognize rotation to different compass points apparently because there is no driver for the magnetic field sensor.
It appears that in my list of sensors above that anything listed with a Google driver is functional. Those without are not. But given that the manufacture of the sensor is listed, there might be Google drivers available that can activate them.
Thanks to those that did some testing

Incompatible sensors in the Evo LTE?

I've tried several different apps that report sensor data from the Evo LTE, and almost all of the sensors show no data.
Only things like the proximity sensor, light and sound register data.
The orientation sensor and compass sensor show nothing and the accelerometer shows almost no changes as I move the phone around.
The Compass app always shows North.
And yet... Google sky maps works perfectly.
I wanted to use the orientation sensor to control some servos on an arduino project like I had been with my old Evo 4G.
Have they changed the APIs, or are they using some new chipset that (almost) all the apps don't yet understand?
Use elixir 2 to test the sensors

I tested my compass app and it works perfectly.
Hmm -
Compass (Catch.com) and Compass Pro are stuck on North.
Compass & Level shows North and always centered level
Smart Compass and Compass (Droidware UK) are showing the actual direction.
Labirynth light works.
Google Sky Map works.
Elixir 2 shows:
Accelerometer: seems to be working
Gravity sensor: nothing
Gyroscope: nothing
Light sensor: works
Linear acceleration sensor: nothing
Magnetic field sensor: works
Microphone: works
Orientation sensor: nothing
Proximity sensor: works
Rotation vector sensor: nothing

Using a rom of some sort? Possibly it has broken things.
Everything checks out for me in elixir. Go have sprint run their tests on your device. Sounds like yours needs replacement

Do you think maybe sensor tests are a bit esoteric for your basic Sprint store?

Any store with a service department has a wide assortment of tests. All they have to do is plug it in

Gyro/compass and photosphere

Does anyone know how photosphere can be fixed to recognize properly the gyro and compass sensors? I've tried several roms and 4.2 camera versions and on my phone the horizontal motion is not detected at all and the vertical motion is averaged badly (~15s). So I assume there is a setting somewhere or a device link that needs to be made so that photosphere recognizes the gyro and another setting somewhere else for the time averaging constant.
Panorama works ok and that [I think] it relies as well on the gyro.
Yes, I tried GPS Status calibration, letting the phone on a flat surface with photosphere turned on, extreme rotations around all axes.
The razr doesn't have drivers for a gyroscope, just compass and accelerometer so photosphere will never work.

But opening GPS Sensor and Turbo GPS I see the absolute radial tracking is correct. Google sky works and so does panorama. I assume by this that the gyro (measuring speed of rotation) is not really needed since it can be determined from differentiating the magnetometer.
Maybe a custom device driver can be built that emulates this? Would be interested in doing this.

[Q] accelerometer problems

hi, everyone.
after i received my moto e this monday, i have installed lollipop 5.1 stock from twrp backup.
now i'm realizing that the acelerometer is not working properly; neither the panoramic capture, nor google sky maps is working.
does anyone have this issue?
what could i do?
well, i've readeing that there's no compass in the moto e, so im wondering if skymaps, and other orientation programs are supposed to work well on this device.
could anyone tellme if skymaps is working for you?
thanks in advance

moto e 1st gen doesn't have compass..
so any app that shows directions i.e (north,south,east,west) when the phone is held horizontally /Orientation apps will not work... even Google maps doesn't show the maps according to phone orientation.
it just shows the map in north direction.
"The accelerometer is a built-in electronic component that measures tilt and motion. It is also capable of detecting rotation and motion gestures such as swinging or shaking.
The most common use for it is to activate auto screen rotation on mobile devices when the user changes their orientation from portrait to landscape or vice-versa ."(courtesy: gsmarena)
the accelerometer has nothing to do with compass or its applications.

oh, that a shame. it's a fair sacrifice for the price, i guess.
thanks for answering, anyways.
