Is it possible to simulate a gyroscope sensor using accelerometer and compass ?
(i would like to have photosphere working on my l9II which doesn't have a gyro sensor)

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
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
I'm having trouble in my proximity sensor.
as it disables the stock rom or any kitkat?
This is the usual description about the rotation vector sensor:
The rotation vector is a virtual sensor in Android that depends on the accelerometer, gyroscope and magnetometer (digital compass), using these inputs it is able to determine the orientation of the device.

I have 4 devices here, all 4 (according to the GPS Status app) have an accelerometer and magnetometer but no gyroscope. Yet 2 of the devices do have a rotation vector sensor and the other 2 devices do not:
Motorola Moto G (osprey): CyanogenMod 12.1 - NO rotation vector sensor
Samsung Galaxy Note 8.0 (n5110): Resurrection Remix 5.7.4 (cm13) - NO rotation vector sensor
LG G-Pad 7.0 (v400): Resurrection Remix 5.7.4 (cm13) - rotation vector sensor WORKING
Motorola Atrix HD (mb886): CyanogenMod 12.1 - rotation vector sensor WORKING
Obviously the presence of the rotation vector sensor is not a question of the CyanogenMod version (see above). On the other hand it is supposed to be a virtual (aka software) sensor.
So where exactly is that sensor implemented? And why is present on some devices and not on other devices? Any help pointing me in the right direction will be greatly appreciated.
Hi, I am having this huawei p20 lite Indian version which does not support gyroscope as per company's announcement.. But I can able to watch 360 degree videos of Facebook by rotating the device which can be enjoyed only if there is gyroscope in device. How it is possible. Whether this device have gyroscope hardware or due to geomagnetic rotation vector and proximity sensor.. Please clarify friends
