This I have not noticed. Please elaborate and share more information and I will investigate this.

Did you try any software repair/reinstall?

List l = mSensorManager.getSensorList(Sensor.TYPE_ALL);

Iterator iterator = l.iterator();

Sensor s;

while (iterator.hasNext()) { kk = kk + iterator.next().getName() +"\n";; mEditor.setText(kk); }

Using getSensorList(Sensor.TYPE_ALL) on android gingerbread show more sensors than on android 4 update.

Here is a link to the program that do it.

if yo want more info i also have the source code for eclipse.

uhm... is there a shortcut key for screen shot or should i download an app coz' there's no screenshot on ICS.. D; but gravity sensor, linear acceleration sensor and rotation vector is not on the list..

Well if the screen rotation works and walkmate and such work, then I suppose these sensors work. Maybe it's just a compatibility problem with ICS in your sensor list app?

hey, you can take screenshot in ICS by holding volume Up + Power Button (in portrait mode) and volume Down + Power Button (in landscape mode). Hold it for about a second,and try to press them together also/.

Degraaff might be right... and cant seem to take screenshot through that button u've suggested LOL! maybe it doesnt work on ICS anymore

I have the same problem with both Xperia active and Xperia arc: Afte update to Android 4.0 some virtual sensors are gone, namely gravity sensor and rotation vector sensor.

Screen rotating and most other orientation-based features are not affected but some specific apps that use the rotation vector sensor are.

Below is a screenshot from the Sensor-List app on my Xperia active, which shows the available sensors. Before the firmware update the rotation vector sensor was definitely available for I've used it myself in an app I developed. Unfortunately my app won't work anymore since the update...

From a developer's point of view using the rotation vector sensor is much better than using accelerometer and magnetic field sensor directly because with the latter much more calculations and filtering is needed.

Edit 13/02/11: Well, a nice DIY solution for Android developers is to implement their own rotation vector sensor, as described here.
