I did also expect Linear acceleration sensor event would use gyroscope to give out pure movement acceleration ( without gravity ) on phone's axis. But with actual device I found the readings bad and now saw this message. So still gyro not used in any other sensor events ?
I would like to get pure accelerations which do not include gravity. As per definition Linear acceleration should have done that by combining accelerometer as well as gyroscope inputs, but currently it's not and left to developers. So any links to achieve this or would help on this ?
