hello friends,
I am collecting accelerometer and gyroscope during user movements with "startAccelerometerUpdatesToQueue". Data coming looks good even if I call it from background. But as soon as user gets iOS update (no matter beta or official release) sensor data becomes with gaps and not usable. This happens until user will manually restart the iPhone. After restart data becomes very clear and good.
For start collecting sensors I use startAccelerometerUpdatesToQueue and location events to start accelerometer updates from background.
