Hi，
I am trying to read the device accelerometer when the phone is placed on a
desk with screen up，I expect 0 on the x-axis and y-axis，-9.8 at z-axis. But I
get
x:11，y:-37，z:-24(decimal part ignore).... What is this？ I read the doc of
accelerometer， does not make it clear. Could you please help :
1. Why x and y are non-zero？
2. Why the value is so large？
Thanks ！
