Can you get the height that you are holding the phone?

Question

relative to where it was before,

so like holding the phone up and then moving it back down to normal playing level and detecting that that happened?

or is magnitude with the accelerometer the best i could do

You can get the change in height from this physics mechanics equation :

Displacement= 1/2(acceleration)^2 (assuming device is at rest, zero initial velocity)

Because distance and acceleration are vector quantities you can determine the displacement in the a specific direction as well. For example get displacement in x direction:

Displacement in x direction = 1/2(acceleration in x direction)^2 (zero initial velocity)

that seems like what i want, sorry can you do an example with numbers to help with my dumb

Here is a link to the general stuff behind the equation: http://hyperphysics.phy-astr.gsu.edu/hbase/acons.html#c2

Displacement is the output of the function, or what you want. The magnitude of Displacement is distance. Acceleration is the input of the function and the output of the function that calls the internal accelerometer of the device.

Lets look at just displacement in the x direction, say the accelerometer reads "3" in the x direction.

Displacement in x direction = 1/2(3)^2 = 9/2
