First: The barometers are very precise, but not accurate.
If you place 10 Android phones next to each other on a table, you can find barometric pressure differences of up to 3 mb between devices.
Fourth: it is not yet possible to get a completely accurate altitude reading using the barometer in a smartphone..

What kind of data is elevation?
One type of continuous surface data is derived from those characteristics that define a surface where each location is measured from a fixed registration point. These include elevation (the fixed point being sea level) and aspect (the fixed point being direction: north, east, south, and west).
Where can I download digital elevation models?

How accurate is Google Earth elevation data?
A vertical accuracy study found the root mean square error (RMSE) of GDEM data is 8.68 meters when compared against 18,000 geodetic control points in the USA . LIDAR-derived elevation data are available for some coastal states and inland states at a resolution of 1/9 arc-second (about 3 meters).
How do I get elevation data from Google Earth?
