Walls, vehicle roofs, tall buildings and other obstructions can block line of sight to GPS satellites.
Locating all visible satellites can take several minutes, with accuracy gradually increasing over time.
GPS accuracy varies depending on the number of visible GPS satellites.
To improve the accuracy, make sure that you maintain a clear view of the horizon in several directions.

My cousin had an old analog barometer based altimeter that you had to guess about the accuracy because of the variances of the local air pressure. When the weather was rainy the altimeter would read low. When the sun was shining, the altimeter would read high! That is my problem no longer. Now the altimeter judges my altitude based on GPS. Hip hip hooray!

Very accurate. Neat that it has built-in compass. Tells you if GPS signal is strong or not and adjusts altitude accuracy accordingly. Also can switch to map mode and set so that the map stays stationary even if you rotate the phone.
