Still having issues with height above ground in the app being incorrect. I am on 4.1.21 on Galaxy S9+. Height usually stays in the teens even when at sevaral hundred feet. Flight record altitude appears correct. ideas?
That is a head scratcher and never seen that before. My first inclination would be to find another device to load the software and see how it reacts....that would help determine if it is the Spark or the Device.
