I have experience with GPS related APIs in iOS. It’s a fucking nightmare to calibrate sensitivity and background activity. They keep changing parameters without warning or documentation. They aggressively suspend applications and services, even those categorised as navigation apps, unless a very particular set of criteria are met. Achieving background navigation was basically black magic. Every time we got it working, something would break. Apple exempts themselves from all of these requirements for their own applications. They have access to the full specs, and have lots of advanced warning when change is on the road map.
