It's time for me to upgrade phones, and I have a question...
I notice that the HamGPS app tells me my phone has an accelerometer, but
no magnetometer; lack of the latter doesn't seem to have impacted the
accuracy of the app though.
I use AMSATDroid, Heavens Above, and ISS Detector apps for tracking the
birds, so my question is how necessary are these two sensors for getting
accurate results from these 3 apps (and others)?
In other words, do I need to look for a phone which has both sensors, just
one of these, or does it matter?
