The chassis dimensions speak for themselves. The Galaxy Tab S, right, is slightly longer, narrower and thinner than the iPad mini 3, left. That makes the iPad slightly better for viewing approach plates, in our view.
Notice the fewer main menu icons on the Galaxy thats running Garmins Pilot mobile app? Thats because Garmins Android version of the app doesnt support synthetic vision, terrain/obstacle alerting and static maps. It wont display traffic alerts, but it will display ADS-B traffic targets. Also missing is chart annotation capability-thats where you can scribble notes and draw on a georeferenced approach chart.
