I also use a Samsung Tab A 7" (2017), actually moved from a 10" tab to the 7". The 10" was taking up to much real estate. The 7" using a ram mount, sits within my scan while flying IFR, were as the 10" was just big enought I had to raise it up at the top of the panel, therefore having to look up to see my charts, vs swiping right to left. With the 10" in that position, I had to take it down for taxing, which was not conveninent. I paid $125 for the 2017, it has GPS and WiFi, and work great with my Stratux unit.
The other good thing about the Samsung is it is not an apple
