Android Hardware Problems by Model

List of Android devices where we've seen inexplicable rendering problems. Is it our fault? Naw, it's probably driver bugs. But that doesn't really matter.

Samsung Galaxy Note 10
Android 4.4
User1: Areals on a vector based map just disappear.
User2: Tiles disappear from a quad image display

Samsung Galaxy Tab S2 8.0
Android 6.0.1
User1: Basemap tiles sometimes appear transparent. Random flickery shapes appear
Notes: Tracked this down to drawing a basemap and a bunch of vector data. If we draw one or the other, no problem, but both then it appears. Doing a glFlush() in between every object seems to help, but yuck.
