I am using a Galaxy Tab S7 (not Plus). The Fly app with my
M3 (v. 1.5.0) drone broke video transmission after 10 minutes of 4K video recording, but this bug disappeared with the update to v.1.5.1. The screen of the S7 is generally bright enough to use even in sunlight, at least if I can put myself between the Sun and the tablet. I'm afraid you'll need a sunshade for the S6 Lite for sunny days. Right now, I believe the S7 line is the most recent line of Samsung's tablets, but there are already leaked photos from the Tab S8 line. If you can wait a couple of months, you may get an S7 tablet for the price you'd be paying now for the S6. With my
M2P, the Tab S7 is also compatible with DJI GO, Litchi and Dronelink.
