Someone posted in another thread that theirs worked with the new version of the android app(version 1.1.0 I believe). I have a Tab 4, but i have been using my new Nvidia Shield with it. Should just forsake those silly apple products for one of those, they are simply wicked for fpv. Anyway, after the sun comes up, I'll try out the Tab 4 and let you know how well I think it works. I did try it with the app before the update and it kept crashing after about 20 seconds of connecting to my P3.
PS Amazon has Tab 4 and Nexus 7(about same tablet, but less bloat apps) for around $149, if you can wait a couple of days........
