I recently had trouble with my Nexus 7 2013 showing half screen video. I downgraded firmware and fixed that. So today I try to fly and tablet won't connect. Controller was connected and displaying info but not tablet. I hooked my S7 up and presto it was fine. I restarted app like 4 times and nothing on tablet. I've taken all the steps in DJI page to help speed up tablet but I really don't think this is that kind of issue.. There is just a black screen that says disconnected. I haven't updated firmware and it was fine a week ago. Really good connection and nearly zero lag. My tablet shows charging when plugged in to controller but it's like no data is getting through.
