Randomly the screen on my Nexus 7 2013 tablet will randomly suddenly freeze and go black and white during flights. I get a "Transmission Lost" message. When this happens, I do not lose control of the copter: I have a record of this when it happened twice during the same flight yesterday (see edited vid). In both cases, I did not engage RTH. The first time, I simply backed up and the transmission was restored. The second time it happened the copter was much closer. That second time, I still had control and visual contact too, so I let it hover up there. The wifi seemed connected, and I still had control, but I could not get the image back. So I closed the djigo app and re-opened it.and viola, back in business. WTF is going on? Is it the tablet? It seems like the controller and copter are fine- I can usually get to 2,000 to 2,500 feet with the factory set-up which seems about right.
