I only tried to connect my phone when the Tab A wouldn't cooperate, basically to rule out issues with the bird itself. I tried flying with my phone once and the processor isn't fast enough to really use - and screen is too small for my bad eyes.
I tried for 2 hours last night in my living room to connect, and it absolutely would not work. I tried the tools ap recommended in another thread, and also zapper, neither made a difference. Drive me batty. I was able to fly for half hour, 2 batteries earlier in the evening - although I did have a bit of trouble connecting, it connected after 3-4 tried both flights. Then when I got home I wanted to check some settings and logs and it just would not cooperate.
I have tried with and without airplane mode, killing as many apps as I can get it to stop, and nothing is now working. I found the nearby device scanning, and that was set to on as well - but I think that is just wifi and bluetooth connections, so I shut it off when I was doing all my trails. I am getting really close to a factory reset, but it is going to be a royal pain, as this is technically the wifes tab, and I only borrow it. She does have facebook, twitter and a couple games on it, but I don't think it is majorly overloaded.
What gets me is it working perfectly the first time I fired it up, and a few times after that, and then it seems it is getting worse and worse.
I checked, and I am running the current App, but the P3P is on the 1.8 firmware, looking like the 1.9 is out, not sure if I should upgrade just yet or not.
I know the Tab A isn't specifically supported by DJI, but darn, it should be about perfect for both the P3P and P4, I think the size is spot on, it pretty light, has GPS and a micro SD slot.
(Sorry not trying to hijack your thread Stephan, but figure our issues are common with the Tab A, not the specific bird.
