So I went out this evening to fly and everything seemed just fine. Launched fine, flew out for a while and all was well, then my video was frozen and I couldn't see what was happening - then the app crashed/nexus 7 (2013) automatically restarted. Thankfully I was able to bring it back by eye, and it responded to the remote perfectly fine. Flew it again after that without problem. Then I switched the battery and it wanted me to recalibrate (do the dance), which I did. I then noticed it seemed to not want to lock on GPS (hovering around 15-16 with low bars), and I tried moving it a few times to avoid potential interference. Eventually it did get it and I took off as I normally do - but it just flew away! It was right over water and my heart was pounding, but thankfully I was able to bring it back in and landed it. During the return where I was "overpowering the wonkiness" it did seem to regain "control" and I was able to bring it in smoothly (but I feared it'd go crazy again at any second). What the hell happened!? Not a good night for my faith in DJI .
