I have a 6+ and have had 10 flights with it and no problems.....until the other day. I was 10 minutes in to flying around soccer fields all systems were normal. I was watching the P3 as I circled around some flags, looked back to pilot and screen was frozen and disconnected. No audio warning, still in control, flew back and landed with no problem. I could not exit the screen or app, all frozen. Had to completely power down phone to get out. I have flown twice in since and no problems. So no answers for you just some understanding. Here's to VLOS flying.
