Hi Guys, I recently had an issue where my Phantom 4 Pro+ seemed to just completely power off and drop to the ground mid flight. I converted my logs and there was no errors at all, just showed flying at 45km/h at 100m then nothing, even the video just stopped (after I recovered the clip that didn’t close properly) I returned it to my retailer who sent it back to DJI. DJI apparently advised they discovered some issue or error but never told me what it was. Since I have the warranty repaired drone back it is now coming up with “battery signal error” & “battery error” on the screen. Seems to still fly ok, should I be concearned about these errors?
