have a p3a for a month already. so far 16 flights, 2h45min in the air and 18 824m travel distance. until last flight everything alright. update to latest soft both ac an controller without problems. last flight dared to go further i.e 1+km and while being at a distance of about 300m got message that sd card is not supporting 4k recording(?????). about same time lost video and control, pushed rth and the phantom returned safely. on its way back video and control resumed so i even canceled rth and landed manually. when trying to play the recorded video on sd card got message on my tv, pc and note 3 that video is corrupt. returned the sd card in the card slot of the phantom and upon starting receive message "invalid sd card". exchanged for another sd card but same message. tried to format it in the phantom but "format failed" message comes up several times with both cards i have. tried to reinstall firmware but nothing happens since card reader do not see valid sd card. every thing else is green, imu, compass, sensors e.t.c. without issues. here link to healtydrones and the flight data - HealthyDrones.com - Innovative flight data analysis that matters before turning to dji support, any ideas what could be done would be appreciated.
