This day I new P4Pro received and the first test flight led to problems. HTC Nexus 9 "I used always worked fine with P3P, not with P4Pro.
Rremoved my" old "GO app and installed GO4 since 4 models. Everything is ok after take off, all ok for photo shooting, but immediately when recording of video, screen freezes up, shivering.

No help, even switch RC off, quit GO app, RC on, running up GO. A RTH had to be carried out, landing manually, as usual otherwise.

A firmware upgrade of the craft must be performed I read on the monitor screen. Should such an upgrade might be required for such a mistake? I wonder.
