Hi Guys.
I got a trouble with my phantom 3 professional with latest firmware (and app latest version) at December 10 2016.
Videolink goes down I get the App message "no image trasmission rth return to home?".
I had testing some condition:
Tablet 7" Huawey Mediapad T1
camera SD card mount
The videolink goes down from 30 seconds to 2 minutes from Phantom power on (or after record start).
I tried to set PAL/NTSC and all resolution available but no change happens (after camera reset videolink goes up but after 30/40 seconds videolink goes down again).
NOTES: if I remove sd card (and power on Phantom) videolink stand up always.
------------
I tried also to use Samsung Galaxy S5 and it wors fine always (with and without SD card).
