Hi all, this is my first post. I bought my PS-SE back in June and the manual etc was in Chinese as it wasn't released outside China yet. It still worked great and is stable but there is lagging about 4-5 seconds between camera and my screen. I used a Samsung Galaxy phone and had the problem so I bought a tablet with 2gb Ram and wifi/gps etc.. and only have the DJI Go App and DroneLogbook Apps on it and still the lag. I've calibrated everything and gone through as many settings as I know including lowering from 4k to 1080P on camera plus buying a SanDisk Elite Ultra 100mbps SD card. I even cleaned the cable going into gimble and switched off the video cache log and problem remains. The film taken is perfect with no lag it's just I have to fly within line of sight and be careful. The lag/delay is there when it's close or far from transmitter. It's headwrecking to be honest as I can't figure out what to do. Any idea's people?
