The quality of video on P4 seems more poor than on P3, mostly on camera moving and bright scenes. Below is a sample shooted with steady P4 on the ground just tilting the camera up and down:

the mobile device is Samsung T705 with Android 5.0.

Changes in video streaming from the P4 compare with P3?
Any plans to fix the problem in SDK's codec and/or firmware ?

Hello Eagle14, did you try to kill other apps in the background? What's more, what's the transmitting channel condition at that time?

Yes, I've rebooted the device. Transmission conditions seems very good, because:
- DJI Go shows few small green dots on channels, no red ones
- The drone was in only few meters from RC
- I've tried another location 1 km away from nearest village/city

It would be better to post a screenshot of the channel condition here. Besides, do the ios devices work well?

So when you enter the Aircraft Status, what was the Radio Channel Quality at that time? If it tells you the quality is bad, you need to change another place to try again.

What does the video look like from the SD card in the aircraft? That shot only shows the result on your phone.

I've experience exactly the same thing as you on my Samsung GT-N8010. It turned out that the Samsung was grossly underpowered in the rendering department as it is pretty old. Have you tried another mobile device? I tried my ralatively cheap Sony XPeria and it worked fine. I've placed an order for the nVidia shield K1. It's a hit and miss I think so let's hope that the nVidia will play ball for me
