Hello. Anyone who has used the Galaxy S8 or S8 plus on their Mavic with the DJI go version 29/11/2017 of 4.1.18 if it flows smoothly, has errors in piloting with the S8 or S8 plus please confirm

I presume you're speaking of the video stream flowing smoothly.  I did a 10 min test flight after upgrading.  Piloting is fine and I didn't notice any video glitches.

Hi, sir. Please note that S8 is in the recommended list if you encounter problems, you can let us know. We will try hard to solve the problem.
