I am using the same tablet from my phantom 3 Pro. A Samsung Galaxy Tab 4 8.0 LTE  with my Mavic. I have installed the Go 4 App. I have used it with no problems for about 2 weeks. I have used the Active track with no problems, When I use the  Point of Interest (POI) mode , I can do the setup to select the height and radius and speed . When I tell it to start it gives me a conection error and about 1 second later the app crashes and the restarts. I have tried this a few different times with the same results. Has any one else had this problem???

I have EXACTLY the same problem. Let me do the setup and crashed when I hit start. It however worked on the 3rd or 4th try for me. Never tried it after that. I was using it on a Samsung S7

Hello, could you please make a short video of this issue?
Besides, please find the crash log and post it here. I'll help to pass it to our engineers for review. Here is the path to find the crash log: mobile device/SD card/DJI/dji.pilot/LOG/CRASH

I think everybody (with android OS?) is having this problem.  I crashed on me every time I tried it.  In Go3, however, it works fine.

I think I saw the same when trying Course Lock. Not sure though - will test again soon.

Hi, I am also having issues with the intelligent flight modes. I connect my Samsung S6 to the RC controller and while in flight the DJI 4 app would crash. Is the crash log in the SD card? I checked my phone and there is a similar path but the last crash was 3 weeks ago while my crash happened yesterday (Dec 18 2016). I can't check my SD card since I reformatted it due to running out of space.

Same here using an S6 Edge and go 4. Two reboots and I got control back but I won't be using go 4 again until the next upgrade. This happenned using poi also. It looks like a programming issue so I won't bother sending in a log.

I uninstalled the original version thinking it won't support the Mavic anymore. Are you guys successfully using the old app?
