I've just did the update to my Samsung tablet (sm-t230u) and now the app will not open. Message says 'Unfortunately,DJI GO 4 stopped', I've sent a report but looking for help. Thanks

Best advise is to ditch the Samsung and get an iPad or you will forever have problems.  Its just not going to work.

power off tablet and reboot. if it doesn't work, delete app and download app again. good luck.

Many people have issues with Samsung products and DJI quads. Also, there are a significant number of people who have issues with Android 7 and DJI Go 4. I am not sure there is a sure solution to either. You may very well need to look at another mobile device, whether a recent-generation Apple product or a recent, POWERFUL Android-based product that is running Android 6 or earlier.

Thanks for the feedback, sound like I should have just purchased another P4P+ and been done with that problem.
