Samsung!? Yuck. Vomit. Ptui.
If you want to waste your money, go ahead and buy one. Just make sure you root it out to a basic Android OS and be careful of what other apps you load - or never load any - that may take over the processor resources and slow GO down. GO is already bloated enough as it is in processor needs.
In time, you'll be posting about "Why do I see green and magenta bands on my screen?" (Video lag.) Then they turn to gray half-screens and a bit more lag as GO grows a few months later. Then you'll get a crash where the app shuts down to black and you need to reboot the Samsung device to get GO back up and running. Months later you'll get the "Disconnected" message and nothing seen from the camera shown as both of my two Samsungs I invested over $1,200 on. Now none of mine will connect where they did a year ago.
There are sundry Android systems out there like OxygenOS (Android) and whether they run with less issues than the Samsung OS I don't know. But for me, you couldn't pay me to run a Samsung device with the DJI gear short of a bottle full of Xanax nearby for stress dealing with the device issues, crashes, or disconnects.
I should have listened to others who said "To go with the iPad Pro 9.7" if you want less issues and be done with Samsung's Android," but I held out for being cheap and it came back to bite me and my wallet badly. Keep it dedicated to the drone and do not install a lot of superfluous bloatware either. Apple seems to have more of that under control and why it runs better overall. Note that I now use an iPad
Air 2+Cellular and it is beginning to show the video lag matters as GO has grown past about version 4.0.3. Latest GO 4 is almost 1/4GB in size which is a lot for a slow handheld device, and it randomly calls out too in the background. I'll likely need to update it to an iPadPro 2 later this year I fear with GO 5 or whatever it becomes which probably will also kill off a lot of current devices.
