I took the wife's j7 and no problem so you tell me that the flagship of Samsung the S7 Edge can't be Used?
Here's the "DJI Recommend" list for the P4 Pro which came out after the S7 Edge so you'd think it would be on it, but no.

Being the flagship doesn't mean it will work well with GO. Notice the Apple iPad Pro isn't on it either which I think is their most expensive.
I did learn from the Autopilot software guys that the iPad Pro 12" runs slower than the smaller iPad Pro 9.7" model with their app so they didn't recommend the 12" Pro model although the Pro 9.7" works. My S7 Edge eventually lags video and the Samsung tablet black-screened out on me last week with GO along with some blue border when it crashed. Froze so bad I had to do a hard reboot, and it's gotten so bad it often freezes up with regards to any screen touches when even not running GO as it heats up just running normal apps. Not a Samsung enthusiast here at all as I think they have buggered up the Android OS pretty bad with bloat, and T-mobile also added their own bloatware to the Samsung S6 Edge of mine too. Awful system and I wish they'd provide these things clean and just an OS.
Even my $3K Windows notebook came with pre-installed crapware (McAfee, Norton, and Nahamic) that required me to buy Windows 10-64x and install it clean to get rid of the manufacture's added bloatware. The Norton was polling the USB ports and some of my USB devices (X-rite) refused to work with it running along with the Nahamic drivers for bass sound setup.
