I have a P3P and Fly with a Nvidia Sheild K1 on Nougat...
I just started using Litchi a few weeks ago and Voice has never worked, not once ever and Litchi Crashes after "several minutes" of Flying also (twice today)...
Voice works fine with DJI GO but GO Crashes sooner than Litchi (usually 8-minutes)...
As per Litchi instructions, I uninstalled DJI GO when I wanted to use Litchi (and vice versa) but since Litchi lets me fly longer without crashing I haven't used GO lately...
JFYI, I first started flying a P3S with the Shield K1 Jan. 2017...
The K1 New was on Marshmallow and multiple versions of DJI GO "worked perfect" (never Crashed) but ever since the K1 did the OS Upgrade to Nougat GO Crashes, even if I'm just playing a flight log (not connected to Bird)
I posted about this on the Nvidia board (along with other people that have the same issue) and "Customer Care" asked me to send them a report from my K1 the next time DJI GO crashed...
I did that and this was they're reply, (I'm tech-NO when it come to software coding so this means nothing to me):
"We received your feedback below. Our software team investigated the DJI GO app and from the logs the native library needs to be PIE compatible.
Unfortunately this is something that the software developer will need to address through a software update:
libc : "/data/data/dji.pilot/lib/libtpnsWatchdog.so": error: only position independent executables (PIE) are supported.
