Aloha,
The nVidia Shield K1 is having problems with app crashes. Android, nVidia and DJI are working hard to try to solve the problem. From the front line though, it is beginning to look like the strong magnet built into the back of the nVidia Shield K1 may be a major part of the problem. I am currently up-to-date with Nougat 7 and nVidia Shield K1 5.1 as well as all the DJI firmware and apps. My crashes only happen when I take my parabolics off the antennae or some other scenario where the strong magnetic field can get to the antennae. That is why I am working on a shielding solution. Someone on another thread mentioned that shielding the nVidia Shield K1 with aluminum foil helped with a related problem. Suddenly the light came on and I realized that my parabolics were acting in a similar capacity as the proposed aluminum foil shielding.
Now, I will be trying the aliminum foil shielding to see if it helps. With this approach, I can test with and without the parabolics and aluminum foil shield to see the result with the app crashes. There is almost no cost to this effort. With just the parabolics, my system is really very stable. Crashes almost never happen anymore and now that it all makes sense, I may be able to improve on even that performance. That will be a big relief!
The problem is that the nVidia Shield K1 is designed and built as a gaming tablet. With the magnet, the tablet can be placed on a metal surface for stability while gaming. But, it is also used for flying. The flying technology is getting so sensitive that the magnetic field is beginning to interfere with the newly more sensitive antennas. This causes the app crashes in my theory.
Also according to this theory, the only way to stop the app crashes is to make the antennas less sensitive (others are rolling back software), unless you remove the magnet or shield the magnet. Making the antennae less sensitive brings back some of the other problems that were solved by the DJI app and firmware improvements. This is also the case with nVidia and the Android OS upgrade to Nougat. Going backward is not the solution. It can be a temporary solution to get you up in the air, but it is not a permanent solution. We need to keep the more sensitive antennas and get rid of the magnetic interference.
One solution is for nVidia to make Shield versions without the magnetic back and sell them as flying tablets. This could even cut costs for nVidia. Until then shielding the nVidia Shield K1 magnetic back from the antennas with parabolics and / or aluminum foil allows the latest firmware, software and apps to make the antennas more sensitive and still keep the app from crashing. At least that is what is hoped for!
Aloha and Drone On!
