Yes, there is a fix for the explorer app, simply a matter of watching the 2nd video. Autel is working on it...it's not a problem with the monitor, has to do with Google security or something. Easy fix.
I went ahead and ordered one. I did have a Crystal Sky 5" that I had rooted and installed the explorer app on, and while it worked fine, it is old tech, old android and even though I rooted it....it is DJI tech, and still has limitations that I dislike. I will not be giving DJI anymore of my hard earned money anymore. They are an evil company, who happen to make excellent, locked down drones. (ok, enough of that)
I also have a Samsung Note 8 that I use, (bought it refurbished from Amazon....phone is perfect condition, way cheaper than buying a new one) dedicated to drone use, and that one has one of the brightest phone screens, if not the brightest. It works great too, even in direct sun....but I will give this a go and once it comes in will report back here. I will NOT be mounting it with the built in holder on the evo controller, it would make it far too front heavy to be comfortable in use, especially since I have the Alientech booster on there too. The 3d printed mount I have connects to the RC handles, has a ball joint, so you can basically use any ball joint tablet holder. Will post pictures once I get it. These tablets are back ordered, since someone there figured out that they would be great for drone use and a bunch of reviews just came out for them. I looked at them before, but they were just way too expensive to swallow. It is still expensive, but given the fact that you could drop a sim card into the tablet and use it as a phone is a bonus. The only thing missing from this beast is a video out. I think they would sell more of them if it had that. Stay tuned.
