Took it down to the park and did a little more testing after diner, adding power helps. Plugged into the usb port in the truck, long enough cable get away from the metal of the truck, kept RC at 100%. The tab 4 ended at 99% making it usable.
The image transmission rate is the problem. Flying at say 120 feet off the ground over the tree tops, camera level out ahead or slightly aimed down toward the ground it does real good. Aim the camera down directly at the ground or just a little to much? the video stream breaks up skips hit and miss in and out. More miss than hit and increases as the lens fills with information other than sky. Hovering still you can aim it anywhere as far out as you want, code rate is fine. Start moving forward the video fails, aim camera out toward the horizon again video feed returns to what it should be as code rate drastically decreases by comparison.
Noticed too that this afternoon a quick test here at the house, it did better with the bright sun light, sun high in the sky. Same effect to a small degree with camera angle but nothing drastic. This evening as the sun went down behind the trees it increased the issue, had trouble flying low down by the ground where the video code rate would always be high lens full of constantly moving/changing information to send back.
Really appreciate input so far and would be happy to test and or check out suggestions anyone may have to improve things. Short of buying an Ipad that is, not that I can't afford em I just can't help feel it shouldn't be necessary.
I will be sure to post outcome of test with my sons Mavic pro platinum, his controller and drone using my tab4.
He can fly his just about to the town down the road from the park and back, little better than a 5 mile round trip. I couldn't come near that with this one. Little over a mile and the live stream dies out too choppy to continue, full control over drone but no video to fly by. And while flying great distances isn't my main goal I'd like it to perform as it should, and in the space around me I intend to operate within.
And yes for full disclosure my son uses a iphone 8, a young man yet and with really good eyesight....me no not so much anymore on that front. Reason for the larger screen and it's intended use, a little phone screen by comparison is just to small to be of much use to me. Point being while it works better with my phone I'm not interested in operating it that way. That and my phone is loaded with apps and based on what I've read exactly why it shouldn't work or work very well.
I said it before I'll say it one more time, this lenovo tab4 8 works great with the Dji P4 so I didn't think for a second it'd be a problem with this one both use the same app. So much for that
