Hey Folks, I hadn't used my drones for a while and suddenly needed them last week. Took drone #1 out, opened Solex and couldn't get a camera feed to save my life. At one point I got a camera feed but there were no options to start recording or to select any options (such as frame rate, size, etc... plus the camera seemed to be stuck in photo mode..). Got out drone #2.... compass error (damn you to heck leg!!!). Got out drone #3... again... camera problems....
So this past weekend I looked at the issue again and found out that the latest android update had adjusted the screen resolution on my phone. In "balanced" mode I usually have it at Full HD (1920 * 1080), however this had been changed to 2560 * 1440. Upon switching it back to Full HD, I got full camera feed and control in Solex. Even dropping it down to 1280 x 720 I still had full camera feed and control. However anything higher than 1920 x 1080, no camera feed. Now Solex DOES have a warning that pops up about this, but I had flow before and it didn't affect anything, so not sure if something else changed besides the resolution.
I checked this out on my other drones also and was able to repeat the failure mode. So, camera feed issues? May want to check the display settings on your phone.
Just sayin...
