No, flying it straight from my Moto G Power2021 phone. Just installed the app today and got it working. I used to run it on my old Iphone 6, but the app keeps shutting itself down. I guess I need to invest in a controller, or a new drone. (not a Yuneec)Do you have the Breeze Controller (Bluetooth)? It does speed things up for Android. Not sure why the video feed is so laggy without using the controller other than it has to read the virtual sticks on the screen.
On my Fire7 tablet there is about 2 seconds lag without using the controller, and another 300 to 500 milliseconds when using the controller. Definitely not an FPV drone even as slow as it flies.
