After low battery was reported, "Go Home" was initiated. Drone took a direct path to home, and passed over a 62' tree while flying at 60'. Two prop guards broken, but props okay. Battery was ejected. With a charged battery drone flies fine manually, but when programmed flight is attempted, app reports "No GPS lock" Top shell was removed, no unplugged or loose cables found. I tried Litchi for P2 as well as DJI Vision. Rear leg LEDs flash green slowly as they would if GPS signals are being received. App text box reports "Disconnected" with red background. Tapping text box, "Connecting" on yellow background is seen, followed by "Connected" on a grey background, not green background as expected. Of course, I suspect crash damage, but to what? Anything I can fix locally, or is it off to a repair station? Thanks for any help and/or suggestions.
