USually the landing gear auto retracts and auto extends based on height but recently it has started auto retracting and extending randomly mid flight.

Anyone know of anything like this happening?

Hello, what is the height when the drone starts retracting and extending the landing gear automatically?

What firmware do you have installed? Firmware 01.09.01.30 fixes some issues that sounds (but might not be), like your problems. Check firmware version and report back here.

Check for dirt/debris in the sensors, most likely culprit.
