Hello everyone, i've recently upgraded my Shield K1 to Marshmallow from Lollipop. The compass on the Shield is now almost non-functional, i have the "Field compass" app which does seem to calibrate the compass once i wave the tablet round in a figure of eight but the compass is still not working in the Go app, the radar is way out. The Shield was perfect on Lollipop so does anyone know how to downgrade the shield from marshmallow back to lollpop? Or is there a better compass app that does the trick? P3P running on latest firmware and flies perfectly otherwise. Go App 2.7.1 P3P Firmware 1.7.60 RC 1.5.80 Shield K1, android 6.0 marshmallow.
