Love my Shield to bits, apart from the incredibly flakey compass. I'm running with 5.1 lollipop which doesn't make the compass completely non functional like 6.0 does. However, the compass is unbelievably skittish which is a major annoyance. Apparently the reason for this is that the K1 has bloody great magnets hidden away in the case for their proprietary magnetic cover. These magnets are not shielded (you can stick the shield to a fridge!). Might have to live with it, but don't suppose anyone has a solution?
