I got a case off amazon, think it was moko, at any rate it has a trifold flap screen cover that doubles as stand. it is a nice slim and effective case but I find that the magnets it used to keep the flap closed and to hold the folded flap behind tablet when being as a stand mess with the primes internal compass, and it does not point north. while I'm not certain of anything, I also worry that the magnets could, perhaps in combination with the aluminum backing, interfere with GPS or wifi. tho I haven't notice wifi performance drop yet, I haven't really test anything enough to say for sure

at any rate, I would like to remove all worries by finding a similarly styled case that doesn't use magnets. anyone know of such a case?
