The phones with the best / most accurate compass sensor

[windranger]

I want to write an Android app which relies heavily on the phone's compass.

I'm looking for a phone with a compass sensor as accurate as possible and low latency/inertia.

Are there any reports on comparisons between different phone models or makers..?

From what I've searched HTC, LG and Huawei phones seem to be good as far as the compass is regarded; HTC uses Asahi Kasei's sensors.
I could find more complaints about Sony's Xperia.

I'm thinking of choosing from HTC, LG, Huawei, Galaxy, ZTE, maybe Xperia but I'd like to know some legitimate opinions first.

Thanks.

I’ll move this to General Help & How To if okay with you. PM me if not.

Since the sensor is most likely a Hall-effect sensor on all phones, there's no inertia. But bringing the phone near anything ferrous, even wearing it on your belt a foot from a small buckle, is enough to render it useless until you calibrate it again. (Three turns in each of the three planes.) No electronic compass is going to maintain accuracy when you move it around the real world, where it comes into many varying magnetic fields.
