I have been confused for a long time by the Compass in Windows 8.

I knew that there is a API called "Compass" in Devices.Sensors, and I can use it to get the the compass reading as a magnetic-north or true-north value. You can see a sample in Microsoft help: (Compass sensor sample)!

The problem is the value is not correct at all and the value is almost ridiculous.

To get more information, I searched some apps in Windows 8 APP STORES. I found some similar compass apps, such as "Quick Compass"/"Simple Compass"/"Compass APP" The values from these apps are the same as mine. They are all not correct.

The devices I tested are Surface and Tablet2.

So I would like to get some help from you. If you ever used compass API and did some related research about Windows 8 sensors. Please give me some clues.

    What is your question? If all the other apps are failing as well that seems to be an indicator that the compass hardware is simply buggy. – Chris Jul 05 '13 at 07:08
  • I can not believe it is true. I have tried many devices, several surface and several tablet2. And try to contact the service of lenovo, he have not given me any reply. I think other reasons such as the API or other methods existed to adjust the value. – SunXiaoqiang Jul 05 '13 at 08:36
