Windows 10 UAP - Compass.GetDefault() is sometimes null

Working on a windows 10 UAP and need Compass data. Has been working most the time, but every now and again Compass.GetDefault() returns null and it'll keeps doing it till I reset the device.

Thought it was my device at first, but it is randomly hitting the issue when submitting to the store and failing as a result.

Any suggestions would be great. Thanks

The issue i'm hitting in a phone, which I don't belive has the connected standby issue (if it does, how would I check). The phones tested have been a Lumia 930 & 630 which both have a compass built in. Any suggestions would be great. Thanks.

Hi null value will be returned if the specified sensor is not available in the system.
When a system is in Connected Standby mode or sleep mode ,the GetDefault method will return immediately with a null result.
so check system mode before call this method
