Hello & Welcome to Just Answer,
Sorry I didn't see your question earlier and to hear of any issue you are having with your device.
To help you with this issue, may I ask:
1) The AGE of the device?
2) WHEN this issue first began - or was noticed?
3) Is the device inside a vehicle that is parked or moving - when this is noticed?
4) Are there any tall buildings or perhaps trees around - when this is noticed?
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved?
I look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
