This has worked in the past. The minus key was removed through an update of the Connect IQ app.
This issue should be directed towards the CIQ App (Android) section of the forum. You will have to start a discussion about the issue, but the developers that maintain the CIQ App will be able to assist/look into the issue.
Thanks.
