Unknown Error Icon on Q5

Yes, I have searched through forums for solution but most link recommended are either broken or obsolete.
My Q5 is showing 'unknown error' by the top right side. The OS is currently 10.2.1.3247 and the radio version is 10.2.1.3140.
Please I need a prompt solution to this. I'd be so grateful,
Thanks

Your phone is showing this error on the home screen???
