Issue with Polycom Trio 8500 (see image)

Hi there!

I was wondering if anyone has encountered this problem. After updating to the latest OS, the UI breaks. The only button that works is the settings gear on the top left, and the volume control. I've tried resetting to factory settings which does bring back a functioning UI, but it auto-updates within 2 minutes and comes right back to this.

Can anyone help shed some light on the issue, or know of a possible fix? Thanks!
