I have a couple issues with my Z2600 that /i didn't have with my Z1000 Pro. 1. When I try to get the UAPP app from the Google Play Store I get a message that the app isn't compatible with my device. 2. If I switch to USB Audio everything seems to work fine but when I switch back to HDMI audio I get no volume or very low volume. Turning the Z2600 off and back on cures the problem. Any suggestions would be appreciated.
