Browsing, selecting, watching, editing Satellite channels through GUIDE selection and Settings for about 20 minutes caused TV to be almost unresponsive, each selection on channels or Android was responding after 5 seconds, channel could be selected but was without picture and sound. Cleared all apps cache to check if issue could be solved but it did not. No error appeared meanwhile. Unfortunately this has happened again in the past.

Performed a Reboot and everything was fine again.
