@marathon2422 I have a BQ M10 HD running OTA 15. It connects to my Panasonic TV with my Blackberry Playbook HDMI cable. Video playback is great, but no audio over HDMI. All you get is audio from tablet speaker. Such a shame.
it is possible to reach system settings via the battery indicator, so you can update to the latest version or change channels. Touching the "about" icon while in system settings will cause a crash.
