- Added: A new setting "Setup / Misc / Start & Exit / Auto start Dune HD Media Center". Can be used to start Dune HD media center automatically when the box boots. Note: it does not start immediately, it may take a few seconds (depending on how many apps are installed in Android TV).
- Fixed: In ATV12 firmware, in Premier 4K Pro model, the front panel display could become not working after reboot and in some other cases; the system could show requests to give permissions to access the hardware.
- Fixed: In ATV12 firmware, information about HDR video mode in Info window could be wrong when using TV-Led DV.
- Fixed: In ATV12 firmware, the use of Auto Resolution could cause a crash. Now
Auto Resolution in ATV12 firmware can only switch between 4K and 1080p, and
between 480p and 576p. This is because ATV12 firmware changes screen
density on switching between other resolutions, and Dune HD Media Center
doees not support screen density changing.
- Fixed: Installation of apk/plugin/skins from network shares was broken in the previous version.
Version 240412_0210:
