There is a private bug list which HiMedia are working through, but no probs if you want to maintain a public one here.
-Auto frame rate switching (23.976) works for 4K and 1080p, but not for resolutions below 1080p. HiMedia are aware of this.
-A screensaver would be nice and can be added to Kodi through add-ons if you use Kodi.
-No wrapper support for Samba password protected shares is a longstanding problem and is related to security features in Android. It's going to be difficult to solve.
-HDR will be fixed soon.
-Resuming videos definitely works here in Kodi+wrapper from Samba share.
-HiMedia are aware of SACD not working and are working to implement it.
-HDMI-CEC should be fixable. It's implemented in the chipset.
- The Google Play Store crashing problem only happen immediately after firmware install before Play Store has a chance to update itself. Hopefully not a problem on future firmware but not a big problem now since it fixes itself on first run of Play Store.
-TV Mode 24p not display correct info is noted and has been passed to HiMedia.
-Please reinstall firmware instead of doing a factory reset. The factory reset will reset the box with some HiMedia apps missing. It is likely to cause problems.
