The Himedia Q30 seems so similar to my trusty Micca EP600 G2 -- same form factor, same ability to play most things, plus 4K to boot. It even uses the same remote control IR codes, as far as I can tell.
One feature that the Q30 lacks that the Micca had was in the Intelligent Setup menu => Function of Navigation Key , with options => Subtitle Adjustment, Search Function, Skip Playback. This affected how the right/left arrows worked while in the Media Player mode.
Any chance that the "function of navigation key" can be changed in the Q30 somewhere? I don't see it in any menu.
Can that setting be added in a future firmware?
