@XVortex As you're the true xDuoo's development reference (way ahead than the xDuoo software team itself, unfortunetly), I like to share with you some GUI flaws related to the album covers in the original firmware that I think should be addressed in order to make the user interface more polished and consistent. I really hope xDuoo takes note of this as well, because is their own responsability. The reference model is my X20, but I think it applies to the X3II too (due to the same screen resolution). Like you pointed before, the screen resolution of these devices is 240 pixels (horizontal) x 320 pixels (vertical). Well, I figured out that putting a pefectly squared and normal cover image of 240x240 pixels (or 480x480, 720x720, etc.) causes an ugly magnification that totally ruins the image quality and it's overexposed with the reproduction bar in the playing menu, as I show here: But at least it displays the main menu thumbnail correctly: So, playing and experimenting with diferent crops and resolutions, I decided to "mod" my albums' images in order to get the full cover displayed in the playing screen and let the reproduction bar clear. I found that the perfect result was a 240x320 pixels image with the cover image positioned at the top above, a 235 pixels of height adjustment (ruining the aspect ratio a little bit, but with much better visual result) and finally filling the remaining bottom part of the image in black color. The result is explained in the next image: Sadly, aside for the minor flaws with the corrected album image (basically the 240x235 px distored aspect ratio to make everything else fit and look ok), now the main menu thumbnail completely ruins out: As you can see, I fix the cover image display in the play menu, but then it ruins out in the main menu thumbnail. Do you think something can be done or ultimately address the design suggestions and flaws directly to xDuoo so they're aware? I really like to contribute making the original firmware better, but with my unexisting programing skills I don't know if there's something I can help you with, albeit I'm good at designing and editing this kind of stuff (skins for music players and so on). Please tell me if if I can help you or do something useful with this information.
