I had been using my Rossini through phone app all along. Only recently I when I turn the volume dial, I realise no matter which direction, it only reacts anti-clockwise! which means turn the volume down.
Then I test the menus using the dial and the same thing happen (only rotates one direction!).
Also recently I realize the display has display has the vertical line that many user also occurs.
Is it common to have these faulty parts? because I have very rarely press the buttons and dial on the machine, and kept the display off as I want to keep it new, but all this issues happen. Could it be something with the software bug ?
