Coming from Z8/MOL2 my new Z12 Ultra behaves very different when waking up from stby. Usually I put my Z12 into stby when finished watching TV. The next day, when I power up the Z12 I get the formuler writing on the screen with the 4 jumping coloured dots and then Mol3 starts up. It's like Mol3 crashed during stby.
But not always. Now and then the Z12 is right there, showing the TV channel last watched.
