Already tried with a second one. No luck.
LE: Even a third one, still no luck!
I tried with a SGS2 this evening and it worked instantly. With the Flyer it doesn't.
I'm thinking 2 possibilities:
1. This particular adapter does not support the Flyer, even though in the description it says it does.
2. More seriously, my Flyer has a HW problem and cannot use the MHL functionality.
So I'm going to test the 1st possibility and order another adapter. Can someone direct me to one that is 100% working with the Flyer? I'd hate to order another one that does not work. Preferably on eBay.
