How did you disable "Power Genius" system app?
The disable button is greyed out in the "Power Genius" app info in my phine, only force stop is available.
Also live in Greece and I ordered from Ebay. Got the Translucent version in less than a week. At pretty good price too. It's the Taiwanese version.
When they say "will be delivered to Greece in January" I'm not sure what they mean exactly.
Sent an email asking for an update and I got the below answer . . .
". . . note that HTC U11 Plus will be delivered to Greece in January . . . "
