Quite interesting spoiler deployment on the 777 on landing. Four spoilers(2&5 on left wing, 10&13 on right wing) are completely inhibited from deployment on initial touchdown. As well, the inboard group(or at least some of them) are limited to partial initial deployment. Following a certain minimum time and reduction of AOA, the spoilers that did not deploy or only partially deployed, extend fully.
Also note that the flaperon retracts automatically as well on touchdown.
