So my Galaxy S2x t989 got Jelly Bean (better late then never) and I've read about all the wonderful things that it supposedly has... but hard as i try i cannot find a user guide/faq/tutorial. for example. it says i can access the camera right from the lock screen - with a brief description of how. try as i might i can't get it to work. camera says it can do some fancy new 'ultra contrast' shots, but i've looked everywhere and i don't see any option to take it. i could give more examples, but i won't. please don't just tell me how to do those two things - i want some user guides or something.
