I just bought Lenovo A859 (with Android 4.2). I notice that the camera has several capture mode, like:
 -Normal
 -HDR
 -Face Beauty
 -Panorama
 -M.A.V.
 -Auto scene detect
 -Smile shot
 -Best shot
 -EV bracket shot
 I can only use several of them since they are pretty cut and clear use. But I don't know the rest like how are they different or how they are best utilized. I've been looking on internet for sometime but can't help a good answer. Can someone please help me?
 Added (1). After several hours messing around with the camera, I think I get some of the modes, but still don't know the following:
 -HDR: I need to hold the camera steady for several seconds but I don't notice any different from the pic taken.
 -Auto Scene and Best shot: Just point and shoot, but again, I notice no difference from the pic taken.
 -Face Beauty: from the name I presume it's for taking people pics and makes them more beautiful (w/o photoshop), haven't tried it on people though…
