I have just bought 925 and this is my first lumia and wp. i found the camera very complicated. first of all i found the built in camera inferior to cam 360, smart cam and nokia camera. the pictures taken are not as clear and most importantly there is a gap of like 2 seconds when i on the screen and it takes pic but when i press the dedicated camera button it take pictures compatively fast. i am really founding hard to grasp the working of specially NOKIA CAMERA app. it is very complex. firstly when i tap on the screen a CIRCLE appears and nothing happens but when i click the photo through camera button or camera icon below it takes picture, also i turn off the flash but still flash wont stop. the front facing camera is fast of nokia camera app but rear cam is comparatively slow. i found camera 360 THE EASIEST and best to use. somebody please explain me the entire working of all apps including built in camera app and HOW can i take QUICK photos without any gap.
