In the Engadget video above, we can see that Nexus 5, with its quad-core 2.3GHz processor, is a very fast phone indeed: all the IU is very-very fast.
But then near the end of the 3-minute as above (2:35/3:26), they showcase the camera.
Wow. The app takes more than a second to launch. Then it takes more than a second to take each HDR picture, yet somehow the presenter comments that it takes "quick snaps".
Since when are 1s+ snaps "quick"? Will the camera be as slow in the non-HDR mode, or will it be as flaky and unusable as the post-4.0 zero-shutter-lag feature of Galaxy Nexus, which has been completely destroyed with the 4.1 update?
