If anyone knows of an Android device that even comes close to the responsiveness of an Apple device, I'd love to know about it.
I discovered this accidentally by taking a series of 12 shots, expecting the normal Android screen freeze and thinking "damn, the camera app is broken", then noticing that the "gallery" kept changing slightly.
This is a lot of fun with Google Photos as once the photos auto-upload, Google will usually stitch them together into a sort of gif (could be a gif for all I know, I never checked the file type). So you can still have a "movie" even in occasions where you don't have time to get the camera out and switch it to movie mode.
And software to process it. Google announced Camera2 API only on IO2014 which would dramatically improve the postprocessing, but so far it hasn't been implemented much across vendors, who had their own technology already for years. They didn't even update their own Google Camera to include, which speaks enough about seriousness of Google caring about Android for consumers.
The absolute best feature in a mobile camera is the time-to-capture. The faster it is, the faster you get the shot you want.
I'd also argue that the iPhone 5 default camera app/calibration/settings just produced better shots, faster, than the HTC One default camera.
