The HTC One (non Google Edition) is surprisingly great. Set the camera app to:

• Shutter sound: Off
• Touch to capture: On
• Review duration: no review
• Continuous shooting: On

and you have a camera that is silent, has surprisingly fast auto-focus and takes decent photos. See my photos tagged HTC One Photo on flickr for some examples.

It blows the highlights but who cares except photo geeks :-) like me and Hub :-) ? For Normal people iPhone 4 and up, Samsung Galaxy S3 and above and now the HTC One are more than good enough. And of course the Nokia 808 is a much better camera than any of the aforementioned phones. But Nokia 808 and the new 1020 despite having the best camera sensors on the market have the least number of fun apps and normal people once the phone is good enough don't care about the best camera sensor as the sales figures of the Nokia N8, 808 and 1020 attest.
