In my line of work camera happened to be important, low light shots as well. I do a lot of surveys (networking) that require taking the snaps of ducts, risers, suspended ceilings etc - you get the gist. Light in those places is never good... So one of the most important elements of the phone is camera and possibility of making quick notes, emails etc. Key2 was my weapon of choice but now I am not sure anymore...

well the good and convenient thing that i like about the KEYone camera app is, although the low-light may not be very good, you can still adjust the exposure of the shot by swiping on the keyboard to make it bright enough to see everything. The quality of the photo won't be there, but at least you'll be able to see everything.. i take it how nice the photo looks is less important for your job, and more so the ability to see everything to make an accurate assessmentI, myself, use my phone for instagram at times.. lol
