Support F3 and non-stock camera app

view story

http://androidforums.com – This is kind of a weird issue with my phone. I installed other camera apps ( 4.3 Gallery/Camera, and Camera Zoom fx) and i get a very grainy camera viewer. The stock camera looks clear while non-stock apps are grainy looking. However the pictures come out the same... Im wondering if this is an issue only with my F3 or is this a "bug".. (the photos are reduced size but you can still see what i mean) Attached Images 2013-09-06-18-03-28.jpg (334.6 KB) IMG_20130906_180318.jpg (131.3 KB) (General)
