title: Definitive Fix for Android's bug of duplicating photo on gallery when using the internal camera
body: <p>This is definitive fix for the Android's problem of duplicating a photo. Tested it on 2.3 (which has the bug), 4.x (which doesnt have the bug) and 5.x (which has the bug too). </p>
  
  <p>The problem is that the photo is saved in two formats: usually one is the timestamp.jpg, and the other one is the full_date_and_time.jpg; sometimes in the same folder, sometimes in different folders. For example, "1430910805600.jpg" and "2015-05-06 11.14.00.jpg". Worstly, one cannot be converted to the other.</p>
