Hey Chintan
, No, its not that I didn't want to use the screens Camera Button, my problem was; if I held the phone right-side up (the screen's Camera Button was either on the bottom [Portrait], or on the right [Landscape] of the screen), I could not hold the phone and push the camera button with the same hand
- NOW, I realized that if I hold the phone up-side down, the camera button is on the TOP of the screen (left side when in landscape) and I can hold the phone and get to the camera button with the same hand. My revelation is: that regardless of how I held the phone (Right-side up or down, "EXTERNAL" independent camera button up/down) the pictures came out right side up in the gallery. WHOA!
If your question was with regards to the "EXTERNAL" independent camera button:
damn good question!":^) - best answer: with the method above, I feel I have a little better grip when reaching my phone through a crowd, can see more screen when using my finger, instead of my thumb, and can direct the focus with my finger, prior to taking a picture.
