Im going to get this one soon after all the good reviews. I have a few question though.

1. How is the battery life if i constantly take pictures, like 500 pictures a day.

2. How is the screen like, is it easily scratchable.

3. Can i install garmin or papago in this phone?

4. Can i view .xls or .doc file ?

Im kinda new to android and this would be my 1st android phone.
