I am so so so greateful for all your answers and I am finally starting to feel better

I am really sorry for my dumb questions but I just left my Nokia 5800 that I used for like 4 years and this is the first apple product I ever bought (in Bulgaria they are not popular so I don't have someone to consult

).
Tomorrow I am going for a trip and after that to a pool so I will make lots of pictures and try to play with the light, because most of the time I am taking pictures agains light sources (street lamps,the sun,club lights and etc...)

I have another question for you.I am idealist and pedantic.When I bought my phone I noticed a little scratch on the left side but decided not to ask for another phone because the there was no more white ones available and the guy unboxed it in front of me so it wasn't his fault too.I put the phone in a *speck case and protector.Before few days I noticed a 2 tiny scratches on the camera visibale at light and special angle.I am sure I didnt caused it because I am babying this phone - i dont even put it in my pocket so something wont scratch it.This is the reason I started making those pictures around (and I freaked out with that light source thing).I don't know why,but I think everyone's cameras doesnt have scratches,like my phone is the only one with scratches on the camera and that thought makes me feel very disappointed.Probably because I didn't cause the scratch,because I believe the quality of the pictures is ruined(it may be with 2% but it could of been better)...Even now that you tell me this light source thing is normal and I believe you,I still continue asking myself what if there were no scratches?At first I was thinking to ask for replacement,but I am not sure if the scratches are on the outside or the inside of the camera.If they are outside even though I didnt caused them I cant prove them and I wont get another phone(and I am not sure how I would feel about changing it because I love my phone already and it's like giving piece of me,but the scratches makes me looking at the phone with another eyes).However the authorized service (because we dont have apple store) is far from me and I will have to travel half of the country just so they can check it and if they refuse to change it...would be a total waste of time,money and nerves.So I want to ask you - Are your cameras having scratches too?Please be honest :straight-face:
Also I want to ask you something about the sound on the iPhone.I played Lana Del Rey's music video called "young and beautiful" thru her vevo's youtube chanel(vevo is having great quality of sound and video) and I found interesting that the sound is fading and going low on thе "strongest" parts of the song.I downloaded her album thru iTunes and it's happening the same thing.The faiding is really annoying.I dont experience this kind of problems with the earbuds.I know this is a phone not a stereo, but is this fading normal?
I am really greatefull for all your answers and I am thanking you in advance again
P.S. Other then that I think that the phone is amazing and I start to believe that Apple is the best thing that ever happened to humanity
