I made so much bad experience with pre-ordering, most of the time it came like 10 days later or something due to 'wheater issues' or sh.. like that.... never going to pre-order again
I have a similar issue, most of my photos are kind of blurred, even though its totally new. But i think thats more a technical issue and I probably have to get it repaired :(
I'm always using a screen protector, it just happend so many times that my screen broke and with the protector I can just changed it instead of sending my phone for repairing :/ but I was always clumsy with my stuff
