True and sad story. My fiancee had broke lens glass in her smartphone and she can't took photo of anything. She used to taking pictures using only front camera. Weird.. but I said - no problem!
Bought the new glass at popular world wide online shop for $1. After three weeks my parcel arrived. It was today. After work I took the phone and said another serious words - It will take at least one hour and finally you'll be able to use camera again. Then shit happened. Of course I opened the phone and got to the broken part, changed it and assembled well... but the screen didn't work.
Holy fu**ing sh*t. I broke the 1,5 year old good phone. Don't know why but after searching for all connections I spotted the small crack. Not on the glass but behind it.. like on the lcd screen. But why? I was extra carefull. My fiance wasn't angry because it was pure accident. For me it was a big disaster... it was only few times in my life when instead to repair something, I completly broke it.
Fortunately she planned to buy new smartphone anyway. Small change is that now I have to pay.
