yes i know you are all waiting, i had to go to the usps center to get it. first thing i checked was the speaker. and it is true all cells have static sound but the popping sound is what was defective, this one doesnt have it but the screen is yellow! the white have a yellow tint and when i put both devices side to side it really shows off the difference. the lumia 1520.1 have a yellow tint to it. the 1520.3 is perfectly white.
soo yes i am retuning the 6th device and it is my last so no more updates of that matter. but i will post pics and comparisons if anyone wants to.
