I've been using Windows phone since the day before the HD7 was initially released on T Mobile some four years ago. Despite hiccups I've been pretty loyal to Windows phone and am still so. I have my 1520 that I absolutely adore and couldn't imagine doing back to my garbage M8 or my so-so 5s. This phone is perfect. My 920 before this was also a remarkable device. Likely the best built device I've ever had with proper wireless charging and absolutely smooth. That said, it's predecessor is absolute junk. I've not seen a phone drive more fans of a product away in the mobile world... Well... Ever. First, I've handled 6 of these and literally every one I've had had either a yellow or people tint or an awful gradient either vertical or horizontal. Next, 5/6 of those had the creaky back issue that I thought we left behind with the original 900. Oh, did I mention the subpart sound quality? It's absolutely appalling to hear this phone and my 1520 side by side playing the same song. One crackles, the other is my 1520. It almost feels like the people at Nokia realized they were about to get laid off and just decided to sabotage the company. I hate seeing long time fans turn and run because of this thing. It's so sad because aesthetically, it's a flawless device but pretty much everything else is wrong with it. Hell... Just scrolling around with this next to my 1520, it's embarrassing what the speed differences are... If I can suggest anything, don't touch this phone with a ten foot pole.
