Well I got my Nexus One back today and it is working fine, although the work they did leaves some to be desired. Here's how the final result came out:
I'll start with the negatives. I notice now that the auto brightness feature works terribly compared to how it used to, so I'm guessing that the light sensor may have been corrupted a bit. The color of the screen is off... it's not as colorful and vibrant as it used to be. There is a strand of dust stuck inside the screen now, there's a scratch on the back of the phone on the bottom half where the bezel meets the soft matte material and on the upper half of the back of the phone there are some markings on it that I have been trying to wipe off.
On the bright side, the LCD is fixed!
And they may have (maybe?) fixed my power button? It's not a service I see on there site but before I sent my phone in my power button was about almost broken. I would have to click it really hard to make it work and even then it would take a lot of tries before it worked. Now today I clicked it twice (not really hard) and it worked both times. Well I only use it to turn on my phone in the event it happens to turn off but if they fixed the button then that is a bonus to me! ^^
Edit: Wow.. now the phone speaker is complete garbage. I can barely hear anything from it, almost missed my alarm clock today because it is so messed up. Honestly, I could've dealt with all the other problems, but this is just a big 1. I don't think this company will be getting any business from me in the future...
