The 920 is probably my worst smart phone ever. Have the white 920 on At&t. In 8 months I'm on my 4 replacement, and was ready for my 5th yesterday after it bricked...AGAIN. But, after waiting for several hours, and then while talking with warranty replacement on the phone, I tried one last hard boot, and it came up.
Bluetooth only connects to my vehicles if I turn the car on, then reboot phone. People can never hear me (all 4 replacements were the same, so it's not a fluke). My guess is most people rarely use the phone for actual phone - I rarely do as well, but when I do, the person on the other end just rips on me and my Windows Phone on how crappy the quality is. I used iOS for years, and never really liked being an Apple user, but was a jailbreaker, and then it fit my needs and was a very critical tool. I bought and iPhone 5 a week before the 920's came out, then sold it and got the Lumia right away. Biggest mistake I ever made. It's a solid piece of hardware, and has a camera that only the new 1020 can beat. Windows Phone 8 is really poor and years behind.
I wish Microsoft would just scrap the platform, and buy into iOS and get all their apps and integration on iOS or Android. Most anyone I know that went from iOS to Windows Phone 8, have gone back eventually. It seems just the Android users and previous Windows 7.x users have joined to WP8 forces, and have really loved the new Lumia's and HTC phones. Which tells you how bad WP7 has been, and Android (never used Android, so I can't criticize very much). I used to be a big Windows Mobile 3.1 person back in the day as well before going to iOS. It was the hardest thing for me to do. As an IT Pro, I need constant mobile communication and it needs to be efficient and easy and reliable. Unless I reset the phone every month or so, the battery life eventually crushes the phone in 5-6 hours with no use at all. After a reset and all the same apps and settings installed? Anywhere from 16-24 hours life, and usually reports 1+ days remaining. Windows Phone 8 can't do it, and is light years behind iOS. I have a couple weeks before I have a family plan line eligible for upgrade, and will be heading back to iOS, and doubt I will ever hold a Windows Phone again.
I really think it's impossible to get 4 devices of all the same spec in 8 months time, and attribute it to just bad luck. No one has that kind of luck, bad or good. I want to love it and want it to be a good phone, but I'm just making too many sacrifices and not being able to have a functional device that I can trust, day in and day out.
Nokia has alway been a favorite of mine, and between them and Motorola, always had the best hardware, it's jut too bad Microsoft has brought Nokia to it's knees.
