LaVike's issues don't sound typical to me either.
I've had my AT&T 830 for about 4 months. It has had minor issues here and there, but nothing what LaVike is expressing. I occasionally have to power cycle to get the MS Band to sync with my phone, but nothing that didn't occur on my Lumia 920. I don't use bluetooth for audio nearly as often. I really only use it while running. The audio will randomly cut out for a second, but again, this is the same behavior I experienced on the 920.
The strangest thing that I've come across is that the wi-fi indicator will show that I'm connected to my home router when I've been away from home for hours. The LTE data will continue to work, so I usually don't know when it's happened unless I intentionally look at the wi-fi icon. It requires power cycling the phone to be able to connect to a different router if I am near one.
Other than that, I rarely ever tried to watch Netflix on my phone, but I have been affected by that issue in the past. The camera functions just fine for my needs, but I would like for AT&T to release the latest firmware just out of principle.
I looked at Amazon's trade-in offer on this phone with Fitbit, and they are currently offering more than the sale price that I paid 4 months ago, but I can't really trade it in until I find a suitable and affordable replacement. There are lots of options, but Qi charging is a key feature that I'm looking for.
