[Nexus 4 Q&A, Help & Troubleshooting] megapixle:
I know there have already been a million reviews of this device, but in case anybody wants a million and one, here's my 2 cents. If not, carry on.

This is my first Nexus device, coming from SGS2 and before that the original HTC EVO. I'm on T-Mobile USA.

After one week with the Nexus 4 my verdict so far is: good with potential to become great. Here are a few quick thoughts in pro/con format:

PROS:

- Super fast and fluid, I've noticed no lag whatsoever. Haven't played any 3D games yet though

- The N4 is definitely a sexy device and feels great in the hand

- I do like the smoothness of the glass and the curved screen edges.

- Painless unlocking / rooting

- Best phone for the price, by far

- Love having a notification light again, hallelujah

CONS:

- Have to say I am a little disappointed in the screen. It's not terrible but I guess I've been spoiled by the saturated screen of my SGS2. The N4 was just.....underwhelming. Sharpness is fine but the first thing I noticed is how dull the colors seemed compared to my SGS2. I'm sure I'll get used to it but I'm not able to call it an "upgrade".

- Surprised at the bugginess of Jelly Bean, I'd say I get one random reboot per day, maybe two. There are also other random oddities such as the bluetooth toggle not working properly, force closes, etc.

- I've had trouble with connectivity/connection speeds on both WiFi and cellular data, if I can't get them resolved it may end up being a dealbreaker.

- Battery is....meh so far. I've done all the recommended tips of disabling/removing this & that, and I generally make it through my day of low to moderate usage, barely. I have yet to have screen time of more than 2-2.5 hours. If I upped my usage by even just a bit I'd need a top-off during the day.

- The device seems quick to warm up. Even when I'm doing something like light web browsing it's surprising to feel the device warm up in my hands.

- Gotta admit there are a couple of niceties I miss about Touchwiz such as the quick toggles in the notification drop down.

- Given the numerous reports of glass breakage / scratches makes me super careful about handling my headset. Almost paranoid, really. Luckily I have no visible wear so far but it would be nice to not have to worry so much about this. I do like my phones naked though so I'm probably asking for trouble.

- Some of my apps are buggy with 4.2, guess that's the price you pay for being on the cutting edge.

- Ringer / notifications are really, really, really quiet when the phone is laying flat on my desk.

- I'm not a huge fan of the growing amount of "Google Bloatware". One reason I like having a Nexus device is to not have to deal with all the carrier installed apps / services. But I dislike having to disable Google Magazines, Google Plus, location stuff, Google Talk, etc. etc. Maybe if the battery was at least up to the task of supporting all these things I wouldn't mind as much.

Admittedly most of the above "gripes" are minor, but it's surprising because on my old SGS2 I didn't really have any gripes at all. If I can clean up a few of the above items I'll be very, very happy. Overall I think I'll like the N4 better than my SGS2, but it's far from the landslide I thought it would be.
