I too unlocked it right away, but have yet to root. I will be getting to that soon, though.
Hardware:
It is a beautifully made phone, but it's big. That said, every time I pick up the N4 or the S3 (wife's phone) they seem tiny. Not going back.
Everything is tight and smooth with no defects or reports of them. I'm not crazy about the position of the power switch and the volume rocker. I would have preferred them a little higher up on the phone. Maybe that's just what I'm used to. The phone is very slick, and not in a good way. The glass on the N4 was an adjustment, but I was able to adapt. This phone is the first phone I've ever felt necessary to put in a case just for the grip and slip potential. And, without a case, the back is a fingerprint magnet for a swarthy male of Mediterranean descent. Must be all that olive oil.
I've taken a few pictures with the camera and they blow away the N4, but then again, the N4's camera was not that great to begin with. I have read all the comparisons to the S5 and the iP6 and most of the test shots on the S5 pop, but I've come not to trust Samsung's "enhancements" that over saturate and over contrast images to make them more vibrant. I'd rather shoot raw and do my own adjustments, TYVM.
As stated before call quality, signal strength and wifi are all rock solid. I keep WiFi and Bluetooth on all the time so i don't know about WiFi reporting battery use even when off. Speaking of battery life, so far it's stellar! My average day ends with 60%+ still available.
Software:
Lollipop is bright and fluid. I'm still finding things I love about it. Lock screen notifications are such an improvement, it's worth the update just for that! I haven't had any locks, reboots or glitches that i'm aware of. So far all of my apps have worked without issue (except the root apps, obviously).
Now, I love that the Gmail app now supports IMAP and POP3 accounts, but I thought it was pretty presumptuous of Google to include an "email" app that turns out to be nothing but a notice to set up your accounts in Gmail. They just took away the gallery without warning, so why not the email app, too? Not that I am missing either one, it's just inconsistent.
Accessories:
Of course nothing fit any more.
I used the turbocharger and charge times are stupid fast. That's handy if you need a quick power boost, or you forget to charge, but my use doesn't really make that an issue. I bought a Qi-infinity charger and found something quite interesting. I plugged it in and first the charge light flickered a little and the phone didn't record charging. A bit of shifting and adjusting of the phone and I could find a sweet spot, but it was as if a sneeze would mess it up. Then i check the charger it was plugged into and discovered it was a Samsung unit (I think for my S2) and remembered that when I plugged my Note 10.1 into that charger, it wouldn't charge, so I tried the Note 10.1 charger with the Qi-infinity. Boom, charging in pretty much any position.
The difference was that the Note 10.1 charger put out a full amp while the S2 only put out .7 amps. I found a generic USB charger in a drawer that was rated at 1.0 amp out and there you go, Bob's your Uncle, Yatzee!, etc.
I also replaced the iOttie car dock with the iOttie-XL. I love these things, but the side grips grab the N6 right over the volume rocker.
I'm going to wait until i have the case on before I start fussing with it.
I don't know that I'd call the Moto 360 an accessory, but I've been rocking one for 2 days and am loving it. The notification might be a bit much, but I've got them all on right now. It's nice to know there are Russian women who want to know me right in the middle of a meeting.
I did see that. Honestly, I haven't tried it again since the initial use. I used my TYLT charger at home last night. I will try it again today and report back. There was a VERY loud hum and high pitched squeal when it was in use. It was sort of pulsing on and off with the high pitch squeal and hum. It wasn't constant.
FYI, my charger is dead quiet, too. You might see if they will replace just that part.
