[Nexus 6  General] Bill720:
Perhaps it was just interesting timing that my previous secondary phone (the HTC One) died when it did, but whatever the reason was, I ended up picking up a used Nexus 6 a few weeks ago to serve as a combination backup and secondary phone. When the battery in my daily driver, the Moto X Pure Edition, took a crap last week, the "backup" side of that purpose was put to the test. Here's how it went:

XDA Stuff: Unlocking the bootloader, obtaining root, and installing the Xposed Framework (along with MinMinGuad and GravityBox) & A.R.I.S.E. audio was extremely painless. You'd be hard pressed to find too many other newer Verizon-compatible devices that are this easy to get started with that stuff on.

Device's casing: For having a screen that is only .26" larger, this phone sure is a lot wider than the Moto X Pure Edition. It's also extremely slippery. I'm surprised these things last as long as they do among folks with "normal-sized" hands. Anything much wider than 3" is a recipe for droppage. Thankfully, I got it with one of those giant super-grip kickstand casings. While this improves the grip dramatically, it makes the device extremely cumbersome to pocket. The kickstand comes in handy all the time though. It's sad that this monstrosity covers up the loud-and-proud NEXUS badge on the back though. It's kind of like hiding the Verizon logo; you just don't do it. :)

Screen: Easily the Nexus 6's biggest weakness. Aside from Samsung, Motorola seemed to be one of the biggest proponents of Oled panels during the days of the Nexus 6 (and even before). I'm probably in the minority with this opinion, but the Pure Edition's LCD really spoiled me, so the Nexus 6's panel was a letdown. Not only is there no option to switch to a more natural color profile under the stock rom/kernel, but the panel also isn't the brightest and burn-in is a noticeable problem, especially thanks to Motorola's insistence on using software keys instead of hardware navigation buttons. Despite these flaws, it is functional and usable, but the cartoony/awful color calibration just looks goofy. Turning the brightness down low takes it from "kind-of silly" to laughably bad. As a short-term backup/tester, it is acceptable, but I wouldn't daily this thing long-term without installing a customer kernel and applying some corrections.

Quirks: Like the Moto X Pure Edition, the Nexus 6's screen is set very low on the face of the device (although it is less noticeable on the former). I'd imagine that this serves to make the machine slightly more manageable duing single-handed operation (like a hardware implementation of Apple's "reachability" :D) and also to improve visual symmetry with those software navigation keys (while the screen is on).

Also, the MicroUSB port is strangely upside-down on this phone.

Camera, Speakers: Seems comparable to the Pure Edition. Optical stabilization makes getting a steady shot in low light (or any lighting, for that matter) much easier and negates the need for digital stabilization in video recording mode, which improves field-of-view. Speakers sound about the same, although the hardware/software that drive them is noticeably "crustier" sounding. Still, it's very much usable.

Wireless Radio performance and compatibility: Didn't test side-by-side, but anecdotally seems identical to the Pure Edition. The massive number of GSM, CDMA, and LTE bands supported by this device is highly impressive, just like the Pure.

Vibration motor: Still noisier than it should be, but not quite as terrible as the Pure Edition. Also feels a bit stronger.

Software: Bland and boring, but gets the job done. I miss the Motorola camera and flashlight gestures (although the power key double-tap eliminates the need for the former) as well as the IR-assisted active display feature. Also, the "attentive display" (which keeps the screen awake as long as the camera can see the user) was very much missed. Also also, I was disappointed to see that there is no way to enable any kind of "night mode," even on the latest-and-greatest Android 7.1.

Conclusion: Nexus 6 is a good phone for the price these days. The camera is better than I originally gave it credit for, but don't buy this phone for its screen. If you want a cheap (but modern) Android phone that works on Verizon Wireless and can have its bootloader unlocked easily, (but don't want to pony up the additional $35-60 that the Moto X Pure Edition sells for) it's hard to go wrong with the 6. The battery is not user-replaceable, but holds up well. And, unlike the Nexus 6p, it won't fold in half!

Bottom line: Budget-minded Verizon customers might be better off with the Pure Edition, but if even that phone costs too much, the Nexus 6 is not a bad consolation prize. I couldn't ask for a better secondary/tester device.
