+Vincent Sergère review of the Nexus 5X for +FrAndroid

Even in case you can't rely on translation from French, take a look at the +GameBench stuff!

He also sent me the measurements, made with my software #SensorMaster of two units, one of which have a lot more yellow white point than the other so that was interesting to have the full data on that.

First unit (more blue): 432 cd/m² maximum white point, 1326:1 contrast ratio
Second unit (more yellow): 495 cd/m² maximum white point, 1527:1 contrast ratio

Interesting discrepancy, because it also means that the yellow one could absolutely be re-calibrated to match the more blue one both in white point, contrast ratio and maximum brightness!

Google Nexus 5X
Le Nexus 5X, issu de la collaboration entre Google et LG, est un terminal qui plaira forcément aux amateurs d’expérience Android pure et notamment aux possesseurs d’un Nexus 5 qui ne veulent pas d’une diagonale d’écran trop élevée. Face à son prédécesseur, le Nexus 5X a beaucoup évolué, notamment sur sa partie photo qui devient enfin utilisable avec des clichés de qualité mais aussi avec son autonomie, même si cette dernière reste encore un peu e…

Interesting video by +Russell Holly​​​​​​ for +Android Central​​​​​​

His initial approach in the video is to comfort people wondering if the +Nexus​​​​​ 5X, they might have just ordered is actually slow.
What I got from the video however is that a difference in performance between the 5X and the 6P is much larger than I expected.
Like 1-generation gap difference of real-world performance.

In the attached article's comments, there's a link to this other video made by +Android Headlines​​​​​​ which doesn't show as much gap apparently.
It's interesting as second take.

Watching this new type of videos becoming popular, evaluating the amount of time you wait when using your phone and multitasking capabilities makes me wonder about the possibility to replicate those in an automated way.
It might be possible to script all that, and get some quite valuable metrics allowing to compare phones quickly.

Maybe a few Android publications could team up and fund the development of such evaluation tool.

Both +Nexus​ 5X and 6P have interesting slow motion capabilities!

With sound, not suffering from obvious aliasing artifacts, offering good detail instead.
While I'm looking forward to direct comparisons with iPhones 6 and 6s, they appear to be by far the best Android phones in this department to date.

Thanks +High Speed Cams​ for the early samples round-up.

Nexus 6P Slow Motion Quality is Great! – Hi Speed Cameras
Now that the Nexus 6P has been getting into the hands of reviewers you can clearly see that the slow motion mode has great quality. It has audio same as the iPhone and the resolution in 240fps mode is on Par or might be better than the iPhone 6s.

The early #Nexus 5X and 6P camera samples popping up are really not that good

Most of them are overexposed with large parts of the photo burned out, automatic white balance doesn't seem too consistent with some pics too blue and others too yellow.
At least they're in focus.
Low-light seem to be a winner however.

Most reviewers don't say if the pics were taking with or without HDR+. Maybe only HDR+ is alright and standard mode just poor.

Google has a lot of work to fix this camera.
I mean, getting the exposure right is the very first thing. You'll see this illustrated in comparison with Galaxy S6 or iPhone.

(early opinion based on the very first samples published)

+Android #Marshmallow #Doze experience:

On my #Nexus5 , it does the job just as promised and since I flashed Android 6.0 the battery life has been predictable again.

All that despite the unit is paired via Bluetooth LE with an Android Wear Smartwatch, and tracks my exercise with Google Fit with activity detection enabled.
The later relies on and activates location history.

On #Lollipop , unexpected and hard to trace battery drain were happening often; most of the time I was unable to identify their sources.
Even complete airplane mode was not sufficient to prevent battery drain during the night so yeah, the Nexus 5 was not behaving correctly under 5.x.
Many other non- #Nexus devices were just fine in the same configuration however.

So far I've noticed only one drawback of #Doze with my current usage pattern:

If the phone stays on the desk for a while and I go out of Bluetooth reach shortly – like a few minutes ago while taking out the trash: the Android Wear watch can't reconnect to the smartphone for a few minutes once I come back.
But it connects again as soon as I pick-up and turn on the phone.

I'll try to reproduce that once more and disable power optimizations for Android Wear app after that to see if it solves this particular issue.

Currently there's no notification that I have to receive urgently so I'm not worrying about the rest like +Andrew Martonik mentioned.

Inside Marshmallow: What is Doze, how do I use it and what does it do?
Android Marshmallow has changes deep in the operating system that can allow your phone (or tablet) to get better battery life. We see this mentioned with every operating system update from every company that makes smart devices, but this time they mean it. Enter Doze. If the name reminds you of a pleasant nap while nothing pressing is going on, you’ve figured out what it is. It’s a set…

New Nexus camera sensors

+Nexus​​​​ 5X and 6P cameras are indeed based on a large sensor, and choosing this characteristic appear to be indeed legitimately at the expense of OIS.
The IMX377 is a 1/2.3 type: 7.81mm diagonal

In comparison, the Galaxy S6/Edge/Edge+/Note 5, LG G4, is 1/2.6: 6.828 mm (in 16:9)

It's the same sensor diagonal size albeit in 4:3 than the 16:9 1/2.3 type in the Z1 to Z5, which don't have OIS either.

More sensor sizes in phones: https://en.m.wikipedia.org/wiki/Exmor

Note: 1/2.3 for 4:3 format is more surface area than 1/2.3 for 16:9 as this metric characterize the diagonal and not the surface area that captures light which evolves at the height x width (aka square)

Nexus 6P AMOLED panel info

"SW: It has a Samsung WQHD AMOLED panel. We have spent a lot of time tuning the white-point and color gamut for these panels – hope you will enjoy the accuracy of the display."

"Yep, confirmed: Nexus 6P has the latest generation panels from Samsung. One of things we deeply care for is the quality and accuracy of the display through which all of us connect with the stuff we care about. We created a very tight spec (white-point temperature, delta-E variance, color-space accuracy, etc) for the 6P WQHD AMOLED panel, so it was important that we use the most cutting edge panel technology available."

That sounds good, and especially after +Dave Burke​​​​​​​​​​ claimed on stage that the display was "very vibrant", this promise of color accuracy will need independent verification 😉

Note that this answer doesn't specify to which color space or white point they decided to conform.
This display will show near exclusively content encoded to sRGB standard (which specifies the white point and RGB primaries, gamut and electronic-optical transfer function – aka EOTF aka gamma curves).
In case the display colorspace they chose is wide gamut, any color accuracy claim is automatically moot given the fact Android doesn't support color any management at the moment.

There are various ways to calibrate a wide gamut AMOLED to conform to sRGB specifications tho: using the panel's factory calibration in conjunction with either:
– the panel's color tuning
– Qualcomm Mobile Display Controller image processing, with basic colorspace conversion or 3D LUT
– the GPU (which taxes some GPU power however)

The +Nexus​​ 6P slow motion video shared by +Dave Burke​ is well chosen and a delight to watch

Properly exposed, satisfying colors, no visible noise, and busy background in an out of focus bokeh blur.

We can observe some aliasing artifacts however, likely due to line-skipping high speed readout from the sensor.
It might be more aliasing artifacts than the iPhone slow-motion, and comparable to other Android phones on the market.

Later samples and comparisons will tell!

DXOMark evaluates new Nexus cameras

The numeric score is high.
But I guess you already know my opinion on averages of averages of numerical scores to evaluate image quality 😉

– it's always the same thing: each score is valid only if considered alone, and all that only in case the evaluation metric is indeed perceptual and not just arbitrary.

Pro / Cons comments are interesting tho.

Google Nexus 6P review: Serious contender for mobile photography | DxOMark
Today Google unveiled the Nexus 6P. Having partnered with manufacturer Huawei to build this latest device, the Nexus 6P is the first to run Google’s most up-to-date version of its Android operating system — Android OS 6.0 Marshmallow (or “Android M”).Tech specs for the Nexus 6P include a large 5.7-inch (1440 x 2560-pixel) AMOLED screen with Corning Gorilla Glass 4 and 16 million colors. The rear camera offers a 13Mp resolution on a 1/2.3”-type se…

Nexus 6P and 5X USB Type-C Charging

According to the product pages for the +Nexus 6P: https://store.google.com/product/nexus_6p and 5X: https://store.google.com/product/nexus_5x, both device conform to the USB-C standard instead of +Qualcomm QuickCharge 2.0.

On one side, it's great because it's a future-proof standard instead of a proprietary technology.
On the other side, +LG Electronics and +Huawei only ship a 5V charger.
Because the connector is of USB Type-C instead of Micro-USB, they pump up to 3A instead of 2A (QuickCharge 1.0 / Samsung) or 2.4A (Apple)
But 15W is less than to 9V / 2A (18W) or 12V / 1.8A (21.6W) from current QuickCharge 2.0 devices specs.

3A on 5V also means any long cable will waste energy, substantially less than 5V making it to the device depending on the cable quality and length.

Maybe these two phones will also accept 12V input as well (unlikely 20V) as it's part of the USB power spec.
That'll be up to the reviewers to determine and measure that.

Meanwhile, don't expect these phones to charge as fast as the current Motorola or Samsung generation.
As mentioned in the presentation today, they'll still charge a lot faster than the iPhones.
