Note 7 may be first with two ambient lights sensors for precise autobrightness settings

Note 7 may be first with two ambient lights sensors for precise autobrightness settings
Samsung's Galaxy Note 7 is no doubt stuffed to the gills with sensors, perhaps more than on any other phone, as it now includes an iris scanner and a sensor that lights up the display when you tilt the phone toward your eyes. It turns out that there might be even more than we thought, though, namely a second RGB sensor on the rear for ambient light measurement that returns faster and more precise auto brightness adjustments for the display.

The tip about that second ambient light sensor (ALS) is included in the Note 7 writeup by the screen calibration specialists from DisplayMate. The folks over there explained that using just a front-facing ALS, as on most phones, might be deceiving in certain situations, as your body may cast a shadow on it, while your eyes have adjusted to the general ambient light around the phone, hence the extra sensor on the rear. 

Where exactly is that sensor located is not very clear, though - looking at the Note 7's back, one sees only the camera, flash, and heart rate sensor contraption. The pulse scanner does emit light, and has another component at the top, so it might be combined with ALS, but we'll have to probe Samsung for more details. On another note, the Note 7 is listed as able to reach 1000+ nits of peak brightness in auto mode when there is high ambient light around it, so that second sensor might be coming in handy to gauge the precise situation you are in. 

Moreover, Note 7 is the first phone whose display is certified to display HDR video, and one of the requirements for the standard is that peak brightness is no less than 1000 nits, though it seems made for LCD displays. In any case, it's another interesting tidbit added to an already monster device.

Um... Actually I don't think Note 7 is a big upgrade and despite all these nice features, I waited so long to see things like 6gb ram and SD821... I'm disappointed. Anyone has any ideas why we shouldn't wait for SD830 and 6gb ram and those nice upcoming cameras?

Man...just buy a phone, and use it. What will you do with 6 gig of RAM, that you can't do with 4? And just how much faster in day to day usage is the 821? Are you gonna use your phone practically, or seek out people with an 820 chipset to do speed tests against all day?

I mean c'mon man lol. It's not that serious, The 7 is a nice upgrade in almost every area.

Actually my other side says that too... but uh I did that once and I regret it. Numbers don't lie. It's like the difference between iPhone 5 and 5s... just a year and so much change. And now people even remember iPhone 4s but not 5. And exactly like Note 7, all iPhone 5 brought was design change

Note 5 was the one with "only design changes", and also downgraded battery, lack of memory options and not a lot of reasons to upgrade, this time they are packing a lot of nice improvements and features in there, some of them borrowed from the S7 but they're still top n toch. We don't even know if the SD821 is ready and free of issues since not a single phone has used it yet, even the rumored specs from V20 points SD820 SoC, the same can be said about the exynos 8893 or whatever is called. At this point is unsure those updated SoCs will ever see the light since 2nd half 2016 phones are using SD820 and next year will welcome SD830 and new Exynos. So the only "non- top tier" feature is the 4gb Ram that doesn't make any big difference (if any) on a current phone.

They dont pursue S821 because simply the SoC hasn't ready yet. Nobody has ever touched the S821 Asus Zenfone 3. "S821" is simply the marketing from Asus. And remember Samsung has to prepare millions of components before the release of a S or Note phone, so for S821 it should be November. Similar thing for 6GB of RAM. The global supply of RAM is deficit now, so maybe not enough supply for Note 7.

Uhm, you consider iPhone 5 to 5s a "big" change yet you consider the Note 5 to 7 a minor change? What exactly made that a "big" change yet makes all of the following additions over the Note 5 a "small" change: Dual Edge symetrical design + Refined Grace UI + 500 mAh added battery capacity + LTE Cat.9 brings faster data + Better Screen to Body Ratio + 64 GB Base model + MicroSD Card Expansion + Waterproof + More precise Active digitizer pen + IRIS Scanner + Gorilla Glass 5 + Better Camera + Faster Processor + USB 3.1 Type C Port + Higher Display Birghtness for better outdoor visibility + This minor Dual Ambient Light sensor setup

Also aluminum 7000 frame, HDR display, and touch sensor printed to the gorilla glass 5 for fast touch response.

Maybe you're comparing it to the S7 and S7E too much, compare it with the Note 5 and you'll appreciate the changes.

LOL.."seek out people with an 820 chipset to do speed test against all day"..interestingly enough there are a couple of people on here who I'd imagine doing that

6GB of RAM will be a breeze to play with tweaks, mods, custom ROMs, etc. i'd take OP3 anyday.

All I heard was Wahhhhhhhh. Here have a bottle! You're disappointed over a RUMOR that was never confirmed. Yea that is really smart. Did Samsung tell you the phone would have a SD821? Did Samsung tell you it was going to have 6GB of RAM? Because if they didn't tell you and they are the source, than anyone telling you otherwise is no more than hearsay. If you "chose" to base your purchase solely on hearsay, that its your fault. Buy the phone or not, I personally could care less. But to cry about the fact you did no fact checking on your own is stupid. Stop crying like a lil "baby".

That screen is probably better than the one on iphone 10s!

The second ambient light sensor is at the bottom right corner of the camera lense..I know cause I had an in-depth hands on with the device before pre-ordering. I didnt know what it was at the time though and it only shows when light reflcts of the back at a certain angle. Also this article kind of glosses over a lot of the results from Displaymates test namely the lowest ever screen reflectivity, improved brightness to contrast ratio among others..

Actually if you look at the Note7 images on GSMarena you can kind of see ithttp://www.gsmarena.com/samsung_galaxy_note7-pictures-8082.php

So iphonearena instead of mentioning the title as note 7 display can reach brightness above 1000 nits, they are telling about 2 ambient sensors......as expected.....

12. sarcastic_nerd unregistered

That kind of brightness is only reached in 1% APL in high ambient light solution for a limited period of time. Also, 1000 nits is minimum for HDR display qualificaton. So I think it was quite obvious. Phones from years past like the Xperia P have reached 1200 nits on 100% APL. So not a big deal. This is way more important compared to 1000 nits because I have never found a single phone with decent auto brightness.
