The Samsung Galaxy Note7 (S820) Review
by Joshua Ho on August 16, 2016 9:00 AM ESTIC Design Wins
While we normally allude to the various things that we find in a phone in the interest of providing some extra depth for posterity I went ahead and dug through the software to find all the various peripherals that are present in the Galaxy Note7. For example, the Wacom digitizer identifies itself as the W9010 over i2c, which is interesting considering that this digitizer is the same one found in the Galaxy Note 3. In various briefings it was explicitly said that the digitizer supports double the number of pressure levels, so I’m not sure how this is achieved or if it really has any changes at all besides the smaller tip.
Moving past the Wacom digitizer we can see that there are a number of supporting ICs for power management and things like the battery charger. I’m not going to spend a ton of time talking about this but a huge number of these are Maxim Integrated ICs such as the MAX77838 switching regulator/PMIC, although I’m not clear on exactly what this PMIC supplies. There’s also the MAX77854 which functions as a PMIC, as well as a MAX98506 class D audio amplifier for the codec, which is likely used to drive things like the earpiece, speaker, and 3.5mm jack. This is shared with the Galaxy S7 and S7 edge and it looks like it uses the same WCD9335 audio codec so I wouldn’t get my hopes up about improved audio quality for the Snapdragon variants. If you want better audio you’re going to have to look towards the Exynos variant or the HTC 10.
Moving to slightly more boring but critical parts of the Note7 there are ICs like Cypress CapSense PSoC which enables the capacitive buttons and a TI BQ25898S battery charger IC which supports 9V and 12V charging voltages for adaptive fast charge. There’s also an NXP PN547 NFC controller and an NXP P61 secure microcontroller that seems to be for payments and similar applications. It should also probably surprise no one that there’s a Validity/Synaptics VFS7xxx fingerprint scanner here, although I found some mention of an Egis Technologies ET320 fingerprint scanner which makes me wonder whether Samsung is dual sourcing here.
The more esoteric ICs here include a Richwave RTC6213N FM radio tuner and a CEVA DBMD4 DSP which seems to be for always-on voice commands which are visible on i2c and SPI respectively. The only IC that I can’t identify at all is something called the SX9320 over i2c, which officially has zero mentions on the internet unless you count a Shacman trailer that is manufactured by Shaanxi Automobile Group in China or NGK spark plugs. At any rate, looking at these kinds of details it’s much more apparent just how critical economies of scale are as these are parts that seem to be shared across the Galaxy S7 and S7 edge, which surely helps to drive down cost due to the sheer volume of these devices. There are also things like FM tuners which aren’t necessarily going to be a point of advertising for a phone but are neat to have anyways.

The typical half glass full, negative approach when reviewing Samsung devices at Anandtech... I guess more of you guys wants a job at Apple like the one Anand managed to get?theduckofdeath - Tuesday, August 16, 2016 - link
Half glass empty, that is...See, I'm simply not capable of being as negative as an Anandtech writer. :)

I hate to hear the "Anandtech is posting biased reviews" argument because they do such a good job of being in-depth, and I appreciate their reviews tremendously. However, I agree that there is a bias in the wording, intentional or not, against Samsung's recent Galaxy phones, which have been spectacular options in the Galaxy S6/S7 era, even in spite of Touchwiz's shittiness.Is Samsung's aluminum and glass industrial design and unique bezel-free design really so bad? Anandtech thinks it's tired and needs a refresh. In The Verge's review, they come up with a completely different conclusion - they say the Note 7 the best big phone ever, and praise how Samsung has out-designed the competition. Such a huge discrepancy down to essentially a matter of taste. Can we not reach a middle ground - every review of a Galaxy review on AT needs to mention how they need to spice up the "rectangle with rounded corners". It's fine for what it is!
----
To take just one example to hone my point, The iPhone 6S's camera in the AT review was rightly praised for its improved video - 4K recording and 1080p 120 fps. However very little was made of how it was essentially the same damn sensor as the last gen with shrunken pixels giving it a nominal bump from 8MP to 12MP, with basically zero quality difference in stills.
In the Samsung Galaxy S7 review, the super fast laser Autofocus was mentioned, but the overall image quality was described thusly "However, with that said the output of the Galaxy S7 and S7 edge’s camera is not that impressive. I would argue that while it’s not worse than the iPhone 6s Plus, it is basically comparable."
It's not that impressive, yet equal to the iPhone 6S Plus. There was nothing in the iPhone 6S review or conclusion that described its camera as mediocre, yet that's how it comes off in the S7 review - Samsung has to be better, or it's unimpressive.

Samsung has to be a lot, LOT, better, or it's unimpressive. FTFY.It's a mentality that really kills me.

Exactly.Just because a person writes a ten page biased review it really doesn't make it less biased. This place just can't learn from old mistakes. Anandtech used to be a place you could go to to read reliable in-depth reviews about technology and gadgets. I don't know exactly when that changed, but I guess it was a long time ago when Anand had received enough gifts and perks from Apple to sway the whole writing culture on Anandtech.

Here in the UK, though, they're charging £700 for it. You could buy two OnePlus 3's (£329 each) and still have change. Don't get me wrong, this is surely the better phone. But is it really worth twice the price?lilmoe - Saturday, August 20, 2016 - link
Then why isn't the same being said about every other expensive phone???Meteor2 - Saturday, August 20, 2016 - link
It is.theduckofdeath - Saturday, August 20, 2016 - link
Read the first page of the iPhone 5 SE review and you'll get some perspective. An over-priced cynical release that Apple released thinking consumers were all stupid. Not a single complaint about Apple reusing the exact same hardware of a phone they had released several years earlier, and still asking for a stupid high price.This Galaxy Note 7 is still using a really unique design language that no other brand has managed to copy. Read the first page of this review again.
This site has gone down the drain as an Apple marketing portal. Which I guess is why the comment sections are really starting to die. Because you know, people are not as stupid as Apple and Anand and his minions seem to think.

How can you say that when they do absolutely the best reviews, which are based on actual and realistic measurements. If you prefer superfluous reviews go to The Verge.
