Hands On With the LG V20

The LG V20 at this point has been leaked to death, but it’s finally here. LG has been pushing through a fairly tough year, so this phone really could not have arrived at a better time with the Note7’s battery fires and recalls as the obvious alternative to the Note7. To try and start our discussion of the LG V20 we can first take a look at the specs before we jump into the other major areas of note.

At a high level, the LG V20 honestly doesn’t look all that different from the LG G5 in a lot of ways. It shares the same SoC, the same rear camera, and retains the rear-mounted fingerprint scanner that also doubles as a power button. However, there is a bump in battery size and display size, and things like the new front-facing camera and secondary display help to differentiate it from the LG G5.

However, the single biggest change here is design. While the LG V10 had a plastic back cover and a glossy stainless steel frame, the LG V20 adopts a fairly elegant aluminum design. The phone has a metal frame to give it strength, which holds the major components and provides the screw holes for the plastic cover that helps to protect the internal components. Over this plastic cover, LG adds the aluminum back cover. This aluminum back cover appears to house the NFC antenna but not much else other than a whole host of grounding points. All other antennas are probably in the top and bottom RF windows for this device. Judging by the writing that says BYD on this back cover, it wouldn’t be a surprise to know that BYD Electronic is making these back covers for LG.

Overall, I think this phone feels like a massive step ahead the G5 when it comes to in-hand feel and overall design. LG is quite possibly the only OEM that has ever properly integrated a removable battery and an aluminum back cover at this point, and while this is a pre-production unit my subjective opinion here is that this is actually a fairly handsome design. The earpiece has this fine detail to it and it’s pushed up right along the edge of the glass. Even the LG logo is subdued, and is color matched fairly well to the plastic that flanks the display. On the back of the phone, everything is aligned fairly well. This isn’t a huge deal as far as actual purchase recommendations go, but it’s worth mentioning because it looks like LG cares about ID even if they don’t market it aggressively.

 Moving past design, things like the combined power and fingerprint scanner have gotten noticeably better moving from the G5 to the V20. The button no longer has a significant amount of slack or play that I saw in many G5s, and the button clicks much more solidly now. The volume buttons also feel great, but they appear to be placed only to work well if you hold the phone in your left hand as holding the phone in your right hand doesn’t really leave any viable method of comfortably and safely manipulating the buttons. This isn’t a huge issue if you mostly set and forget volume settings though.

Booting up the display of the LG V20 reveals no significant issues with backlight bleed, but right off the bat it’s obvious that the display is on the cold side. It’s hard to say whether this display is still making the mistake of a gamut wider than sRGB when Android doesn’t support color management, but for now I’m not going to make any snap judgments even though LG is a bit notorious for not getting color calibration right.

Playing with the camera right away it’s obvious that LG has dramatically improved their camera UI for the V series relative to the G series, which makes me wonder why the G5 shipped with such a seemingly gimped camera application. The manual camera is not necessarily anything special, but manual video settings for bitrate, audio recording, and a number of image controls is really great to see and something that I haven’t seen on any other devices out there. Audio even has low cut filters for things like concerts where bass is often overwhelming for reasons beyond me. There’s extra video stabilization, but in a hands-on context it’s difficult to test these things properly.

LG is also emphasizing audio quality, with the ESS quad DAC that has a 132 dB SNR and 124 dB of dynamic range that should make it extremely difficult to notice things like hiss when the DAC is on. Voltage output is said to be double that of anything else out on the market at time of release as well which is nice to see. This is contrasted with the LG G5, which shipped with a somewhat disappointing DAC out of the box and needed the B&O module to really get good audio quality. Seeing as how a major device launch meant the loss of the 3.5mm jack altogether it’s worth mentioning that this device does have a 3.5mm jack on the bottom right of the phone.

The final thing worth mentioning given that I’ve had some time with the preproduction unit at home is that LG is now using SK Hynix’s UFS 2.1 solution, which is supposed to allow for better security between SoC and UFS device. This is also using 3D-V2 NAND which might be the first shipping implementation of 3D NAND I’ve ever seen in a smartphone. This actually leapfrogs Samsung which is impressive to say the least.

Overall, the LG V20 is a fairly interesting phone but I get the sense that it might be overlooked in the sea of other launches to come. LG UX 5.0+ is a decent redesign at first glance but may need some extra work, but the phone itself is actually fairly good at first glance. The LG V20 will be available through Verizon, Sprint, AT&T, and T-Mobile US in Titan and Silver.

Hands On with the iPhone 7 and 7 Plus

As the iPhone 6’s design turned 2 years old the iPhone 7 was launched to continue the two year cadence for their smartphone designs. As you might expect from a phone like this, rather than maintaining the same industrial design that we saw with the iPhone 6s instead we’re looking at a new, more refined design.

To get what I’m talking about, we can start with the iPhone 7 proper, which is the 4.7 inch variant. Broadly speaking if you were to only look at the shape of the phone there isn’t a ton that has changed, but if you look at all of the design elements together it’s clear that the design has changed in a fairly meaningful way. From the front, looking at the display you still get a familiar design as far as the earpiece, front-facing camera, and other sensors on the top, with a single home button on the bottom. However, unlike previous iPhones the button is solid state. I’ll have some more thoughts on this soon, but the home button still looks like previous iPhones because the fingerprint scanner isn’t placed underneath the cover glass. It also looks like the fingerprint scanner still uses different materials as the reflectance is clearly different, so this should still be a sapphire crystal.

Moving on to the back cover of the phone the Jet Black version of the phone is clearly finished to a high gloss, despite using an aluminum back cover which usually have a sandblasted finish. This finish looks pretty nice for about the 3-4 seconds that it remains glossy, as unless you subject your hands to a bath of isopropyl alcohol I find it unlikely that you won’t immediately cover the phone in fingerprints. The high gloss finish honestly wouldn’t feel that different in the hand from hyperglaze in the Galaxy S3 other than the noticeably different heat conductivity of aluminum. Interestingly enough the new antenna demarcation lines are now running along the edges if you look at the phone from the back. When it comes to the jet black version, it’s much harder to notice the antenna lines because the color matching is fairly close and the plastic feels hard and glossy to the touch much like the aluminum itself. Of course, any other color is going to be more obvious in this regard but this phone is probably the closest Apple has gotten to replicating the monolith from 2001: A Space Odyssey.

As far as design goes, it feels like Apple’s ID team has collectively gotten over the whole idea of trying to hide the camera hump. Rather than an extremely thin aluminum surround to hold the small cover glass of the camera, the lens has become larger and the hump itself is now integrated into the chassis itself. It’s much more obvious than the iPhone 6s, but I personally think this makes a lot more sense than continuing to pretend that phones don’t have camera humps, as this kind of design makes it less likely that the phone will rock around when it’s placed on a flat table.

Along the left and right sides of the iPhone 7 we continue to have the same button layout, with power on the right and volume buttons on the left. The silent toggle switch remains identical to the one seen in previous iPhones. The main point of interest, and I suspect controversy is going to be along the bottom of the phone.

Along the bottom edge, there’s a set of speaker holes, a Lightning port, and another speaker port. I suspect at least some of these holes house a microphone rather than just being two speakers, but I guess this makes more sense as far as visual balance goes and helps distract from the space left by the missing 3.5mm headphone jack. There’s too much to be said here to just have a single sentence, so we’ll cover this later. As far as the design of the iPhone 7 Plus goes, it’s really just more of the same. However, the iPhone 7 Plus has a significantly changed camera housing to allow for dual cameras. I got to spend some time with the matte black version for the iPhone 7 Plus though, and I think this traditional sand-blasted finish is just clearly superior. The antenna lines are more obvious but the finish is less susceptible to scratches and doesn’t show fingerprints nearly as much.

As far as usability goes, it’s hard to make any snap judgments of performance, so I’m going to restrain from any commentary here until I actually get some time to sit and stare at two different phones side by side to give any thoughts here. I didn’t see any noticeable frame drops, but when you’re mostly using system applications it’s usually almost impossible to notice these things unless something is seriously wrong.

Things like the new solid-state home button are a huge step forward as far as feel and reliability goes, but in some sense knowing that this is ultimately a capacitive touch sensor with some force sensing was somewhat confusing at first because I touched the home button the way I would an HTC 10 and expected it to work off of almost no actuation pressure. If you treat this home button like a physical home button though it works just as expected, and feels just like a real button. Unlike a real button it’s unlikely that you’ll ever break this home button though, so with time I’ll probably see less people using on-screen buttons to compensate for broken home buttons.

In the case of the iPhone 7 Plus, the dual camera works well within the functionality implemented. At this time it looks like the only feature available is zooming, and it’s definitely possible to see much more detail from the zoom lens than with the wide angle lens, but I’m not really able to say much else at the time because without the ability to test the camera in a room with dim lighting or the ability to walk around with the phone at night with a tripod means that I can’t provide any meaningful commentary on the performance of the camera at this time. Similarly, things like the front-facing camera and IP67 resistance cannot be tested reasonably in the context of a hands-on lasting less than 20 minutes.

What is worth mentioning here is that the stereo speakers work quite well. Although the demo room was loud with the sound of multiple journalists trying to film and talk into a camera, it was actually possible to hear something from the speakers which is honestly quite impressive. I can’t tell whether the top speaker has a different frequency response than the bottom speaker, but I wouldn’t be surprised to know that the setup here is similar to the HTC 10’s design in that regard. The final point of interest here is going to be the 3.5mm jack, and for better or worse it’s been removed. I’m still trying to get details on the specifics of this implementation, but if you have earbuds that use the 3.5mm jack you’ll have to use an adapter that comes with the phone that plugs into the Lightning port.

Really though, it’s obvious that Apple is trying to push people towards using wireless headphones of some shape or form, as there were quite a few AirPods available for demonstration.

Pairing of the AirPods was shown to just be done by holding them near the device and pressing the connect button whenever it popped up. Once paired the earbuds go into the ear, with automatic playback through the earbuds if the proximity sensor is tripped and pausing if it detects removal once playback starts. Double tapping the earbuds will cause it to activate Siri, and it looks like the microphones do some noise cancellation in order to enable better calls and voice commands. However I didn’t really see any evidence that active noise isolation is active in these earbuds so they won’t really isolate you from the environment.

Overall, the iPhone 7 and 7 Plus look to be interesting to say the least. There are a lot of things that a hands-on can’t cover like the new SoC, whether the loss of a 3.5mm jack really matters, and whether the phone represents a major upgrade overall. Regardless, the iPhone 7 and 7 Plus go on pre-order on September 9th, and will be available for sale on the 16th and will be available in Jet Black, Black, Silver, Gold, and Rose Gold.

Apple Announces iPhone 7 & iPhone 7 Plus: A10 Fusion SoC, New Camera, Wide Color Gamut, Preorders Start Sept. 9th

Today at Apple’s annual iPhone event held in San Francisco’s Bill Graham Civic Auditorium, the company announced their next generation of iPhones: the iPhone 7 and the iPhone 7 Plus. As you might expect from Apple’s history, the two phones incorporate a number of new features and feature upgrades compared to their immediate predecessors. This includes a new SoC – the A10 Fusion – new camera options, IP67 water resistance, and top-to-bottom support for both wide color gamut (DCI-P3) displays and photography.

Jumping right into the heart of matters, in previous years Apple has alternated their upgrades between the overall design of the phone and focusing on the internal processors, resulting in the usual iPhone (X) and iPhone (X)s cadence we’ve seen over the past several years. For the iPhone 7, Apple has kept with this general development process, however relative to the iPhone 6 and 6s generations, the iPhone 7 isn’t quite as significantly a departure as past designs.

Design & Features

The overall body of the iPhone 7 series is rather similar to the iPhone 6 series.  Both the regular and the Plus phones have virtually the same dimensions as their 6s predecessors, so the size of the phones is unchanged. Button placement also hasn’t changed, with volume and power buttons on the left and right sides of the phones respectively. The curved design of the iPhone series has also been retained.

So what is new for the iPhone design? In short, water resistance and a lot of polish. Apple has finally added more complete water resistance into the iPhone design for the iPhone 7 series, and the latest phones are IP67 rated for water resistance. Like we’ve seen with other IP67 phones, it should be noted that water “resistance” is the key word there; this level of protection is designed to resist water damage to the phone in the case of accidents, and it’s not meant for long-term submersion (swimming and the like).

Meanwhile on the polish side, for this generation Apple has further refined the overall design of the iPhone. Apple has taken a particular interest in going “seamless” this generation, further reducing the presence of seems in the phone where the glass meets the case and along the antenna bands. Apple has also introduced some new color options here: a matte black finish (seemingly replacing Space Grey), and a glossy “jet black” finish, the latter of which literally involves a polishing process. Apple is treating the jet black finish is this generation’s premium finish option, and as a result it is only available on the more expensive 128GB and 256GB phone models.

However the biggest change here is probably the home button, which is now entirely solid state. Apple has integrated their force touch technology previously used for the iPhone 6s screen and the MacBook trackpads into the home button, removing the mechanical aspects of it. Instead, like the aforementioned devices, what you’re looking at is a pressure-sensitive surface with the taptic engine being used to simulate the necessary feedback. The home button was one of the last few mechanical parts in the iPhone, and Apple is touting this as improving the reliability of the button. At the same time I wouldn’t be surprised if it was also part of the work that went into making the phone water resistant. It will also be interesting to see what Apple eventually does with the pressure sensitivity, given that they’ve tried to make it an important part of the user experience with the iPhone 6s and its force touch screen.

On the display side of matters, Apple has taken a page from this year’s 9.7” iPad Pro launch and upgraded the iPhone for DCI-P3 wide color gamut support. Apple has increasingly been going DCI-P3 capable throughout its entire product lineup, and P3 is quickly becoming by far the most commonly supported of the wide gamut standards across the industry. In the case of the iPhone 7, this is part of a larger upgrade to implement top-to-bottom wide color gamut support, with the phone’s cameras also getting a similar upgrade. The advantage of the larger color gamut, as we’ve seen with the iPad, is that it allows for representation of “deeper” colors that can’t be covered by the traditional sRGB color space, ultimately getting closer to reproducing the full spectrum of what humans can see. As pointed out by our own Brandon Chester however, these new phones don’t include the iPad’s True Tone capability, which allows the display’s white point to be changed with the color temperature of the surrounding lighting.

Along with the addition of wide color gamut support, the panels in the new iPhones are also 25% brighter according to Apple, with a typical max brightness of 625 nits (for reference, we measured the max brightness of the iPhone 6s at 567 nits, compared to an official spec of 500 nits). What hasn’t changed however is resolution; these are still Retina HD displays, meaning we’re looking at 1334×750 pixels for the 4.7” iPhone 7, and 1920×1080 pixels for the iPhone 7 Plus.

At the other end of the spectrum then are the iPhone 7 series’ new rear and front facing cameras. Starting with the iPhone 7, Apple has retained a 12MP sensor (sensor manufacturer unknown), however they have significantly improved the feature set available. The new camera module is capable of taking wide color gamut photos to go along with the WCG-capable display. Furthermore, in a rarity for a sub-5” phone, the iPhone 7 now includes optical image stabilization (OIS) for both photos and video recording, a feature that was previously only available on the larger Plus phones. The new camera is composed of a six element lens, and along with its other improvements, the sensor is said to be 60% faster and 30% more energy efficient than the previous-generation sensor in the iPhone 6s. Also augmenting the new camera is an updated true tone flash light; the new module is composed of 4 LEDs, allowing for what Apple says is 50% more illumination than the iPhone 6s.

Meanwhile for the iPhone 7 Plus, Apple has added a second 12MP camera. What sets this second camera apart from the first is the lens; complementing the normal wide-angle lens on the primary camera, the second camera uses a 56mm, f/2.8 telephoto lens, offering a tighter picture with an effective 2x optical zoom over the primary camera. Apple has been pushing the camera aspect of the iPhone for many years now, and with the latest iPhone they are branching out into one of the few things most smartphone cameras haven’t been able to address with optical zoom. Besides allowing for closer photos, the second camera will also be used to do depth measurements, allowing the iPhone 7 Plus to do depth of field effects.

Finally, both phones have also received a new front facing camera. This new camera is 7MP, and like its rear facing counterparts supports wide color gamut photos.

As for audio capabilities, Apple has taken both a step forward and a step back. Moving forward, the headset speaker towards the top of the phone has been upgraded to be a full-fledged, full volume speaker. As a result, the iPhone can now play back stereo sound when in landscape mode by combining this with existing speaker at the bottom of the phone. Apple says the new speaker system is 2x louder – though it’s not clear if this is just adding up the output of the two speakers – and we’re told that the iPhone 7’s speakers support a greater dynamic range.

However taking a step back, as rumors have previously indicated, Apple has removed the 3.5mm audio jack on the phone. For external audio, Apple is now telling users and accessory manufacturers alike to use the Lightning port. Of note, this necessitates putting a Digital to Analog Converter (DAC) in headphones and other devices that directly connect via Lightning, which is going to have interesting ramifications on audio quality differences between products and how they are priced. Otherwise for existing 3.5mm devices, Apple is also including a Lighting to 3.5mm audio adapter, which of course also integrates the necessary DAC.

Given that they’re removed the audio jack, Apple has upgraded their EarPod earbuds for the new iPhone. The new models are lightning based, though otherwise apparently unchanged from their predecessors. A bit farther down the line, Apple will be releasing a wireless earbud product, the AirPods, with which they intend to do away with concerns about wired connections entirely by going wireless.

A10 Fusion: The Next Apple SoC

Finally, last but certainly not least is the heart of the iPhone 7 and 7 Plus: the SoC. While Apple has traditionally focused on bigger improvements in the off-year s-generation updates, they have made something of an exception for the iPhone 7 with the A10 Fusion SoC.

The major change here is that with the A10, Apple has embraced the concept of multiple types of CPUs, each with different power/performance characteristics. This is something that has been prevalent in SoCs based around ARM Cortex-A CPU designs used in most Android phones, but Apple had (until now) opted to stay with a single cluster of two CPU cores.

There’s a lot of information to chew here, and a product announcement isn’t nearly enough to cover everything, but the basic theory behind a multi-type/multi-cluster design is to further min/max power efficiency by developing a set of high performance, high power cores for tasks that need maximum performance, and a second set of low performance, low power cores for simpler tasks that need only a small amount of computational time. By not sending the latter tasks to the high power cores, in theory you save on power consumption. This is the basis behind ARM’s big.LITTLE design philosophy.

The trade-off with this philosophy is that you now have to manage migrating tasks between the CPU clusters, which itself has a power cost. So while it’s a more efficient route in theory, in practice it can be difficult to implement, especially in a performant manner. Apple has previously stuck with their single cluster design, using the same CPU cores to run the gamut from low power to high performance, and while we may never get a full answer, I am very curious what happened behind the scenes at Apple and what they found to get to this point.

In any case, the A10 implements two types of cores; a pair of high performance cores, and a pair of low power cores. The slower cores are said to consume one-fifth the power of the high performance cores, though Apple has not indicated what performance is like. As is traditional for Apple, they haven’t said anything about the CPU cores themselves, but it’s a safe bet that the high performance cores are a direct descendant of the Twister cores used in the A9. More curious will be what the low-power cores are – given Apple’s fondness for developing their own ARM CPU cores and various technical considerations (such as the core interfaces), it may very well be that these are also Apple-designed cores, as opposed to an off-the-shelf solution like ARM’s Cortex-A53.

One thing Apple has emphasized in talking about the A10 is that their design uses a custom designed performance controller to manage the CPU cores and migrate tasks between them. This revelation of a hardware controller does imply that Apple is using some form of cluster or CPU migration – that is, only ever using 2 cores at once and not using all 4 cores at the same time in a heterogeneous manner – but all of this is speculation and subject to confirmation. Either way, this is the biggest change to the structure of Apple’s CPU subsystem since A7 and the Cyclone CPU core in 2013, and given Apple’s habit of throwing us curveballs on the SoC side, I suspect the answer is not as simple as what we currently believe.

Meanwhile on the GPU side, Apple has uncharacteristically confirmed that A10 implements a “6 cluster” GPU design. This removes a good bit of guessing work here, as the significant scalability of GPUs has always made it difficult to pin down the number of GPU clusters. A good bet here is that Apple is using another PowerVR design – either a higher clocked version of the PowerVR GT7600 used in the A9, or perhaps a six cluster design based on the more recent PowerVR Series7XT Plus architecture – but that’s something that remains to be seen.

From a performance standpoint Apple is once again touting significant performance gains versus the A9 and previous SoCs. CPU performance (of the high power cores) is said to be 40% better than the A9 and its dual 1.85GHz Twister CPU cores. Meanwhile GPU performance is said to be 50% higher than A9’s PowerVR GT7600 GPU. Obviously we’ll have to see how well performance holds up in our benchmarks, but if Apple can actually deliver on these claims then this would be a significant gain for a non-s generation product, and one made all the more impressive as Apple will not have received the advantages of a die shrink with this generation.

Finally, no information about the RAM paired with the A10 is available at this time. However we’re very happy to see that the traditionally conservative Apple has finally given the iPhone line a bump in NAND capacity. The entry-level model is now 32GB, and the higher capacity tiers have been bumped to 128GB and 256GB respectively.

Final Words

As for battery life, Apple has not released any hard details on the capacity of the batteries being used in the iPhone 7 and the 7 Plus. However they are claiming yet another increase in average battery life. Overall Apple says the average increase for the iPhone 7 over the 6s is 2 hours, and a smaller 1 hour increase for the iPhone 7 Plus over the iPhone 6s Plus. Curiously, Apple’s official 3G talk time numbers are the same (or have regressed) compared to the iPhone 6s, at 14 hours for both the iPhone 6s and iPhone 7. Instead Apple’s metric of choice is LTE internet use, which on the same phones has increased from 10 hours to 12 hours. So at first glance, assuming Apple hasn’t regressed on modem power usage, these power gains would seem to come from improvements to the A10 SoC and possibly the display.

Wrapping things up, Apple is going to be bringing the new iPhones to market rather quickly. Pre-orders for the phones open up on the 9^th, and they’ll begin shipping one week later on the 16^th. Phone pricing for the iPhone 7 is unchanged from the iPhone 6s, with the base 32GB model starting at $649 and each capacity bump going up $100 from there. Meanwhile the iPhone 7 Plus is just a bit more expensive, seeing a price bump at all capacities of $20, putting the starting price at $769.
