We’re a few days away from completing the 2020 calendar year, and it’s been a quite a hectic year for everybody. In times of troubles, the smartphone industry had been under a two-prong attack from both an economic stand-point as well as the from a product maturity standpoint – trying hard to innovate with new features to convince users to upgrade their previous generation devices. This year, we’ve seen several new industry trends make breakthrough advances in terms of technology in smartphones, beyond the obvious elephant in the room, by which 2020 will be remembered by: Big camera sensors, 120Hz displays, several large SoC moves, 5G, and several other vendor product choices.

Big Sensors go Mainstream

Although a subjective opinion, what I view as one of the most important developments in 2020 mobile devices has been the widespread adoption of larger camera sensors. While in years past, Huawei had been the notable exception to the rule in terms of adopting larger camera sensors in their smartphones, this year, we’ve seen almost everybody make the transition to larger formats – either 1/1.78” sensors or even the new humongous 1/1.33” beasts in some flagships.

Galaxy S20 Ultra & Galaxy S20+

Bigger sensors most of the time means that vendors are able to use bigger pixels – which in turn results in better dynamic range capability and better low light captures. This year we’ve seen many flagships at least adopt a 1/1.78” sensor which is notably larger than previous generation 1/2.3” or 1/2.5” units – resulting in 12MP 1.8µm pitch units like on the new S20 series and some other vendors such as Sony.

Other vendors have opted to go even bigger – ranging from 1/1.3” to 1/1.4” sensors. The most notable and talked about has been Samsung’s new 108MP units in the S20 Ultra and Note20 Ultra series. Although the high-pixel count sensors deployed on these devices have questionable benefits in their native resolution, the ability to bin 3x3 pixels down to an 12MP image means we’re looking at effective light gathering capabilities similar to that of a 2.4µm pixel pitch sensor, something well beyond other current sensors on the mobile market.

We’ve seen variations of these huge sensors – Xiaomi also uses a 108MP native unit but bins down by 2x2 to a 27MP capture mode in general use-cases, while OnePlus had opted for a slightly smaller 1/1.4” sensor in the OnePlus 8 Pro with a 48MP native resolution, binning down to 12MP.

The big caveat with these big sensors is their optics systems – many times the plastic lenses can’t keep up with the resolution of the sensors, partly negating some of their characteristics, making much of the 108MP contenders relatively gimmicky in real-world scenarios.

iPhone 11 Pro vs Galaxy S20 Ultra

The other big issue with larger sensor sizes is that they require a larger z-height of the camera module, which means larger camera bumps. And oh boy, we did get some really funky looking camera bumps in this year’s devices, such as the massive design element on the S20 and Note Ultras.

120Hz, An Almost Must

Another big development this year has been the mainstream adoption of high refresh rate display panels. While in 2019 90 or 120Hz displays were exotic or reserved for special gaming-oriented phones, in 2020 it could be said that it was a checkmark feature for almost every vendor, essentially eliminating 60Hz from almost all new product releases bar the mid-range or low-end.

Though 120 and 90Hz displays this year certainly have augmented the fluidity and user experience of flagship devices, only the Note20 Ultra was the one device which was able to adopt this with relatively few drawbacks, thanks to its new polycrystalline and oxide panel technology. For the rest of the market, 120Hz came with a relatively larger battery impact, meaning the new fluidity came with a device longevity compromise.

For 2021, I see more vendors adopt the new 120Hz feature in a more optimised manner that improves upon the battery consumption, maturing the technology to a point where it becomes a no-brainer to have it enabled by default.

Exynos Core Death (& Revival?)

Continuing with our takes on key hardware component changes in 2020, one large move has been Samsung’s abandonment of their custom CPU cores in their Exynos chipsets. Struggling with power efficiency and performance competitiveness for several years now, Samsung LSI finally cut the cord on their custom CPU core design project and team, opting to instead fully rely on Arm’s future Cortex CPU IP for next-generation Exynos SoCs.

We had been covering Samsung’s cores in detail for several years now, and it’s unfortunate to say that the project’s cancellation is likely the best-case scenario for future Exynos SoCs, dropping one of the chip’s most negative aspects – and in turn likely result in significantly better designs in 2021, hopefully eliminating some of the performance and power efficiency differences between Snapdragon and Exynos Galaxy phones.

MediaTek Dimensity Resurgence

2020 marked MediaTek’s re-entry into the high-end SoC market, introducing the new Dimensity 1000 SoC. Although the new design was off to an extremely slow start with very few design wins in the first half of the year, the company’s efforts in the mid-range Dimensity series has results in a large amount of design wins, and according to Counterpoint Research, allowed the company to actually position itself as the #1 SoC vendors in Q3 2020, taking market share from the likes of Qualcomm.

We had reviewed the Dimensity 1000 inside of the OPPO Reno3 5G and found it to be an excellent SoC in terms of performance and efficiency – what’s really lacking though is a more prestigious high-volume design win that has more visibility. Hopefully MediaTek manages to achieve such a design in 2021.

5G for Most

While 5G has been a premium “the new thing” feature in some 2019 devices, it can be said that it’s really in 2020 where the new cellular communication standard has really been adopted as a mainstream technology in new smartphone products. Almost every new Android flagship device has had 5G as a selling point in 2020, and with Apple’s release of 5G-only iPhone 12 series, we can pretty much say we’ve made a turning point between 4G and 5G.

Although cellular networks in many countries are still in deployment and it’ll probably be a few years before 5G becomes ubiquitous for everybody, buying a 4G device today is no longer the best long-term investment unless you’re really looking at low-end devices. 5G also has trickled down to the premium and mid-range thanks to the likes of SoCs such as the Snapdragon 765 – with 2021 projected as being the year where we’ll also see the $250 device market also adopt 5G connectivity.

    When you shake it all out and consider actual camera results (that are flagship) and the flagship Android software experience, it's Pixel 4a 5G @ $499 for the win.

    My 3 pet peeves got unadressed though:
    1- not easy to perform basic maintenance, ie change the battery and screen. Screws are not Sci-Fi tech ! (I blame mostly Apple)
    2- Ever longer and narrower screens, as if anything above 16:9 had any use case. Not videos. Not reading. Not maps. Not games. Not Office. Instagram I guess ? That's a lot of us suffering for one measly use case.
    3- there are still phones with non-flat screens, no SD slot, no jack, only 1 SIM slot or a shared SIM/SD slot. Especially at the high end: good, this kills any desire I had to move back upmarket.

    You can rightly blame Apple. And if other companies start mandating that parts be flashed a certain code before installation using a tool only available to themselves, you can blame Apple again.

    Apple doesn’t tell other vendors what to do. Every vendor is responsible for their own decisions. If they’re all visionless, spineless followers who do what their bean counters tell them to, then they each should be seen as accountable for their decisions.

    ...So in other words, Apple is the master prophet of bean counters.

    Negative Trends I've observed in the industry:

    - Marketing is Paramount (many companies deciding to expend more focus on marketing, such as buying reviews, making shiny renders, confusing ads, or heaps of buzzwords. Even if it comes at the expense of the phone capability and experience)
    - Increased Cost (many price rises are just following iPhone X/Max, and aren't really justified)
    - Reduced Serviceablity (curved front and back, using glass, getting heavier, means durability is down. Locking down parts is horrendous)
    - Audio compromised (no front-firing stereo loudspeakers, no headphone jack, BT in-ear sets pushed down consumers throat)
    - Loss of features (microSD, DualSIM, LED light, IrDa blaster.... they're a niche now)
    - Larger and larger sizes (what is deemed "medium" now is about equal to what was deemed "large" only a few years ago. There are no small flagships outside Sony/Apple)
    - Battery Life taken back (loss of User Removable Battery for sealed batteries, compromised made to make phones waterproof but most phones aren't and don't have an IP68 rating, capacities took a long time to progress, extra efficiency gains show very little effect in real-world use, new-generation software possible culprit)
    - Software still abandoned (Apple is gold standard. Google fluctuates, Samsung's improving, but most phones still get left behind in terms of security, features, etc)
    - Cameras are sticking point (one large sensor will beat many small sensors, but that sucks for marketing. Sensor sizes have started to go up finally. And computational photography has matured. However, many mid-range phones are still following trends instead of good photo performance)

    ....these trends are a fantastic thing for companies, not for consumers, as it means youre more likely to buy, spend more money upfront, forced to buy more accessories, more money on servicing, and need to upgrade sooner.

    I think we peaked in 2014-2016 (Samsung Note4, iPhone 6S+, Samsung S7+). The only solace is this year's excellent duo from Sony in the 1.2 and 5.2, which really is a "no compromise" experience. The area they did compromise in was Marketing, and that continues to hurt their profitablity... so this could be a one-off.

    Good points.

    People get too wrapped up in the specs, especially in forums like this. Take the camera for example. Yes, bigger sensors are better, but at the end of the day, the total camera system is what gets measured, not just the sensor. The quality of the lenses, the quality of the ISP and the computational photography capabilities, etc. all play a big part in this.

    For years, many of us have known that things like microSD cards and IrDA blasters were rather useless in reality. The spec counters will fight this until their dying breath, there are good reasons to get rid of these "features".

    I do agree with your point about how medium sized phones today are what the big phones were previously. In order to cram in larger batteries, more cameras, etc. vendors have had to go this route. For me, the pendulum is starting to swing the other way. I don't like a big phone in my pocket. I may go for something like the iPhone 12 mini next time.

    > the total camera system is what gets measured, not just the sensor
    I'd like to believe that, but low quality oversharpened crap still dominates. Look at Apple, they still bake aggressive NR and sharpening into their so-called "ProRAW". That goes against both "Pro" and "RAW". Going high on the sensor size and pixel pitch almost certainly guarantees that the image quality goes in the right direction, tricks like "Nonacell" can't be relied on and are only somewhat useful in generating oversharpened crap.
    And Google, Pixel 3 was the height of Pixel's image quality on automatic settings, it regressed from there to push for stronger automatic HDR at the expense of resolution.

    >like microSD cards and IrDA blasters were rather useless in reality
    The point is they're good to have, cost almost nothing to retain, and their removal only benefits the manufacturer. Moreover people who pay more deserve more functions. This should stand within a certain category of products. There are no "good reasons" to remove them in flagships except for profit and that alone. Currently, consumers are basically deprived of the smartphone equivalent of the laptop workstation, the closest would be the LG V series(just discontinued, we'll have to see what follows) and Asus ROGP series.
