Samsung A73 5G – the pick of the 2022 A-series (smartphone review)

The Samsung A73 5G is the definite pick of its 2022 A-series. Not because its lower-cost siblings, the $599 A33 or $699 A53, are not good too, but because this model does everything very well in a no-ifs-and-buts way – it is a very capable phone.

Our Samsung A53 5G – a decent 5G smartphone for $699 (review) scores 8.7/10. The Samsung A73 5G has a larger screen, is slightly thinner/lighter weight, has a 108MP primary camera, better processor, and Wi-Fi AX – way more value than the extra $100 denotes.

We are also retesting the $1849 Samsung Galaxy S22 Ultra and using that as a reference. The $799 Samsung A73 5G is more than a match in so many ways that we are suitably impressed. It has our unreserved buy recommendation.

To explain – we review via price brackets – $700-799. We look at what we expect these devices to do. The Samsung A73 5G exceeds many of those parameters and is nipping at the heels of the $999 Samsung Galaxy S21 FE, Fan Edition (review) that costs two hundred more. We think using the Qualcomm SD778G 5G system-on-a-chip (SoC) gives it the operating edge (not raw speed) over the Exynos 1280 in the S21 FE.

New Deep-Dive review format

It is now in two parts – a five-minute overview for most readers and a separate 300+ line database-driven spec including over 70 tests to back up the summary. It also helps us compare different phones and features.

Note that we use Fail (below expectations), Pass (meets expectations) and Exceed (surpasses expectations or is the class leader) against many of the items below. We occasionally give a Pass ‘+’ rating to show it is good but does not quite make it to Exceed.

Watch out – buy genuine if you want 5G to work here

We issue a strong warning that you must buy a genuine model with Australian firmware if you want to use 5G. Read Don’t buy a grey market phone to ensure you get the Australian ‘B’ model (SM-A736’B’ and /DS for dual sim.

It is easy to identify the Australian version – usually, under Settings, About Phone, Legal Information, and Regulatory compliance, you will see the Australian RCM C-tick mark.

Models to avoid are any other colour, single sim, 8GB or larger than 128GB storage. If you receive a shrink-wrapped phone, it likely will not work on 5G here.

First Impression – Classy in Awesome Grey and fun in Awesome Mint – Pass +

I don’t mind plastic backs (or PPMA glastic – whatever you call it), but this matte Awesome Grey is classy, and the Awesome Mint looks fun but more inexpensive. They are not so much a fingerprint magnet as a greasy finger magnet.

The faux chrome plastic frame looks good, but it can mark easily, so buy a bumper cover. The screen is reasonably scratch-resistant Gorilla Glass 5.

It is thin and light at 163.7 x 76.1 x 7.6 mm x 181g.

Screen – 6.7″ 2400 x 1080, 60/120Hz, 8-bit 16.7m colour AMOLED – Pass

Samsung quotes 800 nits, but that is HBM (high brightness mode). Frankly, that is a marketing hype measure of a ridiculously small percentage of the screen at maximum brightness to enable it to claim HDR10/+ support – not at all realistic. The screen is closer to 400 nits at maximum automatic exposure and, in most use, between 230-300 nits. In fact, HDR10/+ content downscales to the screen capability, as does Netflix, that only offers SDR content (pretty typical).

It also claims 120Hz refresh (true), but it is either 60 or 120Hz – not adaptive as many OLED screens are. The latter refresh rate has a significant 30% hit on battery life.

On the plus side, it is relatively colour accurate (offers Natural sRGB and Vivid DCI-P3) as well as basic colour temperature and RGB adjustments.

Summary: Nice basic AMOLED screen, but it would have been so much better to have an adaptive refresh rate.

Processor (SoC) – Qualcomm SD778G is the Goldilocks SoC – Exceed

You can pretty well guarantee that any SD778G smartphone (OPPO Reno 7, realme GT/9, Vivo T1, Motorola Edge 20, Samsung A52s and nearly 80 models) will perform well. No, it is not flagship-class – but it closely matches the 2020 flagship SD865.

The Samsung A73 5G had no throttling (excellent) and plays PUBG: New State Mobile at 60fps maximum frame rate in 120Hz Games Mode with 6+6GB (RAM and virtual RAM). This means you can borrow up to 6GB from storage for swap space.

Storage read/write is 563/91MBps, typical of UFS 2.2, and the MicroSD card is 89/19MBps – plenty fast enough for 4K video.

Comms – adequate, but the SoC is capable of far more, so why not use it? Pass(able)

The SD778G SoC offers

  • Peak Wi-Fi 6 AX speeds of 2800Mbps VHT160, but this maxes out at 480 (fewer Wi-Fi streams and VHT80 only)
  • USB-C 3.1 but only implements USB-C 2.0
  • BT 5.2 but only appears to implement 5.0
  • Dual-band GPS but only appears to implement single band

Simply put, these are cost-saving compromises so as not to get too close to the S21 FE model.

Phone – brilliant for city, suburbs, regional and rural use with one caveat – Exceed

Not only did it get signal strengths to 16pW (excellent), but it found the nearest four towers (excellent). But there is one issue you need to be very aware of. The phone antenna is at the bottom of the phone – where you may typically hold it. If you cover this with your hand, signal strengths are very average. To be clear – hold the phone in the middle of the frame.

Battery – two days easy – Exceed, but no charger supplied. Fail

The 5000mAh battery will last two days of typical use, maybe one with heavy use. The video loop test (50% screen brightness/volume, aeroplane mode) was excellent at 21 hours 20 minutes.

PC Mark 3 battery test (typical use) was 18 hours and 58 minutes, and Accubattery verified this at 18 hours. Heavy screen-on use (GFX Benchmark Manhattan and T-Rex) were 6.15/10.55 hours. 100% load, screen-on discharge from 100-0% is 4 hours and 6 minutes.

But Samsung loses points (and it will continue to do so as it slavishly follows Apple) with no charger in the box and an underrated 2W cable (you need 3W to get a fast charge). It also uses 9V/2.77A, standard on Samsung 25W chargers, but the PD standard is 9V/3A, so most third-party USB-C PD chargers drop back to 9V/2A/18W or 5V/3A/15W charging. Charge time at 25W is 1 hour and 18 minutes, and 15W is nearly 3 hours.

Sound – pretty good – Pass+

It uses the same dual Cirrus Logic CS35L41 amplifiers, each 5.3W, 1% THD, 8 ohms, as the Samsung Galaxy S21 FE and S22-series.

This gives excellent volume (85dB), and the speakers have a warm and sweet sound signature suitable for most music. It has Dolby Atmos decode/downmix to the stereo 2.0 speakers and a nice wide sound stage.

Hand-free is quite a step up from the A53 with dual microphone noise-cancelling and sensitivity, although it is not quite as good when recording video.

As it is a Qualcomm SD SoC, it supports SBC, AAC, aptX and LDAC, but the whole aptX suite (low latency, high def) has been left out to save costs. We tested with aptX and LDAC headsets (high res), and it was superb.

Build – Pass

Earlier, we commented that the faux chrome-plated plastic (polycarbonate) frame was prone to scratching. Over the four-week test (while taking extreme care to keep it in a separate pocket away from keys etc.), it picked up marks. Please buy a cover.

And in good news, Samsung now offers a 24-months warranty matching class-leaders OPPO (its main nemesis).

Missing – Fail, but should you care?

If we don’t keep telling Samsung that no charger in the box is a deal-breaker ($29 from Samsung plus an extra cost of a 3W cable), then it will never change.

It does not have

  • 3.5mm jack (no big deal as Bluetooth and USB-C/3.5mm DACs are cheap and good)
  • Wi-Fi 6 proper implementation (480Mbps is slow)
  • BT 5.2 proper implementation (would provide multi-point connections)
  • USB-C 3.1 proper implementation (would allow Alt-DP audio/video external screen)
  • Adaptive screen refresh
  • GPS dual-band proper implementation
  • Additional side or top phone antennas
  • More Qualcomm BT aptX codecs
  • Buds and bumper cover (no big deal)

Despite these things, Joe and Jane Average will not notice, will love this phone, and be blissfully unaware that similarly priced phones have it all.

Operating system – up to four years of upgrades and five years of security patches – Exceed

Samsung’s policy makes owning one better and more secure for longer. That means Android 12 may reach Android 15! But we were disappointed that the security patch was February for a June review (most competitors are at May).

One UI 4.1 is a light touch over Android and allows for its Samsung customisations. But we are growing more concerned at the need to sign up for a Samsung Account to access anything in its Theme or Galaxy App store – it is bad enough that Google knows all about us.

Our advice is not to use Samsung apps that substitute for Google ones, especially if you brand swap and want seamless changeovers.

Samsung A73 5G Camera – Pass+

True, 108MP gives Samsung bragging rights, but in practice, this Samsung SK5HM6 Nonapixel RGB Bayer Pattern combines 9 pixels (3×3) to create a 12MP image. The image quality also depends on the AI capability (12 TOPS compared to 26 for the S22-series). Overall, it’s a great sensor that produces better-than-average daylight shots.

We found:

  • OIS is on the primary 108/12MP sensor only and works well
  • Daylight: Good natural colours and lots of details in shadow and highlights
  • Ultra-wide: lacks dynamic range and is a different colour. It uses a considerably older (September 2015) 13MP Sony IMX258 sensor, which we put down to COVID-related parts shortages. It gets very grainy on zoom
  • Zoom: forget it past 2X, and 10X zoom is unusable
  • Office light: Natural colours, fast focus, good dynamic range
  • Bokeh: Severe default blur but can be adjusted
  • Macro: We tried several shots, but all lacked the precision focus we like
  • Dark <40 lumens: Pretty good colour and detail
  • Night <40 lumens: Refines the image and adds a little more highlight. It is not up to Samsung’s S22-series Nightography that has far more AI power
  • Selfie – 32MP bins to 8MP offering a decent quality selfie in day or office light
  • Video – 4K@30fps is fine. 1080p with OIS is superb. Voice recording is average

CyberShack’s view – At $100 more than the A53 5G, the Samsung A73 5G is the pick of the litter

Our reviews are objective – we run over 70 tests and don’t read press releases or review guides that are much regurgitated as part of 99% of the other reviews.

So, there is no malice in telling it like it is; frankly, this phone will rate better than the $699 A53 and $999 S21 FE. Why? Because in the $700-799 bracket, it is pretty good, and Samsung is a safe bet.

Competition is quite fierce, and we note other phones you should compare it with

  • OPPO Find X5 Lite $799 has 8/256GB and fast 65W charging (supplied). Its primary camera is 64MP and binned to 16MP, and its photography tech is better.
  • Motorola Edge 30 Pro ($999 but on special at $799) has the latest Qualcomm SD8 Gen 1 SoC, Wi-Fi 6E, 30W charger in box (68W capable), Adaptive OLED screen and decent twin 50MP camera.
  • Motorola Edge 20 Pro (2021 run-out) $899 but on runout at $719
  • Samsung S20 FE (2021 run-out) at $699

They are all good phones, but Motorola Edge 30 Pro must be killing all comers in this bracket with the special price.

CommentThe SD778 5G is one of those Goldilocks SoCs. Not too hot, not too cold, but just right. It has heaps of power, reasonable game performance, good battery life, and enough AI TOPS to ensure great point-and-shoot photos.
Videographers and vloggers will soon run out of space without mountable storage, seen as internal storage.
