Samsung makes good phones. The Samsung Galaxy A70 packs so much into a mid-market device that it is a great phone.
Samsung has a reputation as ‘king of the heap’ in the Android flagship world. Rightly so as over the past few generations, it has focused on innovation as well as reliability. It was early to include IP ratings, Qi charging, multi-cameras and huge screen-to-body ratios. You can’t go wrong. The Galaxy A70 proves this again.
But while all its attention was on its premium flagship
Galaxy S-series, it lost ground in the mass-and mid-market. And it hurt as
Huawei’s Nova, Motorola’s G-series, Nokia’s everything, OPPO’s R-and-A-series, and
others ate Samsung’s lunch – and then some.
DJ Koh, President and CEO of IT & Mobile Communications
Division at Samsung Electronics knew it would take something special and he vowed
to bring many Galaxy features to the lower-cost A-series. The result is a range
of Galaxy A-series phones that are winners in every segment.
The Galaxy A-series range
Just released overseas is the Galaxy A80 with an innovative rotating triple camera – you have the same quality lenses and shots front and rear. When it gets here, we will be first in line to review it. And a Galaxy A90 may make its way here too. The Australian line-up of the Galaxy A-series includes:
A70 Website $649, 6.7-inch, Super AMOLED, 32+5+8MP rear camera
A50 Website $499, 6.4-inch Super AMOLED, 25+5+8MP rear camera
A30 Website $379, 6.4-inch Super AMOLED, 16+5MP rear camera
A20 Website $279, 6.4-inch Super AMOLED, 13+5MP rear camera

How we rate smartphones
We develop comprehensive paradigms – what must a phone in a certain price category do? That way it avoids odious comparisons with other brands. Our original four categories have grown to seven.
Premium Flagship $1600-2499 (usually a flagship
with more memory/storage, additional camera lens and now 5G)
Flagship $1000-1599 (account for about 10% of
Premium mid-market $800-999 (10% and often last
year’s flagship at run-out price)
Mid-market $500-799 (about 25% of the market)
Mass-market $200-499 (about 25% of the market)
Value pre-paid <A$199 (about 30% of the
market – good for pre-paid and children)
The Galaxy A70 sits in the mid-market about $150 below the
top of the category. It directly competes with Google Pixel 3a and the slightly
more expensive Nokia 8.1, Google Pixel 3a XL, Samsung S9 (runout) and LG V40
The A20, A30 and A50 are in the mass-market segment. These variously compete (in order of price) against LG Q6/Q7, OPPO AX5/AX7, Huawei Nova 3e/i, Nokia 4.2, Huawei 3i, OPPO AX7/R11s, Huawei P30 Lite, Nokia 7.1 and OPPO Reno Z.

We issue the standard warning that you must buy the genuine
model with Australian firmware as it works on all Australian Telco carrier LTE
bands, has Australian signalling (for accurate billing) and can make a
000-emergency call (not 911) without a SIM. These also work with Australian PayWave

The Galaxy A70 first impression
You first notice the huge (6.7-inch), vivid, full 2.5D curved edge, flat Super AMOLED screen with very narrow bezels all round and a teardrop notch.
The back has a shifting hue material called Glasstic, and yes, it is a fingerprint magnet. It has a bottom-firing speaker, a 3.5mm headphone jack and three cameras (in the upper left).
Overall, it is a full screen (86%) glass slab, elegant enough and slightly taller and narrower (20:9 screen ratio) than most phones. It raises the bar enormously over Samsung’s previous mass-market (non-Galaxy) A and J models.
Resolution: 2400 x 1080

The Qualcomm SD675 is a fast, mid-range eight-core processor
with an emphasis on power when you need it. The new 11nm die is LPP (Low Power
Plus). It is in the new Motorola Z4 as well – this would normally have an SD855.
It allows six efficiency cores to run from a very low 300Mhz and two up to
2Ghz. In idle mode it barely sips power.
There was no evidence of throttling under a 100% load stress
test, and all cores maintained a consistent maximum GHz rating – excellent. The
temperature under load was 37° near the camera.
It is faster than the 2017 Qualcomm SD835.
GeekBench 4 single/multi-core test is2367/6554 with an overall 5901 Compute score. To put this in perspective, it beats a Samsung Galaxy S8.
It’s fast, smooth and not laggy even with multiple apps
The Adreno 612 has an emphasis on good colour and screen
performance, not so much games. Older mobile games to 30fps are fine, and you
may be able to play PUGB.
Wi-Fi signal strength is -55dBm and among the strongest
tested to date. That means it will hold onto 5Ghz signals further from the
NFC supports Samsung Pay and Google Pay. You don’t often get
this in mid-range phones.

It has no bass and low range mids leading to strong mids to upper highs making
this bright vocal. That means a clear and crisp voice, but it can be shrill for
music and movies.
You can play with the equaliser, but frankly, the single
internal speaker is incapable of adding more bass or mids.
The device is capable of high-quality BT and 3.5mm output in
stereo (or more).
It also has ‘adapt sound’ to emphasise certain frequencies
over headphones – Under 30 years old (favouring bass), 30-60 years old (favouring
mids) and 60+ (favouring mids-higher frequencies).
We tested the 3.5mm buds – themselves a curiosity these days,
and the sound was adequate. For better sound, buy better quality cabled buds.
Using our reference, Sony WH-1000Xm3 headphones and the aptX
(not HD) sound was great. The sound stage was wide and separation excellent. The
‘adapt sound’ pre-sets make quite a difference to our Sony headphones but no
more so that the Sony pre-sets themselves.

An under glass fingerprint sensor is as yet unheard of on a mid-range device. It’s a bit finicky, but you get used to it. I prefer Face Recognition, which is fast and accurate.
GPS use was excellent for a mid-range device with not one missed turn and adequate announcement notice.

The battery is very large for this class of device. Coupled with the power-sipping SD675 can produce some amazing battery statistics.

Given typical use we
expect this to run for 24+ hours between charges.
The signal reception was very strong and up there with those
with a Telstra Blue Tick for regional use; -83dBm compared to the reference Samsung
Note9 of -95dBm (lower is better). It also located the next nearest tower at
-111dBm – excellent.
It appears that only the single sim version is for Australia.
One UI: 1.1
Galaxy special apps including Samsung Pay, Bixby, Camera, Health,
Google apps (all) plus Lens, Assistant
Spotify, Netflix, Facebook, and Microsoft apps
Android Pie has loads of features, including AI, to learn
about your use and adapt the phone to it. In the test week, we started to see minor improvements, but we would not expect
to see Pie AI kick in for a month or so.
I like Samsung One UI. It is a light touch over Android 9
(and 10 etc) and is a bit like the grease on the wheels. It smooths over the
rough edges of pure Android and works flawlessly. It adds things like night
mode and dual app use.
Bixby is Google Assistant’s access to the phone. It has been
beefed up for countries where Google is not available.
The phone has Knox 3.3 protection, including secure folders with
face recognition access.

Plastic frame with Glasstic shatter resistant back.
Good rigidity – no #bendgate here
164.3 x 76.7 x 7.9 mm x 183g
Few mid-market phones have an alloy frame, and the plastic frame
resists all attempts at bending.
Glasstic (Wiki article here) is a marketing word for a mix of organic polymers and non-crystalline amorphous solid glass that gives it high plasticity (deform without breaking – high shatter resistance) rather than glass that will shatter, break and flake off.
It has approximately the same Mohs hardness scale as glass (approx.
6-7) on a scale of 0-10 (higher is harder), so it should wear as well.
Gorilla Glass (a mixture of alkali-aluminosilicate and
glass) trades off between scratch resistance (GG 4/5 has a 9 rating) and shatter
resistance (GG 6 has a 6-7).
Bottom line – it could be a good idea to use a bumper cover.
An IP rating is not an invitation to go swimming – it is for
accidental drops in the toilet and to protect in inclement weather. Because of
the design (all bar a microphone hole is in the base and the fused construction
means this is perfectly fine if caught in the rain.
It is a shame there is no notification LED but it has an
Always On Display Lock Screen that more than makes up for it.

5MP depth and live focus
It is a triple camera, but, the 5MP is just for depth (bokeh
and live focus). You have a standard and an ultra-wide lens that you select
from (two trees or three trees icon).
The 32MP sensor has small .8um pixels. While that is good
for fast focus and low noise, it does not capture the light that larger pixels
do. So, it does what the Google Pixel does – pixel bin (stack) to give a
significantly larger 1.6um pixel size equivalent and saves as a 12MP file. It
works well in daylight and office light and adequately in low light.
You can shoot in 32MP for exceptional detail, but you lose HDR, and it has slower focus and a couple of seconds for post-processing times.
The same 32MP sensor is also on the selfie lens and defaults
to pixel binning and 12MP.
It has an extensive range (20) of scene optimisers, flaw
detection (detects blinks and blur), AR emoji etc.
Tests – all auto
Perfect colours and detail. Scene optimisation detected Blue Sky – it made little difference to this perfectly exposed shot. HDR is automatic.
We also shot in Ultrawide, and as expected with a 123° FOV,
it produces curved images towards the edges.
Indoors Office Light (400 lumens)
definition and detail.
Low light (room with less than 100 lumens)
Colours were adequate, but the details were missing. Too
much blow out on the computer monitors. Low light is its weakness, and we
suspect Samsung will be working on firmware updates to correct this. It also
lacks night mode.
32MP means lots of detail, but the camera defaults to 12MP (pixel binning). If the light is good you will get great detail and good colours – an above an average selfie. The lack of fill light or flash means lower light selfies are not on.
It also has normal and close modes – the latter is just by cropping
the centre 8MP from the 12MP image.
The 5MP lens captures good depth information an enables post-processing
to adequately separate the foreground from the background. The same caveats
apply – it works really well in good day and office light and misses the mark
in lower light.
It will do [email protected], but in our opinion, it is pushing the capabilities
a little too much in anything but good daylight. Where it excels is [email protected] or
30fps (where EIS kicks) in, and you can’t fault colour or detail in a good
For a $649 phone its
excellent. It has a weakness in low light, but despite this its more than you can
expect for the money.
GadgetGuy’s take _ Samsung is on a winner with the Galaxy A70
While reviewing the Galaxy A70 I kept reminding myself it is a $649 device, yet it has features that cost a lot more in other devices. If we rate this as a mid-range device, it is 5-out-of-5 – hands down. It loses a point here or there because of low-light camera performance, and it should have an IP rating – even if it’s very low.
Samsung is on a winner
here. It is by far the best mid-range yet. You buy it for a reasonable camera,
great battery life and that huge screen – in fact, the largest AMOLED on the market.
It has a great
mid-range Qualcomm SD865, terrific performance and Samsung quality. It is for
those who want an immersive AMOLED screen.
The Galaxy A50 uses a similar camera setup, but the processor is a Samsung Exynos 9610, and we are yet to see how that compares in post-processing power. We suspect it is similar the SD675. The A50 at $499 may be the sweet spot and sits in mass-market pricing.
