Samsung’s new Galaxy S8 is hitting stores this
week and it’s bringing a lot features, design,
and screen along with it. The S8 (and its
larger sibling, the S8 Plus) is one of the best
phones ever made and the best phone you
can buy right now, read,full review https://www.theverge.com/2017/4/18/15328968/samsung-galaxy-s8-review-s8-plus.
But if you’ve already ordered or bought an
S8, you might be wondering what the best
way to unlock it is. Because unlike Samsung’s
prior phones, the S8 doesn’t have a
fingerprint scanner on the front. Instead, it’s
on the back of the phone, near the camera.
This can present issues with comfort (it’s hard
to reach) and practicality (you’re very likely to
put your finger all over the camera lens
when trying to use it).
So Samsung has introduced a total of five
ways to unlock the S8 to make up for the
poor fingerprint scanner placement. Which
one’s the best? Let’s break it down.
PIN CODE / PASSWORD
As with every other smartphone, you can use
a four-digit PIN code or alphanumeric
password to unlock the S8. These are the
most secure methods to use, but they are
also the most inconvenient and clumsy. When
you unlock your phone hundreds of times a
day, it gets very tiresome to type in a PIN or
worse, a password, every time.
PATTERN
The S8 also supports the standard Android
pattern unlock method, whereby you trace a
particular line you set through a grid of nine
dots. This is the way most Android owners
unlock their phones, as it’s more convenient
than a PIN code or password. It is slightly less
secure than those options, but still
considered one of the more secure methods
to protect the information on your device.
FINGERPRINT
As mentioned, the S8 does have a fingerprint
scanner and you can use this to secure and
unlock your device. Unlike other devices, such
as the Google Pixel that put the scanner in
the middle of the phone where your index
finger naturally rests when holding the
device, the S8’s scanner is high up on the
back of the device and not in the middle.
That can make it very hard to reach,
especially with the larger S8 Plus, and it can
be more difficult for left-handed people that
have to move their index fingers awkwardly
to cover it.
To make matters worse, the fingerprint
scanner is right next to the camera, and
“feels” very similarly. So if you’re moving your
finger around trying to locate the scanner by
touch, it’s very easy to smear the camera
lens with fingerprints and oils, which is not
particularly pleasant. (Why is it there, you
may ask? Samsung says it’s because the
location of the battery inside the phone
prevented it from being placed lower down.)
All of that said, the fingerprint scanner is a
secure method, and the actual scanner on
the S8 is very fast. My colleague Walt
Mossberg had trouble getting it to register his
digits, but I’ve had no issues with it waking
and unlocking the phone with my fingers,
provided I can actually reach it. I’ve adjusted
a bit after some time with the phone, and
find myself using the fingerprint scanner a bit
more than when I had first picked up the S8.
But it’s still annoying and something I have to
think about doing, instead of it just
happening naturally when I pick up the
phone.
IRIS
To make up for the S8’s bad fingerprint
scanner placement, Samsung has included an
iris scanning method, which uses special
sensors on the front of the phone to identify
you and unlock the device. Iris scanning is
considered one of the most secure biometric
methods we have available, and you can use
it for everything from unlocking the device to
authenticating purchases with Samsung Pay.
But iris does have its downsides: though it
works in low light, it can have a lot of trouble
recognizing my eyes in sunlight, and I have to
hold the phone up and awkwardly close to
my face. It also can have trouble with glasses
and takes a second or two longer to
authenticate compared to the fingerprint
scanner. My colleague Vlad Savov found this
to be the easiest way to unlock the S8 Plus in
his time with the device, but again, Walt had
trouble with it seeing his eyes.
FACE
The newest means of unlocking the S8 is
Samsung’s new Face unlock feature (not to be
confused with the face unlocking feature
included in Android since 2011). This method
uses the front-facing camera to identify you
and unlock the device. It’s designed to be the
most convenient way to unlock the phone,
but it is less secure than any other method
and cannot be used to authenticate Samsung
Pay purchases.
In our tests, the Face unlock method was the
slowest and least reliable way to unlock the
S8. Despite promising to work at various
angles and from comfortable distances, this
method refused to work the vast majority of
the time. It would not see my face in good
light or poor light, and when it did work, it
would take several seconds of awkwardly
staring at the phone before it would unlock.
To make matters worse, some have been
able to trick the Face unlock feature with a
picture, proving its lack of security. I was not
able to replicate this, for, as I said, it
wouldn’t unlock with my real face anyways.
So of all these options, which is the best?
I’ve settled on a combination using pattern,
fingerprint, and iris methods, all of which can
be enabled at the same time. I find myself
most often using the fingerprint scanner,
which both wakes and unlocks in one motion.
But if I can’t reach it, the iris or pattern are
the fallbacks I use.
Either way, it shouldn’t be this difficult to
figure out a simple task such as unlocking
your phone and we hope that Samsung uses
a better design for its next device.
