okay truth bomb time I honestly didn't think we would be the first smartphone
brand in the world to actually showcase a phone with an in display fingerprint
scanner that feat in itself deserves an applause of its own
now the we were x21 with all the you D suffix has launched in India finally and
I'm glad that mr. phone got an opportunity to actually test it out
before the launch so what are you waiting for I am ershad mr. from phone
and let's get down to my full review of the vivo x21
Hey stop it right there don't forget
subscribe to our Channel I think the by liking to get notified
for more such awesome tech videos before we start this review so since the in
display fingerprint sensor on the VEVO X 21 is the most important feature of the
phone let's talk about it a little bit first so how does this technology
actually work essentially a sensor just like your camera sensor sit 0.68
millimeters below the display substrate so the moment you press the designated
area and register your fingerprint the sensor captures reflections of your
fingerprints through the OLED pixels and that is how it can actually recognize
your fingerprints so thus we will make these in display fingerprint sensors no
actually the under display fingerprint sensors are made by this company called
synaptics it has a module called synaptics FS 9 5 double zero clear ID
which is used under the display the most important question that might be on your
mind is how long does it take to actually unlock the phone using an in
display fingerprint sensor well in my experience it takes a little bit about
0.7 to 0.8 seconds to unlock the phone which is definitely not as fast as you
know apples touch ID or any other physical fingerprint sensor for that
matter but hey this is first generation tech we're talking about you know touch
ID wasn't as fast as it is today as it was on the iPhone 5s
husak so can the entire display turn into a fingerprint sensor interestingly
yes you actually has a concept phone called the apex which uses the entire
bottom half of the phone to register your fingerprints in fact that phone is
actually going to be in commercial production soon and will launch as the
next later this year sometime but the thing that you have to note about using
the entire display as a fingerprint sensor is that that tech is not gonna be
cheap it's gonna be a little more expensive so does the industry
fingerprint sensor work underwater yes it can work under water but the V works
to anyone is not waterproof so don't try that at home does the ink
display fingerprint sensor work with the screen guard on yes it does work with
the screen guard on and in fact the viewer at 21 falls to the pre-applied
screen guard and I tested it out and it works just fine
can you use the fingerprint sensor to lock any app so as to protect your
privacy yes you can do that check this out
moving on setting up the fingerprint takes longer than physical sensors when
the setup process asks you to hold the edges of the finger and show that you
tried different angles also it is really vital that you keep your fingers
during the detection process follow these steps diligently and the scanner
will have a much lower fail rate I learned it the hard way
moreover you really need to press deeply for the sensor to identify your prints
thankfully the phone vibrates if the fingerprint is not registered and
therefore you don't have to second-guess also you get three different types of
fingerprint unlock animations that you can choose from if you do struggle with
the index play fingerprint sensor you can opt for face unlock instead and vivo
uses an infrared based sensor for unlocking the phone this is cool because
it unlocks really fast almost as fast as the one plus six and it feels secure too
moving on at the moment in the split fingerprint scanners play nicely only
with a male tech and I'm not really complaining because the six point two
eight inch 19's a 9 aspect ratio panel is actually bright colorful and crisp
for most scenarios it is a full HD panel in fact the blacks are so deep that the
always-on display looks as impressive as Samsung's flagship Galaxy S line don't
get me wrong though Samsung's displace are still the best in the business
no bleeding that moreover in bright light you can actually see the embedded
sensor very clearly when you crank up the brightness I don't necessary think
of it as a distraction but I hope that display tech improves in the future to
eliminate this issue all in all the display on the X 21 is where all the
action happens and the in display fingerprint sensor is actually magical
for nerds like me at least having said that it is not as fast and it leaves a
lot of refinement as well as far as the design of the Revo X 21 is concerned it
looks nearly identical to the vivo v9 however there are subtle changes that
make a whole world of difference but negatively and positively firstly the X
21 is actually made of glass and not plastic
therefore it adds a bit of heft making it easier to hold
despite the slimmer 7.4 millimetre profile the most annoying thing about
the design is the fact that we were is persisting with a microUSB port instead
of a type c1 actually the use of glass the phone is slippery but the Black
Radiance Center mr. phone was not as big of a smudge magnet as I expected it to
be that's a good thing vivo also burned is a really good looking case inside the
box one that needs no replacement the minimalistic rear of the phone sans the
fingerprint reader makes it pretty attractive also interestingly we go has
put the SIM card tray at the bottom edge this hybrid grey accepts two nano SIM
cards and you can swap out one SIM card for a micro SD card if you wish to solve
the design of the vio x21 it is a shinier
buckle your twin off the vo v9 and it is bound to get all the attention
like the v9 the x21 also runs fun touch OS 4.0 on top of android 8.1 yep it is
still a copy of iOS and I've spoken about it in length about what I like
what I don't like in my v9 review which should be up in a card somewhere over
here that said I have a very important gripe with the phone we were software
engineer still haven't found a way to solve how content will play on the
knotch with navigation gestures on so what
happens is when we decide to use navigation gestures a bar remains like a
sticky at the bottom and you cannot hide the knotch
how annoying is that therefore despite the presence of navigation gestures I
had to use the navigation keys instead please fix this own vevo also one
software feature that is different compared to the v9 is the always-on
display settings you can change the style of the clock to analog or digital
and it'll also showcase phone call or messages notification on your screen
here's an interesting thing though the vivo x21 is one of the very few phones
that supports Android P beta developer edition it's actually a part of Google's
partner program now I haven't tested this out on the vivo x21 yet we will do
that soon and let you know in a later video sometime the x31 comes with two
cameras on the rear one is a 12 megapixel primary sensor and the other
is a 5mp depth-sensing sensor also the new two Alamelu pixel sensor has a pixel
size of 1.4 4 microns this means that you can expect good details from the X
21 and you know what to some extent it actually delivers I managed to shoot
some good-looking shots and ideal lighting conditions you will see
extremely punchy colors that look good on any display
obviously the color accuracy is not ideal but a lot of folks will like this
look the problem with the camera is actually the focusing speed which is
weird because we mo actually claims faster focusing speeds but I had to stay
stable to get a shot without a blur most of the times that I thought I really
liked the new 12 megapixel camera on the rear because it takes good HD or short
suspend the portrait mode on the X 21 lets you adjust the focal length before
shooting and after shooting - according to me the sweet spot for getting a good
shot is F by 4 which is the default setting anyway the low-light shots are
not bad either but definitely not the best in class the software algorithm
works overtime to reduce the noise and as a result ends up smudging a lot of
the details but this is the case with a lot of mid-range phones and therefore
one not complain the camera can also capture
4k video but my test sample had a weird pink tint and since there is no II is
for fucking videos that was pretty shaky - on the contrary the quality of the
1080p video was pretty good with good details across the board you also get a
is out of the box for 1080p footage and that's definitely an advantage this get
interesting when you move to the front camera the front-facing camera also uses
the same 12 megapixel sensor as a real camera while it does take good selfies
the problem is that even without beauty mode on it makes my face look fairer
than usual a lot of folks might like this but I am NOT a fan oh and before I
forget you get AI based occurs on the phone which can be used to make some fun
selfies I lightly stickers they look as good as snapchat stickers the x20 one's
internal kit comprises of a solid combination of hardware which includes a
qualcomm snapdragon 616 so see 6 gigs of RAM and 128 GB of internal storage which
is further expandable up to 256 GB using a micro SD card while the 660 is a super
mid-range chip it is very powerful as we've learned from the nokia 7 plus
which we reviewed some time before in fact apart from the 616 the rest of the
specs are flagship grade in my time with the phone I didn't face a single
slowdown and the X 21 is an extremely responsive phone one weighed it as a
force performance prowess is to scroll through Facebook feed in the official
app no I'm not kidding the AM is so poorly coded that low-end chips actually
struggle to keep with the scrolling speed the experiment has no problems
whatsoever and as far as gaming is cleanser and I played guns of boom
shadows and legends and pop G all of which are graphically intensive games
all the games ran smoothly without any frame drops while family chooses the
medium graphics setting by default I push it too high and still then face any
problem the phone doesn't heat up while gaming either moving on to the audio
quality the x21 includes the high five - I really don't
know what model of hi-fi back but in my testing I found out that it could power
my one more triple driver with ease in fact the sound is pretty clean
without any artifacts as such however the single downward firing mono speaker
doesn't get very loud and the sound gets muffled easily when it is covered by a
pump as far as the coil quality is concerned I'm extremely impressed by the
ex 21 I got a stable until network with crystal clear calls even in high
congestion areas furthermore I didn't face any call drops either also the
phone app lets you record calls which could come in handy for a lot of folks
for those wondering the ex 21 has support for dual voltage a smell
powering all this is a 3200 mAh battery with support for fast charging we will
cause a dual engine quick charge and is it fast I can't believe that it is as
fast as 1 + s - charge additionally I got an average screen on time of around
5 hours and 20 minutes which is not bad but not great either basically you can
expect a day's worth of usage from the phone and charge it within an hour and a
half well miss the opportunity is that despite having a glass body the view
experiment doesn't come with wireless charging so for my final warning I am in
a different shirt that's primarily because I was actually at the event and
I'm coming to write for the event to show the verdict for you guys so should
you buy the we go X 21 well if you ask me the vo X 21 is definitely only made
for early adopters one who are really really keen on the in display
fingerprint scanner in fact when I asked my friends and
family about the in display fingerprint scanner they were mostly indifferent
primarily because they don't understand the technology but I have to tell you
this the fingerprint sensor inside the vivo X 21 is a very very big advancement
in the field of mobile technology but it's the vivo X 21 worth rupees 35 990 I
don't know I mean I cannot recommend this phone over the 1 plus 6 which is
currently the Best Buy in this price range that said the X 21 is a great
first attempt at showcasing a technology that no other brand has managed yet
kudos vivo so I hope you guys liked our review of the vivo X 21 if you did don't

awesome tech content until next time this is ershad signing off Tata
