Xiaomi Mix 4 Hands-On: Snapdragon 888+, Under-Screen Selfie Cam!

The Xiaomi Mi Mix 4 is here! I got my hands on the device and took it out for a night around the Tai Wai district of Hong Kong.

xiaomi
00:04
mix 4. this thing literally
00:07
just arrived like two minutes ago so
00:10
what i’m gonna do is i’m gonna unbox
00:11
this phone
00:12
set it up and i’m gonna take it out for
00:15
an evening out and about and i’m gonna
00:16
come back it’s gonna be like midnight
00:18
and i’m gonna edit the video work till
00:20
4am to get this video out xiaomi mix for
00:24
a day in the life so the mix 4 is only
00:26
sold in china right now so this is a
00:29
china unit the box right here it says
00:32
slice and we are you made
00:34
so basically there’s no
00:36
perfection in the world but then there
00:38
are people who chase perfection
00:41
okay so we have the phone here let me
00:43
put it to the side first so i wanted to
00:45
say i was actually um very fortunate
00:47
when xiaomi first announced the original
00:49
me mix i was one of the very few english
00:52
reviewers to get my hands on the phone
00:55
and i remember just being completely
00:56
blown away by the original remix and the
00:59
me mix
01:00
4 may do just that too because it has
01:03
the first commercially released
01:05
underscreen camera i mean samsung has
01:07
one coming but the 4-3 is not on sale
01:09
yet so this is the first one to
01:10
officially go on sale so we have a
01:14
jelly case inside clear plastic jelly
01:18
case
01:18
i’m not going to use it my theory is
01:20
when i get a phone this beautiful i want
01:23
to be able to look at it and feel it in
01:25
its natural form now granted i am
01:27
spoiled as hell i know a lot of people
01:29
out there who buy phones will use the
01:30
case
01:31
so we have a
01:33
120 watt wired charging brick so this is
01:37
the china us plug here’s a usbc
01:41
cable
01:42
and what is this this is probably a
01:44
dongle yeah a headphone jack 3.5
01:46
millimeter to usbc dongle
01:55
oh
01:56
this thing feels nice
01:58
ceramic back
02:00
it’s hefty but not necessarily in a bad
02:02
way it feels very dense in that premium
02:05
way
02:07
okay we are in
02:09
so the first thing we’re gonna do is
02:11
we’re gonna test out this under screen
02:13
selfie camera
02:16
okay definitely looks slightly blurry
02:18
right now in the viewfinder
02:20
but xiaomi software should do some ai
02:23
processing to sharpen up the shot and
02:24
also this is a challenging situation
02:26
because we have a light right behind me
02:28
i believe this is one of the weaknesses
02:29
of an underscreen camera because there’s
02:31
pixels covering the camera so
02:34
basically when you have direct light
02:35
source in the back it’s not going to
02:36
look as good as a better lighting
02:38
condition
02:44
okay yep you can see in real time
02:47
xiaomi software did some post image
02:49
processing to produce a shot that’s
02:51
sharper so you can see the camera
02:54
pretty nicely the light behind me kind
02:57
of disappeared like you know in the
02:58
viewfinder you see how there’s a little
03:00
bit of light that’s overexposed but then
03:01
you look at the photo it’s disappeared
03:04
my face is reasonably sharp i mean i
03:06
don’t want my face to be that sharp
03:08
anyway i don’t have good
03:10
skin but this is um
03:12
poor lighting conditioner let’s go
03:14
outside for a
03:15
better
03:16
selfie
03:19
okay so we have a pretty sunny day right
03:22
now outside let’s test out the selfie
03:24
cam out here so once again on the
03:25
viewfinder i can see
03:27
the light
03:28
behind me looks completely blown out on
03:30
the viewfinder but software will
03:31
probably fix this
03:34
yeah so the selfie looks pretty good
03:35
looks pretty sharp obviously it doesn’t
03:37
look as good as a normal selfie camera
03:39
without a display layer over it but this
03:42
is definitely better than the z-fold
03:45
force on the screen camera but you know
03:47
this is just a brief test i’m gonna take
03:48
this phone out and about to test not
03:50
just the selfie camera but all the other
03:52
bits a little bit more too let’s step
03:54
inside i’m gonna see if i can put google
03:56
on this phone okay so like i said this
03:58
phone is a china model so it does not
03:59
come with google apps out of the box but
04:02
you should be able to install google
04:03
apps relatively easily just jump into
04:05
xiaomi’s own
04:06
app store
04:07
and then search for google
04:10
and you have gmail let’s install gmail
04:12
you just have to install one major
04:14
google app and then it should set up the
04:16
rest of the stuff so it’s already
04:18
downloaded open
04:20
i already have two step authentication
04:22
so i just need to tap yes on my other
04:24
phone
04:25
now we’re in we’re inside gmail let me
04:27
see if google play store is installed no
04:29
it is not so i just have to
04:35
okay while we have a white screen open
04:37
let’s look at the on the screen camera
04:38
so don’t mind this flickering here
04:40
that’s just my camera shutter speed in
04:41
real life i cannot see the flickering
04:43
but you see you actually don’t see
04:45
anything
04:46
underneath the selfie camera you know
04:48
how the z-fold 4 when you have a white
04:50
screen open you actually see a little
04:51
bit of flicker like because the pixels
04:54
over the screen is flickering you don’t
04:55
see that here it’s a lot more discreet
04:58
at least so far okay while xiaomi
05:00
software is smart enough to clean up the
05:02
haziness
05:03
of selfie photos it appears i cannot do
05:06
the same for selfie videos
05:08
because i look pretty hazy right now
05:09
there’s main camera footage and i’m
05:11
gonna switch to the selfie camera
05:13
and now this is the selfie camera
05:18
okay let’s keep track of battery so
05:19
right now is 6 28 p.m and the battery is
05:23
at
05:24
60
05:25
exactly 60.
05:28
okay so right now i have the hong kong
05:30
skyline behind me with major backlights
05:32
we’ll test the selfie camera
05:36
yeah the photo quality definitely leaves
05:38
a lot to be desired
05:45
but you know that’s shooting in really
05:47
challenging conditions now if i am not
05:49
against that play it should appear a
05:50
little bit better
05:52
yeah much better when i’m not against
05:54
direct backlight
06:22
okay so now i am in the thai white
06:24
district of hong kong you’re watching 4k
06:26
30 footage of the me mix 4 as you can
06:29
see it’s getting a little bit dark
06:30
perfect time to test low light photos
06:32
and videos so we have the nemix4 footage
06:35
on the left and the s21 ultra footage on
06:38
the right just so you guys can
06:40
compare video quality
06:43
just
06:44
from what i’m looking right now the s21
06:46
ultra photo seems a little bit brighter
07:00
so reason i like coming out to this area
07:02
is because one it’s a little bit less
07:04
busy than
07:06
center hong kong like you might be
07:07
seeing this many people and think
07:09
i think it’s really crazy for me to say
07:10
it’s less busy but i will get to an area
07:13
where it’s a little bit more quiet and
07:15
also there’s a lot of good street food
07:17
it’s a lot of good hole in the walls to
07:19
eat there’s ultra wide-angle camera
07:22
footage
07:24
oh wow that’s a beautiful sunset
07:27
let’s take a couple photos of the mix
07:29
four
07:33
five times zoom
07:39
okay i’ve sat down at a coffee shop so
07:41
let’s go over the overall hardware of
07:42
the meme force so we have a 6.7 inch
07:44
hole display 120 hertz refresh rate now
07:48
resolution of this is 1080 by 2400 so
07:51
it’s a little bit
07:52
not as pixel dense not as high res as
07:55
the mi 11 ultra screen in fact look at
07:57
the overall spec sheet it appears that
07:59
the mix force components
08:01
are like a hair
08:03
a slight notch below the mi 11 ultra if
08:06
you look at the camera module of the m11
08:08
ultra next to the mix 4 you should
08:10
already be able to see that the
08:11
periscope zoom lens and the ultra wide
08:13
lens on the mix 4 is much smaller than
08:16
on the m11 ultra and the specs reflect
08:19
that but even if the camera hardware is
08:20
a little bit behind what the mi 11 ultra
08:22
offers it’s still a pretty
08:24
powerful module so the main camera it’s
08:26
a 108 megapixel iso cell hmx sensor
08:30
image sensor size one over 1.33 inch so
08:33
they’re still pretty large but
08:35
definitely not as large as the v11 ultra
08:37
sensor and then you have a 13 megapixel
08:40
ultra wide angle camera it’s a freeform
08:42
lens meaning that it minimizes
08:44
distortion and down here it’s an eight
08:46
megapixel periscope camera with five
08:49
times optical zoom the battery inside
08:51
the mix 4 is a 4 500 million hour cell
08:55
which is uh not that big so i’m slightly
08:57
concerned
08:58
about battery life in fact let’s check
09:01
right now so we we started tracking at 6
09:04
28 with 60 battery life so right now it
09:07
is um
09:08
744
09:10
and it has 45 battery life i don’t know
09:12
the camera will focus just take my word
09:14
for it so another reason i like coming
09:16
out to these uh outer areas of hong kong
09:19
is that you get to see these older
09:21
village houses that you can’t see where
09:23
i live in the city center so if you look
09:27
back there let me see if i’m focused
09:29
that’s a village entrance now i’m not
09:31
going to get too close to them because
09:34
they might yell at me so that’s why a
09:36
zoom line comes in handy because now i’m
09:37
gonna get some photos of the entrance
09:39
without moving any closer i have the mix
09:42
four here let’s go
09:44
five times zoom
09:46
yeah this periscope zoom lens definitely
09:48
struggles with focus a little bit it’s
09:50
still not
09:51
okay five times zoom
09:56
we’ll go deeper ten
09:58
now i can read the text
10:07
[Music]
10:08
we’ll take a selfie
10:10
so once again this is low light it looks
10:12
very blurry right now i think
10:15
in post yup impulse xiaomi does
10:18
fix it up so it looks
10:20
decent
10:21
okay so let’s look at the software
10:23
really quick so this phone runs me ui
10:25
12.5.2
10:27
this is the china software so out of the
10:30
box there’s no google and when you swipe
10:32
to size there are these chinese widgets
10:34
and quite a lot of chinese apps but you
10:36
can
10:37
delete most of them and you see once
10:39
again you look closer at the screen at
10:41
the top of the screen you don’t really
10:43
see that selfie camera underneath
10:45
there’s no flickering not like on the
10:48
samsung galaxy z43 where the flickering
10:51
is pretty noticeable okay you guys know
10:54
what’s up time for a video speaker test
10:56
so this phone has stereo speakers tuned
10:58
by harman kardon
11:00
this is 50
11:05
100
11:08
[Music]
11:12
okay i’m gonna take some more photos and
11:13
videos and i’m going to head back
11:15
to examine the photos for the mix 4
11:18
on the larger monitor but i think right
11:20
now just look at the small screen i can
11:22
already kind of see that the mix 4
11:24
selfie camera is obviously
11:27
you know it’s technically impressive
11:28
it’s under the screen but if you just
11:30
talk about quality pixel peeping it’s
11:33
not going to be better than the selfie
11:34
cameras of the iphone 12 or the s21
11:36
ultra or the mi 11 ultra or any xiaomi
11:39
phone but i think that’s okay because
11:41
the xiaomi mi mix phones have always
11:42
been about
11:43
exploring about pushing boundaries and
11:46
it’s like a concept because i don’t know
11:48
if you remember the original xiaomi mi
11:50
mix also had a pretty weird
11:52
selfie shooting situation because the
11:54
selfie cam was actually at the bottom
11:55
chin bezel so anytime you want to take a
11:57
selfie you have to flip the phone upside
11:59
down and on xiaomi mi mix 3 it’s a
12:02
slider phone so anytime you want to take
12:03
a selfie you have to use your thumb to
12:06
pull the screen down it’s an extra step
12:08
so what i’m trying to say is
12:10
every xiaomi mi mix phone before you
12:12
know the slap phones anyway have a
12:15
compromised
12:16
selfie shooting experience it’s slightly
12:19
either more cumbersome or not as good as
12:22
just taking selfies with a me 10 or me 8
12:25
or me 6.
12:27
and and that’s kind of the idea here if
12:29
you just want a simple no hassle selfie
12:31
experience get the mi 11 ultra or the mi
12:34
11 or the mi 11 i or the mi 11 lite or a
12:37
mi 11 pro there’s so many phones but if
12:40
you want bleeding edge technology you
12:42
know be the first to see something then
12:44
the mix 4 is here for that and the
12:46
screen completely uninterrupted does
12:49
look pretty damn nice that’s for the
12:51
main camera system
12:52
i’m examining the photos a little bit
12:54
more and maybe come back if my opinions
12:55
differ but so far i think
12:58
the cameras are pretty good but the mi
13:00
11 ultra seems to be a step ahead and
13:02
probably the s21 ultra too
13:05
so
13:06
so really the mix 4 is the kind of
13:08
bleeding edge
13:10
concept cool device while the mi 11
13:12
ultra or even the standard me 11 are the
13:15
safe slab flagships that you get if you
13:18
just want best all-around performance
13:20
okay before i wrap the video up let’s
13:22
take a look at the battery situation
13:24
again so it is 8 19 right now and i’m
13:26
down to 39
13:28
battery life 8 19 39
13:31
so that means if i take the mix 4 out
13:32
and about it should last me 10 to 11
13:35
hours maybe 12 hours the good news is
13:37
there’s a charging brick in the box
13:40
it’s a really damn fast charging brake
13:41
to 120 watt and the phone supports
13:44
wireless charging up to i believe 55
13:46
watts
13:47
okay so that’s about it for this first
13:49
impression hands-on video on the xiaomi
13:51
mi mix 4. i’m definitely going to have a
13:53
lot more content on this phone i’m going
13:55
to make it my daily driver put my main
13:56
sim card in there and i’m going to use
13:58
it for a week and come back with a full
14:00
review maybe i’ll do some camera tests
14:02
too maybe there’s a lot of stuff coming
14:04
this month
