well be the most bang-for-your-buck budget cellphone released so far in 2019. And today

we're going to see it all from the inside and maybe see if a clear version is possible

since we haven't made one of those in a while.

Let's get started.

[Intro]

The back panel of this Redmi K20 Pro is made from glass, and it's the typical glued shut

glass sandwich design we've been seeing in smartphones for years. With a bit of heat

and a sharp pry tool to slice the adhesive between the glass panel and metal frame, it

should come off easy enough. We'll be digging around inside of the phone to check out the

water resistance as we take it apart.

Once all the adhesive is cut, I can twist the panels off of each other revealing the

internals of the phone. The mechanical pop-up camera is still hidden underneath the top

plastics which we can get to in a second. Interestingly enough though, there are red

rubber fillers inside each of the button cavities. This might be the first sign of water resistance.

These red rubber strips tucked inside each of the button holes aren't used to push the

button back out like we've seen in some of the old Nintendo controllers. The rubber's

just there to take up space. And the more the holes are plugged up, the harder it is

for water to get inside. So far so good.

Getting deeper into the K20 Pro we find 20 screws which are surprisingly green. Maybe

the strange playful screw coloring is to help offset the evil vibe of the back panel. In

some electrical applications a green screw means a grounding screw, which might be the

case here....but could also just be the favorite color of the guy who designed it.

Once the screws are out I can lift off the top black plastic panel. The K20 Pro has a

square NFC pad on the back. It's a smaller signal coil and not the larger power sharing

wireless charging coil. But the technologies are still pretty similar.

The bottom plastics can come loose. These include the loudspeaker and check this out...the

speaker has the same water resistant mesh we've seen on ingress protected phones. I'm

beginning to think that Redmi added the water protection but didn't pay for the certification.

Kind of like OnePlus did a while back.

I'll mosey my way up to the top of the phone. Here we can see the internal stepper motor

system that raises and lowers the front camera. Redmi said this thing is good for 300,000

motions, just like the OnePlus and Vivo phones. It's still fascinating to see them in motion

though. The internal motor spins that threaded shaft, and as the threaded shaft spins, the

camera motors on up out of the phone. And then motors back down into the phone when

the threads rotate the opposite direction. The motor can overheat with too much use though.

Hence this warning about using the camera too frequently.

Where was I? Oh yeah. The difference between this pop up camera and other pop-up cameras

though is the LED sidebars that light up as the camera protrudes and again as it retracts.

These kinds of flashy LED RGB's are things we normally only see inside of gaming phones

or PC's.

We're going to for sure find out what these LED's look like. But first let's see what

the phone would look like clear. I'm a huge fan of psychedelic phones so honestly I would

probably just leave this one's coating intact, but it's still cool to see how the layer of

color works. It's kind of like a giant sticker that's just applied permanently to the bottom

side of the glass. Personally I think they should be sticking holographic designs under

here like the Pokemon cards used to have.

The K20 Pro sticker peels off cleanly from the underside of the glass leaving no residue

behind. I'm being very careful not to flex the glass as I peel it off though, because

glass is glass and glass can break. Some of the internal black plastics are important.

You can see the silver metallic antenna lines so I'll keep those and the connectors for

the NFC pad. And I'll also keep the lower loud speaker with it's contact pads. Once

those are cut, the clear glass can be stuck back into place, and I think it looks pretty

cool half and half like this, showing the different layers inside of the K20 Pro. The

pop up motor is visible which is the most important part. And you know, obviously, the

warranty and water resistance is now gone, so I wouldn't recommend attempting this unless

you have nothing to lose.

If you're looking for a non-permanent phone modification, it's probably safer to stick

with something like dbrand. You can get something a bit more angelic and classy like the marble

or white carbon. Or my personal favorite – the stealthy swarm or black camo. And if you know

you like playing with wood, you can always get real crazy with bamboo or something. And

since the skins are protective, yet non-permanent, they don't void any warranty. I'll put a link

down in the description for you. And thanks to dbrand for sponsoring this video. Let's

go deeper.

I'll unplug the battery connector like a little Lego, and then I can unplug each end of this

long extension ribbon and then we can remove the battery. This is one of my favorite styles

of battery adhesive: the strong tangible pull tabs. The adhesive is thinner than the magical

pull tabs we see inside iPhones or even the permanent adhesive we see inside the Samsung

phone. And look how strong it is. Before I release tabs one and two, the battery was

attached to the phone stronger than I can physically remove. But once tabs one and two

are released, the whole battery comes out easily and cleanly with no bending or dangerous

prying. Plus no broken pull tabs. Huge thumbs up for that. The battery is a 4,000 milliamp

hour capacity.

I can unplug the bottom motherboard ribbon and the lowest camera, the 13 megapixel wide-angle.

Pulling this guy out to get a closer look reveals that there is no optical image stabilization.

We can pop out the other two rear facing cameras out of the housing to get a closer look at

them. The top 8 megapixel telephoto camera and the middle normal perspective 48 megapixel

Sony sensor, neither of which have the physical image stabilizing that we've come to expect

on high-end phones. But this budget phone is extremely feature rich at like $350, so

we can't complain too much.

I'll remove the one massive stand off screw holding down the motherboard and motor. Then

I can unclip the super long front facing camera extension ribbon with my plastic pry tool.

And that releases the motherboard. The motherboard has a built-in headphone jack and a pretty

solid glob of thermal paste on the back for the thermal cooling. The motherboard sits

on top of this copper foil. It's not pure copper like we've seen in some of the major

flagships, but still enough that it's sufficient. It kind of has a rubberish feel and look when

I pulled it out, so I grab my lighter and since rubber will start to burn and melt before

copper will, I started it on fire. The copper foil did not melt, but very efficiently transferred

the heat from my flame right into my fingers holding the other side of the foil. So we

definitely know it works.

Let's take a closer look at the light up pop up camera and see where that red frontal glow

comes from. Surprisingly there is only one more screw left holding it in place - another

green little guy. I'll remove that and then lift off the motor power ribbon and pull the

stepper motor out. Then I can slide the pop up camera up and out of the phone.

Since there are no LEDs shining up into the lower portion of the housing, it means everything

must be self-contained inside the boxy camera. So in order to find it, we have to remove

the camera covering – the red plastic with the translucent bars along the side. My razor

blade can slice through the housing and leverage off the top revealing some pretty cool internals.

The LEDs are actually located around the base of the camera and they shine up into the cloudy

clear plastic rainbow. The light rays reflect off of the intentional cloudiness of that

plastic allowing the entire sides and top to glow. We've seen the same effect achieved

in the ROG gaming phone. And, you know, not to toot my own horn, but I also included this

in the LED wall mounted PC that I built 5 years ago. I'll put a link for that incredibly

old video in the description.

Fun side note: this pop up camera has the same rubber ring around the base to help keep

water and dust out that we saw inside the OnePlus phone. Just another indicator that

Redmi has put effort into water resistance. I'll get the motor situated back into it's

grooves in the metal frame. Then let's see what the K20 Pro has down here at the bottom.

Right off the bat we see the old school rotating mass vibrator motor. I can unclip all the

attached ribbon cables and there are no screws holding the bottom board in place. But for

some reason it's still won't come out of the phone.

On a completely unrelated note, the dual SIM card tray is down here. It also has a very

thin rubber ring around the base to keep water and dust out. And now magically the charging

port board is ready to come loose, showing us it's 27 watt quick charge capable USB-C

port with a white hexagon shaped water damage indicator. There is rubber around the tip

of the port. And if we look closely we can see another tiny water resistant screen inside

the phone over the microphone hole. It's hard to call this phone totally water resistant

since it has so many large openings. But it does have a lot of protections against water

and that's always a good thing.

The under display fingerprint scanner is right here under the display. Redmi's calling this

a 7th generation optical scanner and I don't have any complaints with it. Personally, I

think underscreen fingerprint scanners are pretty cool. Overall I'm pretty excited about

the K20 Pro. It just proves that a lot of the latest and greatest flagship features

are now popping up on budget devices. Cheap phones are catching up and catching up quick.

There's really no reason to spend $1000 on a smartphone...unless of course you use it

for business and the phone is paying for itself.

With all the cameras clipped back into place and the ribbon cables connected, I'm ready

to add the battery and the long extension ribbon with it's upward facing arrow. Then

I can get the back plastics screwed in with all my green screws. This phone is all kinds

of fun.

I'll put the clear glass into place on top of the phone, and lucky for us the whole thing

still turns on. The power button has a very interesting connection with the gold contact

pads resting up against the bottom side of the motherboard so if the motherboard's not

screwed down, it doesn't start. If your phone ever does get wet and stops working, cleaning

off those contact pads would be a good place to start. It's a weird connector.
