  • The new 2020 Motorola Razr is ridiculously complex. Yet also incredibly simple. I'll

  • explain. Today we're going to take apart the new flexible flip screen Razr. We've already

  • taken apart the other folding phone, the Samsung Galaxy Z Flip. So we'll be able to compare

  • the two internal hinge mechanisms side by side. One side note before we get started:

  • when I was tearing down the Samsung Galaxy Z Flip and looking for the bristles that help

  • keep out dust, I was so focused on finding the bristles inside of the hinge itself that

  • I didn't notice Samsung had positioned the bristles elsewhere across the bottom portion

  • of each half of the frame. Luckily you guys caught this pretty quick and I was able to

  • update the description and pin a comment in the tear down video so thanks for that. The

  • bristles look like strips of black tape at first. But I want you to see what they look

  • like close up. These bristles stretch all the way across the frame, and this is what

  • helped keep the dust out of the phone during my bend test, even after the phone was bent

  • backwards and had the frame snapped. I fix it to their own dust test and found that fine

  • particles still managed to get inside of the phone. But for normal size dust and sand particles,

  • I think it does a pretty good job of protecting the insides.

  • Now it's time to see if the Motorola Razr has any protections built into it's own hinge.

  • Let's get started.

  • [Intro]

  • So when I said the Motorola Razr was ridiculously complex, I was talking about the organization

  • of components inside. Everything is kind of helter-skelter until we get to the hinge.

  • But it's still super interesting. To get inside the phone I'll start by heating up the back

  • plastic cover. Then I can pry it away from the phone with my razor blade and shimmy it

  • down off the frame at the same time. The plastic housing is still attached to the phone though

  • with the fingerprint ribbon cable that's plugged into the base. There's not a good way to unplug

  • it at this point without removing these 4 T3 screws. I'll link the tool kit I use down

  • in the video description.

  • The inner plastic housing that I just pulled away is for the loudspeaker and the antennas.

  • I can unplug the speaker just like a little Lego. You can see the singular speaker itself

  • inside of the plastic frame. There is a water damage indicator down here next to the charging

  • port. You can see that it's white on one side and red on the other, so if the phone ever

  • gets wet, the red will bleed through and turn pink. Motorola has come up with some very

  • creative ways of making this phone water resistant though. All of this goop surrounding the ribbon

  • cable connection helps keep dust and liquid away from the important bits. This goo feels

  • exactly like you'd think it would.

  • Flipping the phone around I now have access to the fingerprint scanner cable, and I can

  • pop that out of its little connector. Now, the smaller glass screen that can be seen

  • when the phone is folded shut is glued on pretty tight. Much more solid than usual.

  • It's very difficult to separate the glass from the fame of the phone. Eventually, after

  • many rounds of heat and gentle slicing, I was able to separate the screen and fold it

  • away from the phone. Then I can unplug that OLED panel and release the 2.7 inch screen.

  • What makes this teardown complex is that there are actually four sides to the phone. These

  • two sides on the rear portion of the phone, and another two sides under the screen. We're

  • already pretty deep inside this thing and we still have yet to see the motherboard.

  • I'll reach in and unplug the bottom battery. There's two of these inside the phone. Each

  • half of the phone has it's own battery. Then I'll remove 4 more T3 screws and unclip the

  • folding screen ribbon and the NFC. Then the battery and motherboard sandwich can be removed.

  • This motherboard looks quite a bit different than what we're used to. I believe that's

  • because each of the little chips on the board has it's own cheese grater looking Faraday

  • cage shield thing over the top. These shields block electromagnetic fields. Most regular

  • phones, you know, the non-folding ones, are enclosed in a metal and glass sandwich. But

  • this motherboard only has a thin folding plastic screen over the top for protection and that's

  • why the cheese graters were added over the chips. Either way, I think Motorola gets a

  • thumbs up for how cool this looks.

  • The battery is a 1245 milliamp hour capacity. We'll find the top battery here in just a

  • second. Now here's where we run into some issues. Remember, my phone was accidentally

  • folded in the wrong direction which yanked the bottom of the screen out from it's normal

  • position and the whole thing is very much stuck. Now Motorola is offering screen replacements

  • for this phone for $299 which is pretty fair considering how this is a brand new futuristic

  • flexible technology. And it's already the same price as an iPhone 11 Pro screen replacement.

  • Even after aggressively trying to slide the screen down with some pliers, it still wouldn't

  • budge, so I'm sure I did this the incorrect way and just popped it out the top, then peeled

  • it up off the rest of the phone. It's still crazy how thin this is. You can physically

  • see the 4 puncture wounds in the back from my reverse bend. Phone yoga is pretty dangerous.

  • I found 8 screws holding the top portion of the phone to the frame. Once those were out

  • I could start removing the top battery. But everything is still very much connected. You

  • can see the long extension ribbon floating through the hinge mechanism, just like we

  • saw with the Samsung Z Flip. I'll unplug the side buttons and the large extension ribbon.

  • But before I can separate all the pieces. They're still held together with one more

  • T3 screw in this top little board, and a connector underneath. The phone isn't very well organized

  • inside. But what it lacks in organization, it makes up for in silly putty. There is a

  • slathering of clear goop all over these top boards. And if I had to guess, with how sticky

  • it is, it's probably going to be pretty effective at keeping dust and liquid off the board.

  • The rear facing 16 megapixel camera does not have optical image stabilization. We have

  • another water damage indicator here next to the battery, and even though I'm calling this

  • phone complex to take apart, there is probably a reason for it. Normally in cell phones,

  • all the connections are easy to access on top of the board. But on this Razr, the board

  • is screwed down and everything is attached underneath which does complicate things. But,

  • if you think about it, it probably helps keep everything plugged in tight while the phone

  • is being flipped 200,000 times over it's lifespan. So the complexity might be a good thing.

  • The battery is glued into place. It's a 1265 milliamp hour. So now we're just left with

  • the frame of the Razr and the hinge. And this design couldn't be more different than the

  • Z Flip. Let's check it out. After removing 2 screws we can see that the center of the

  • phone has two flappy bits. These support each half of the screen as it folds shut. Remember,

  • the Razr has a much more gentle curve inside with no crease in the center of the screen.

  • I'll remove two more screws holding down the silver chunk in the center. This heavy guy

  • is the culprit of our 4 damage marks in the center of the screen during the bend test.

  • If you remember, the 4 corners of this guy must have been what pressed outward into the

  • screen from behind. Hopefully that doesn't start to happen with normal use. The curved

  • back side of this metal chunk helps keep the extension ribbon from kinking inside the hinge

  • while it's folding.

  • I'll remove 2 more screws on either side of the hinge. These hold the exterior pins in

  • place. This is where we start to see how much more simple Motorola's design is over Samsung's.

  • This is going to blow your mind. If we zoom in close we can see that these side portions

  • on the Razr aren't just for decoration. They are the hinge. Like literally kind of the

  • whole thing. You can see that each half of the phone has little gear teeth to keep each

  • half folding equally. But these two little bars on either side of the phone is what keeps

  • the phone halves together and allows the hinge to bend. You can see that the left side has

  • the same dual pin design, and once both of them are popped out and removed, the whole

  • phone can just fall apart. Now all we have left are two metal flaps and the ribbon cable

  • that's stuck inside them and that's it. Really simple.

  • I can hold both halves of the phone together so we can see how the stationary gears line

  • up. There aren't any other moving parts inside of the spine of this phone. It becomes more

  • mind blowing when we hold Samsung's hinge up side by side to Motorola's hinge. Samsung

  • is over here doing rocket science and Motorola just pops a pin in there like a door and is

  • ready to rock. Door hinges have been around for thousands of years and Motorola's just

  • going to keep on using them.

  • You might be asking yourself, 'Hey Jerry, how does the phone spring open and shut though?'

  • And I'm glad you asked. It would be real embarrassing if I miss something important like that. Motorola

  • has very smartly concealed their spring loaded mechanism inside the phone frame, away from

  • rocks and dust. When the phone guts are in place, the springs are protected inside the

  • frame side walls and can be pressed up against the hinge pin to hold the phone open or closed

  • and provide resistance during the opening and closing process. Pretty solid design.

  • Overall I'm impressed with both phones. Both present new and unique ways of utilizing flexible

  • screen technology. And I'm excited to see where we go from here. I'm pretty happy with

  • my personal Note 10 Plus for now, but there's a good chance that my next phone might just

  • be a folding phone. The price is dropping quite a lot with each new version. And I'm

  • sure, eventually, they'll be as durable as the phones we have now.

  • Now that you've seen how both phones work from the inside, which one is your favorite?

  • Let me know down in the comments. Hit that subscribe button if you haven't already. I've

  • got some pretty cool videos coming up. And come hang out with me on Instagram and Twitter.

  • Thanks a ton for watching. I'll see you around.
