Galaxy Z Fold 2 Teardown! Where is the ‘Folding Glass? Today we’re going to take apart the new Samsung Galaxy z fold to one of the most over-engineered smartphones of all time. I’m not wrong, though. That means there’s more for us to look at inside. We’ll start by turning it off and then turning it right back on again because we’re crying alive today. Let’s get started.
Any responsible phone repair technician or manufacturer would advise against what we are about to do. But if we want to learn more about the limits of Samsung’s flexible screen technology, try to know at what point the screen will, you know, pass on from this mortal existence. We’ll start by removing the plastic border around the interior display, try a buffer to keep out dust, as well as keep the phone has from clicking together when it’s folded shut. It’s got a copper wire inside to help with the structure, as well as little clips and glue, holding it to the phone frame, try only stronger than last year’s afterthought of the border. There is a little buffer of foam at the center crease that slips in the crack between the two halves. This might be what helped keep the dust out during the durability test. I hear the bristles inside the hinge. So we’ll have to find those once we’re done with the screen. The screen is still alive at this point. So far, so good; if it’s anything like last year’s fold one, we know that there is a bunch of adhesive underneath. So we’ll warm that up with the heat gun, a razor blade to lift on the metal plates supporting each app. You’ll notice that if my razor is underneath that metal plate, nothing happens. But if my razor accidentally goes through the. Layers into the screen, the pixels instantly die. So we’ll avoid stabbing the pixels, and everything stays pretty much intact until we start lifting around the screen that’s unglued.
The center spine of the Z fold has started to freak out a bit. This does not indicate a potential flaw or overly fragile device; removing that plastic edge like removing an arm or leg. It’s a very vital piece of the screen, and I’m already impressed with how long it’s lasted without it. You can see the front-facing camera peeking up through the display as it gets lifted up and down, Kind of fun—thumbs up for that. A warm-up the other half of the display, and they use my same razor blade trick underneath the metal plate to pry it off and work well. It’s a flexible folding display, so we should bend it up as long as we don’t touch the edge too much, you know, since we removed that protection. And, well, we touch the edge, see where my thumb is without that edge protection, the whole line of pixels is now toasted, because I squeezed the edge of the screen, with a few more carefully place slices we can remove adhesive holding the screen to the body. And all we’re left with is the ribbon cable that connects the display to the internal motherboard try. As a side note, about one in 4000 people suffer from the photo.
It kills the pixels too tight of a fold also should break the ultra-thin glass layer underneath the top plastic.
And indeed, that’s exactly what we’re seeing. The screen is super excited about this new development. But if we look closely, we can see super tiny cracks all along the tight fold I made in the folding display. These hairline fractures are definitely underneath the top soft plastic layer, try to get to them; I can slide my razor blade very carefully between the transparent top plastic layer and the pixels so that we can get a better look at that thin glass underneath; got to admit it looks pretty cool, the pixels die like a runaway ink stain The top camera is still working. By the way, it’s just the screen that’s having a moment; the folding glass is very much more visible at this point since it’s all shattered and busted a bit.
It is ultra-thin, Kind of calm as much as that was though I think it’s time we turn off the phone and open it up like an average person. So we can get a better look at the internal hinge and those new bristles. First things first, the teardown skins got to come off. Link in the description ., then we can use the old heat gun razor plate combo to remove the screen. Just for the record, repair shops usually have large hot plates, and suction machines do this a bit safer and more efficiently. So if your phone ever does break, don’t think every repair guy is running around with a hairdryer file; there are simple tools for this Kind of thing. Once the adhesive is cut around the outside, I’ll turn it on quickly to break anything since, you know, the rest of the phone is in such pristine condition. Looks great. Once it’s off again, I can pop out the rubber stopper. Green Ribbon. Remove the screen and head over to the only place on this phone without a screen a little more heat and slicing back glass. It comes away in one piece. It’s got a small little microphone on the back camera lens. This is either for better video or just for the noise canceling. With the exteriors removed, we can now see the 24 visible Phillips head screws and the additional two screws hidden underneath the wireless charger. With the screws all gone, we can get the wireless and reverse wireless charger removed; they can do the little circle pads that rest on top of the motherboard. And we can unplug the battery. If you notice up here, my z four to five G is missing the internal 5g millimeter wave as well, because not every version of the z 425 g will ship with those installed; Samsung is a pro though at giving different versions of their phones in different markets without disclaimers, so nothing super new here, try the other half as a cavity for the top loudspeaker. You can see the earpiece is also built-in at the same plastic piece; even though the phone is water-resistant, we still see the waterproofing mesh over the top of the speaker opening, and the foam balls are still inside underneath the red sticker. The bottom piece of plastic has the other stereos and is also full of sound dampening balls we see in higher ed speakers. I’ll disconnect the right battery. And let’s take a look at the internal folding screen. We can see it pops up through the frame right here above the battery, and then just like a little Lego with the large screen removed, we get our first look at the silver metal structural side supports and the copper layer, which I imagine helps keep the whole screen cool. The coolest thing besides that, though, is this portion. Since a solid piece of metal would be too stiff to bend, Samsung has used little sticks of aluminum, like a fence or one of those rolls up bamboo yoga mats. This gives the flexible screen support and only lets its direction; these little details on the inside are pretty cool.
We still haven’t found the internal bristles yet. Let’s disconnect the side button ribbons and the broader extension ribbons that connect the circuit boards.
.. After removing one more screw at the bottom, the charging port board can come away from the phone. The USBC port can fast-charge at 25 watts and has its own water damage indicator sticker on the back. This will turn pink if the phone ever gets wet, is equal to has no IP rating.
Now we can remove the right motherboard. With its top inside front-facing camera tripod, the green one is identical, which is identical in size and shape to the 10-megapixel camera out the exterior front screen. It’s interesting that Lego-style connectors are also both blue and green but don’t match up with the blue and green boards they’re plugged into. They are probably interchangeable, though. Two more screws are holding the mainboard. And once that’s lifted off, we see the graphite cooling bed. We’ll talk about that more in a second. All of the rear cameras on the Z fold two are 12 megapixels, the ultra-wide camera up top, the regular camera with though is in the center, and the 12 Megatron telephoto camera down the bottom, which also has the optical image stabilization. Now for the graphite pad, Samsung doesn’t talk about this much, or at all.
During my cooling system swap between the Exynos and the Qualcomm processors, we found that the type of cooling doesn’t have much of a difference in the heat transfer. The copper vapor chamber behaves pretty similarly to these layers of paper-thin graphite, so it’s not ideal. Interestingly enough, though, reports are that every single one of the default twos will be equipped with the more powerful Qualcomm processors instead of the Exynos chips. So, that performance dip isn’t something you’ll need to worry about with this $2,000 phone. It’s just the 1300 dollar phones you got to watch out for. The SIM card tray has it done cute little board; an SD card would have been cool to what it is. The part that I hate most about Samsung phones is the batteries; while every other phone manufacturer uses regular adhesive or magic pull tabs, Samson likes to show off the world’s strongest glue. Oh, one piece of this stuff would have kept the Titanic from sinking. I want to ask, Where is this battery going to go, Samsung. If you were strapping it to a Mars rover, this amount of glue would make sense, but the phone’s already sealed. And the most velocity it’s ever going to encounter is falling on someone’s face after an hour of sleep scrolling; the glue is overkilled. I’ll let some isopropanol alcohol underneath the battery to dissolve the adhesive now that it’s exposed. But still, I should invoke a chemical reaction to remove my battery. The larger battery is 345 milliamp hours, and the smaller battery is 2155 milliamp hours. I’m just going to leave that one in the frame. Finally, the hinge. Some hinges are simple tricep duo or the Motorola razor. But Samsung likes to show off some engineering prowess, and I’m not complaining.
Five straps are holding on to the Centerplate, which, once removed, exposes the underside of the two flexible ribbons running through each half. These ribbons only have to flex 190 degrees, so they are just the regular ribbon. Though the Microsoft duo also had two ribbons connecting the hands, its ribbons are made from the stringy metal that flex is 360 degrees. It’s interesting to see the ways different companies can solve the same issue. I’ll remove three more screws from the bottom and another three at the top. And once those extension ribbons are unstuck from the frame. We get our first look at the hinge cavity and the long line of bristles that sit just inside. It’s a super fine line of short little brushes that allow enough space for the hinge to flex while still keeping a pretty decent seal, as we saw from the durability test video. It’s impressive that such a small and probably inexpensive addition can solve such a massive problem. The rest of the hinge is relatively stable last year. It still has this long metal spine, whose color is customizable this time around, and still has many super tiny gears and internal coils that regulate the force required to open and close the hats. I’m impressed. Between this and the LG wing and the Microsoft duo, 2020 has been a pretty good year for uniquely built aisles. Yeah, my z fold two might not be alive anymore, but at least we got to see how it works from the inside. Try rest in peace, a much less expensive and less catastrophic way to see the inside of your phone, of course, would be to grab one of my teardown skins from D brand. It’s a fraction of the cost with all of the pleasure. We have skins for over 50 different devices. Now try the link down in the description. What’s your favorite phone that we’ve taken apart this year.
