Unfolding the first trifold phone

(instrumental music) – Folding phones are boring. Look we've had the first
wave of foldable devices and they're neat, but you've
seen all that already. This is about what comes next after the current generation of foldables. Sling like the tri-fold from TCL, a wild new concept, folding
tablet, phone thing. (techno-music) Unlike most foldables the
tri-fold has two hinges, which lets it fold up into thirds . You can use it as a phone, you can unfold it once
to use as a bigger screen or fold the unfolded
into a full size tablet. It's not a half way compromise
like some of the other foldables that we've seen which basically turn into just slightly
wider phone displays.

This is a full blown tablet. It's nearly as big as an iPad, but you can still fit it in your pocket. The screen folds from a 10 inch tablet down to 6.65 inch phone. You could also open it two-thirds the way and ya know prop that up it'll auto rotate so you can use in whatever
orientation you want. There's a lot of weird use cases that you could probably use this for. The screen on this one is a 3k panel, but again that's just this prototype.

We have no idea if the finished
version will have that, but the tri-fold shows just
how hard it's gonna be to turn these ideas into reality. I've gotten to play around
with the prototype for a bit and it's really rough to use right now. It is incredibly heavy for a phone. It's got those big metal hinges
and there are three separate batteries to power all those displays, it's basically three phones.

And even though it's really
thin as a tablet the phone mode is super thick and that's
before your worrying about things like the software, which is basically non-existent. Durability which is a huge question or price which who even knows. (techno music) But looking even further into the future. TCL also had a very early
mock up of a rollable phone. This is really cool idea
that's a phone that has a fully flexible display that
slides around the side and behind the phone. And it could roll back out
and become a larger display when you need more space. The way it will, in theory, work is that there's gonna be motors
on the inside of the phone and you'll press a button
and it'll expand out from a 6.75 inch display
to a 7.8 inch screen.

Now that doesn't sound like a
lot, but your actually getting almost double the screen space
it's almost twice as wide. The whole system is actually
pretty similar to the rollable Oled TV that LG's been
showing off for years. Now again this is a really early concept, it's not even a functional
device, just plastic and a screen that's literally
just a sheet of paper.

Is this a good idea? Who knows. It does avoid some of the
issues of current foldables, like those easily breakable hinges and the creased display which is cool. But it's almost guaranteed
to have issues of its own. Moving parts they're tricky. Now the tri-fold is
just a proof of concept and the plastic sliding one even more so. You won't actually be able to
buy either of these devices and it's not clear if TCL's
actually gonna make products based on these concepts in the future.

So why should you care. Well, first of all, because it's cool. I mean look at this thing
it's a phone that unfolds into a giant full size tablet. And it actually turns on and runs android, it's like a science fiction prop. But it's also important,
because TCL is planning on eventually making
foldable and rollable phones that might actually look like these. Possibly as early as next year. The company says that it's
experimenting with dozens of different form factors right now.

So it's possible that phones like these, could be real one day. Look phones have basically been the same for the last decade. Black boxes with touch screens. Devices like the tri-fold
or that sliding concept, even if they're not here yet, show off what the future phones might one day look like. And that's really exciting idea. Thanks so much for watching. If you want to see more videos

Samsung Galaxy Fold Teardown! – How does it even work?

today we're going to take apart the galaxy fold this is the phone from samsung that opens up to show off a full internal display tucked inside the two halves since my inner screen was damaged during the durability test and is a bit finicky now my question is can i disassemble the phone and just keep one half of it as a functional device because technically there is that one screen that still works on the outside it should be an interesting little experiment let's get started so there are three surfaces to this phone the large square inner screen and then the two long rectangles that are located on the outside samsung phones are typically taken apart by removing the back glass and this galaxy fold appears to be no different with a bit of heat from my hika and a bit of fancy finessing from my razor blade along with the suction cup i can gently work my way around the back glass panel slicing through the adhesive it's a tad difficult since the glass is curved but not impossible after the majority of the adhesive is cut i can twist off the only piece of this phone that doesn't have a screen attached and pull it away from the phone there are no ribbons or anything sensitive attached to the underside of the glass we do get our first look at the wireless charging coil which i totally forgot this phone even had now we have two sides left i'm going to assume that this phone has more components under the smaller display so i'll grab my suction cup heat gun and razor blade and work my way around the glass once again taking special care not to put my razor blade too deep into the phone because if the screen gets poked from the underside it'll be dead the screens are very fragile as we learned from the folding screen inside of this phone after the adhesive is warmed up and cut away i can tilt the screen up and away from the hinge side folding it open allowing access to the thin ribbon cable plugged in underneath the black plastic cap once i unsnap that like a little lego the front screen and glass panel can be removed it's a super thin compact little design oled screens are as thin as they come it's the same style of screen we saw in the back of the nuvia x and now we know that samsung can do dual screens maybe they'll start adding front and rear screens to their other phones just because they can no complaints here there are 19 visible screws holding down the internal back plastics to the phone and three more screws hidden underneath the wireless charging flap after those are removed the wireless charging can be pulled away this has the circular wireless coils in the center along with what looks like nfc coils all of which can communicate through the gold contact pads that rest up against the motherboard now i can remove the black plastics from the right side the top section has a built-in loudspeaker along with a separate earpiece speaker kind of interesting that they are both right next to each other then we have a plain black piece of plastic that brackets around the battery and lastly we have the bottom plastics which contain the loudspeaker one cool thing about this little speaker just like we saw inside the iphone 11 pro are these little white foam dots that fill up the space inside of the speaker box the lightweight specs are added to the speaker housing to dampen the speaker as the speaker moves air inside of the speaker box has to pass through the foamy dots causing the air to scatter and act less dense which then allows the speaker to sound bigger than it actually is people have been adding foam to subwoofer boxes for years so it's interesting to see the same concept applied here on this subwoofer for ants someone should count these for us you might have noticed already that this phone has two batteries inside a smaller little guy off to the left and then a relatively proportional battery on the right side i'll unplug each of them just like little legos removing the battery is the same dangerous tedious process that it always is with samsung's even on this futuristic galaxy bold samsung still hasn't updated their battery adhesion practices with two pry tools gently leveraging up the battery i can finally remove it by hand but any accidental bins would either cause the battery to just slowly expand over the next several months or explode immediately it's a fun little game that keeps you on your toes i'll remove the extension ribbon over top of the smaller little battery and then commence the same gentle prying procedure while hoping nothing spontaneously combusts the small battery is a milliamp hour and the larger is a 2135 for a combined total of 4235 milliamp hours something i haven't noticed before is that both of the motherboards inside the galaxy fold kind of glimmer with a rainbow effect like a gasoline drip in a wet parking lot it must be some kind of treatment that they use while assembling the boards it looks super cool i really do think that sometimes the insides of cell phones look cooler than the outsides thumbs up to samsung for that one speaking of internals here's a close-up shot of the guts for those of you with a galaxy fold you can screenshot this crop it and make it a wallpaper back to business it's time to see how this hinge works and how it was able to withstand my bin test the sim card tray does have a rubber ring around the lip but there's definitely no ingress protection rating on this phone since dust can still very easily get inside at other points i'll remove the three large ribbon connectors on this half of the motherboard remember that this is also the half of the phone that the smaller rear screen plugs into there's one more phillips head screw holding the motherboard down and then i can lift up and unlatch the last little ribbon on the underside before pulling the motherboard free the shimmery motherboard comes out with the outer camera still connected it's a 10 megapixel camera with no optical image stabilization there's also a large magnet along the side and up in the corners this helps keep the phone closed but it's pretty well balanced without being too strong or noticeable i'll unsnap the two large motherboard extension ribbons from the other half of the phone along with the side button connector and i can pop out the two internal front-facing cameras remember there are six cameras in here these little guys are the 10 megapixel main camera along with its 8 megapixel depth sensing sidekick neither of which have optical image stabilization after popping off the two bottom signal wires the motherboard can start lifting away from inside the phone and once it's out we get our first glimpse of the copper cooling pad underneath the board the motherboard doesn't have any thermal paste but it does have the foam pad to help transfer heat the triple camera setup on the galaxy fold is very similar to the galaxy note 10 with its 12 megapixel two times optical zoom camera down at the bottom then the 12 megapixel main camera here in the center that also has optical image stabilization the main camera also has the little variable aperture gizmo it can magnetically adjust how much light can enter the sensor with its little circular shutter thingies pretty cool the 12 megapixel wide angle camera up top does not have any optical image stabilization remember how i was going to take this phone apart and see if half of the fold could still function as a full phone well both sides do have a battery and one half has an extra screen so it was a good theory but the problem is the small screen is on the opposite side of the usb-c charging port so the galaxy fold definitely needs both halves of the phone to still function who would have thought the copper vapor chamber can pry out of the phone easy enough this little guy just dissipates the heat from the processor allowing the phone to run a little cooler we've seen this kind of copper inside of a lot of phones at this point so let's keep going it's time to check out the massive internal 7.3 inch amoled screen and the complex hinge contraption that holds this whole thing together now you probably remember that this is the second time the galaxy fold has been released the first time it launched there was what looked like a screen protector on top but was actually part of the screen itself samsung has since extended that screen protector looking plastic component of the screen up underneath this plastic bezel so people now won't be tempted to peel it off my temptation to peel the screen off though is still pretty strong so let's proceed the screen is paper thin this time and well you know it's foldable it feels like a giant piece of thick packing tape just peeling away from the phone body and it's rather satisfying samsung has added a metal plate under each half of the phone on this new version and this is supposed to add a little bit of structure to the screen at the same time while not allowing any dust to get behind the display to cause damage since the phone body is not dust proof samsung has said that anyone with a samsung fold can replace that inner folding screen during the first year for a one-time fee of 149.

Which seems more than reasonable but if you happen to break the screen more than once or after that first year it'll be 599 funny how samsung can replace the whole screen for the same price that apple's charging to swap the back glass of an iphone 11. now let's take an up close and personal look at this hinge this floppy boy survived my durability test and i think it's time we found out how and why there are some pieces of long thin black tape covering up the internal screws i'll pull those away from the galaxy fold so we can see more of the impressive engineering we can also see some of the sand that slipped up inside the fold this is still causing a grinding noise as the phone opens and closes let's take things a step further the hinge of the galaxy fold is made up of three main components the first of which being the massive back metal spine of the fold and it's held in place by ten screws once those are removed the spine can be pulled from the center of the phone its metal design has chambers or ridges inside to help guide the other components of the hinge it keeps them from bending too far or rotating out of place here in the center we see the inner gears inspired by watch mechanics along with three of the four spring-loaded clasps that lock the fold into the open position it feels extremely well balanced inside of the fold we get these metal interlocked shovel looking gizmos two large ones in the center with two more smaller versions of both the top and the bottom there are a lot of moving parts inside of this thing which does make it feel very balanced and natural while also being incredibly sturdy but with all the precision that these moving parts require there's not very much room for any specks of sand and currently sand and dust can still get inside and grind away to their little heart's content so while this hinge design was inspired by watch mechanics hopefully samsung can also seal it up like watches are in future versions of the fold i think it's an awesome innovation and it's good of samsung to take care of their customers by offering replacement screens for so cheap during that first year i look forward to seeing what other versions of the folds come out next personally i want to see a smaller fold that opens vertically into a normal size cell phone kind of like the old school flip phones it'll be fun to see what happens do you think folding phones are ever going to catch on and be mainstream let me know down in the comments hit that subscribe button if you haven't already and coming out me on instagram and twitter thanks for watching i'll see you around
