Hey hugh, certified samsung tachnician here. I love your videos and your extensive knowledge.

I love that companies REFUSE to use screws to hold down the rear cover, but literally cover in the insides with screws and then glue the battery in place, where they use plastic clamps to cover a connector. It is like they know which parts will need to be replaced and have made those parts as hard/dangerous to replace as possible...

[@osamu_90]

Not trying to defend these practices, but you can't use screws to hold down the rear cover unless you fancy marketing a phone without water resistance (which I don't think is going to sell well at all).

@@osamu_90 Uh almost every electronic appliance that needs proper water resistance is held together with screws and rubber gaskets, there is no need to glue shit shown, it's only done for aesthetics.

When you go to do the Flip 4 note that you may need to transfer the magnets from the original frame to the new one or the inner screen may go dark when turned on.

When lifting screens you should use a iflex opening tool or a quanli opening tool, that metal pry tool with the handle is far too thick and will increase your screen failure rate when lifting. You should also inject IPA into the edges of the display as these screens are not effected by it and the adhesive with heat and ipa will literally fall off.

There's also something called a WISE certification too, depending on what level of equipment/hardware you're required to repair. Hope this helps lol

[@chrisstyles4630]

The E.U is passing a law that will stop phone manufacturers from sticking batteries with adhesive so the replacement battery will be easy to remove & replace so click off back panels may return

[@Kirusion]

While it might have 18 months warranty left on it, Samsung's flip phone warranty (Samsung Flip and Fold are in this category) doesn't cover the screen in any way, so any type of screen damage either accidental or manufacturer's defects have to be paid in full by the customer, unless you take out an extended warranty of sorts which in most cases costs far more than a screen replacement

[@平和-v1z]

Seeing this glued down phone makes me even happier for the upcoming user removable battery law! Finally, something that's actually good for the environment and consumers!

[@rayoflight62]

Great repair job. When I begun with my electronic work, first as hobby and then as career, most of the devices I worked on used vacuum tubes. Successive technological transitions were painless though; but when we arrived to smartphone and tablets, the single thing I couldn't wrap my head around was... The use of glue to keep the devices together. Use of glue has been despised for generations of design engineers. If we had our way, all smartphones would have a 3 mm bezel all around, hiding the screws utilised to keep the screen and the back cover attached to the frame. I guarantee that no-one would complain of that bezel. Glue - blah!

[@xonor13]

Yup, glue is the worst design decision for repairability, but is the cheapest for production. I miss the good old days when iPhones used to have the bezel you mentioned, that were held together by two screws. When the screws were removed you could easily suction cup the screen off popping the retention clips. However, nothing beats the age when you could just pop the back off by hand in less than a second to replace your battery.

[@beingdeeply]

Or... Screws in the back.

[@Hoptockets]

while that phone definitely wasnt touched by a licensed tech, samsung license0s do exist. Asurion, the US largest phone insurance providers paid for mine as well as my apple certification. The different screw behind the screen isnt a screw holding in the plastic cover. it holds the sim tray in place. easy to keep separate if you lay your screws out in order. i usually throw a couple thin strips of double sided tape on the back of the battery to ensure it doesnt loosen in the future with exposure to heat. i would also recommend an AOD jig, makes opening most samsungs a dream. otherwise, excellent video as usual.

[@TechDove]

I absolutely love folding phones, and the Z Fold 3 I'm currently typing on. Such an amazing device and worth every penny imo

[@czkmeister]

Even though the repairability cost of folding phones is really high and it's unnecessarily complicated tech, I just got the Fold4 with a pretty nice discount, since the shop is selling out their stock to stock up on Fold5's, and I gotta say, the multitasking capabilities and just usability alone on that huge screen is just amazing. And then you fold it in half and it fits in any pocket. It's just awesome and well worth the money I paid for it, which is about half it's original launch price.

[@stephenrusconi4781]

Thank you! Mine just broke (out of warranty), and I've been looking for repair videos.

[@HobkinBoi]

I wonder if the high temp adhesive is an anti repair measure.

[@thehellkeeper5674]

It's not. It's a very thin adhesive so it needs high temp resistance otherwise the screen could fall off if the phone were to overheat for whatever reason

[@HobkinBoi]

​@@thehellkeeper5674 I don't recall most other devices having that issue with the screen being detached like that, and they don't require extremely high temperatures to soften up.

[@thehellkeeper5674]

@HobkinBoi the outer screen on the folds is particularly thin and so is the bezel so there isn't mich room for the tape, the outer tape is less than 2mm wide

[@TheMrGamer1]

Congratulations, you are a "licensed technician"! I also noticed that the sim tray was attached via flex cable, does that mean it's upgradeable?

[@adinahirschmann3112]

I only hope that some day, there will be an available SIM tray upgrade, user installable, with a Micro SD card slot piggybacked to it. BTW, my LG V20 has that arrangement, although you have to open the door and lift the battery out to access it. BTW, my Fold 4 and V20 are networked together, along with the other wi-fi capable devices in my apartment.

[@ryanhorton9594]

Hey, thanks for the clear teardown. Im a former phone repair tech with a fold 4 that now powers off when folded. I was wondering, do you have an idea of how power is shared between the two batteries? I suspect this issue may be due to wear of a flex cable shorting when folded. It remains functional during folding if its plugged into power via usb.

[@Zulf85]

The reason I like Samsung is that their replacement parts are at least easy to source - often expensive, but at least genuine. I do find myself wary of them changing that in future with some of the things we've seen them do though.

[@thomastartu9597]

I wonder about this: could you purchase only the folding screen somehow? I have two points for asking: First up, this is because the rest of the phone is in excellent condition. Secondly, I believe getting the folding display without a frame would likely be much cheaper.

[@Rizalreez]

I am not a fan of the glue because even after you clean it, you can still see the dried glue.. Will it give a cleaner finish if you clean the glue first or it is just inevitable?

[@PanCakesAreFat]

So. There is a "WISE" certification. Which there are 2 levels. Software and hardware. It means nothing. You can be a Samsung, Apple, and Google Certified. With this Fold, I've seen this countless times. The inner screen protector starts to peel, so the customer tries to peel the protector off. Resulting in them digging too deep and destroying the screen. Samsung actually had to change the outer display adhesive as no technician could get it off with their provided display removal tool. Unfortunately my store broke quite a bit of them.

[@DigitalBhangari]

There's tool called a coconut opener / coconut meat remover, long thin plastic slicer, very useful for battery adhesive slicing

To answer your question about phone still having warranty. I bought a flip 4 that had warranty until 2025 and the hinge was popped out. Samsung is refusing warranty repairs on all those devices citing impact damage even if there isn`t any and the devices have known faults with the hinge design. Bought mine for £120 and repair cost me another £75, so £200 all together still not bad for a phone that`s £1000 brand new from samsung.

I use to work for a major US based repair company that is partnered with Samsung, and am certified/licensed to repair their phones, so yes we exist.

My guess is that whatever happened with big screen, wasn't covered under warranty, hence why they didn't just use that. I am pretty sure that internal screen doesn't get much of extra warranty, despite being so easy to damage. Could be that reason why screen was ripped off was because damage, whatever it was, caused it to not boot in the first place, so seller though to just remove damaged screen by tearing it out, and that didn't help. And because they didn't know it has to be present, they gave up on repairing it at some point and sold it. And made up how it was done by "licensed technician", likely what they meant was certified technician. I used to work on phone support of local ISP and customers tend to have pretty wild imagination to come up with terms for things they don't quite know how to call.
