I work for the automotive glass repair company shown at the start, and I had this idea to use our glass repair Resin on my broken phone 10 years ago it just doesn’t stick to the “glass” in phones. Even if it did fill the crack 100% you can’t fix the alignment issue so you still have distortion.

I've used something similar to that in my car windshield and it worked. It was basically UV glue that after curing hides the crack. It worked because I was able to place a piece of tape inside to help keep the glue in place while it was curing. I think the oleophobic coating in phone screens make this type of repair unviable

I work in an electronics repair shop. Whenever a customer hands us their phone to get fixed we give them a spare phone to use for the meantime. The spare phones were usually just broken phones we fixed up to get barely working for phone calls etc. If any of those spare phones had a cracked screen we would put a big amount of this UV resin on them, the cracks were still visible but the resin stopped the glass shards from coming off the screen and also stopped any moisture from getting inside the phone. I see UV resin as a big bandaid for a cracked screen, it won't look great, but if you don't want to change the screen for some reason (like how we didn't want to spend money for a spare phone) it's a really good way to keep the phone working and ensure it's not gonna get worse.

A cracked Nokia? What cracked it? A diamond?

As you said, getting the resin to penetrate cracked glass is key. Also, to make sure that the crack is invisible it has to be repaired quickly after damaging it. Otherwise the crack will accumulate tiny specks of dust that will show when sealed in resin. Which is why the window crack did not disappear.

basically avoid some sort of scam and just repair it using the tools and the parts, don’t expect to get something that is a scam like what the ad says. Just get the parts and tools you need and do it correctly…

whoever cracked that screen on the nokia must’ve had godly amounts of strength

I have professionally used such resin products to repair damaged glass in the past. There's a few things missing from this particular product, mainly the fact that for smaller repairs you need some way of getting the resin into the crack, as it won't flow in on its own due to surface tension. In some cases, this involves using a vacuum chamber (Like when repairing glass on watches), but usually it requires either the right type of crack or further widening the crack to let the resin flow in like you saw here. I suspect this particular resin is nothing more than something called LOCA (Liquid Optically Clear Adheive) which is notoriously horrible at doing what this product claims; It's meant to hold pieces of transparent material together, not fill cracks.

Just commenting to say your videos finally gave me the confidence to open my phone and replace the battery and power button. I ran into a hiccup with the ribbon cable connector on the power button being a slightly different shape, but I did some unadvisable modifications to make it fit. In the end it was very stressful, but for just around 30 bucks I was able to fix up my phone myself and now I have some actual pry tools so I don't have to open up my Steam deck or laptop with old credit cards and my fingernails haha. I've had my phone since 2017 and with the new battery I hope to have it for many more years as it is still completely usable when it comes to my needs.

I am so happy to see hugh jeffreys look at this thing i was laughing at so many times with family members.

teleshopping channels sometimes have like 45 minute blocks of just this product and its too funny

Ive been seeing these "magic" screen repair liquids in ads since i was 12. Im 23 now and these are just as much of a scam as they were in 2012. If it were this easy, tech shops everywhere would be all over it.

There is a pottery repair artisan in Japan who uses a similar product, and how he does it is heats the pottery and apparently that change in temperature "sucks in" the resin. So the idea is sound but requires a different process.

I'm very glad to find this video. Even IPA is sometime not enough to clean electronic parts (ethanol is better but more expensive), any resin which has medium viscosity never fills fine gaps, I think. But, if we can use a vacuum pump and a vinyl bag, air pressure may possibly help resin to intrude into gaps.

[Polyeith]

ive done a fair bit of research on this kind of thing and had some experiences myself;

this kind of UV adhesive (because it seems like it's literally just LOCA glue) of course works in phones to hold components together, but it is also used in screen protector applications for curved display phones. If it's covered by some sort of film, whether that be glass or plastic, it will actually hide scratches & cracks via filling them in, but once you take the protector off, it doesn't do anything. it can't really fill them in permanently, only hide them, and only if there's enough liquid to make it look uniform.

Your videos have inspired me to start repairing my own tech (Even though I’m bad at it lol) and also having a bit of fun looking inside broken tech. I can agree that the I-Fixit tool kits are extremely high quality and will last very very long. Thank you for all these videos.

0:47 isn’t even an actual iPhone. It’s a fake decoy one that you can buy in bulk

This looks to be literally just common windshield repair fluid/resin like Rain-X 600001. Which does actually make me wonder if, with a pressure injector like what that comes with, if filling a screen crack could be feasible. I wouldn't hold my breath, but this does make me wonder.

[PrototypeNumber]

It could (theoretically) work on a superficial crack, might even work well on a scratch. I'd want the little vacuum thingie it comes with when bought as a windshield repair kit. Put the vacuum thing on the crack, put a few drops in, apply pressure (if you've used one of these kits to fix a windshield before...that), and MAYBE even try some light flexing of the screen (to try to create a path for the resin to get in). I tried it once on a back glass that I knew it would never work on and...it worked better than I expected (but not enough to not tell it was broke, even from a distance). I just slapped a skin over top, then a case, and went on my way.

the windshield resin is for rock chipped windshield. it fills the hole and prevents the long thin cracks. when you get long thin cracks u replace the windshield

[joshuacavallo]

maybe the oleophobic coating stopping the liquid from fully seeping into the cracks. it might work better if you stripped the coating.
