Is a Repaired Phone Still Water Resistant? - Submersion Test - Tape VS Liquid Adhesive

[@ej_tech]

As someone who works in a Samsung ASP, part of the post repair diagnostics is the Water Resistance Test. It uses air pressure to determine water resistance by utilizing the internal phone barometer and a weight or an external apparatus. So hopefully in the Right To Repair future, the diagnostics tool becomes available to the public instead of seeing you dunking a phone in water.

[@cavejohnson2075]

How does Samsung test the water resistance for their folding phones? I imagine those phones would only have one barometer still right? How'd you verify both sides are sealed?

[@zee9276]

@@cavejohnson2075 curious to know the answer to this as well

[@Jordan-zh7ev]

The barometer can be utilized by third party app, though I'm not sure if root is needed

[@loganmacgyver2625]

Ah yes, the infamous cube. We had one in the repair center that had a fingerprint reader calibrator which was finicky beyond words

[@graealex]

Isn't the internal barometer not supposed to have a connection to the outside? Or is that a separate barometer?

[@therealdaniboi]

I recently replaced the old adhesive on my S10+ as the old adhesive started turning gooey and the back glass started falling off. So I spent a lot of time removing the old adhesive as it was VERY gooey then I used the precut adhesives from Aliexpress. Those held up pretty well even after dropping my phone in a bucket half-filled with water. The secret is to remove the old adhesive and residue before replacing it with new ones. That way the phone is properly sealed.

This video reminds me of when I used to travel to Jamaica with my family several times a year. The children loved it. Especially, chasing the baby animal and waking up early to go out with their grandfather to feed the animals. They are all professionals now and give back to Jamaica in many ways. Bless up to you and your family.

[@nhansgoofyvideos7581]

There are ways to relatively test the water-tightness of a phone (slightly gross): Eject the sim tray, then try to suck (not blow otherwise you might trip the water indicator) out of the sim slot. After that just move your lip in and see if it holds the suction or not. Keep in mind, the phone is dirty, so sanitized the phone before and after the test. And if you can test using the internal barometer, just use it instead. The test above is only mostly used with iPhone as it does not have any diagnostic menu easily accessible and downloading an app when you have to check someone else machine on the spot is a big hassle.

[@npoaccount9154]

A good suction is good I suppose?

[@matthewgarmendia7803]

If you sent your phone to repair, don’t ever submerge it. If done correctly, yes, the phone can still be water resistant, but some phone repair shops just leave the old adhesive or replace it with one that is not air tight sealed.

[@eddiew.4650]

I don't think the majority of people intend to submerge their phones. 9/10 it's on accident or out of their control if their phone hits water.

[@ashchbkv6965]

true because removing the residue is the most time consuming process

[@workdesu]

i wont recommend submerging even a brand new phone. period. even if it's IP68 rated. but if it's accidentally, i just wanna feel assured that it's not instant doom when the phone met with some amount of water

[@matthewgarmendia7803]

@@workdesu if it’s brand new it’s fine. If the phone is 6 months or older, has sustained some drops (even with a case) , and it has chips or cracks, it should not be submerged

[@rasmasyean]

@@eddiew.4650 Originally, you got a waterproof phone to take pictures of each other in the pool. Sony advertised this all the time. They backed it up by warrantee by doing an air pressure test if you sent in a water damaged phone to rule out it wasn't negligence like unclosed covers. But they stopped the warrantee shortly after prolly due to too many claims. A new phone is likely sumbergible for a while until you break the seal somewhere due to wear. I'm sure weather is a factor too.

[@busterscrugs]

I work on cars, and I've always wondered if using RTV silicone would work. That stuff holds parts together pretty well, and it''s very good at sealing!

My Mom put her Pixel 3a XL through the washing machine, and while it seemed to be working fine afterwards, I wanted to be sure nothing got in. Since it was pushing 3 years old, I figured it was time for a new battery anyway, so I opened her up, AND IT WAS BONE DRY INSIDE. Very impressive for a device without an official IP rating. And of course, I replaced the adhesive when I reinstalled the display assembly. 😀👍🐧🐧

[@RSaiNareesh]

Couldn't believe at all 😮

[@mirkopacchioni4158]

The materials used make the difference and you also demonstrated it, nice video as always.

[@VeridianKnight]

I’m honestly surprised at how well the tape did.

[@thelightbrigadef4172]

Idk why some people assume that between water-resistant and waterproof probably same thing. Don't get me wrong, I'm not bashing this meaning. There is a phone brand that are *WATERPROOF* like kyocera, which are very rugget and designed to be waterproof.

[@Schmeichel98]

I used to have a Galaxy S8+. Bought it 2 months after it got out and went to the seaside with it. My father and my brother really like diving so one time I gave the phone to them to film the fish. Despite being in really salty water for a couple of minutes straight, the phone had absolutely no damage and is working perfectly up untill this day.

[@matthewburrows562]

Could the heat plate have evaporated any moisture from the test?

[@BrokenSmokeDks]

not really, it would have had stains

[@leandrodrace]

I always had this question on the back of my mind, very nice video!

[@keevdesign]

Wow, excellent video!! I think no one else did a video like this, and I was hoping to see one of it. Thank you for this useful info!

[@arnavranjan1913]

You should test for atleast 30 min in 1 meter of water (preferably swimming pool) to actually verify water resistance after repair. The thing you did was splash test which even modern budget phones have.

[@EdwinNikkels]

Stay positive, Hugh. Love your fixes.

[@jayzee9164]

As far as I know Rewa Technologies has a content for testing of IP Rating after repair

[@crispyjokingtuna1495]

That’s nice to know since I just replaced my screen. It makes me feel better about my phone getting wet which can happen at work fairly regularly

[@catofthekitten]

ive waited for a video like this for so long! thank you for doing these experiments for us!

[@jeremyoboe]

I have had a watch active 2 without anything coming undone. The only issue is the EKG stopped working, but that happened early on. It is apparently a known issue with many of these watches.

[@HonestLettuce]

One thing i do when sealing a phone back up is what i like to call the 're-heat method' basically once i close the phone up, i heat it up again and THEN start applying the pressure from the adhesive. And looking at my phone, if you didn't look properly, it would look as if it was never opened, the seems are that tight.

[@houseflygaming]

I work at a place called batteries plus and we repair some phones, we do iPhone and Samsungs. for iPhones we put some aftermarket adhesive that's not gonna make it water resistant as it once was because obtaining that kind of adhesive is a bit of a pain for iPhones. (Shout out to Apple!) However for our Samsung phone repairs we're partners with Samsung and one of the very few phone repair companies that has access to genuine Samsung parts as long as Samsung themselves has it in stock. Samsung parts however are very expensive because well, it's Samsung parts. Samsung however gives us the adhesive that comes with the device originally and the device WILL stay water resistant, we get more iPhone repairs though than Samsung because of the price, a new screen is expensive and you're looking at about $400 USD for something like an S21 & S22 Ultra screen. Regardless it's not that we *don't* want to add the adhesive to iPhones, it's that we aren't provided the parts to ensure it is. We've done some amazing things to bring back some phones that were believed to be completely dead.

[@usukamee7301]

So what after market adhesive DID you use at Ifixit? What name and brand was it? That's why we are here on KZbin to learn stuff...so please share..??

[@stickboy420]

you have some nice wisdom when it comes to phone repairs

[@rosaria8384]

A lot of third party repair shops often leave the adhesive, and this can affect the reputation of Right to Repair, and be used by lobbyists to prevent it from happening

[@Axel...]

I think it should be a law that, if the seller/manufacturer advertises water-resistant devices they should cover it under warranty. Why can a brand claim a non-damaged phone has water damage, and therefore not fix a boot loop, if there are images on their website with water splashes on the phone?

[@AmoghMunikote]

The only phone brand I know of that offers warrenty for that is kyocera

[@Cynth72]

I was looking for a video like this for so long

[@80sTechKid]

My s5 was dropped in liquid - it still turned on but made a sizzling noise. I poured rubbing alcohol on it, as I didn’t have a heat plate to open it. I let it to dry over the weekend and I plugged it in, it no longer sizzled. It acted normal, or so I thought. The screen was completely black, although the touch still works. I can also see that the speaker is a bit broken tho. It was never opened before - the seal must’ve gave out.

[@CarterSherman-z6n]

Loved the "highly scientific test" line! Great video, Hugh!. The heat plate could have possibly dried out any traces of water..

[@devenm4601]

that was my thought to but idk that one phone still had water in the speaker id think if the heat plate did dry any water it get the speaker to

[@TechDove]

Whenever I install new water resistant adhesive, I make sure to heat the panel to help the adhesive adhere properly since heating it helps to promote it's ability to grip, or otherwise adhere

[@JP-ig4rw]

I had an S8 years ago and fixed it with new screen after the original one broken, I have to admit that I may not be good at repairing because I broke the battery and the back glass durung the process. However, I replaced a transparent back glass that I can see if the water resistance still exists. Unfortunately the water went into the phone maybe due to my bad work, but the phone still worked good before I sold it. I think the mother board may have some solutions to make it kind of water resistantable.

[@LandoCalani404]

This is the true definition of patience.

[@tonitackerx9790]

I had the exact same problem with my Galaxy Watch Active 2. I fixed it once last year but the problem reoccured. The second time I opened up the watch fully to clean the residue properly. This is pretty straightforward but you'll need a Tri-Wing Y00 screwdriver and the microphone fell out in the middle of the process. I got it all working again though.

[@eamonnmason7014]

Great vid ta. Same background music as Tehmoan :)

[@Nitinisonline]

Hey hugh i have a suggestion that you should use any isopropyl alcohol or contact cleaner spray to clean the adhesive

[@DimaKirivel]

I also apply some heat after applying a pre cut adhesive so the glass would stick better

[@vincent.416]

Just what I was looking for! Thanks!

[@rafaeldobler8599]

try with the back cover of the iPhone by removing the cover with heat and with the laser

[@ashchbkv6965]

I strongly recommend to wipe the device clean before the liquid adhesive dries, that's because once it's dried you might pull the adhesive out the same way like pulling those battery adhesive pull tapes.

[@techyme8884]

I have the exact same watch - Samsung Watch Active 2. Bought brand new. I use it for swimming in the summer but one day i swam with it and it and after that, it kept restarting and displaying "your watch needs too cool down" and itll restart. This happened for 2 days post submurgion. Then suddenly it restarted and never turned back off. Still working great after 6months. Unbelievable how samsung claims its water resistant when its clearly not

Thing to note with actual seals/gaskets is they should be lightly greased with silicon grease when they are disturbed.

[@hyperseah]

Subscribed! This channel is so useful.

[@RenoxMTA]

I think that for the best sealing result atleast with the original adhesive you should heat the back panel after putting it on and clamp it down for a while

[@3lH4ck3rC0mf0r7]

If a fall is severe enough not just to damage the display, but also the outer frame it sits on, I suppose chances are the ability to get a proper air-tight seal on the device is also compromised, correct? So I'd need to try and find a replacement outer frame as well. I got a couple old devices like that that I am not confident to daily-drive because of this.

[@darkknight8139]

My wife had a Galaxy Watch Active2 as shown in the video. It fell apart after two years and 3 months. The display just came off. And Samsung said that there was no warranty left, but we could trade in the watch and buy a new one, plus a small discount. We thought: ok, that's fair. Guess the actual value of the watch quoted by Samsung: zero! Because it was damaged. What a disaster. My Huawei Watch GT from 2018 came as a gift with my Mate 20 Pro, because I pre-ordered the phone. They are still going strong, every day. Shame on Samsung, and a shame that Huawei is not what it used to be. I am happy to see that water resistance can be solved by yourself though, so thank you for the video :)

[@Will-pm1bu]

[@wojciechszmajdowicz2061]

@hugh. regarding your comment at the end, it's not entierly true. you can put the repaired phone into a vacum chamber and look for the pressure to drop. if the phone is sealed tight, there will be no drop in pressure.

[@jaspercas]

My apple watch series 5 screen came off because of a screen protector with very strong adhesive, I've cleaned up the old screen adhesive and used T7000 adhesive for the screen.

[@eggnogg8086]

Sort of a flawed test since you need heat to remove the adhesive, and you didn't check the cof bond of the screen which breaks easily when exposed to liquid causing it to black out or have lines, no idea if you could xray the phone in a way that you can see water inside though

[@oof56000]

I watched another video on this topic with someone testing this myth and what they found out is that if you heat up the phone with a heat gun after sealing the phone the replacement adhesive will have a better bond making it more water resistant

[@rayw8252]

Hi Hugh - Back in 2021 I created software to test the water resistance seals on a phone (unfortunately only Android, since I'm an Android developer). My goal was to help people be able to hold phone manufacturers and repair shops accountable - if the phone is advertised as IPX7/IPX8 rated, then it should be held up to that. It would be great to know if it helps you test your own repairs... YT keeps deleting my comment when I mention my software's name...

[@rayw8252]

App is called Water Resistance Tester

[@rayw8252]

The way it works is it monitors the pressure sensor inside of most modern phones to detect whether the seals are intact. It monitors for a threshold of changes in pressure when the user presses on the screen. This pressure value does not change, if the phone is not/no longer water resistant.

[@ArthurgtaX]

My galaxy watch did the same thing, but in my case I believe the fact that it is 2 years old and I took it straight from the charger and go out to work ended up causing some kind of thermal shock that resulted in the screen taking off, lucky I have the tools at work to glue it back.

[@mustafasabir12]

I had the same issue with s21 plus, due to phone heating overtime i think there are gaps in the adhesive. My phone just dipped for 1 second in a tub and that got full water in the phone. As a result all cameras, and speaker got damaged which had to be replaced. I avoid dipping phones now unless absolutely necessary like in rain time. I would not risk testing water resistance on slightly older phones, as most testing done by companies are on brand new phones.

[@WyvernDotRed]

Coming from having had a semi-smart G-Shock watch die to water damage after getting the battery changed, if assembled correctly I trust it's construction way more than this Samsung smartwatch. Lesson learned, going forth I will replace the battery myself, already did on cheaper watches but I wanted to be certain that this one stayed water resistant, as it was very expensive for what it does. But as much should be expected, such a full smartwatch has way more capabilities at the cost of lasting an order of magnitude less, both in general and battery life, assuming proper maintenance. Though similarly as to how you are using an older Blackberry, a MIP semi-smart G-Shock is a nice middle-ground of connectivity, which I found pleasant for judging whether I should check my phone.
