Over past few days I have developed a rash on my skin (mostly forearm area). I have analyzed what might of changed (foods, soaps, detergents, etc) and could not think of anything.
My wife pointed this article out this morning: http://www.foxnews.com/health/2014/07/14/report-says-nickel-in-ipad-other-devices-may-cause-rash/
I got my phone HTC One M8 on 7/5 and am considering this might be the culprit. I have emailed HTC to find out if they use nickel within the construction of the device.
Anyone else experience this?
Funny that you mentioned this, i just read this article before i came here and saw your post. Sorry im new so mods wont let me post links therefore i will copy paste it:
"Apple's iPad may be the cause of unexplained allergic rashes in children, reports The Washington Post, which cites a case study of an 11-year-old boy that was published in Pediatrics medical journal.
The Pediatrics article focuses on an 11-year-old boy who may be allergic to the nickel used in the casing of the tablet device. Following the increasing use of an iPad, the patient developed a rash that would not respond to conventional treatment.
His skin tested positive for nickel, one of the most common allergy-inducing metals, and doctors traced it back to an iPad he had used with increasing frequency the past six months. The iPad tested positive for nickel as well, according to the report.
Doctors advised the boy to use a Smart Case that covers the entire outer surface of the tablet. Similar to other reports of electronic device-induced rashes, the boy's skin condition improved significantly when he started using a case that prevented direct contact with the device.
As noted by the Associated Press, nickel allergies in children appear to be on the rise, with 25 percent of those receiving skin tests testing positive for nickel allergies, up from 17 percent a decade ago.
This iPad isn't the only device implicated in skin rashes. Earlier this year, Fitbit voluntarily recalled its Force fitness tracker after a growing number of users developed contact dermatitis from wearing the band. The rash was originally attributed to nickel in the charging port of the band, but that metal may not be involved as many users covered the nickel-containing port with tape and continued to experience a rash."

You can drive yourself crazy reading stuff like this on the internet. Whether HTC is using nickel or not, it doesn't mean you have an allergy. Could just be a red herring and a coincidence. It can be any number of other environmental factors: pollen, mold, animals, or soaps/detergent (as you mentioned), plus were you outside over the holiday weekend (could be a reaction to sunscreen, heat rash, etc.). Also keep in mind that allergies change over the course of your life. I have allergies that didn't effect me at all when I was younger. So it can be almost anything, even something that didn't give you a rash before.
I'd relax about it. Treat with hydrocortisone cream or similar. And if it doesn't clear up in a week or so, go see a dermatologist and/or allergist.
Wouldn't the rash be on our hands rather than your forearms then? Unless you have a different way of holding the phone than most people
Your best bet is probably writing to HTC to find out what metals are used in the unibody construction.

My initial reaction was the same. But dermatitis, while often localized to the exposure area, can also be a bit random and unpredictable.
For instance, the article linked in the OP says the boy got the rash "all over his body" and also includes a picture of his back (and I presume he was not rubbing the iPad on his naked back). Its possible that whatever alleged nickel-containing compound was unintentionally spread somehow or other.
Another example is poison ivy, where folks will often spread the plant's oil to various parts of their body after the initial exposure, by failure to properly wash hands or clothing. This has led to the popular misconception that the blister fluid can spread the rash to other parts of the body, or even other people, which is false.
That said, I still think the OP should not jump to the conclusion that a nickel allergy is the culprit, although it may be considered among other factors.

That actually makes a lot of sense, thanks And oh yeah, I missed that in his post.
So far I have found out:
Thank you for your email about construction of the HTC One M8 device from Sprint.
I can appreciate your interest in knowing whether the device has nickel in its construction.
Please note, however, that construction details of our devices are proprietary to HTC. I can only tell you that the device is aluminum-based.
We apologize for any inconvenience you may have experienced.

After responding in disagreement, I received this:
Thank you for contacting us again about the use of nickel in the construction of your HTC One M8 device from Sprint.
Joey, most of the components used in our devices are proprietary. We do not disclose formulas or composition of the parts to the public in most cases.
We apologize for any inconvenience you may have experienced due to any materials included in your phone.
Thank you once again for contacting HTC. Have a good day!

They don't deny!
I was wondering about getting a ONE M8 (for test purposes), and found a very cheap second hand. However the guy explained he got allergy to nickel and that it has caused him serious health problem.
However in the Q&A of the page, it also states he's in hospital (doesn't say why) with his device so he won't be able to send it before next week!? If I had an allergy I wouldn't definitely not keep to device causing it?
And so here am I reading this thread and wondering...
EDIT: Sales over so I can't post a link.

Hi there, I am currently making a magnetic floatation holder compatible with any android phone. I recently came across these threads and was wondering if anybody knew how I could shield the internal apparatus from magnetic interference? The phones are currently floating in mid air within the holder box but they refuse to function correctly due to the immensely powerful magnetic field surrounding it. Any advise at all would be greatly appreciated?
Have you tried a rubber lining? That may help...
Tried many linings
Hi, thanks for the speedy response. I have tried everything from Aerospace Aluminium, plastic, rubber and Titanium. The only material that currently works is lead and that has to be 3mm thick which makes it way too heavy. If there is maybe anyone you know that could literally coat each mechanism and distribution board within the device with lead that would be great but also impractical for multiple cellphone compatibility. I am sooo close but yet soo far. I have managed to adjust the magnetic frequency to allow minimal interference but it still leads variable damage in multiple areas. I have recently applied for a patent but I pray I can find an unknown material. I am just missing something but cannot put my finger on it. Anyways thanks for your kind response but I am 2 minutes away from burning everything......Sooo frustrating. If you come up with any ideas pweeez let me know, my brain is fried.
Thanks Guys and Dols
Thanks for your help KT, I managed to get in touch with one of the guys responsible for Maglev train magnetic composite technologies and he agreed to help me for a small percentage of total profits. It will be ready about March next year for initial testing, maybe you guys at XDA can use a few 1hundred units for testing? It seems to me this is the best arena to get a feel for the product? Thanks anyway, I will be looking into it.
???
I'm extremely confused to why u would need this... Even more confused about how u would market them...
Great Toy, Looks Alien.
Don't you just hate scratched cellphone/tablet screens. Well now(4months time in S.A) you can simply throw your phone into the invisible magnetic field and when there is no contact with the ground your face cannot be scratched. When you get into your car, simply plug it into your sig lighter and your phone etc can be held in mid air. No more key scratches, no more make-up marks on your device. And it looks really space age, your glowing Android etc phone hovering in mid air. And it will also charge automatically while in the magnetic spectrum. Use it as a night clock/light and place it on(or rather over) your night stand table.
Well at least I hope people would use this because I have spent an infinite amount of time and energy, not to mention hard capital, on this adventure of mine. The ride has been great and tough at times but hopefully the law of thermodynamics will ensure at least a 60% return on energy invested. The guys at Maglev where ecstatic so I am sure they would not help me out as they have unless they knew it was a sure bet. Anyways, thanks for the constructive criticism.

My 2c (worth even less )
It sounds very cool, and very techy and geeky, however I don't know if I see the mass market potential for this type of device?
Also I have a couple of questions:
Does the phone hold its position once placed in the magnetic field? Or is it able to rotate freely?
What about the potential effects on wristwatches and other non sheilded devices? I don't want to put my phone in a mag field and have my watch go blank.
That being said I wish you luck - hopefully I'm wrong and you can retire on this idea
Spot On
You are absolutely correct, containment, extrapolation, dispersion on a lateral effect and cross intensification are issues that are currently being worked on. As of yet nobody in S.A has the mechanical techniques nor tools that I require to enclose the radial disturbance, only one company in Germany can manage the calibration needed. And this has only recently been developed through discoveries made on the Large Hadron Collider. Fortunately, the guys at Maglev's, ITSC, have a ready made and diverse magnetic operating coil for my device. With ought going into all the technical babble, I have got a free travel package to Germany next month and they say my mind will be blown away when I see the solution they came up with. And, retirement, no way, my brain could not handle being idle for 5 seconds. These guys are brilliant, I gave them blueprints a week ago and they already have a model I need to sign off on. So I am sure all your devices will not be affected in any way. Gonna hit the waves now, have not surfed in 3weeks. I hope I can count on xda to distribute a few working units when I get back? When you guys O.K a device, it's future is certain.....
I'm a novice so this might be stupid. Your focus seems to be on insulation. Have you tried going the opposite way? Maybe construct some sort of golden faraday cage?
Also, If I got one of those testing units, that would be tits.
im not certian a faraday cage would work. but it would definately be worth trying, not gold though (gold wont conduct magentic flux very well), ferrite, iron, anything that conducts magnetism very well with very little remaining magnetic field when the source is removed (there is a property specified for that, but i cant remember the name). had part would be covering the screen and not being an eyesore. im not gonna watch the thread so OP can pm me for a bit more info if they wish.
any snap shots i know it might be a no but i really want to see this very intrested
Hey sorry, been out of town for a few days. No problem, as soon as I got the reworked casings in place I can send you a pic. Just a tad dicey at the moment due to copy right etc. Oh and brilliant, the Faraday cage worked perfectly in my initial testing +-1year ago but it blocked the entire device off and stopped easy insertion of the phone. All the kinks are pretty much sorted, you can throw the phone from 3metres away and the field will capture it. Received a vid from MGLEV tests, it was lank hilarious, I am so stoked my baby is almost sorted. thanks guys for input, how can I get in touch with xda management, want to organize initial releases for +- 1000 members? Just require delivery reception details and a few agreements, no cost to you at xda at all? Thank you, God Bless.
I think this guy is screwing with us. He sound like a back to the future movie.
And you waited all this time to tell us? (read the last date it was posted).
I see what you mean though, kinda too good to be true or, at least, too expensive to buy commercially
This is not too good to be true. The magnetic levitation technique has been demonstrated even with living beings in lab. There are adornments in market that float in free air with magnetic levitation.

However, I guess it's far fetched to use it for cellphones since the inteference and damage to components will be too high. However, I doubt the authenticity of this post as MagLev trains have little in their design that'd help shielding a mobile phone.
If scratched surfaces annoy you, use a woolen holder.
hmmm any updates?
I'd love to do testing; got like 4 different phones to test with
Shame they cant get on at them about updating it as well LOL

I actually support the verdict..when they state in the advertisement that the handset can do a particular thing, the handset should live up to it..defy's add really exaggerates the reality as there are many people whose defy's screen broke after falling for a couple of feet..so fair!!

It's not unique to the Defy, though - you can break any smartphone's screen if you drop it on a hard surface and it lands the right (wrong) way. It's not that the Defy has a fragile screen, it's just that it isn't as tough as the advert suggested. If they'd just stuck to saying that it was scratch resistant then they'd have been OK. But (a) that wouldn't have made such a dramatic and eye-catching scene, and (b) advertising people probably don't understand the difference between "scratch resistant" and "indestuctible"!
The ASA is fast becoming known for its absurd over-reach. But, here's one of best from this group of idiots:

thats exactly what i was trying to say...i am no expert, but i dun believe that the screen does any better than any other handset's screen if it falls..and if it is "supposed" to break after falling on a hard surface, they shouldn't show it as "indestructible" in the advt..
Well, if you want to get totally anal about this (which is what the ASA purports to do), the way the phone is depicted in the video is exactly the way mine has fallen -- and on stone and rocks -- several times and survived w/o so much as a scratch. Honestly, I've been impressed with its ruggedness.
The ASA has also ruled that you cannot have a photo of the Wailing Wall and say "Hi, from Jerusalem"; it has to say "Hi, from the occupied territories!" (Agree or not, isn't a bit arrogant of a non-governmental advertising watch dog to be making foreign policy?)
Best of all is when the organization "Save Darfur" was challenged by the European Sudanese Public Affairs Council (an arm of the same government killing Sudanese) saying that it was "false advertising" to use the figure of 400k killed and missing. Since this exact figure could not be proven, the ASA came out in favor of the European Sudanese Public Affairs Council.
Honestly, I don't give a **** what they say about my phone or anything else. I take it upon myself, as a responsible human being, to know not to break my own phone.
Okay guys.
So I just got my 4S back from these guys, and wow, I am honestly amazed.
I saw them on my local news a few days ago, and figured what the hell. Apparently they put your phone through a process that binds their product on a molecular level, and makes it "waterproof" I didn't think it'd work as good as in the videos but it really does.
Essentially what happens is, you pay and ship your phone to them. Within a day of receiving it, they treat your phone and send it back. (can do the express version for 10$ more)
I sent my phone in on a monday, received it back on that thursday. I then decided to put it to the test. filled up my sink (about a foot and a half deep), closed my eyes, and submerged my 4s. To my astonishment, I opened my eyes and the screen was still on! I was even able to type a message to my girlfriend telling her I was texting her from underwater xD
I then answered a call in the shower the next morning and all worked fine! Its been a week since Ive gotten my phone back and have done the sink trick countless times to impress my friends, and it still works like new hehe. just thought id share, seeing as a good waterproof case for the 4s is about 20$ more.

My understanding is they coat internals of phones & simply keeps the water from corroding intricates.
My initial question was how speaker would still operate as it "coating" not hampering its performance but its answered on websites FAQ.
My question now lies in...if they coat everything that's good BUT what happens when you switch batteries...if the contacts of the battery weren't coated I'd think it could/would short out. No?

Good question. You might have to email them on that one. I don't have to worry about it since my battery isn't "removable" lol
While I understand the application to any iOS devices because they are naturally closed.
But to other devices you get some variation of success.
The most important areas are the jack ports, speakers, mics, buttons, screws and edges of the opening-backside.
They probably coat the display too "just in case" but that should deteriorate the quality of the touchscreen.
And coating the innards is not necessary, but helps as "secondary insurance" but I'd be worried about the warranty getting void.
We need a device like the NOTE entirely Aluminium-Unibody with only the bottom lip opening up for removable battery, SIM, microSD (like the HTC Legend).

It sounds like your completely guessing at what "it" does and how its applied. I on the other hand decided to investigate BEFORE acting as if i knew what it was we are discussing.
1. Its applied via vapor,in a vacuum chamber environment, so as to completely coat inside and out, all parts of said device. The coating is 1000 times thinner than a human hair and therefor does not change the way the phone feels or functions(screen response)
2. speakers are not effected because they too are waterproofed in the same nano tech molecular bonding process.
3. When you submerge your device once coated, water does completely run THROUGH your device. Short circuit cannot be obtained because the liquid cannot make contact to the positive and negative/grounding surfaces because of said thin/nano layer of protection. although it repels liquids, it still allows all existing electrical pathways to function without flaw, and will conduct electricity thus allowing for the capacitive functions to work also.
4. This technology was not designed to make your phone "UNDERWATER" proof, and they recommend not submerging any device in liquid. In the case that your phone falls from your hoodie pocket into the toilet, you can retrieve (and hopefully) rinse your device before electrical failure/short occurs. Its a backup plan for accidents, not a solution for mobile underwater photography or social networking.
These statements are not conjecture. this is what happens when you read and investigate what youve read.
If your gonna troll, at least take the time to know what your talking about. F'in trolls!
Not trolling, just thought this was the "old" method previously adopted (was it by Vertu?).
If you call anyone a troll for showing interest then I guess you would be alone in this world as a non-troll, just saiyan
Did you even read what you wrote??? Words like "probably", and other staments like "naturally closed" make you sound like an idiot, which im sure you are not... but if you are gonna post in a category, wouldnt it help to know the subject your posting about. The information is there and one should not have to ?guess?
I on the other hand became very curious about said tech, and therefor did the research needed to contribute to this discussion.
There are no what if this happens in this case because the are selling a tested product, and have limited device compatibility - for now.
I was hoping that when i saw a new post on this thread that it was someone with valuable information, trying to fill gapps of knowledge, but it was just "what if's" and "probably's"... come on. If you want to pm me about what ive learned about this product, ill be happy to share anything else i have with anyone. I am here to learn, not waste valuable time reading conjecture based on nothing.
Hey smart guy why would you come here looking for information when you already know everything?
Even if I was still interested, I wouldn't ask someone like you (just letting you know so you dont have to constantly check you pm)

Seriously guys. This is to get other peoples opinion about the product. No need to argue
Hi, I searched and cannot find this topic anywhere, but I had an idea and I'm wondering if its dumb. Also not sure if this is the right place for it.
Betavoltaic batteries are batteries that use nuclear decay to generate power. They do this somewhat like solar panels, only the nuclear material is emitting beta particales, or rather, electrons. And a semiconducting material is used to collect the electrons and turn it into usable current. Right now they are looking at using them for pace maker batteries because the material they use is safe.
Tritium is the material they will use, the beta particles it emits cannot penetrate a piece of paper let alone skin so it is safe unless ingested. Tritium has a half life of 12 years, so they would be useful for at least 6 years. And they can be made small or large.
Could we use a betavoltaic battery to keep our phones charged? Now I know that it would be difficult to generate enough power to run the phone on betavoltaics alone, the output is very small, but what if we had a 500-1000mah battery tied into a betavoltaic battery that would trickle charge the battery when not in use?
Or maybe even just make a extended case like we have now, that have batteries in them, only its betavoltaic!
I'm just imagining never plugging in my phone again, just leaving on my bed stand, its charging away, and in my pocket all day long, charging away.
I LOVE this thought, if it were possible!
I know I could have explained this a lot better, but do you get the idea? Does someone who is more knowledgeable than myself have any comments or criticism as to how it would work? Could work? Or wouldn't work?
Thanks for your time,
-Tom
EDIT: looking closer at THIS source I listed, I realized a company already had the idea for this battery for use in cell phones. But their website is down :/
Some sources: http://peswiki.com/energy/PowerPedia:Beta_voltaic
http://peswiki.com/energy/Directory:BetaVoltaics
http://en.wikipedia.org/wiki/Betavoltaics
I know it is long but please read everything before replying
Initially, the idea sounds extremely dangerous. What if the battery is opened or falls apart and the nuclear substance falls out? You will have to quarantine the area. Looking deeper, when a substance undergoes nuclear decay, it releases a range of three things: alpha, beta and gamma. These things are quite dangerous. You mentioned beta, which is identical to an electron. If this is fired at you, it could ionize an atom in your body and this can lead to a range of things like death, prolonged critical illness etc.
You are wrong about the tritium part. All substances give off three ranges of things like I mentioned. Beta will always penetrate through a lot of things. It is alpha that won't. You may have confused the two. Alpha was the substance used to kill the Russian ambassador a while back. He ingested it and died. And it cannot be traced since it is distributed by the digestive system and cannot penetrate so cannot be detected outside the body.
Theoretically, the idea is fullproof. But it doesn't seem practical AT THE MOMENT. Maybe later on. I assume they are still working on the idea. I mean, they are working on wireless charging for gawd sake. It won't be long since this concept is a reality.
Thankyou very much for the post Tom. It feels great to reaccess the science I learnt in school. Please do not be offended by the "YOU ARE WRONG" part. Only trying to help you to improve. You may want to research into the science first. I just get a bit picky at these sort of things. After having a quick look over my stuff I could spot a few errors.
You were unlucky to get someone like me to reply with my nerdy science
Never thought I would discuss this in an Android forum though.
Hit thanks if you found this useful
Thank you very much for your reply, I did not realize there was so much to it! I'm mobile right now, but I will respond more fully when I get home tonight. I'm not offended at all, I'm glad someone more knowledgeable can explain it to me and others who might search for the same question.

It's quite easy to enclose battery (or at least radioactive part) in such a way that it's at least very hard compromise the shielding. Full metal casing and you are done.

Another false statement. It's not a nuclear fallout from A-bomb or powerplant-gone-wrong that spreads with the wind. It's usually solid piece of material, I can't imagine anyone building battery with amount of radioactive material that needed more than couple of meters to be safe. Tritium is a gas (isotope of hydrogen) and if released would quickly dissipate and be harmless. You can buy keychains filled with tritium so they glow.

When substance undergoes decay it CAN release ONE OR MORE of the three types of radiation you mentioned. Not all nuclear decay processes produces all three.
Alpha particle is helium nucleus, that is two protons and two neutrons
Beta particle IS an electron
Gamma is high energy photon
There is also (often ignored but no less dangerous) neutron radiation (stream of neutrons)
While you are right that it COULD ionize an atom in body, that's no big deal. If it damages DNA it has CHANCE of causing some form of cancer. Other than that worst case scenario is that affected cell dies and is replaced by another. Of course if radiation intensity is high enough it can cause radiation poisoning, but again I don't believe anyone would build battery that would contain enough radioactive material to cause that unless eaten.
YOU are wrong about the tritium. It can't produce alpha radiation since one alpha particle is bigger than entire tritium atom. Only things that tritium produces during its natural decay (not to be mistaken with forced fussion like in hydrogen bomb) is Helium-3 ion, electron (beta radiation) and antyneutrino which is harmless since it almost does not interact with normal matter.

Alpha was the substance used to kill the Russian ambassador a while back. He ingested it and died. And it cannot be traced since it is distributed by the digestive system and cannot penetrate so cannot be detected outside the body.

I'm assuming that you are refering to poisoning of Alexander Litvinenko, KGB agent that fled to UK? He wasn't killed by some "alpha substance" but by polonium-210, radioactive isotope. It can be quite easily traced since investigators of the case discovered who brought it to UK, where and when it was produced and where it was given to target. On the other hand it's true that it's quite hard to diagnose. Half-life of polonium is about 140 days, so it's a lot more active than tritium that has 12 year half life.

Theoretically, the idea is fullproof. But it doesn't seem practical AT THE MOMENT. Maybe later on. I assume they are still working on the idea. I mean, they are working on wireless charging for gawd sake. It won't be long since this concept is a reality.

This concept is a reality for a long time now. Nuclear batteries (betavoltaic ones) are in service since 1973 in peacemakers. The only problem is that they have very low output and efficiency.

Thankyou very much for the post Tom. It feels great to reaccess the science I learnt in school. (I am actually still using this level of science in university). Please do not be offended by the "YOU ARE WRONG" part. Only trying to help you to improve. You may want to research into the science first. I just get a bit picky at these sort of things.
You were unlucky to get someone like me to reply with my nerdy science
Never thought I would discuss this in an Android forum though.
Hit thanks if you found this useful

I suggest that you sue your school if that's where you learned this. It's quite amusing how you go on about researching the science before posting when you clearly didn't do it yourself.

Sorry about flaming, but I'm a bit alergic to people using false or inaccurate information to scare people away from nuclear technology.
For low energy beta sources like mentioned tritium lead isn't necessary. Couple milimeters of aluminium is enough.
As for authorities wanting to remove uranium I'm holding - I would like them to remove it. But it wouldn't require bomb squad, just a guy with tongs and shielded container. If such batteries started being mass produced there would have to be provided a way for user to dispose of it safely so that it doesn't end up on landfill. But since there are (at least here in Poland, or rather EU) trashcans specifically for bateries, only some mechanism forcing people to use them would be needed.
The fact that current nuclear batteries are too weak to be practical in mobile devices (or would contain too much radioactive material to be safe if made big enough) doesn't defeat my point at all. I wasn't trying to prove that this is fantastic solution - It's not. I would rather have nuclear reactor in my basement (I read something about Toshiba making self contained nuclear reactors that didn't need servicing, they would only replace whole unit after about five years) and charge my lithium batteries from that. I was just pointing out how much you overreacted about potential risks.
The only two types of nuclear batteries that would be as unsafe as you say are:
thermoelectric batteries (ball of plutonium heating itself up and thermocouples producing energy from that head - Curiosity rover has 4kg of plutonium dioxide providing it with 2kW of power, most deep space probes are powered this way, even some satelites), since they contain big amounts of radioactive materials
optoelectric batteries that contain it's radioactive material in form of fine dust suspended in gas under high pressure - if container would be punctured high velocity jet of this radioactive dust causing contamination. While this type of power generation is more efficient than betavoltaics they are deemed too unsafe to be used anywhere but in space.

So we are going to have small Chernobyl in our phones? Cant wait for it :d
Sent from my Sony Xperia S rocking JB
POOOOOLSKAAAAA BIALO CZERWONIIII!!!
Very bad idea. Too costly, too dangerous, not enough power. Maybe viable for sat phones for expeditions, but not much else.
Hey guys,
What do you think of this review.
I was chocked about the buttons that pop up so easily ?
Sauce :
If a phone has to be destroyed, I'd rather have it done for scientific purposes instead of just for views for some bald jabroni.

Lol, jabroni.
As soon as I saw that I knew I had a yinzer on my hands. He's beyond a jabroni, he's a chooch jag off!
I agree no need to do such things, it's a colossal waste.
I actually enjoy his videos. It's not as if he sawing it in half or putting it in a microwave or other stupid things people do. He's actually testing the device. Is it a little more exteme then what normal usage might bring? Yea, but it's nothing way out and I appreciate seeing what exactly my phone can handle and all that, especially compared to other phones.
As for this video, I can't lie and say i wasn't disappointed with how the U12+ did. Especially with seeing how those buttons popped off. And as someone who tears down phones all the time, hearing him question it's water resistance was also a little disconcerting. It's not going to stop me from buying this phone but one of the reasons I like HTC phones are because of the build quality. But seeing this do worse than how other phones faired and hearing his concerns did disappoint me.
And I wouldn't jump all over this guy for what he said about the phone. His videos aren't necessarily pure opinion. While he does give some opinions on how he think a phone will fare in certain conditions, it's all based on his testing and how the phone itself handled it and what he finds in his tear downs. That's all. If you got the U12+ and enjoy, even love it and think it's the best phone ever, then that's all that matters. Don't get too worked up over what others say.

Ya got me n'at. That's my point though, if I'm going to want to see a tear down (which I do, because I want to see what sort of vibration system HTC has employed here), I'll wait for a proper, scientific one from iFixit (who doesn't have one as of yet).

My gripe comes from his methodology and the fact that there are some who are still waiting for their phones. Seeing one destroyed in a non-scientific matter irks me. (Though the screen scratch testing, I have to give props to.) I can't see any day to day use where my device would come into direct contact with open flame or a utility knife.

I still don't have mine yet. Supposed to come today, we'll see.
I'd like to see an in depth tear down too since I'm sure I'll probably break the back glass at some point. I'm in highway construction and I'm brutal to my phones.

It is non-scientific, but he does this for all of the new releases. So it's interesting to see how all of the new flagships stack up to one another regarding durability. At least it did better than the U11+ though.
The teardown of the U12+:
I'm a big fan of HTC but I'm no apologist either. That was rough to watch. Things that would normally be so simple to replace on a phone are causing this phone to basically become a paperweight if damaged. At the price they're selling this at, all these "little" things become that much more bigger.
