Apple sued over iPhone's liquid sensors

by Jim Dalrymple

A class action lawsuit against Apple is alleging that the company relies on a faulty technology in its iPhones and iPods to determine whether a device has been exposed to liquid and can be repaired under warranty.

Filed in the Northern District of California by Charlene Gallion on April 15, the class action lawsuit claims that the Liquid Submersion Indicators technology that Apple uses is inaccurate, which could lead to false positive results.

The Liquid Submersion Indicators are triggered when liquid has entered the device. The indicators are located in the headphone jack and in the dock connector housing of the iPhone 3G and iPhone 3GS.

If an iPhone or iPod Touch is taken into Apple for warranty work and the Liquid Submersion Indicators have been triggered, Apple can refuse to fix the device under warranty. Obviously, false positive triggers under this circumstance would not be beneficial to consumers.

According to Gallion, this is exactly what happened to her. Her iPhone--purchased in 2008--stopped working properly in March 2009. She contacted Apple about getting it repaired or replaced under the device's standard warranty, but was told that the Liquid Submersion Indicator had been triggered. Subsequently, she was not entitled to a repair or replacement under warranty.

According to the lawsuit, Gallion did purchase a discounted iPhone 3G from Apple to replace her broken device. Six months later, that phone stopped working too. Apple again told her that the Liquid Submersion Indicators had been triggered.

Apple says the technology is designed so it won't be triggered by humidity or temperature changes, but the lawsuit claims independent testing proves otherwise.

The lawsuit says that the Liquid Submersion Indicators can be triggered by cold weather and humidity, both of which are within Apple's operating standards. The suit claims that other types of moisture like sweat during a workout can also trigger the indicators. Problems with sweat causing some devices to stop functioning have been reported.

An Apple representative declined to comment on pending litigation.

Apple is being sued for, among other things, breach of warranty, fraud, and unfair business practices. The lawsuit is asking for an unspecified amount of damages, as well as all costs associated with the class action suit.

If sweat gets inside and shorts something out, that is the fault of the owner. Why should Apple be responsible?

The other cases, where something else is triggering the sensor is a different story.

Anyway, I've brought iPhones in for repair, and they always check the sensors and they haven't been triggered. These phones have been subjected to sweaty and cold environments (inside a ski jacket for 3 days), high florida humidity in summer, and everything in between.

It's not common these sensors fail, and if it fails twice for the same person, one has to wonder how truthful she's being...

If there's a design flaw in the indicators, then it is actually likely that a person who experiences false positives will repeatedly experience false positives. They're going to be in the same environment.

Actually, it's EXTREMELY common for these sensors to fail. go look it up, and you'll easily find report after report of these sensors giving the wrong reading.

From MY experience, YOU'VE been the lucky one... not having sensors tripped after owning the phone for 6 months is very lucky.

for example, my phone hasn't been subjected to anything like yours... and yet both sensors are tripped.

unless you want to call me a liar too. but i'm not.

Some people are just unlucky with their technology.

If it really gets inside and shorts then sure, but a little sweat just touching the connector in another matter. I had an iphone that had a problem with the display not being responsive to touch in one row. No water ever even splashed on the phone, but i did have it in a pocket of some pants that were slightly damp from rain and I guess that's why the sensor was triggered and so they wouldn't warranty the phone.

Who's to say it was sweat that shorted the device.

If I can submerge a device in water let it dry and it still work then a bead of sweat should not kill a device but it can trigger a sensor.

Also isn't a big use of iPod's is for running and work outs am I wrong?

So let me get this right, because it has not happened to you, the woman is lying? What an idiotic statement.

If the iPhone is designed so sweat can get inside and short it out, it's badly designed. I mean, it's meant to be in pockets, used during workouts, etc. A device like this should be built to withstand the environment it's meant to be in - sweaty or damp pant pockets, without having to put it into another enclosure.
Mind you, I find this true of all cell phones. What's the point of making cell phones so small if I have to put into case that doubles its size just so it doesn't break in the first 6 months? Oh wait, because then your service provider will sell you a "discounted" version, if only you extend your contract another 6 months.

Some fanbois cannot accept that the product they worship may not be perfect.

This happened to my daughter -- $200 for a new phone although she never got hers wet.

And don't forget that "Loss of WiFi functionality" after the 3.0 firmware update. Many people lost the ability to use wireless with their iPhone's after that (myself included). Apple has yet to own up to that as well.

Or you can fix it yourself. Go to:
1. Settings
2. General
3. Reset?
4. Reset Network Settings

This happens all the time. I either have to disable WiFi on my phone or reboot my router. I have to do this several times a week with my phone. My PS3, my Wii, two laptops and an HP slimline PC, 2g iPod Touch and a Chumby all work flawlessly over my WiFi network... my iPhone 3GS glitches constantly though. I've been told to get a new router. I don't see that as the problem... especially since it's a .n router. How much newer can I get? :]

My iphone has a broken silence button and I brought it in under warranty more than a year ago. My warranty claim was denied due to a triggered sensor at the bottom of the phone.

I am still using the same iPhone today, unrepaired with a broken silence button. Clearly the bottom sensor is bogus due to its location and I will be moving to an android phone in a few months after my contract is up.

HOW DARE THEY require that a company comply with its own warranty! How dare they demand that a company not refuse warranties based on unprovable, potentially faulty claims of abuse. Are you folks with me!?

This is a design problem. Since these sensors do trigger off of air if it moist enough (SF fog, anyone?), most companies put the stickers behind the battery, not in a convenient location for exposure to air, such as right by a port.

Wrong. Just throw your iPhone in the toilet and never buy an Apple product again.

Wow, I'll forgive your ignorance since you probably know little about product quality assurance and failure trends. When a fale positive is triggered by a situation (such as fog, humidity, position device is stored in), it is of significantly increased likelihood that the same user will experience another false positive unless they expressly change their behavior patterns and environment.

As cometman said above... "If there's a design flaw in the indicators, then it is actually likely that a person who experiences false positives will repeatedly experience false positives. They're going to be in the same environment."

This is all very true. A simpler example. My tires on my car are warrantied for say... 10k miles. Just for the sake of an easy number. If there is a problem with the batch causing them to lose tread by 5k miles in some cases, I, a person who drives on gravel roads often (which is harsher, but within warranty specs) and commutes 40+ miles a day on the highway, may experience this failure earlier and with greater likelihood than grandma who uses her tires to go grocery shopping once a week and accumulates her 10k miles over several years.

Where are the sensors located, and how can you tell if they are triggered? I have no problem with my iPhone currently, but now I'm curious. Can they be examined without opening the case- which would void the warranty anyways?

if using one of those ear scopes that the doctor has you can see them better. I dont know exactly where the one in the headphone jack is, but the dock one is under the dock connector if it hasent been triggered look for a white half a moon hole under the dock connector on the iPhone.
by fudbuster77 April 26, 2010 5:46 PM PDT
Oh wow... those ARE hard to spot. I would never have suspected them to be there until you pointed them out. Those are pretty well hidden from casual inspection. I had use a strong mini flashlight to spot them.

I don't know what the Apple warranty says in the US (I suspect it is nearly or exactly identical to the Canadian one), but if I recall correctly from when I read the Canadian warranty after the moisture sensors on my iPhone were triggered, it does NOT explicitly say the warranty is void if the sensors are triggered.

What it does say -- again, if I recall correctly -- is that any damage caused by a list of things, including moisture, is not covered.

Apple appears to have a policy that they will not cover any otherwise warrantied issue if the sensors are triggered. (At least, the first thing they do when I walk in with my iPhone is to check the sensors and declare that the warranty is void because they have been triggered.)

I will leave it to readers here to determine whether they think that a triggered sensor = damage CAUSED BY moisture. I, for one, do not, since a rain drop will trigger the sensor, regardless of whether it penetrates into the innards of the phone. I base this belief on the fact that my iPhone works fine almost 9 months after the moisture sensors were triggered. Clearly, whatever event triggered them has not caused any observable damage to my phone.

Read your warranty and don't assume that a sales clerk knows what your legal rights are. If in doubt, talk to a lawyer.

You are right, while a triggered sensor MAY indicate moisture penetration, it does not follow that the moisture penetration is the cause of the problem, only a possible cause. And if the sensor is already triggered in many phones that do still work well, it stands to reason that it would be hard for Apple to claim moisture exposure is automatically the cause of whatever problem people bring their phone in for.

Apple never take any responsibility for these sort of things. The G5 iMacs failures, Time Machines failing? 12 month warranties? Just pretend it isn't happening and the fanboys will cover it al up with the usual litany of excuses.

Actually Apple is usually better at this stuff than most companies, I had a hard drive on the first generation black iBooks die on me 2 months ago, and of course it's out of warranty Apple replaced it for free. I've only had one experience where they didn't replace something which was the faulty ATI Radeon x1900xt that I bought with my Mac Pro it was prone to overheating which caused display problems.

Actually, according to the 2010 Consumer Reports computer and electronics survey, Apple's customer service is the best in the industry. The second best, Lenovo, scored 23 points behind Apple (on a 100-point scale); Toshiba scored third, Dell fourth, and HP, fifth.

I realize that it is trendy and fashionable in certain circles to hate on Apple, and that some people believe being an Apple hater gives them some sort of counterculture street cred or something. But saying "Apple never takes responsibility" just makes you look uninformed.

the only thing about apple is that since they usually don't have as many problems as other brands, its a big deal when something goes wrong so everyone complains. fact of the matter is, other brands give so much trouble nobody really cares. its a given.
by aphoog April 26, 2010 6:02 PM PDT
I will give you that Apple products are the best in class - not because they invent something radically new but because they find a radical way to present an existing technology. It is not so much about the features but about user experience. Now that being said it will be foolish to expect Apple users complain about poor customer service. I will be the last person to complain if i spend (justifiably or not) double or triple the normal amount for any product. Apple's customers have already bought into the "Apple is better than anything else in the world" mantra and cannot be expected to find fault (refer to comment #1 by ikramerica-2008). Ever heard a Ferrari owner complain about the car's seat? and yes... Apple is the Ferrari of the technology world (from a loyal Windows and iPod Touch user who has had exposure to Macbooks)
