[Q] Use pressure sensor as check for water-tightness? - Xperia Z2 Q&A, Help & Troubleshooting

I've seen on several threads that the behavior of the pressure sensor can indicate lack of water tightness.
While I'm watching the pressure sensure value, I press on the screen and I see the pressure go up. The pressure then slowly goes down to atmospheric pressure.
When I release my finger, the pressure goes down and slowly goes up to atmospheric again.
What this tells me is that the phone is not AIR tight. Air is slowly going into the phone, and the pressure equalizes.
Is this normal for this phone? Should I expect the pressure to be "constant" while I press on the screen?

I'm not sure, but the phone should be good. IP, ingress protection, states that water can still enter the phone, but at harmless values that will not affect the functionality of the phone.

Thanks!
I guess that makes sense. Water tight != Air tight.
This all started because I'm getting so paranoid from reading bad things at XDA. Magnetic port falling, little gap, failing flaps, etc.
I've had it for about a month and haven't had a single problem (14W19). Fingers crossed.

No. Water Tight ≠ Air Tight. Ingress Protection is a measurenet of Dust particle and/or Water Ingress. If you squeeze the air out of your phone the place it in water it will attempt to draw in the water or dust through any slight opening .
The phone according to Sony is IP58 (It is also rated as IP55, I don't believe it can have 2 ratings, clearly Sony don't fully comprehend IP ratings either.)
The First digit refers to particle ingress, in the case of the Z2 it's 5 (Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment; complete protection against contact (dust proof)), this also means it 1,2,3,4 proof too.
The second digit is 8 (The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. Normally, this will mean that the equipment is hermetically sealed. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects.)

I'm still curious, can anyone else check the behaviour of pressure sensor in service menu while pressing on Z2 a little?
Also, there is no such thing like amount of water that's not causing harmful effects on electronics. Waterproof phone must be 100% sealed, no water can enter. Electronics + water = corrosion begins.

From what I tested the phone is quite air tight, from an pressure test when flaps are CLOSED the pressure increases because air has no where to go like squeezing a bottle it gets tighter. But when flaps are OPEN no changes to the pressure because it equalizes immediately like a open bottle air is freely to move and stay 1atm. So if the air pressure stays the same then the phone isn't waterproof.

Mine equalizes with a short delay...interesting the phone has this kind of sensor..

pressure sensor doesnt react at all
Hello my pressure sensor is showing 982,2 +/-0,1 milibar
when i press on phone with closed or open flaps still the same... does it mean it is absolutely useless and not waterproof phone despite i bought as a waterproof one..and have already replaced second handset because of water damage from water tap...nor saying about diving it into water

1- As said before, the phone is not air tight, just water tight - and also, only to fresh water - Sony specifically states that in the user manual and in the Z2's White Paper (sort of a spreadsheet with some technical details you can find on Sony's mobile developer website).
2- The fact that your barometer (pressure sensor) goes up when you press it and then goes down (and goes the other way around when you stop applying pressure on in) is exactly the way a barometer works - it calculates small momentaneous changes (the pressure you suddenly applied) to the environment pressure around the device and corrects the value. A very, very simple way to see it is that it "understands" that the extra amount of pressure it suddenly read is an incorrect value of ambient pressure and recalculates the actual value of ambient pressure taking into account that extra amount, thus returning to the actual value of the atmospheric pressure).
In other words, the barometer you have on your device (and that is exactly what we have on our phone - a barometer, which is a pressure sensor specifically dedicated to measuring the environment - or atmospheric - pressure) uses some quite specific and technical calculations (which would be too geeky to explain here) to try and come close to the actual atmospheric pressure, correcting any sort of "misbehaviours" on the reading (which is what we do when we press the device and then let it go).
If our device was air tight, when we travel from a place at ocean level, say, from Rio de Janeiro, Brazil, to a city in a higher level, say Lima, Peru, the internal air pressure on the device would probably pop one of the ports open (or both). Hell, they would probably pop open by simply flying on a standard commercial airplane, which has a much lower internal atmospheric pressure when flying at 30000 feet (around 60% of the atmospheric pressure when at sea level).
To sum up, don't worry about the value of the BAROMETER (doesn't hurt to stress that) going up and down, it is exactly the way it is supposed to work. You do need to worry when it doesn't when applying pressure with the ports closed, like the dude above me mentioned - it may be a sign that the device is somehow not water resistant (though I doubt any Sony Service Center will accept that as a reason to replace a device - like I said, the explanation is too technical for most people to even bother to understand).
Hope this helps a bit...

The pressure reading going up then down when I press and hold is due to the pressure slowly equalizing between the phone and the atmosphere. As I press on the glass I reduce the volume inside the phone. The pressure goes up. The extra air tends to leak through gaps in the phone, though not instantaneously (because of the resistance that these tiny gaps pose to air flow). This is why we have time to see the pressure go up and then down. If the covers were open (and air was free(er) to move around) then pressing on the screen wouldn't have any effect on the pressure reading.
My point is that the barometer doesn't measure "momentaneous" changes in pressure. There's nothing in the barometer (hardware or software) that tells it "hey, this pressure increase was weird, let's cancel it out". The barometer blindly reports the pressure that it measures (after compensating for things like temperature). If it acted like you say, then real pressure changes (like what you would experience in an elevator in a tall building) would be impossible to diferentiate from "fake" pressure increases caused by pressing on the glass.
I think most of what you said is correct. I just wanted to comment on that one point, but I could be wrong here too!

So I guess there's no such a thing as a completely sealed phone. If this was the case then the phone would explode, implode, or pop the covers upon big pressure changes.
So there is always some gap that lets the air pressure SLOWLY equalize.
And the key here is the word SLOWLY. If we submerge our phone and the gaps are small enough, then water pressure (which increases with depth) would both press the covers and try to get in though any gaps. But due to water surface tension and the positive air pressure inside the phone, water will have a hard time getting in (for the same reason that liquids don't fall out of syringes unless we press on the piston).
If the gaps are so big that it offers no resistance to air flow, then water will have a much easier time getting in, as there is nothing holding it out from the other side of the gap (and we would see bubbles coming out of the phone, as the air is being evacuated by the entering water). Even worse, when you leave the water and the pressure exerted by the column of water stops, the phone body will return to its original volume, sucking in air AND REMAINING WATER inside the phone. This is bad.
So the question is: how small do the gaps have to be? How SLOWLY should the air pressure equalize for it to be considered a good water resistant phone?
Some people say they don't see any increse in pressure at all. I think this is a clear sign of a bad seal. But who has the BEST SEALED Xperia?
We might be able to come up with our own "Standarized test" to check for this and compare water tightness.
If we all use a sensor logging program and press on the screen and record the pressure curve as it goes down, we sould be able to compute a sort of "air resistance coefficient", which even if it doesn't have any useful units, could serve as a comparison tool.
This would also be a pretty easy Android program to make.
Thoughts?

The assumptions you've made are correct up to a certain point. And it all comes to the degree of water resistance.
Basically, our phone has an Ingress Protection (IP) level of 55/58. The second digit (5 and 8) is related to the water ingress protection. It basically says that the device can endure water submersion and low pressure water flow for a certain amount of time on a certain amount of depth, which has to be specified by the manufacturer. That is why, on every single marketing scheme, Sony HAS to specifically state the amount of time (UP TO 30 minutes) and the maximum depth (UP TO 1,5 m) on FRESH water. Sony is pratically obliged to stress such values due to IP Standards and liability (if it neglected to state those values, it would be subject to pretty much EVERY form of lawsuit from water damaged phones and would probably lose the IP rating even before the phone itself had hit the stores).
Now it all comes to the situation in which the phone is water resistant. Anything outside those parameters (depth, time submerged, anything other than fresh water) and that is it, no more IP rating, no more water resistance, and you, the one who submitted the phone to those unspecified parameters, are the sole responsible for the outcome.
Under no circunstance has Sony or anyone else ever even suggested the Z2 (or any other water resistance Xperia, for that matter) to be airsealed, which would be a lot harder to do on a industrial scale flagship smartphone, and would certainly not be achieved with a simple rubber seal on the ports, a specially built headphone jack, a handfull of sealed microphone, speakers and buttons and some glue on both the front and back panels. Hell, those possible ingress points (rubber sealed ports, headphone jack, microphones, speakers, buttons, glued panels) include a nearly impratical amount of variables to be researched and certainly would not be commercially viable (again, just to have an air tight phone).
When push comes to shove, it is all about the situation that it is specified to be protected - which is true for every IP-rated equipment, including industrial equipment, such as pumps, compressors, turbines, electric motors and so on.
And about the frame bending to water pressure, aluminum is very resistant. It would need a much higher depth to even begin to stress it - certainly a lot more than the plastic ports, mictophone and speaker seals, button seals and even the front and back panels can handle. They would be long gone before the aluminum frame would feel anything.

You state that the Z2 has an ip rating of Ip55/58. I thought the second number relates to water not the first. The 5 being for water jets and the 8 for water immersion.
Tiu Fiu, according to wikipedia, the first number relates to solid particle protection. The second number relates to water protection as pictured below.

My z3 shows without pressure: 1009 millibar. and with pressure 1010 millibar.
I held it under the tap for 5 seconds, and guess what, water damage. So I had to return it to sony.
But which values show that the z2 or z3 is waterproof??

guys, I got a question. I did some underwater shooting today. All ports were closed properly and before that I had already tested the waterproof feature of the phone (I washed it). But today, after the shooting there was some moisture under the camera lens and I couldn't see the pressure sensor test in service tests. Is my phone dead in terms of waterproofness or what?

waterproofed or only rainproofed

Hey guys,
months ago the S3 was said to be waterproofed with a special technology, so you could even record with the phone under about 1 meter of water.
Now Samsung didn't publish any kind of this feature, but somewhere this phone is much more resistant than any before....
Watch this video for example: http://www.youtube.com/watch?v=9xkTt0XPxkM&feature=relmfu
Yes, of course the mic got broken, but the phone itself is still completely functionable. The S3 is the first phone where I signed an insurance for it (primarly because the blue S3 wasn't available in Europe at release and I thought maybe later to switch) so I don't care much about it (handles all cases, even stupidity)... By now it got about four time in heavy rain, completely covered by water. One time I hold it under running water in the kitchen and recorded.. All no problem. The problem I see is that steady water or being dropped somewhere there get's water under the battery case and in the mic input. I'm curious if with the right case you can record under water?
Post your experience with water, but please don't experiment with it as long as you don't have an insurance where your phone is replaced by minutes!
Greetings,
Snew
This phone is not waterproofed or been treated in any way different form previous Samsung phones to make it more waterproof or resistant.
Like many other devices Samsung have probably used a hydrophobic coating on the PCB this is common practice but is not generally considered a feature as its not fool proof . I believe the correct term to use would be its water resistant

It's also got moisture-detecting test patches in several places inside, so if water is allowed to enter, you could have a big argument about the warranty!
Not sure where you read this information, but it was never claimed to be waterproof.
As most phones have to (read: are) designed to have some protection to water (i.e. walking out in the rain, you do still need to use the phone on occasion) this phone is no more protected than those. Think about it, if I put my phone in a sealed see through bag I could record with it providing the bag is sealed correctly.
This applies to anything, if it is sealed correctly it will work under water. As the entrance points for water is only through the back cover, microphones etc - if these are air tight sealed then it will be possible to record under water to a certain extent providing it is not to deep where pressure will break the phone - this in theory will work with any phone.
But there is a new sealing technology (can't remember the name) that is like air bubbles (hard to explain how it works, I'll try find a link) put in around the components so that heat can get out etc, but no water or other alien fluids/materials can enter. From what I remember, no products use this yet as it was in development from when I remember reading it. The phone is obviously not using this technology as you already pointed out the mic got damaged.
Wrap layers of sellotape around the phones entry points and record away...just don't go too deep as pressure can do bad things to phones.

this is just hydrophobic coatings there are many of them and many are already used commonly in many devices.
you are probably thinking of those new ones that have been demo'd in the last year in viral fashion like the one with a shoe and chocolate sauce for fabric.

Condensation on Camera after water immersion [FIX]

Hey guys.
Today I found myself facing moisture inside my camera after giving the Z2 a small kitchen sink wash using only the water coming from the tap.
After an hour, when i went to take a picture, it was all foggy and to my surprise, the lens was completly obstructed by condensated water.
I read 1 fix on XDA and the rest of the internet -> return it, ask for a brand new one.
Well, if you are like me and don't usually take it for a bath or go into a pool (odd enough i had put it on the sink full of water for half an hour and nothing happened), there is a "fix" for it, which I got from common sense. What i mean by common sense is that if you heat water it evaporates, but since the camera is, i suppose, a bit isolated from the rest, you cannot just let the water go away on it's own, you have to give it some help.
So, what i did was: 1 - TURN OFF YOUR PHONE; 2- open both flaps; 3- Heat the phone with a hair dryer (i really mean heat it, so the watter does not return to liquid state imediatelly) 4 - Suck the moisture out from the left side (closest to the camera) flap with your mouth; 5 - WAIT FOR IT TO COOL BEFORE YOU TURN IT ON; 6 - go take a well deserved picture.
It goes away in a day at most anyway, it's simple science hot air hitting cold air = condensation, it's unavoidable

If the water is inside it does not come out in a day, the phone is sealed in.
Even if it did, this is an easy fix and gets rid of the water inside your phone, so your answer manages to add no value.
Nor does your so called fix

i had this on my xperia z1 after a day of been cinstantly damp and intermitantly soaked but my phone was hot from use. When i opened the ports it all cleared up within a minute

Your phone has a lot of expressly sensitive electrical components. I don't think it's advisable to heat it like this unless you want to fry components and loosen the glue that holds stuff together.

Have the same few days ago. And did the same without hairdryer. First cold water from sink. After pass waterproof test i got phone with me to shower. After that i saw condesation inside. I almost died,one week old phone. But i open flaps, do everything without no.3, + sillica gel for 2 days , laying on the warm heater one night. Now everything is good, everything works, indicator under microsd flap is white. I think everthing is cool, what's yours opinion?
Just got the Problem
I just got this problem.
Before seeing this post I was so worried. Now, I'm feeling relaxed.
Thanks
same happened to me, just washing grease off phone using tab water. so does this only effect the glass on top of the camera? is the rest of the phone actually still waterproof? i'm a bit confused, so does this proof that our ip58 actually working or not? i never had this problem with my z1
Ah yes I remember that happening back when my Xperia Z initially died on me.
what would you guys recommend i do? repair it or just give up on it?
I have new phone, the old one wasn't waterproof. So if you can - repair i think.
thanksss ..
I've done so many ways to eliminate the moisture in my z3 lens .. with the rice , silica gel .. and it still kept coming back
but with your way , the moisture inside my phone immidiately gone and the way is logical as well ..

I did the same thing only I used a vacuum cleaner instead of my mouth
For the common sense; the phone turns itself off if it reaches to almost 100°C. If a passively cooled CPU is allowed to reach that high it means the back cover which is supposed to handle both the heat of the SoC and the battery, is also safe against temperatures that human skin can not.
I believe hair drier makers are also aware of human skin's sensitivity to heat, and design their products according to that.
So using a hair drier to a mobile device not more than you use it on your hair, which is generally wet with the risk of over heating, from the same distance should make no harm on the device.

I used my table lamp to heat the water.
Thank you badjoras, it works for my z3 that I have left at the bottom of the pool for 5 minutes. The condensation occured even after the phone has successfully passed the pressure (barometer) test before swimming. I used heat gun from a safe distance (30-40 cm) for a few seconds before sucking the air using my mouth, and repeated the procedure for three or four times before all the water disappeared.

Camera dust

I got some dust particles on the inside of the lens which really annoys me. Due to this the camera does not focus correctly.
I really want to keep the phone waterproof so i am afraid to take it apart to clean it. Anyone experience similar issues or even swapped the backcover? Any recommendations for a backcover that ensures waterproof ability after swapping it?
thanks!

If you're getting dust under the lens you're obviously not water tight. I have ordered a replacement back and it cracked just picking it up. I don't know how fragile the original is but I'd be very careful while removing it. New seals can be bought for a few bucks.
not sure where this came from - the body is 100% waterproof...maybe "dust" particle is not the correct explanation
maybe is scratch dots from keys in you pocket?
it abit look like dust...
i mixed my pockets by mistake and left few dots maybe u did it lots of times.. ( i know the lens is plastic and not scratch resistance ) so i try to avoid keys in the same pocket

the scratches on the outside of the lens are no problem since the sony coated this and also polishing is working quite well. also i checked this several times with a magnifier.
i have uploaded a picture of the particle that causes the faulty autofocus. at the picture on the right you can see that this is on the inside of the lens.
since the phone is waterproof this is quite clearly a production fault but since i need the phone for my everyday work and life issuing a rma at sony is no option for me.
i was just wondering is someone else experienced anything similar or swapped the backcover and tested waterproof
You can test your waterproofness of your phone to do the pressure test in the service menu.
Go to dialer and dial *#*#service#*#*, go to service test and then pressure sensor. The value indicated on the screen should increase by pressing on your screen when the phone is still waterproof.

How much does yours go up? Mine started at 997 millbar and goes up to 1002 millbar max when I started seeing discoloration from pushing the LCD too hard.

that's fine. Mine is also just a few millibar. try it with the simtray flap open. It won't increase a bit.

the scratches on the outside of the lens are no problem since the sony coated this and also polishing is working quite well. also i checked this several times with a magnifier.
i have uploaded a picture of the particle that causes the faulty autofocus. at the picture on the right you can see that this is on the inside of the lens.
since the phone is waterproof this is quite clearly a production fault but since i need the phone for my everyday work and life issuing a rma at sony is no option for me.
i was just wondering is someone else experienced anything similar or swapped the backcover and tested waterproof

Hi
I have had the same kind of dust in my XZ5
I sent it back and they have exchanged with a new device.
Manufacturing issue... It could happen
Sent from my HTC 10 using XDA-Developers mobile app
since sony support couldn't offer me an adequate solution for their manufacturing error I decided to find a solution by myself.
primary most important was for me that i do not open the device.
I got rid of the particle by freezing the phone in the freezer for 20min and tapping on the lens. The particle fell off and now somewhere i do not care about )
if someone has a similar issue this might be also an alternative solution
Same problem here. It supprises me the presition in which this product was conceived with programmed obsolescence. Just after guaranty ended I began to notice blurs and dust.
I suppose gaskets became less performant as they get harder and they can't hold pressure changes anymore, like when you take a plane or enter a tunnel in a train.

I have the same translucent gray dust spots on my rear camera, and tapping and bumping with strenght makes them moving around. Of course this is programmed obsolescence.
Moreover they fill phones with glue and adhesives for "water-proofness" purposes... but after 2 years of daily use, noone sane minded would submerge any phone and if you have the need, you can't easily fix anything inside the phone or change battery if you aren't a technician , because you have to use professional tools to melt glue and move parts.
That's the current world of "water-proof", thin smartphones.
Something must change if we don't want to swim in oceans made of electronic rubbish in the near future.

Everyone Participate Please
I'm about to buy this phone so just wanted to make sure if anyone had issues with waterproofing or water test fails like previous Xperia phones.
Please give me your experience with this device in wet conditions
So far I have found the Z5C has way better waterproofing than the z3c, as you are not needing to move the flap to charge the phone all the time
I have used my phone in the ocean (even though it is not specifically designed to be used in the ocean) and washed it off with fresh water afterwards multiple times, and it works like a charn, no leaks or condensation
@nzzane
Great to hear!
Headphones and sound issues till dries
Also, a kind of obvious note. You will have to wait till the phone dries to charge it, and sound quality will be a bit muffled due to the water (until it dries)
@smardu @nzzane
I can live with that
ill recommend to put duct tape on the string hole
i found on my test water can enter from there only
@Superrman
Are the string hole and flaps connected like open tunnel between them (considered faulty units)?
showers, rinses(not washing machine, just tap or hose), thunderstorms A+ for this phone so far!
Sound does get muffled in direct spray and the occasional water drop changes the song lol but all in all had the phone for a year and could sell it as NEW if needed
@Tingles
I guess Sony waterproof smartphones are getting better and better!
rip
I ran mine under a tap and five minutes later the screen stopped working lol.

Were you able to fix it?
Waterproof??
Yea so I got my z5c back from repair and somehow I damaged the screen with water when running it under a tap. So I guess mine wasn't that waterproof...

Our device has these ratings
IP6X. Dust tight.
IPX5. Protected against low-pressure water jet spray for at least 3 minutes.
IPX8. Protected against the effects of continued immersion in water at depths greater than 1 metre. The exact conditions are specified for each device by the manufacturer.
Here's the address for proper precautions for our device, plus some other info.

Although now that you have had it repaired I would be a little more delicate with that device.:fingers-crossed:
When your phone gets opened, generally consider it to lose its water proofness. However I have been able multiple times using hot glue to perfectly seal it again.
Remember there's an easy and reliable way to check if your Xperia is water proof: Xperia Water Resistance Test

What happened to my Z5C screen????

So, long story short, my phone's battery had a sudden death. After I had it serviced by a 3rd party company, it came back with the screen somewhat damaged.
Here are some pictures for example, using the display service test:
I can't prove they did it because I simply couldn't turn the phone up until they replaced the battery. The battery might have leaked or something. They obviously didn't take the blame for it, but they also messed up the usb port so they are definitely a potential suspect. But, if they did it, what could be it? Looks like it got stained or wet or something... Definitely weird.
That kind of display issue is typically caused by a polarizer that is warped, usually caused by applying pressure to the display when it is hot. It's an all too easy thing for an inexperienced or careless repair person to do while the phone is face down on the bench, especially if they heat the entire device to loosen the seals, not just the back, or if they cool it down too quickly. It's even more common if the LCD itself is removed, but they should not have needed to do that to replace your battery. You may be able to improve it some by putting if face up, using a hair dryer to slowly heat the display a bit (not too close and moving continuously), and then letting it slowly cool down. If you have a screen saver installed, remove it first. You may be tempted to try and "work out" the warping. You are much more likely to make it worse if you try, so I don't recommend it. If you do nothing, it may slowly reduce on it's own as well.

That might be the case. I can see the patterns shift a bit when I apply pressure to the screen. What is a way to confirm this? Could I do something with polarized sunglasses or something? If that is correct, the areas affected should darken/brighten differently from the rest of the screen.
I didn't try to mess with heating the screen up. Like you said, I might make it worse and I'm already really pissed about it. But I kinda want to try anyways. Where have you seen this before? Is it possible to fix it without opening the phone?
It's more common on tablets than phones, just because of size. I've seen it on screens that have been sat on but didn't break, but heat in combination with pressure is the more typical culprit. The sun or a hot car might do it if the heat was uneven, but I've not seen that. I'm not sure how you could confirm it. Maybe some sections will darken faster as a polarizer is rotated toward perpendicular to the polarized axis of the screen. Essentially, the glue layer between the polarizer and LCD panel is thinner in some places than others, so the polarizer is on a slight angle. In those areas, there is more polarization, and you see a darkness. The only real fix is to replace the screen assembly. The steps I gave will typically just help reduce, but never fully eliminate, the issue.
Unless they did a full, written inspection of the phone before you left it for repairs and you did a full inspection before walking out with it and noted the discrepancy then (which is always a good idea), your repair person is likely to continue to claim they did not do it.
The phone wasn't like that when the battery died. For obvious reasons, the screen couldn't be inspected before the company made the repairs. So I can't say it was their fault, although I'm pretty positive that it was. The suspicion is big because they also messed up the USB port pretty good. But, again, I can't prove it. It sucks because I wanted to sell the phone, and it was in pristine condition.
