Haha, that's kinda cool and a good way to reassure yourself before you do anything drastic.

I chose the 'go hard or go home' approach and the first day I had my phone I dunked it straight into the fish tank for 5 minutes and took pictures of the fish!
[Xperia Z3 General] mo3553:
This is cool ?
[Xperia Z3 General] Blaalad12:
Do i press on the ports? Pressure only seems to go up when i press on the display! Pressing in on the ports does feck all ha
[Xperia Z3 General] Bäcker:
No, you don't press on the ports. You need to reduce the internal air volume of your device, this can only happen by physically compressing the device. As the front and back panel is slightly flexible this is the way to go. Pressing on the ports will not do that as the frame is rigid and will not give.
[Xperia Z3 General] 3Shirts:
High school physics:

Pressure = Force/Area

In this case the area is the air in the phone and the force is your squeezing. If you increase the force but the air cannot escape and thus stays the same, the pressure must increase.

If the phone was not airtight then the air would escape when you squeeze so Force would increase but Area would decrease proportionally and pressure would stay basically the same.

That is why this is a useful test.
[Xperia Z3 General] hoprockgame:
Thanks for share brother.:good:
[Xperia Z3 General] tsachi:
If you don't want to use the code every time there are plenty of free apps on the play store that show pressure: https://play.google.com/store/search?q=barometer
[Xperia Z3 General] caqo71:
What a great idea. I have a Z1 that I suspect that back seal is compromised, so I'll test it later.

I did the test with my Z3 and it does works, even, if you open some port then the pressure doesn't rise.

Thanks for the info.
[Xperia Z3 General] :
Out of curiosity, how much should it rise? When pushing medium hard, mine go from around 1005->1020 or so. So mine should be waterproof, right?
[Xperia Z3 General] tel033:
Yes that's fine already
[Xperia Z3 General] markwparrish:
Any one else getting a slight popping sound after applying pressure to the screen and then releasing it? Kind of like something snapping back in place. I'm not even applying that much force either. My difference in pressure is rather slight. A change from around 1001 to 1007. Since it was rising with all flaps closed and not when opened I figured it was good to go.
[Xperia Z3 General] casis86:
Mine goes from 974 to to 980 tryd the service and a barometer app. Are there any numbers which i can look up to be save bevore going for a dive :D
[Xperia Z3 General] GigaSPX:

It seems like there's a hardware defect on this particular model of the Z3. Anyone else share the same problem here?
[Xperia Z3 General] caqo71:
Wich app is that?

[Xperia Z3 General] Bäcker:
very interesting find!

My 6603 also has the same behaviour. I'm not sure whether this really is a defect and the point of water entry for your device. It might be a membrane/valve to account for pressure buildup, i.e. when the phone heats up due to heavy cpu stress.

You could start a poll to find out if every unit has this.
[Xperia Z3 General] FiSHNuTZ:
Considering the number of people who have this behaviour, I'm suspecting that this is functioning as designed, rather than a defect, and is probably an automatic air pressure equalization valve, something you would need in a waterproof device. Mine does this as well. (D6616)
[Xperia Z3 General] GigaSPX:
Just to clarify, I don't have that unit. I have the D6708, the Z3v. Basically the Z2 chassis with no wrist strap holes for leakage. :P
[Xperia Z3 General] glasslung:
So it should maintain the higher pressure if you keep pressing on the screen? I have the Z3v and if I push down on the screen and hold it pressure goes up but drops back down to the baseline within a few seconds. Waterproof or not?
[Xperia Z3 General] Smartphoner:
Actually i tried the test and it does rise but when i place my finger to close the lanyard opening and do the test it rises more, that really concerns me. I submerged my previous xperias before without using this test before. I'm not sure if i could do the same with the Z3 after knowing that there maybe a design flaw in this line.
[Xperia Z3 General] meckipower:
Let us know, how the Story ended.....mine has the same Issue, the Backcover Seal is not perfect tight....If i do the Test, the Pressure increase about ca. 3mb, if i press the corner with the not tighted Seal with to fingers at the back and front and do the Test, it increase about 12mb. Im thinking about to send it to the Service.....
[Xperia Z3 General] A.M.H.Q.:
I tried this test; when I press on the upper part pressure goes from 977 to 990 and then decreases, and I press on the lower part pressure goes from 977 to 979-980 and then decreases. So, does it qualify as waterproof or not??
[Xperia Z3 General] Bäcker:
Woops, did not answer that one. I got a new Frame/Screen/Backcover AND Battery at no cost (warranty).
[Xperia Z3 General] Mr.Tom_Tom:
Could you make a short video with another device, recording how and where you touch the phone?
[Xperia Z3 General] Technologicfuture:
hi peeps,

i could do the pressure test for a few times in the last months. Now the Pressure Test is missing from the Service menu. Restart or Reboot didnt help. Did someone experienced the same or has any tipps to get it back.

Other Barometer apps dont work either.!! wtf
[Xperia Z3 General] zouden:
Same with my Z3, so I suspect that happens to all of them and the guy in that video is just speculating. We can't all have defective devices.
[Xperia Z3 General] A.Desinformation:
I'm not sure it's defective or not but when i press on the screen number is not increasing or decreasing... i was also downloaded a barometer from the play store and it was not working. But when i hold the device up numbers are decreasing and when i hold it down numbers are increasing... Do you think my device is defective?
[Xperia Z3 General] Zaiid:
U sure u don't change pressure? test it with something constant like book
[Xperia Z3 General] A.Desinformation:
Yes, it's pity but i am quite sure because i tried the pressure test with a different z3c and it worked. But really do not understand the problem, for instance i noticed a single dust under my rear camera lens also.
[Xperia Z3 General] tsachi:
On the z3v, if all the ports are closed all the way I actually have the higher pressure remaining. I had it drop before, but when I re-closed the usb port it stayed up

Edit: it does go down after a few seconds, but not immediate. Also, when you let go it will then go lower than original, but climb up within a few seconds to baseline. When the port want closed properly it went up for a second than immediately dropped and when released it went stayed at the baseline. It's very difficult to replicate a state that is just closed enough to have some increase showing but immediately goes down
[Xperia Z3 General] glasslung:
How long does it stay at the higher pressure for you? With I reseated all of the covers and it's about the same for me. It goes up but then drops down to the original value in about 5 seconds.
[Xperia Z3 General] marc539:
Looks like mine passed the test, but still hesitant to put in water :D
[Xperia Z3 General] tsachi:
It does take ~4 seconds to start going down, another 2-3 to stabilize low. If you let go and it shows lower than your baseline that's a sign that it is sealed and that it was just adjusting to the localized pressure.

Here's and example video: https://www.dropbox.com/s/jdrwvrunubandhu/ScreenRecord_pressure.mp4?dl=0 I stopped pressure around 8 seconds and the rise after that was without touching the screen.
[Xperia Z3 General] abhinav.tella:
Mine returns to base line in like 2 secs and not more than 2-3 unit change in pressure.
[Xperia Z3 General] Nathan-NL:
Isn't this bad for the phone?

And when the display turns white when applying pressure?
[Xperia Z3 General] tsachi:
This is very small pressure. If your finger turns white it's too much pressure. If you cause the display to turn white due to pressure through the glass, you are definitely putting too much pressure. The amount of pressure I apply is similar to the press and hold on the power button, maybe slightly more.
[Xperia Z3 General] Nathan-NL:
I didn't press very hard, but there was a little white spot on the screen where I pressed. It immediately disappeared after I stopped pressing. Is this bad for the display?

I have a Xperia Z3 Compact by the way and the value only raised very slightly. (1 point)
[Xperia Z3 General] tsachi:
I'm not seeing that. Either it's part of the difference in screen (I have z3v which has slightly different display) or you somehow have settings to show touch locations. What app are you using, or are you using the phone code?
[Xperia Z3 General] Nathan-NL:
No, I didn't use such an app. I used the code.

But I'm just wondering if it's harmful.
[Xperia Z3 General] xxquicksh0txx:
The screen changing colors is completely normal when pressure is applied.

Basically, you're changing the shape of the "Liquid crystals" causing them to change the way light is being refracted through them.

Light pressure is not bad for the screen.. As long as the screen itself does not crack, it should be fine.
[Xperia Z3 General] OCedHrt:
very poor qc

I just tried three phones at the store and they all leak. The third phone's pressure sensor could not increase at all.
[Xperia Z3 General] caqo71:
maybe phones got charging while you tested, if you open any cover, then the pressure doesn't rise.
[Xperia Z3 General] OCedHrt:
Nope. I opened three new from the box. Unfortunately for the third especially as it was the only one perfectly smooth on the corners.
[Xperia Z3 General] xxquicksh0txx:
I kind of highly doubt this test actually verifies the 'waterproofness' of the phone.

Just dunk it underwater for 10 minutes. If it survives, it's good. If it doesn't, warranty it. It's the only 100% way to know.
[Xperia Z3 General] OCedHrt:
The test is pretty self explanatory. If air can get out easily, water can get in. I think the third one where the pressure does not increase at all is the major concern - so I settled for the one where the pressure gradually returns to the starting value.
[Xperia Z3 General] Bäcker:
If the phone was 100% airtight the Barometer would not work to show outside changes in pressure. The barometer would then be relegated to just a seal-testing-device :D

So this probably explains why the pressure goes down and why there is a membrane/valve.
[Xperia Z3 General] OregonLawyer:
Air molecules are smaller than water molecules.

So airtight = watertight.

But, watertight ≠ airtight.

This test is pointless.
[Xperia Z3 General] Bäcker:
It's not pointless.

As you can see all Z3s seem to have the pressure increase until it goes down again. By design all the rubber seals are both air & watertight. Only the membrane which supposedly allows the barometer to work is air permeable - but the air cannot pass effortlessly.
[Xperia Z3 General] xxquicksh0txx:
If the phone was designed to be airtight, you would have pressure issues when changing altitude. What would happen if your device was assembled at sea level, and then you went to the top of a mountain? The higher pressure on the inside of the device would force it's self out, unless it was airtight... Which would then cause your phone to bloat? Possibly crack the screen? Who knows.

How do you know it's not actually the membrane you're testing? Perhaps the devices that drop slowly have a fault membrane? Maybe it's supposed to release it quickly.

You don't know, I don't know.. Only Sony does.

The only way to be sure your device is waterproof, is to test it in the water...
[Xperia Z3 General] Bäcker:
yes, we do not know. that is why we are making tests and why we come up with theories.

another user with a phone confirmed to be waterproof for hours in the sea confirmed that this test gives the same results on his device. (pressure increases, then falls back)

so it is pretty safe to call this test valid
[Xperia Z3 General] xxquicksh0txx:
Perhaps the salt water damaged the seals.
[Xperia Z3 General] OregonLawyer:
Well I'd compromise by saying that if when you squeeze your phone and the barometric pressure reading goes up at all then the phone is likely waterproof. If no pressure increase then phone is likely not waterproof.
[Xperia Z3 General] Brendo:
This test works for me. I have a crack in the back of my screen (as can be seen in one of the crack devices threads here) and the pressure works as op suggested. I've tried it in water and it is still working fine

(had done test before getting crack, for same result as after crack. with any of the covers removed, the pressure does not change)
[Xperia Z3 General] Bäcker:
the phone worked and works flawelessly, even after prolonged times in saltwater (and rinsing down with fresh water afterwards)

yes, thats also what I suggest.
[Xperia Z3 General] OCedHrt:
This is what I suspect now as well. Of the three phones I tested, one did not react at all on the pressure sensor.
[Xperia Z3 General] E66666666:
My phone just got back from repair and it passed the pressure test, looks like the people at Sony care did a good job replacing the back.
[Xperia Z3 General] zlays:
can someone clarify this for me please:

when I pres my device with flaps closed pressure rises and shortly after rolls back to normal (the way it was before I pressed the screen) and after I lift my finger it goes below the normal a bit and stabilises again...and with flap opened it doesn't show any change in pressure...is this normal or the pressure must stay above normal as long as I keep pressure on the screen?

thanks
[Xperia Z3 General] shilent:
My Z3, and my fiance's Z3 Compact behaves the same way. Many others reported the same thing.
[Xperia Z3 General] zlays:
so pressure rises and then normalises doesn't stay up as long as you keep the pressure on device?

did you tested it in water? :D
[Xperia Z3 General] shilent:
Yes and yes. I'll quote myself from another thread:
[Xperia Z3 General] zlays:
Thanks dude! cheers :good:
[Xperia Z3 General] .romdroid.:
I have the same for my xperia z2. I hope it is waterproof I have not dared to test it

When I open the flap nothing happens in the pressure test but of I close it and put slight pressure it goes up like 4-5mb and stays there until I remove my finger
[Xperia Z3 General] sygys:
There indeed is some kind of membrane behind the lanyard hole. if you close up the hole in the bottom and do the pressure test the pressure stays high. if you press the phone underwater the air in the hole is comming out. so this membrane is in direct contact with the outside. it moves out and inside with some delay because its some sort of rubber i suppose wich compensates air pressure in the device.
[Xperia Z3 General] sephstyler:
Guys, how many millibars are we talking about here?

my Z3 dual, with flaps securely closed, registers a 0.3 millibar change when i press. it goes from 1001.45 to about 1001.75...also, as I lift my fingers off, it seems to fall back to 1001.45 immediately.

This would suggest mine may have a leak, yes?
[Xperia Z3 General] Bro0z3r:
Yes, you do!

Usually we're talking about 4-5 mbars raise with slight pressure. What you are getting is basically nothing. Try it with flaps opened and it should be the same.
[Xperia Z3 General] Nplus1:
NOT true!

I'm seeing the same thing, less than 1 mbar increase when touching the screen and the pressure equalizes in about 1 sec even with the finger still on the screen. As soon as I lift the finger, the pressure drops below the initial reading than very quickly equalizes again. However, with any of the flap opened, there is not even a 0,01 mbar variation!
[Xperia Z3 General] Bro0z3r:
Well, it actually depends on how hard you are pressing it. You are right about pressure equalizing. However, being a bit rough with the finger I can make it rise 5-6mbar.
[Xperia Z3 General] Nplus1:
I have no idea, I'm never pushing too hard as I don't want to actually bend the display...

It has already been written on this topic that apparently any increase in the pressure reading while doing the test means the device its properly sealed.

With gentle "normal usage" presses I get about a 0,5-0,7, while with the flap opened it never varies more than 0,02-0,03.

My phone passed this "test" and then proceeded to fail underwater.

Sent the phone to Sony and they fixed it under warranty.
[Xperia Z3 General] Nplus1:
What kind of results or behavior did you notice during the test?

I am going to send it to have it tested for waterproofing. Not that I plan on using it under water, but if they sell it as a waterproof device, then it should be waterproof.

Trimis de pe D5803
[Xperia Z3 General] xxquicksh0txx:
It went up about 5mbar, and came back down slowly.

I use mine underwater because they say I can, so I will. And if it fails, they better fix it, or not tell me it's waterproof.

Not that there are very many times to use it underwater/around water... lol

I'm definitely not the type to use snapchat in the shower :p

[emoji1] [emoji1] [emoji1]

How much time did it take you to receive the new phone? Were you satisfied overall with Sony's customer service?

Trimis de pe D5803
[Xperia Z3 General] xxquicksh0txx:
I shipped it during Christmas, so I can't really judge the time of repairs...

But they say 14days.

The paper says they got it and fixed it/shipped it within 2 days though... I'm not sure if that's entirely accurate.

I didn't have any issues with customer service, they accepted my phone and repaired it. Never had to complain. However there was a lack of communication of "We're accepting it under warranty" etc.

I'm happy though.
[Xperia Z3 General] alextone:
Exactly the same thing happened in my test, I was just wondering if there's any difference between the different ranges of pressure change. Some one said that a 5-10 mbar change would be normal.:confused:

How about the waterproofing of your phone by the way? Did you test it with water then?
[Xperia Z3 General] Nplus1:
Honestly, since the behavior is the same (pressure increase when then touching the screen, then pressure equalization and almost no pressure variation with flap opened) I'm thinking it's only logical to say the range is not that important. The air either escapes or it does not, it can't escape "just a little" because then there would be no variation at all (like when you have the flap opened). Maybe the range difference comes from the way each phone was built (more or less gap between the parts)...

Anyway, instead of putting it under water to see if it dies or not, I'm sending it to Sony to have it inspected, especially since I saw what xxquicksh0txx experienced.

I've bought the phone directly from Sony so I have to register a warranty claim on the website (which I did), then wait for the pre-stamped packaging to come in, then send it, have it inspected see the result and get it back.

I'm currently waiting for the packaging to arrive but I'm going to keep you guys posted (it should take 2 weeks at most).
[Xperia Z3 General] bhavei:
Mine starts with 1005 when pressure is applied, it goes up to 1020, and in a second... Again thats in a second then it immediately goes down back to 1005, it even goes lower than 1000 like 995.
[Xperia Z3 General] Nplus1:
Jeez, how hard do you press on the screen to get a 10% increase in pressure reading? :o

[Xperia Z3 General] caspian_swan:
thanks for sharing, ?
[Xperia Z3 General] tseyksuli:
Just tried this on my z3 but it just jumps like 1-3 steps then returns to 1016 again so i wonder is there any risks for it having a leak some where thats causing pressure to drop back to default value? since i have glass protector on as well on front and back side :) also when holding thumb on that piece in video value wont reach 1030, it just jumps 1-3 as before and returns to 1016 again. So i hope mine has no water protection issues :/
[Xperia Z3 General] Bro0z3r:
It SHOULD go back to the previous value.. There's some sort of rubber in the lanyard hole, which is there just for that purpose (to equalise pressure in the phone with the pressure outside).. Otherwise the glass will most probably break if you dipped the phone in water..
[Xperia Z3 General] tseyksuli:
i also wonderd is it normal that like one day my pressure is 1016 then another day it's 1006 and next day it's again around 1016? and so on?
[Xperia Z3 General] Bro0z3r:
It depends on where you are. The initial number shows the current atmospheric pressure.
[Xperia Z3 General] Bäcker:
if course. Thats how a barometer works. The pressure tells you about your altitude and also the weather.
[Xperia Z3 General] tom_bombadill:
I tried this and in service test i am missing pressure sensor test here are screen shots

It is z3 dual in question.

First i have seen pressure sensor in menu but when selected didn't show any value just units (milibars) than i rebooted phone and now it is completly missing.

Case for official sony service?
[Xperia Z3 General] tom_bombadill:
Ok rebooted once more, now i have sensor, but on the test it is not reacting, not waterproof. Unfortunately phone was flying once from the pocket and has impact marks on housing, no guarantee...
[Xperia Z3 General] NotASpecialNoob:
Something wrong with the seal?

Hi, all.

I bought Xperia Z3 but just realize that the seal for USB cable/charger is not locked well but the seal for sim card and micro sd is fine. I attach the photo here.

I do the pressure test and everything seems normal. With all seals closed the meter showed around 966 , went up to 977 when pressed, 960 when released and then go back to 966 after 2-3 seconds.

I never test it on water because I am afraid that the seal will not protect my phone from the water.

Does anybody have the same problem?

Should I go to Sony Center to ask about it, probably ask for a new unit?

Or is it okay to leave it like that and test it on water?

Sorry if my english is bad. :D
[Xperia Z3 General] Bäcker:
It would bother me, although it seems to seal properly. I guess there is no way to properly seat it because it pops out on its own?

I woud visit a service center, because it also spoils the looks.
[Xperia Z3 General] NotASpecialNoob:
Yes, no matter how hard I press the seal it doesn't seat properly. I'm actually avoiding to go to the service center because there's no sony service center in my city so I must go to another city which will spend my weekend :'(

But you're right, it spoils the looks. I mean it's a high end phone. It must have a perfect look.

Thanks for the reply btw.. :)
[Xperia Z3 General] G-FACE:
The cap should be completely flat with the frame. It is not normal at all. You should claim for a new unit.
[Xperia Z3 General] MikjoA:
Thanks for the guide, I had chosen the Z3 not only because it was waterproof but it was a nice addition especially for me since my mink just love water and I was interested in taking video/pictures of him underwater.

But after seeing many people complaining their Z3 died in water I was very worried to try..

I did the pressure test and my smartphone performed as expected, I could easily increase the pressure by 15 - 20 millibars, which in comparaison, it was absolutely not possible to increase even by 0.1 the pressure inside the Galaxy Note 4, as expected.

And then I dared to submerse it in water for several minutes.

and it's still alive hehe no problem at all.

Thanks again !
[Xperia Z3 General] NotASpecialNoob:
Will do. Thanx a lot.. :)
[Xperia Z3 General] Smartphoner:
One advice; if you didn't try to do it before, try closing it the opposite way. 1st place the end opposite to the attached end then press on the attached end to seal. I think it will do the trick.
[Xperia Z3 General] NotASpecialNoob:
I have tried it. I think the seal is too big somehow but I'm not sure. Will go to service center when I have a chance. Thank you.. :)
