[Guide] Test waterproofing without water! - Xperia Z2 General

Hi everyone, this is a copy/paste from Z3 General Forum. All credits to its OP

Did you ever wonder if your device is really waterproof but do not want to find that out by dunking it in water?
Here is a test which uses just the phone and it's service mode (or any barometer app).
1. dial *#*#7378423#*#*
2. go to "Service Tests"
3. go to "pressure sensor"
4. slightly compress the phone using your thumb and index finger by pressing on the display and back
SLIGHT PRESSURE. No Berserker mode please! This is not a crush-your-phone contest!
--> if all seals are intact the pressure should rise. Your phone with intact seals is a closed system. If you compress the volume the pressure goes up as a result. If any of the seals is compromised pressure will not rise.
Note: pressure will decrease automatically - that might be a result of the sensor adjusting, it will not go back to it's original value until you relieve the pressure.
credit for the original idea goes to User Alik from the German Android-Hilfe.de forums

this only works with a pressure sensor (barometer) - does the Z2 have one?

yes z2 have pressure/barometer sensor.

then you can use this test for Z2 as well

It works. Pressure rise when pressure applied with closed flaps.
Once I open a flap and again apply pressure then nothing happens. Pressure stays the same. So, mine is waterproof. Yeeey

I tested,
start value: 1009
compress and hold: rise to 1020 and back to 1009.
release: fall to 1005 and back to 1009
It looks like mine has fault?

I get the same reading. it starts at 1014 and goes all the way up to 1022 when i touch it with my thumb, but it automatically goes back almost instantly with my finger stilll pressuring on the screen. If i open the flaps, then the sensor's reading wont change. I'm clueless!

Excellent! Thanks for the tip! Everything is perfect with my device!

It means it's working cause pressure gets stabilized

Same here pressure equalizes after a second. So its not really tight?

That's what I wondered, if the pressure goes back to normal that means it's escaping somewhere? Unless it's stretching somewhere else in the phone I guess? But mine does the same, pressure increases then normalises, then drops lower when you let go before returning to the original value. So that means it's water tight?

wow never realized Z2 have this sensor
i remember my Z1 didn't have one, it just said "This feature is not supported"

For me, too, the pressure rises, then falls back to the original pressure. Then if I let go, the pressure falls, then rises back to the original pressure.
However, this is not a meaningful test, although it gives at least a vague indication. The seals are not intended to stop the phone being able to equalize atmospheric pressure with the outside world, they're designed to stop water coming in. Most likely, when the phone is squeezed the increase in pressure pushes the seals out just ever so slightly, leaving a gap through which pressure can slowly correct itself.
A slightly more meaningful test would be to compress the phone with the doors open, then seal the doors with the phone still pressed, and then let go so that the first thing you're doing is creating negative pressure in the phone, not positive pressure.

well maybe thats not a proof ... i bought this device a week ago and from day one i submerged it three times into water to test is it really waterproof or not and yes it has done the job ...
but just trying that pressure test in normal atmosphere it equalizes after a second
while underwater i tested and the pressure increases but doesn't equalize.. so thats the point of waterproofing..
its not air proof !!
hope that could be useful for anyone ... just don't panic if in normal air atmosphere the pressure goes back to normal

My pressure just stayed at 1005. I pressed the screen and I pressed the back nothing changed I think it's because I changed the back plate recently...

Weird spot on the screen

Hi guys,
Today I noticed a very weird looking spot on the screen, or better just below it. It seems like there is some fluid just beneath the surface of the screen. I am always very careful with my HTC's, so I really don't believe I caused it... There was no pressure, I didn't drop it, I carry it in my shirt breast pocket or inside pocket of my jacket, without any other items. I really really dont know what happened - I pulled it out of it's leather sleeve, and it was there. This morning it wasn't.
Any idea if this is covered under warranty? Any idea what caused it?
Best Regards,
Lukas

I'd be STRAIGHT on to my supplier if mine looked like that! How does it look when the screen is on, cos let's face it, that's when it really matters, and probably how they'll view it when it comes to the warranty.
It's difficult to capture on a picture, but it's VERY visible when screen is on. Colors beneath the spot (wallpaper) seem washed out a little, so you get a very small color difference...
Something to do with cold weather and heating leading to condensation? I have no idea but I would ake a photo and email HTC AND your place of purchase ASAP to see if you could get a replacement, even if it doesnt bother you when the screen is on. It would bother me though, I think I havean almost OCD like quality when it comes to devices being perfect...
On a second thought, the leather case that comes with it is extremely tight, I couldn't remove my phone from it for the first few days till it stretched out! Do you think that might be enough pressure to do that to a screen?
I'd definitely get on to whoever you got this from then. That's not good!
call the waranty service ...
Mine had a weird spot as well right in the middle (and it appeared out of nothing like yours). Doesn't quite look like yours though (maybe you just caN't see it in the photo). Only noticeable at certain angles, and it looks like a colorful smudge. With the screen on it's even harder to notice it. When you press on it the "puddle" moves and shifts.
It looks like there is humidity under it. I went to the shop where I bought it, and they said that happens with some other touch screen phones, and is bound to disappear. The guy said it was due to the heat getting trapped bellow the screen.
In my opinion looks more like a humidity condensation thing.
Take it to the shop where you bought it, ask for an opinion. You still have loads of time to use the warranty, and if in 3 or 4 months it is still there or if that bothers you, just activate the warranty.
Thnx for the replies guys!

I don't think it's cold/warm/cold issue... Today I got up, put my phone in my inside jacket pocket, went down to my garage, got in the car, drove to work, into an underground garage and took the elevator into the office - phone wasn't exposed to cold today AT ALL. And it doesn't seem to be water, it's not very fluid, and there is no damp.

It bothers me massively - even when I'm NOT looking at it. The spot is also very visible when the screen is turned on.
I'd definitely get on to whoever you got this from then. That's not good!

Did that immediatly after noticing the spot - my supplier asked me to e-mail him the pictures which I did, but he seemed reluctant to promise a replacement... He said that quote mechanical damage is not covered by HTC warranty unquote. This sucks - I didn't do anything wrong!

Thnx for the reply.
The spot on my phone is really visible, doesn't matter at which angle you look. Screen off is worse than with screen on. There is no color in the spot whatsoever and it doesn't seem to be movable (if I press hard I can make it bigger, but it returns to original size after release)... I'll keep it warm for the night, and I'll see tomorrow... I could measure it, and see if dimensions are changing when temperature rises or drops.

When I heat it for about ten minutes with a blow dryer it disapears. When I stop heating it, it reappears @ room temperature... WTF is this thing?

Yes, you don't see anything wrong. For about two minutes. Then the spot reappears exactly in the center of the screen (where the 'wait' cursor/hourglass appears) and starts to grow until it has it's "original" dimensions.

Looking at the placement, it seems it's similar to mine, which is right in the center. Mine returns to the center if I press it as well.
The heat test you just did made me believe it has something to do with heat like the guy where I bought it said...
Here is another thread on the same subject (different phone)
http://forum.xda-developers.com/showthread.php?t=293311
I kept reading around, there are reports of the duct tape method.
Basically it works in the presumption the problem is both screens not keeping space between themselves. Just use duct tape over the wet patch, and pull it 20 or 30 times, and the screen should lift and the patch disappear. I'll try it and tell you if it worked.
Thank you! I'll try it as well.
Didn't work...
lol... I had to look for tape, but the tape method was unsuccessful as well on mine.
thnx anyways.
this is a capacitive touch screen so all are glass and the tape method won't work as there isn't anything to lift up unlike the resistive screen where there is a gap between the top plastic and the actual screen

Nexus One touch screen doesn't work properly when horizontal

Hi, I've now used the Nuxus One for a few days and I'm pretty happy with it and all it's fancy fetures.
The phone works flawlessly and the only minor issue I'm willing to report is the fact that when the phone is lying on the table the touchscreen doesn't respond as quickly as it does when holding it in hand..
I've also noticed that if you touch the shell of the phone with a finger while trying to use the touchscreen, everything goes back to normal.
Is it a flaw only present in mine or is it an issue that involves the capacitive touch screen of the Nexus?
Video Proof
This is the video I've taken with my other phone so it would me much clearer what I mean..
The quality is not great but I hope it will be explicative enough..
http://www.youtube.com/watch?v=hXPpyGwuSzM
mine work correctly, try it on another table
I've tried it on different surfaces but the result it's the same..
Problem is that it doesn't always do it, so it's difficult to judge if a surface works better than an other.
I've called HTC support and together with them I've done some tests, like letting another person use it the same way, but nothing changes.
I've also done a hard reset and nothing has changed so I think I will have to send it in hoping they will fix it..
I envy you in the US where you can just ask for a replacement...

Hi,
I don't think so, since I've now tried it in different environments and by different people...
This is very weired..and annoying..
I've had my Nexus One for over a month, but I recall having the same issue one day early on.
Similarly, I've had days where I can't operate the touchpad on my notebook computer because my fingers were dried out from handling solvents.
I have an associate that has a similar issue when the phone is in a leather holster case. She has to take the phone out on occasion to operate it, most while driving.
havent had any issues. Call them for a replacement
I think I will do so!
The problem is minor but sometimes can be a real nuisance..
Looks like screen isn't grounded properly.
Yes, I think so too. It must be something electrical. When I keep it in hand or touch it, the static electricity must not influence it, but it does so if I try using it lying on its own.
I've taken another video changing the surface on which I use it on..
Take a look: http://www.youtube.com/watch?v=iZ-nS_h5Pqs
I'm glad to see you're still investigating. Because the problem is so repeatable, and the fact that its not a common complaint, I'd conclude theres a something wrong with your phone.
One thing I'd try is to remove the battery for 8hrs (overnight) and see if that make a difference. I've worked with a lot of electronic devices that behave badly after receiving a static discharge. Sometimes leaving it sit without power helps the static dissipate.
But the fact that it works while on the laptop would indicate a poor ground from the touchscreen circuit to the chassis of the phone, as the proximity of the laptop changes the capacitance of the internal circuit enough to overcome the lack of effect that the chassis alone needs to provide.
hehe I have to investigate to be sure this is a bug relative to my device so that when I will send it in for repair they will have to find a way to solve it and not just pretend it doesn't exist...
try pressing with all skin and not with your nail. It needs heat to work.

No, it doesn't. To prove it, hold a metal spoon and slide it across your screen. Mine works.
this was a common problem on the G1 and the way the capacitive screen was designed. In order for it to be functioning completely, HTC told users that he needed to have it in his hand or at least a finger or two touching the phone. HTC said that it simulated a circuit (the hand on the phone made a complete circuit while just touching it left the circuit incomplete) I have noticed the same thing on the N1... it works great in my hand on if i am touching the sides with a finger and scrolling or using it, but if i just lay it down and try to scroll/touch with 1 finger it becomes much less responsive, the same way the G1 would.
i will see if i can find the exact thread over in the G1 forums where all this is posted.

The only thing I found while googling is that you need some humidity in the air for it to work effectively. I'm really not sure if that applies to this specific design though.
I've never had an issue with using the screen on a table, so this is probably isolated, I'd give htc a call and ask for repairs.
Edit: I just tried for the hell of it doing the pinky touch on the frame, and the soft buttons became much more responsive. Hmm

Nothing is impossible - opening the HTC One. Now with video!

After a trip to a shower my HTC One was declared dead (boot loop even after rice, humidity remover, heat, and others) I figured I would open the phone even it it meant that I could destroy it. It turns out that all you really need is patience and tools already available. Sure, I did bent the upper cover but, hey, everything else is intact.
I started by removing the volume button and started using those "guitar picks" around going down. Added some heat to unset the glue and moving slowly I started prying open the right side (when you are looking at the lcd). Than continued moving down until the left side was stuck. After that I went high on the volume button to set the whole right side open.
Now I'm using the other tool (the one that looks like a lever?) I started opening the left side. This side was a lot harder so I applied heat again. After that the glue wasn't an issue and it started to open nicely. Now I have the phone open and I'll see if I can get it working again.
Sorry for the English. I'm too excited to correct the mistakes and I'm not from an English speaking country.
Edit: added tools pictures.
The guitar picks were used to start opening the phone. The green and blue tool were used to open the left/top/bottom sides. The light blue tool was used mostly as a lever on the right side that was already open.
Edit2:
Video will be here shortly: http://forum.xda-developers.com/showpost.php?p=48832250&postcount=22
Overall experience while opening the HTC One (compared to the iPad 2/iPhone 3G/S/4S/iPod touch 5th/Motorola Atrix/Transformer Prime) I would give it a 4. The iPad being a 2 (almost impossible to open without a heat source and nearly impossible to mount a new glass without issues).

Phone is back. 100% working again. After opening it up I used a hairdryer on the "on/off" switch, left it open to cool down. After an hour I left it charging and left it there. It wasn't boot looping anymore and it turned on.

Same phone. I just glued it back to position with a superglue (superbonder is the trademark I've used). Used a toothpick to smear it gently and used some phone books to keep things in place. The top aluminum part was bent but the superglue is now holding it.
About the video, I'm not sure I'm willing to open it again. It would be awesome tho..

Found no screws. It's stuck together in one piece by some clips on the white border only. It's also glued around the same white border.
Follow-up: The phone is still working fine but not charging anymore. I'll wait to open it again later, in about two days or so, and than I'll video the process to see if there's something wrong. Hopefully it's fixable. And I hope I can open it without issues just like the first time. If it doesn't charge I'll see if I can get a new charging port (maybe the water did some damage by rusting the contacts of the port).
It seems that the phone is playing tricks on me. It's charging today.. Go figure..
Could be the water damage. I read where people with different phones talked about the phone acting weird like it just stop charging or the screen won't come on. That would come and go without warning. Remember my father in law damaged a phone once when he was a truck driver and delivering his load in to a walk in freezer. He made many trips in and out and I guess from the extreme cold to heat made it condensate inside the phone. Where are the water damage labels on the phone beings you had it open?
Sent from my Nexus 7 using Tapatalk 4
Double post.
Water labels are intact and since htc left Brazil we don't have an authorized to fix it so I opened it and saw that there is no water indicator in red. The water damage sticker is below the flash. Look at the pictures and you'll see a white sticker below the flash and another close to the usb port on the lower side of the phone. Not sure if the second one is a water damage indicator..
I'll keep using the phone till I get some alone time to open it. Tho I'm worried that I might break the phone this time (since it's working again - for no apparent reason).
So, yeah, there's an issue with the charging. Not sure if it's the port or the phone. Tested different chargers and it won't charge while it's on nor when it's off. After a day off it charged (yesterday) but now it won't charge. This sux. I have to find out what's going on. So, yes, I'll have to open it again. I can't have a phone that will be used to drive using gps all day behaving it like that. Phones won't last 4 hours on battery alone while using gps.
Added new picture with tools used..
Sorry for the double/triple post, but it's the best way to keep everyone informed..
If I helped you in any way please consider donating something so I can buy a new phone. The HTC One is dead due to an issue with the USB connector or something else that I'm still not aware. I will use this phone as a test bed from now on to see if I can fix other stuff without breaking too so I do need a new phone. You can donate here: http://bit.ly/1a9vqqg
Thanks and enjoy the video! I hope it helps a lot of people.
A video will be uploaded here: (it's 04:37am GMT -2) and still 205 minutes left to upload. Video will be 720p and it's 1.2gb so yeah, it will take a while. But now I'm off to bed. And sorry for my english. I'm ok writing but I'm so so when speaking. I said I would edit the video but since it's just shy of 19 minutes I figured I would leave it like that.
If you guys have any idea on what to do to help me fix the charging issue I would see if I can try that now that the phone can be easily opened. :fingers-crossed:

Check waterproof without putting phone in water - Compare numbers

Hi
As far as im aware, by looking at the pressure sensor, you can see if the phone is waterproof, but I don't know how much it should change.
Mine is going from 1004,7-1005,3. Could anyone download cpu-z and look at the barometer pressure sensor and see how much their number change?
Thanks in advance
Well, no offence but, that doesn't make any sense.
The pressure will vary depending where you live, how higher are you from the coast. So, people just telling their barometer pressure tells you nothing aside of how high above sea level they live.
Secondly, they take into account that waterproof barometers have different sensitivity so they calibrate it accordingly so the readings are precise. You won't see any difference between the reading on your sg7 and a sg6.
Lastly, the only way to know for sure your device is waterproof is do a dive test. Drop it in a glass of water and leave it there for 15 minutes. Tah-dah!
You're supposed to push lightly on the screen and make sure the pressure goes up directly when you press it and slowly go back down. Mine goes up by 0.3 mBars immediately then slowly goes back down even when I continue pressing
It's a good litmus test but of course not guaranteed. I use Sensor Box

Not asking for their numbers, but how much they should change. My Xperia Z3 changed my a few hundred and after broken glass by zero, which proved it was not waterproof anymore. So is asking to see if anyone's is changing by a few hundred by pressing or if the 1-2 mine change is enough.
When it's waterproof the pressure will rise, as air can't escape, so pretty sure it proves.
Hi,
my sensor shows 956,0. When I press front and back it goes to 957,3 and then slowly back (still under press) to 956. When I release my phone it goes to 954,8 and then to 956.
If I try it with SIM tray out, pressure remain same with no change.

Thanks. Was exactlyexactly the answer I was looking for. So if your phone is waterproof, mine should be too. Just wanted to be sure, if most people had as little change in numbers as me, as om my Z3 the pressure raised a lot more.

No special tools are needed and I have posted a video below to show how this is done.
All you will need is a bank card or spudger, a pair of scissors and some cardboard from a cereal box.
You may also need a drop of glue or blue tack.
Although this usually stops all issues on most devices you may still need wakelock but usually it's not needed.

Anyone attempting this please do not go under the glass try push it forward from the battery compartment and then run a card around the edges of the grey plastic. Just go carefully when doing this and don't rush. You can heat the screen with a hairdryer to make removing the phone from the casing easier. It's the best way to do it.
Also you could use Aluminium Thermal pads or Copper instead of cardboard for better thermal cooling. Just make sure its 0.5mm or 1.2mm thick but no thicker!
You will get great 3d mark results using Aluminium, Copper or Thermal pads. "Do not use any kind of thermal pastes!!", You have been warned! But even using just cardboard works great as well.
Don't blame me if you break your phone more by attempting this. But if your phone is not working, you really have nothing to loose.
If you have an old phone you would like to donate please send me a PM.
1. Thanks a lot mate, I can confirm that this method works. At least it helps to turn the phone on/off asap without removing the battery then waiting like before.
2. Also, I am glad to break the front glass, and also cut off the blue wire for phone signal, just by sliding my credit card when trying to open the parts. So now I am ordering the new glass and a set of wifi/phone signal wires.
I am not blaming you, LOL, just to add in some information that anyone who never open the Note 4 themselves would do an extra care on this work.
Well done for your tips!!!
I'm glad it worked for you. Sorry to hear your glass cracked. That's a pain. I do try to explain not to go under the glass when doing this. I'm sorry if it was not so clear.

Couldn't this cause a fire?

No not really but if you like you could use aluminium or copper for better cooling and thermal performance. But it must be no thicker than 3 or 4 folds of cereal cardboard.
This has worked for many people already.
See the comments.

Here I have a 100% fix for the galaxy note 4 emmc error and random reboots,
Including unable to unlock phone, deep sleep issues, and random behaviour.
Also fixes overheating and battery issues as well as makes gearvr work without heating issues.
This is a hardware fix and so far a has been 100% effective on all devices I have repaired,
Its an easy repair and takes about 20 to 30 minutes to complete.
No special tools are needed and I have posted a video below to show how this is done.

Instead of cardboard, I used folded aluminum to the desired thickness and reassembled. My note 4 actually turns on properly where prior the phone would shut off from minor use and had to remove the battery and pop it in the freezer just to turn on.... I did have 2-3 reboots so far but that was after heavy usage (few minutes gaming and gps usage).
I saw a similar youtube video that actually showed a voltage power supply and volt meter to the out put and pressure on the emmc card was the solution as well.
Thanks for the fix! Hope I can get more usage out of the old Note 4.
Yeh I actually upgraded this to aluminium as well. ?
worked
just worked for me....unfortunantly I somehow messed up the home button and the right touch key....guess I went too far in and messed up cable......not sure its worth taking screen off to repair the buttons...using navigation bar app instead.....can still access recovery or download via adb.......

If you find the back button does not work properly its normally down to the screen not being pressed into the housing fully. Try squeeze the the screen into the casing more. It should sit flush.

An update...the home button works when hard pressed and the screen is flush with the case........the "springiness" for lack of a better term is not there...the left optical button still does not work. not sure whats its called, but the button that displays the multiscreen view of open apps is not working...... I typed wrong button in my first post.

You could always install a navigation bar button to get around it.

Thank you for sharing this. I'm going to use a 2mm thermal pad, do you think that will be sufficient?

Yeh sure but maybe do 0.5mm to 1.25mm, I would say 0.5mm minimum but 1.25mm should be ok. Its only purpose is to put pressure on the chip
