My Xperia Z failed the water test out of the box!

Hello all, just wanted to inform all that I've experienced this odd thing with the Z that no one has seemed to have gone through, not sure of course...
But before anything else, as it was a huge selling point for a lot of hiking and travelling me, the water proofing needed to be tested.
I took it out of the box, peeled the plastic protectors off the front and back glasses, threw it in a glass.
- Now my camera has some fog inside, the volume down button has started to work again after half an hour, the loudspeaker is understandably very bad right now.
- Currently trying to get the fog out of the camera and hoping the loudspeaker to go back to normal.
- I will contact Sony tomorrow to discuss the problem and will update this as often as I can.
/**************************************************************/
Solved!
- As Akiainavas has pointed out to me, it is actually written in the instructions manual, it is normal for the camera to get foggy between shifts from under water to outside the water, I've tested it work perfectly under water.
- Once dried out, all is good, it just took a lot longer for me compared to other people because of the low room temp I am used to I guess.
- The phone is all good, all working.
* Now on the to-do list: Unlock, Root, Flash, Enable Bravia through the whole user experience!

I heard that this is actually not uncommon. Let it dry. Try again tomorrow.

Indeed, i tested it the day i got and noticed the sound was very low after it was wet. After a half an hour (max 1 hr) sound will come back with normal volume. It's some protection thing i guess

It's just water on the speaker membrane that distorts the sound. Haven't got my phone yet, but try blowing it out. Waiting it out should work as mentioned.

Still have that problem?

Maybe its a faulty device with regard to that camera fog.... Can happen to one in thousand devices...
Surely sony will replace it...

This brings up a Good question. Has anybody read the warranty?Does it actually Say You are Covered it you purposefully dunk it in a bowl of water?
I mean I understand there have been demonstrations doing this but it Seems like a really silly thing to do with your brand new phone

the matter is...
xony xperia Z has the CERTIFICATION, wich isn't something you say you have, is something that has to been tested by a specific organization...
so if is certified i think you have warranty right...

never had any issues with fog in the camera on my xperia acro s, even after having it in my pocket while swimming
the speakers issue is common though, but thats expected, as water is going to get inside the speaker holes no matter what, but all I need to do is just shake the phone and blow where the speakers are and they work perfectly fine after that

Uh...did you even at least try to test out to make sure the phone is working good before dumping it into the water?

Right, it's been 12 hours now, I left it to dry out in a bag full of humid absorbing silicon bags over night.
- Right now the fog inside the camera lens is gone.
- However I think it is out of battery so I plugged into charging.

Exactly what I have in mind, I will be contacting Sony about this no matter what, the phone failed the water test out of the box, it is a feature they promote and demonstrate heavily. If they don't cover it in their warranty despite all the promotion and the effort they have put in this phone, then they are just idiots who have absolutely no idea of how one device failing like this can damage the image if they don't back it up with their warranty.

Yes, it was all fully working - tested its other features without opening any of the covers to make sure the water test was legit for an hour or so.
/***************************************************/
Update: The phone is working, buttons all working, speaker working, camera fog gone and this time it didn't come back as soon as I took it out of the air lock bag.
I am still contacting Sony to get information on what I should do, how I should feel...
I will test it again after my talk with them and on the direction they've given. Mind you, I tested it only in a half full glass of water so what I will do is to try and reproduce the problem.
/***************************************************/
Update 2: I have just noticed that the charger is actually 1.5A and you cannot charge the phone from a computer unless you have a non-standard USB port like a 3A one that Gigabyte motherboards have.

Put mine in a vase of water yesterday for 5 mins and all was well, love it

When submerged, and after that:
- Speaker will have very low volume for a while, until it dries off
- There might be a "fog" on the camera because of humidity and temperature differences
- Hardware buttons might not react perfectly until the water dries off
It's perfectly normal. It's in instruction manual... but whoever reads those these days

Quick copy and paste from the Sony UK website.
"[2] In compliance with IP5/7 and IP5X, Xperia Z is protected against the ingress of dust and is water resistant. Provided that all ports and covers are firmly closed, the phone is (i) protected against low pressure jets of water from all practicable directions in compliance with IP 55; and/or (ii) can be kept under 1 metre of freshwater for up to 30 minutes in compliance with IP 57. The phone is not designed to float or work submerged underwater outside the IP55 or IP57 classification range and should not be exposed to any liquid chemicals. If liquid detection is triggered on the handset or battery, your warranty will be void."
So it's only designed to be water resistant, and if it gets water damage, you're out of luck.

The thing is - it won't get damaged unless you leave the covers open. I asked Sony about it and apparently they have some tests to determine that - most likely a water detection that can be used even when the phone is dead. I think they'll probably just close the covers and put it in water to test it again, if waters gets in - it means your covers are flawed and you'll get a replacement. If not - it means you fkd up and you won't get your phone replaced.

If that's the case then then that's awesome!
It'd make sense too, as what's the point of going to all the trouble of getting it certified water-resistant and advertising it as one of the main features, and then saying to everyone that gets the slightest bit of water ingress that they're f**ked.

I trust Sony in this aspect. There are water sensitive tapes under every cover ( those little white things ) so they'll know which one leaked.
Also, remember what happened with Tablet S - it was supposed to be waterproof, but they detected a manufacturing defect that caused some of them to leak. Sony called every customer to Sony Center and provided a replacement of their device - dead or not, warranty or not... that's how you do it.

I've read it somewhere that the interior also has water resilient coating actually for when tiny amounts of water goes in, I wonder if that's why the camera gets fogged inside because I just don't get how there can be fog when there is no humidity allowed into the interior components as long as you are in the limits of the IP57 certification.
Am I wrong in this? Does water proofing not mean the device not allowing any humidity inside whatsoever? or Is it that the air molecules carrying the humidity inside can still get past the water proofing?

I'm much more likely to spill beer over it rather than water in perfect honesty, so thanks for the info there!

[Q] Improving waterproofness

So I got my new Z3C and was thinking: what if we can make flaps and audio port more waterproof?
Doing pressure sensor test I get reading around 1000 and it's increasing by about 30-40 when I press against screen with closed flaps. But it normalizes after 1-2 seconds and goes back to initial reading meaning tiny amount of air escapes. Does it mean my phone is not totally waterproof? Don't know.
Since this phone is just fresh-water proof (meaning no using in pool or sea) and I really want to use it worry-free in all kind of water that I dare to go in myself I really want to improve waterproofness.
I'm not worried about front and back since glass should be all.kind-of-things-proof. This leaves sd card and sim card covers, audio jack, mic holes and speakers.
So what I thought of was to "grease" flaps' rubber o-rings with rubber compatible oil/grease to make better contact with phone body or use some kind of silicone spread around rubber contact area before closing flaps to have semi-permanent seal and be still able to open and scrub extra stuff off without doing much damage.
For audio jack I thought to make some kind of plug - like pressy button but with a bit bigger "head" that has soft sticky rubber underneath so when pressed in it makes a seal with the edge of audio jack or even plug that is covered with silicone all the way.
Speakers and mic holes could be protected with bits of strong adhesive tape - it's easy to get sticky stuff off the glass and it'll be possible to hear some sound even with speakers covered. Not sure about mic holes because side plastic has matte finish but some strong adhesive should still stick?
So the question - has anyone tried something remotely related? Is it thinkable? Have I missed anything important? What materials (grease, silicone) should I use?

If anyone has done something similar? Probably... But no one ever posted about it on this forum. You can use the phone in the sea and swimming pool, as long as you rinse the phone afterwards. As for modifying the phone, I wouldn't do it. It might cause you to lose your warranty.
In terms of waterproofing the phone even more, I'd look at waterproof cases made for other phones with almost similar dimensions and see if you can do something about the case instead.

Plenty of stories of people going in the water, damaging their phone and fighting with sony about warranty.
It's hardly modifying, adhesive sticker on glass is easily removed and thin film of silicone should be also easily removable.

That's the option. But I haven't seen any slim waterproof case that could be comfortably used all the time.
Anyway, curiosity is strong and I'll most likely try different options.
PS. can someone test pressure sensor - is reading staying high when screen is pressed or it fades back to normal with all covers closed?

I've just used mine in pool all weekends since I bought it without any issue and even without afraid of doing that! The same with my wife's Z1!
And I'm contantly opening/closing its usb port due my xposed modules development (debugging purposes)! Maybe some unlucky day I will screw it... who knows!
Ofc we always need to be sure all ports are properly closed before going to have fun!

Sorry, I forgot about the pressure sensor part, it's normal that the numbers go back to normal after you lifted your finger, it works like that for everyone.
If my mind serves me right, I've seen Sony ads with the Z3C being thrown in a pool or something similar, so a pool really shouldn't be a problem. And yes of course people will have to fight for their cause at Sony, they won't just put any phone under warranty, else people would exploit that.

I probably expressed myself bit vaguely. Thing is that pressure reading on my phone returns back to normal WHILE HOLDING screen under pressure. Initially pressing screen creates greater pressure inside the phone, reading rises but air escapes quite quickly (1-2seconds) and pressure reading normalises. After releasing finger screen pressure sensor shows lower readings for a second until extra air seeps inside to equalise pressure again.
Hope it's clear enough.
Also, does it mean that I got less waterproof phone that it should be?

I dunno about you but i've been using my camera in the pool for a while now and even for hours at times

I've used mine under water as well. OP if you're really worried about it you can send it off to liquipel and have them make the phone even more waterproof

How much do you know about the waterproof function of mobile phones?

Some people have misunderstandings about the waterproof function of mobile phones. They think that if the phone has a waterproof function, water will not enter the phone. This is not the case.
Waterproof rating is 0-8.
IPX-1：Protection against vertically dripping water
IPX-2：Protection against vertically dripping water when device is tilted at an angle up to 15 degrees
IPX-3：Protection against direct sprays of water when device is tilted at an angle up to 60 degrees
IPX-4：Protection from sprays and splashing of water in all directions.
IPX-5：Protection from low-pressure water projected from a nozzle with a 6.3mm diameter opening in any direction
IPX-6：Protection from water projected in powerful jets from a nozzle with a 12.5mm diameter opening in any direction
IPX-7：Protected from immersion in water with a depth of up to 1 meter (or 3.3 feet) for up to 30 minutes
IPX-8：Protected from immersion in water with a depth of more than 1 meter (manufacturer must specify exact depth)
The phone supports waterproof but not professional waterproof, it is splash-proof and water-resistant. The mobile phone has reached the standard waterproof level at the factory, but it is not permanent. The bumping, squeezing, falling, etc. in daily life may damage the waterproof membrane and reduce the waterproof ability.
Therefore, it is recommended to avoid contact with the water source during normal use. If your mobile phone does not support waterproof function, you need to pay more attention.

I have never water damaged a phone which is ip68 and I use them in water a lot. These are just bad manufacturers excuses. As long as you wash the phone off with fresh water and allow to dry properly before charging (and don't buy Sony phones), you're good to go.

Calling it waterproof all the time won't help your point here mate ? it's *water resistant you'll want to put instead.

Blury camera, please help (hardware issue)

Hi techies,
My pixel 4XL has recently had a water accident, everything works perfectly now except the rear camera is cloudy and cant focus properly. I opened the phone and wiped the lens with a good amount of robbing alcohol, its even worse now. So what should i do? Do i have to open the entire camera module and wash the tiny lenses and the sensor or what? I really wanna repair it myself instead of buying a new sensor because it takes so long for me to arrive.
Thank you,

Pixel 4 XL is IP68 water resistant (up to 1.5m for 30 mins).
Has it been opened before?
If you used isopropyl alcohol, then there should be no problem, but it should be dried for a long time after such an operation.

Well, I am not an expert on cameras but the cause of your blurry photos may be caused by:
-The motor of the camera don't work, so the lens can't move and as a consequence don't focus
-there is water inside the lens or in the sensor (which can't be seen unless the camera is disassembled.
If you have water inside, as it manage to get in it may be a way for get it out. I would suggest you to take the camera module and heat it up with a hairdryer so water can evaporate and get out. But don't heat it up too much do, it could damage the sensor.
However as you said you used alcohol, it leaves some residues which if is the case, with this method it won't be fixed.
If this doesn't help you would then I think you would need to disassemble the camera. Iwill leave a link to a video off a guy who disassemble an Iphone camera. It isn't the same, but it's similar Here
Also are you sure there isn't any software related causes?
Good luck

Thank you for the reply,
I'm sure the problem is the water+dirt or residue inside. Ik the water has been gone since then and alcohol is evaporated but there must be some dirt sitting in there. This phone has never had a force to get some component cracked inside.
As for the software thing, i'd say i dont think so, what software related issue it might be? Since the front facing cam works just fine, the cache has been deleted, i even downloaded open camera to take more control over the sensor manually. Its just foggy. Like some filter has been applied to it.

Idk if it was, since i bought it in mint condition second handed. The alcohol i used was 96% Ethanol, not the same as the isopropyl, but i dont think of a major difference, but probably some dust has gone there underneath the lens.

Do not use ethanol for electronics, because you can dissolve many components. Besides, ethanol contains water, which harms electronics. That's why isopropyl alcohol is used, because it has much lower dissolving properties, and if it is pure (99.99%) it absorbs water and causes it to evaporate faster from the cleaned items.
Show the picture you take with your camera.

I have marked the centric area that diffuses the light. It could be a dried-up blob of whatever you washed the lens with. The liquid could easily penetrate the camera and get under the lens or even onto the matrix if the seals were not tight.

Yes most probably that's the case. So wha's your suggestion for me? Tear the lens down, wash the components inside it with soap and water, dry it out and reassemble? Or what to do? Im kinda disappointed now. Been shaking and tapping the lens since yesterday with no success lol.

If you still want to use this model, I advise you to replace the camera with a new one, or recovered, so that they are original.
I do not ignore your self-denial and other talents, but I think that you will not fix the camera yourself.

Ok then i have to order a camera lens then, are those sub 10 buck lenses from Aliexpress oem parts? The reviews are excellent but the prices are syspicious. Plus, i almost forgot to mention something. There werw two sponge/rubber curcles (whatever the material) arround the camera lenses, which locate between the cameras and the outer glass. (i marked them) when cleaning, they chopped off. Any chances this be a reason the light doesnt diffuse the right way?

It is for this purpose that the cover glasses are blackened or coated with other coatings so that there is no side light. Gaskets also serve this purpose. The tube of cameras and scopes has been made of blackened material since the oldest times.

Proximity sensor always shows high (far) value after screen replacement

My Galaxy M21 phone's AMOLED screen got damaged due to liquid penetrating a few days ago. I went to the repair shop and asked to replace the screen with LCD one.
After replacement, everything is working fine, except for the proximity sensor. It always reports far proximity even if I bring a surface completely covering the screen. During calls, the screen does not automatically turn off when bringing it to my ear.
I have asked the repair person, and he replied that the LCD screen does not have holes to accommodate the sensor properly, so it is blocking the sensor. But AFAIK if that's the case, the sensor should always report near value, not far.
Is there any solution for this or is this a known problem due to LCD screen replacement?

Welcome to XDA
Not really if the mobo doesn't support the alien hardware.
The firmware instruction set may able to be altered to get the new hardware to work as you want.
It been better to use the original display, but not doing so you opened a can of worms.
Water damage? Possibility of mobo damage as well particularly if the battery wasn't quickly disconnected. If it was salt or brine water it's already dead.

By water damage, I meant a small amount of water somehow got into the screen and darkened the screen slowly starting from one side (a common thing on AMOLED displays).
I can assure that the water didn't cause any problem other than the screen, because I regularly check the device stats & sensors. The proximity sensor is behaving like this after screen replacement.

Well the former of what I said then applies.
I'm surprised it will even function with an LCD.

Sorry to barge in friend,
Thats why I am very careful with 3rd party repair vendors, I have lost many phones to them, they REPLACE new hardware with old spare components,its a bad habit they have & thats why the OEMs have "Authorized Service Centers" exactly for this reason.
For Shamshung devices I suggest you go to Shamshung Authorized Service Center only as Shamshung parts are quite in demand because of good build quality.
Small Story: Few days ago I went to Shamsung Service Center to try to downgrade my M21 from A13 to A11 (my phone is within warranty) & as expected they told me "only upgradable not downgradable sir!". I knew they were lying because a friendly shamshung service center guy once told me they do everything there internally, they have repair softwares there. Anyway, so I took the phone to a 3rd party repair station and the owner named Salman told me he has downgraded so many Shamshung phones of newer models, all I have to do is leave the phone with him for about 10 hours & he will downgrade from A13 to A12.5 then to A12 then to A11.5 and finally to A11 so it will take time, NO! he was lying! He was charging me a biggish amount but not just that he needed 10 hours to fix the mess that would happen when he stole & replaced the new components with older ones. Thats why Authorized Service Centers only friend.

@OldNoobOne I already went to Samsung's authorized service centre, but they only can replace the screen with AMOLED.
I was desperately trying to avoid AMOLED screens this time because they get damaged easily and are more fragile than LCDs (that's my experience with them).
Don't know how much correct I am, but I have seen most AMOLED screens getting damaged completely due to the slightest of shock or due to a single drop of water somehow seeping into it. I have never seen this type of problem with LCD screens.
Looks like I should have bought a phone with an LCD screen in the first place.

Don't know how much correct I am, but I have seen most AMOLED screens getting damaged completely due to the slightest of shock or due to a single drop of water somehow seeping into it. I have never seen this type of problem with LCD screens.
Looks like I should have bought a phone with an LCD screen in the first place.

Yes friend, not just that LCD screen phones tend to consume lesser battery too. Another way to avoid AMOLED issue is that is to use a plastic pouch during rains etc. (there is no problem in communications) or also use a flip-cover instead of normal plastic/rubber back covers only. Just use a good quality scratch/screen guard like 3D+ and LCD will look quite like AMOLED

That makes perfect sense. Using an aftermarket LCD display does not.

All phones should be kept dry regardless of the IP rating. As you found out the AMOLED diodes used in displays are water soluble. The displays are sealed but if the seal is breached by water they will be destroyed in short order. Always use a good case to protect from impacts and high G loading induced damage when dropped. Wipe all water off immediately.
This N10+ in my has always been in a good case and unfortunately has been dropped onto concrete many times (zero visible damage). It has well over 8k hours on it. The display shows no sign of damage or degradation whatsoever. Don't use in direct sunlight and use manual brightness keeping the brightness at 50% preferably less it will get many years of service.

AMOLED displays use -less- battery, have infinite contrast (pure black) and the best color gamut. Higher and variable refresh rates are also possible, but these tend to use more power.
They are more expensive and have shorter, finite lifespans. Other than lifespan they are superior to backlight LCDs. That's assuming you protect the phone from drops and the design/QC was good when manufactured. Of course display quality can vary from manufacturer, model and individual displays. It could be you got a defective AMOLED display from the get go. Samsung's QC has been slipping in recent years it seems. A used N10+ in good condition might have been a better choice than a new midrange Samsung. It remains one of the best phones Samsung ever produced.
LCD displays are easier and cheaper to manufacture so you pay more for AMOLEDs.
If you prefer LCD displays by all means use them.
They are more rugged but not bulletproof by any means.
(Always protect LCDs from solvent exposure like isopropyl alcohol; they are open vented to the atmosphere and solvents can poison/destroy them.)
