lookup firmware version on settings->about and try updating the phone
connect it to a pc that has Sony PC companion and the software should recognize the phone as Sony Xperia Z2 (D6503/D6502)
also check the body of the phone see if its intact whether it looks like its been opened before or not
also test the weight of the phone on a weighing scale and check if it is exactly 163 g (5.75 oz) without screen protector i guess
check the internet for photos of Xperia Z2 the color you are buying and check the phone with the photos if they look like the same thats it
it is very unlikely to open z2 replace hardware and reassemble it you cant get away with that it will most definitely leave a mark
+ check the waterproof ability (coz thats important)

There are multiple ways of checking whether it's a genuine phone.
First of all waterproofness. You can check that by testing pressure sensor. Just Google for it and you will know how to do it.
Another thing is that the device model should be d6503/2, but this one may get faked easily.
So test the pictures. Take some picture in manual mode (20mpx) and check the resolution. The resolution should be over 5000x3000 and at least 5MB.
Under right flap there's additional information about the phone, you just have to pull it out.
Anyway, there are so many ways to check whether the phone is genuine.
If you only get an opportunity to hold it in your hand you will notice it.
But for me the waterproofness test (with pressure sensor) would be the main deal breaker. Fake phones aren't waterproof (or don't have pressure sensor).

Is pressure sensor an app?? if it is i have to install that on the z2 and check the pressure i guess..is there a standard pressure limit or amount of pressure that should exist in z2?? (Sorry to bother u..googled it but not so sure what to do)

NO need to install anything.
On the device, goto the phone app and type *#*#7378423#*#*
A new app will open. Go to Service Tests, and look for Pressure Sensor.
Make sure all flaps are closed. Apply pressure to the touch screen of the phone. If the device is air tight, the values on the screen should go up a bit, then fall to the starting values. If you stop applying pressure, the values should change again. If it does this, then it is air tight, and that also means it is water tight.

Whilst in the Service Menu, goto Service Tests, Security.
If the bootloader has never been unlocked, then it should show a bunch of lines of text, each ending with [Key OK][Active].
If the bootloader was relocked by restoring the TA image, then it should show the same thing as above.
If the bootloader was relocked without restoring the TA image, or is still currently unlocked, then it should be different from above.

[Q] Xperia Z2 Water proof

Hello guys, I bought a Xperia Z2 3 months back and never tested it underwater i am actually scared to do it, and also i couldn't find any water damage indicators inside the flaps i can only see the hard reset button near to the sim card slot which is red in color.
Kindly do suggest me can i go for the underwater test...thank you...
They are on the inside of the phone
And for waterproof testing
Close your flaps, open the service menu (google it) and go to presure sensor
The sensor should increase even a tiny bit when putting preasure on the surface of your phone when the flaps are closed
Open your flaps and the preasure sensor should do nothing
This is a good indication of your devicr being water resistant
So the indicators are not visible to us, Thank you for the information.
And i did the pressure sensor test, by closing the flaps with out any pressure the value is 1013 and when i put some pressure the value increases to 1018, 1019 and gets back to the normal value 1013. when i release the pressure its goes down to 1009, 1008 and again gets back to the normal value 1013.
When pressure applied by the flaps open there is no changes (didn't do nothing).
Is my device water resistance...!

It's not sure it was water damage but I think it was, and my phone passed the test so it's not a reliable test. I recommend you to not try with water if you don't want to use your phone in wet conditions, but if you want then go ahead. Also check that your device has build quality issues or not. Look for gaps at the corners of the front and back glass.
why my phone stock or orginal value is too low ?my orginial value is 939 ...

[Q] Waterproof Information

Hello, I had this smartphone for a month, but I read on the internet that, when the Xperia Z2 is submerged under water, the camera becomes blurred.
I want to know if this problem has come on all devices, or only on bad product. I followed the tutorial to find if my device is isolated pressure sensor (the number changes when I press my device).
So someone used Z2 underwater? How did you find problems after use?
Z2 camera shouldn't blurred if submerged in water it's either
1- you didn't properly closed sdcard or charging doors and water gone inside
2- your device has build quality issues
Th3 fact that you checked the pressure sensor and you found it working as intended is that it's th3 first reason which is your fault
I used my z2 multiple times under water and never blurred my camera or anything
I submerged my Z2 in water, took some photo's with flash and without it and they were perfectly clear
No blurred photos. So I guess if your test was succesfull, your Z2 is waterproof (Mine was for repair and still after that my waterproof is working perfectly well ;D) and you can use it underwater and take photos
Thanks for the reply, i also bought the magnetic dock station to not stress the fisical closure. Ok i tested it under water...... it's all right
Hi, this is how it has become the camera and the flash led after a few minutes of use in water, not water but only moisture, believe is normal considering that the water in which the smartphone was warm enough? Or do you believe there is an infiltration of water?
Well I am sorry to say it seems like your phone is defective. That is not normal
So i will contact the assistance to change it....
My smartphone is made in stock : 14W51
So did you do the pressure sensor test before submerging it into water? Did the pressure rise?
I hope they exchange your phone, please keep us updated
I tested my Z2 before submerge it under water. When i pull my smartphone the pressure sensor display a number higher than i don't pull Z2 , but the number return the same of before , after any second of pression.

Frame broken after drop. Need advice.

Hi all.
I dropped my z2 and now the middle frame is broken and kind of seperated from display. The width seems to get bigger with time. I'm afraid it could damage the screen.
What could you advice me?
Should I try to replace the middle frame only?
I have had a nexus 4 before and have successfully replaced the digitizer by seperating it from lcd without damaging lcd.
Oh. Damn.
Of course I would check for some tutorial on the Internet how to disassemble the phone. If it is like doable-level then I would go for it. But if it would seem to hard, like if you could damage something easily then I would leave it the way it is.

Luckily not from an iPhone = Yesterdays technology at tomorrows prices
Ok I managed to change the frame but now my phone's sensors stopped working (accelerometer,proximity)
In service menu the proximity shows off always, and the accelerometer test also fails..
Any advice?

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.

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.

Mate 10 Pro waterproof test without water?

Back in the days when I owned my Xperia Z3 there was a thread (linked below) that helped users check if their phone was waterproof by using the built in pressure sensor in the hidden menu, if you want to read it in detail then I've linked the thread, but basically once you where in the pressure sensor test you'd slightly compress the phone using your thumb and index finger by pressing on the display and back.
Then: (From OP)
"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"
So basically my question is, is there any equivalent of this for our Mate 10 Pro, I had a nasty drop recently and I'm concerned it could have potentially compromised a seal or something, and water damage isn't covered in our warranty so I don't want to risk it.
Please no replies about how I just shouldn't use it underwater etc. I often take underwater shots with my Mate 10 Pro.
Any help/replies are really appreciated

Simply download sensors app from playstore, open pressure section and check if the pressure rises when you apply force to the device...

A lot of the sensor apps don't actually measure the pressure of the phone they do the air pressure based on your GPS location, it's hard to differentiate the 2 when searching, also I've read that third party apps don't give a accurate reading without root access, that's why I specifically referenced the Xperia thread because that one was accessible through the built in hidden menu from Sony themselves.

You literally type sensors in the playstore and download the first app - sensors multitool.
Root access isn't required to perform such check. Even the thread you linked clearly states that the function found in the factory test mode is basically a barometer output readout which means any 3rd party app that is able to read sensors data should be fine.
Tho your device might still seem water resistant upon performing this, keep in kind that it only tells you that the seal isn't broken yet.
Meaning even a small splash could reach into the device if the seal is already weakened .
If you have any friends that are in the repair business ( Repairing latest flagships ) ask around, they usually have tools for determinating water resistance of devices after repair.

Thank you fo the tip. Could someone kindly post a screenshot of what fingers' pressure produce on a graph ? I had my Mate 10 Pro opened at a Huawei Repair center for a screen replacement (OLED oled burn in), and the pressure graph does not show any relevant variation...
Before and after they proceeded with screen (and back cover as they messed up the first time, it was not perfectly glued) replacement, I asked them about IP waterproof/certification, they answered me they take care of this applying a new seal...

It's worth me mentioning that I still haven't submerged mine in water, the slight spikes in the graph show when I applied pressure.

Yes, but not by much.
From 1003.5 to 1004.0, this was using a lot of pressure.
If I use "normal" it only goes up by 0.2

If yours is 1003 and mines 1015 and you know that yours is waterproof then I can only assume mine isn't right?, If you get a moment could you take out the SIM card tray and see what the number changes to? Because with the SIM tray out, then the phone obviously isn't water tight.

When removing sim pressure does nothing. It stays at 1003
But I guess, if yours was broken it wouldnt react to pressure either.

I have never done that. But I haven't dropped it either... So I can't say for sure it is waterproof.
But I can compare to my Mate 9 which has been dropped a few times, not by high heights but anyway.
Edit: Removing case from mate 10 pro increased pressure rating to 1004. But it's exactly the same on my Mate 9. I guess altitude counts in too?

I'm not too knowledgeable on the whole subject which makes things worse, hence the thread lol, I don't know why yours is 1003 and mine is 1015, if my phone wasn't water tight wouldn't the number be lower that yours which is water tight?

I guess it would need to count in air pressure too...
I'm trying to find SOMETHING on this subject, but most topics are about already broken seals...
But as you wrote in OP, the seal should be intact if pressure goes up when you put pressure on the display. Which it does for both of us.
Right now it's 1009 hPa here in the air, 42m above sea level. I will check again tomorrow and see if 1004 increases or not
Edit: And checking the posts in the thread you linked in OP, all of them have varying "start" hPa.
Edit 2: at 1004,7 now

Where I am it's 1019 hPa and 30m above sea level.
The information around this subject seems to be scarce, hopefully someone who knows a bit more will check out the thread and have a different insight.
Mine is 987,7 hPa (altitude 215m)
When i press, it goes 988, 2 hPa
