Touchscreen / Creaking issues - Info collection thread - Xperia Z2 Tablet Q&A, Help & Troubleshooting

Hi there !
It seems many Z2s have creaking and touchscreen problems, sometimes developing after some days of use.
In addition, a lot of Z2 Tablets seem to suffer of a warped, bent chassis: Just peek along the sides of the Z2, check if it's bent, curved.
My Z2 had NO creaking and NO touchscreen issues right from the start - but both problems came up after about two days of use, both issues showed up at the same time. And my Z2 is a "banana" Z2, it's chassis is bent, putting the device under constant physical tension.
Maybe there's a connection; let's find out !

Please reveal the following:
1) Z2 Tablet model (Wi-Fi/LTE, RAM size, serial number*, date of manufacture - see below)
2) Firmware version
3) Color (maybe different backplanes cause different stress on the chassis)
4) Market (Europe, USA, Asia, etc. - have a look at the box the Z2 came in; there's an information about the country it was made for)
5) Country of manufacture (I guess it's China for all Z2s produced - but you never know...)
6) Days of use
7) Bent ?
8) Touchscreen problems ?
9) Creaking/loose feel at the bezel (especially at the right hand side, in landscape mode) ?
10) Only if you dare: Bubbles emerging from the bezel area (not speakers) if submerging the Z2 ?
* Serial number: You don't need to mention the full number. Just have a look at the sticker on the box, "SN –": Example: 430101690000142
"141" is the serial number.Replace the last two ciphers with an "x". Result: "1XX". If your serial number is "54321", use this: "543XX"
This way, you don't have to reveal your full serial number - but we still get an idea of the production batch number.
Thank you.
Date of manufacture (thanks to LitoNi for pointing me to this):
It's here:

Next Z2 just arrived. Again, a "banana", creaking at the left (!) bezel side right out of the box, slightly larger gaps between aluminum and plastic at the side faces than my first Z2, so build quality appears to be even lower. :/
Serial number is 2410, serial of my first Z2 is 142 (funny, same numbers, just reversed) - so there's more than 2000 Z2 produced between first and second device - but still the same problem. :/
Instant return to Sony.

I know you want to keep this thread clean but when I talked to Sony today they said that I have to send it to service, while it seems like you just get yours replaced? Is that the case and how do you work your magic? ;<

If the problem is still their send it back to sony asking for replacement or money back . Its no magic just stop smoking ,start living well.

Skogstoken ist partly right...
I bought the Z2s in Germany via Sony's online shop.
After fighting with the first problems, I made a major mistake: I called the "Sonymobile hotline" in Düsseldorf.
You can fully skip that step: Incompetent, not willing to listen, telling me there's no exchange of defective devices, just repair. They even told me to ask my dealer, not able to understand the fact they ARE my dealer... Complete waste of time.
Then I used my Sony account for getting information about returning the device - and a phone number in Frankfurt popped up.
I called them, they offered to send a replacement device at no additional costs.
Presently, I am waiting for TNT to pick up the Z2 for return.
So Skogstoken and others: Find the phone number of Sony's repair/return service, talk to them, skip Sonymobile.

i wouldnt call this bent if it already came out of the box like that.. ive had and seen a bunch of xperias z/ z1/ z2/ z ultra/ zl like the picture of the op. These phone are made too thin and theres nothing you can do about it other than blame the machines that made these frames. Basically, this so called "bent" is unavoidable, i wouldnt call this "bent" if its unavoidable, probably 1/100 devices you will find one that is perfectly straight. btw, the frame could be straight when it was made but the plastic coating might have made the frame bent like that.
i went to the store today to see the demo units of the tablet z2 and z2 and both of them are like that. I also decided to purchase the tablet z2 on spot as it just looks too amazing and i needed one for school. Got home and realize the bottom right corner the bezel is loose, its basically pushable...
im exchanging it tomorrow for a new one and see if the same problem still persist, if not i think i will pass this tablet for now... wish me luck :good:

LitoNi: It's not just a cosmetic issue. The bent chassis seems to cause a constant stress on the device, which at some point of time gives way.
My first Z2 (the one I still use while waiting for Sony to send my third device) was stronger bent right after unpacking. NO creaking issues at that time. After about two days, the device got "straighter" - at the same time, the creaking issues started.
So it seems that something inside the Z2 doesn't hold up against the constant stress caused by the bent chassis. This might be the reason for creaking and maybe for some touchscreen-related issues, too.
I don't know that for sure, I am just guessing. That's one of the reasons for collecting some data - to find out if there's any connection between that issues.
Many customers reported having an absolutely straight Z2; so a bent chassis should not be a common, let alone acceptable sight.
If we don't return distorted devices to Sony, nothing will change to the better.
