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:


This is how it looks like if your Z2 is bent:

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.

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? ;<

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.
