I also started to have many dead pixels on the black background after 1 month of usage. It looks like a scattered dots of diffrent colours all over the screen. I took the tablet to the service and they issued me a paper that my device was bended and my guarantee was forfeit. I never bended it and never dropped and there is absolutely no visible damage on the screen or the body.
Then I complained to russian branch of Xperia care. They made an "investigation" (requested the same information from the same service ) and also issued a refusal. What kind of investigation is it??? they should at least make another check of the device in a diffrent place.
I never expected this from SONY.

I encounter the same problem. I bought my Z2 tablet 16GB from the Singapore Sony Store. I got it for one month and the same pixel problem appeared.
I send it in for servicing at the Singapore Sony care centre at 313 somerset outlet.. One week went by and nothing happened. The service was bad, no reply from the customer care or technician. They gave me a website so i can check the status of the servicing but all it shown on the page was pending.. one full week and still pending. I had to call them once and asked them what happened, the Sony personal over the line could only say they can check and get back to me. The next day i called again to check if any technician has even start and immediately right after that they called me to go down to collect. Turn out they are giving me a new tablet. And the screen protector was not refund to me as they said that the device was still in the service centre.. had to buy a new one for myself.
Such a disappointment in the servicing.. and now the current one i am holding as the same freaking problem.. also i notice the corners of the screen has some yellowish hue.

Same issue here for the Wifi version bought in the UK.
Am about to send it in for assessment, but very concerned reading the issues here. Defintiely not a one-off issue.
And it's right in the centre of the screen. Had it been dotted (no pun intended) around the edges, that would be different but it's in the full field of view.
Does the same thing happen on the phones? I was considering getting an unlocked Z3, but I'm wary now, and much will depend on how this is handled.

I had the same issues.
Brought back the tablet to the seller, he specified in the issues description "spot on the screen" well... That's a verry acurrate description. I hope repair center will try a black screen on they screen diagnostics.

My Z2 tablet has this effect on it now. Got the extended warranty.
If they're fixing this issue under warranty, I'll get the ball rolling, but if they're (Sony) denying it's a fault, then ... what?
Anyone get a z2 tablet with this issue fixed on warranty in the uk?

Have same problem with these dots on display. Service centre changed 4 times display and after some time (couple weeks or after month) those dots appear again. Now I'm trying to get my money back. Display in Z2 tablet **bleep**.

i too now have the same problem after only a few months of use. Can only be seen whilst watching a video during dark pictures what can i do?
Was there a firmware upgrade that has made this happen recently???

So is this a firmware issue do we think?
Reports of multiple screens being replaced, but the issue persisting would suggest so,
I can't remember seeing these speckles before 4.4.4, I might enquire over on xda.
Wondering if maybe someone had speckles, then perhaps installed a community ROM like CM, perhaps the speckles went away?
