Xperia Z1 C6906

Whatsup?
Do any of you guys know if the Xperia Z1 C6906 also have the Touchscreen problems?
Because I just received my Xperia Z1 C6903 last Wednesday and now I can't use the phone at all, it just select random apps, making phone call on it's own, scrolling on it's own etc etc., when I first got the problem I did a factory reset, it worked good for just a few minutes, but now I can't even access the settings page, imagine to do a factory reset, I like this phone a lot and I wanted a good working phone and was wondering if I buy the C6906 would be a safe move or all of them have the same problems?
Or should I wait for the Xperia Z2? but don't know how much I have to wait, when will it comes out?
Or is there a fix for this problem?
Anyways thanks a lot,
Aruman
You're not dealing with a flaw in the C6903, you just have a bad handset. Return it or take it to a Sony Service Center. All of the C690x phones are identical except for the radio.

[Q] Suddenly screen went black

I bought my Xperia Z a year ago and the phone worked perfectly all the time but everything changed yesterday.
Yesterday when I was playing Modern Combat 5 on my Xperia Z, the screen suddenly went black and I thought it was just a reboot.
However it wasn't going to reboot - the phone powered off! I have to switch it on manually and nightmares were approaching.
Then, the condition became more and more serious and the phone often automatically powered off.
I thought it was rom related so I re-flashed stock rom via Flashtool and wiped everything this morning.
Now it's even not able to boot - powers off when displaying boot animation.
If the phone is connected to a charger, it won't power off and works like before.
Why and how can this problem be solved?
Thanks!
If reflashing hadn't worked, then most probably it's a hardware related issue. In most countries warranty is 24 months for a product. It's been less than 24 months since Xperia z launched so i guess you still have warranty. The best thing you could do is to send the phone for repairs.

In China warranty is only 12 months so I have decided to repair my XZ by myself.
After times of testing and consulting, it's believed that there's something wrong with the battery.
I have bought another battery and some tools, I will peel off the back panel of XZ and replace the battery.
Thank you!
