Screen input without touching

[jazz1237]

On a brand new Xperia V, when opening up an application, it randomly goes back to the home screen, and it continues clicking as if the touchscreen was still sending signals. Then, if I try to touch it, it does not respond. I have uploaded a video so you can see what I mean: http://www.youtube.com/watch?v=LFPQlECzOBo -totally random stuff and unuseable. 

This is a brand-new, just unwrapped phone with no extra applications installed. Tried repairing using sony bridge but it did not work. Do I have any other option apart from returning it?

I have the same problem. Any tips? Can I fix it by myself?

It seems software issue.You tried to repair and it did not change anything or you could not repair?

[jazz1237]

Hi, Yes I tried repairing it but nothing changed.

Contact a sony service,pay them a visit.

[NazerschoN]

Yeah, so only Sony Store can fix it? :C Jazz tell us what thay do if u go earlier to them than me

Of course only a service can fix it THE RIGHT WAY.You can also change a digitizer,but after a tutorial,which may go wrong.

So the phone is still covered by warranty,right?Take them the phone,you have no cost anyway.See what they say.

Yeah, but should i go to Sony Store or to the place where i have bought it? (Whatever it's brand-ner phone)
