Hello i've got the c6833 une week ago, i am experiencing a weird issue.

It happens very randomly, when i just use the device, often when i am typing, suddednly get crazy and start to click itself on several letters. Just when i keep the hands away the device, it stops and everything could back to normality, except one time, where it just kept touching icons everywhere by itself, so i had to turn off and then on again the device.

I do not use the device while keeping it plugged to charger, as long as i read around that is an issue sometimes caused by this.

Also i use the device as a tablet without any sim card inside, and i am on firmware 14.1.B.1.532

Anyone can help me?

Thanks

yes..i've read around, several users facing the problem.

There is way to going back to firmware .510 ?

I think i started to have this after updating to .532, but i am not sure.. i would like to get back to old firmware, before sending the phone for service..

You will have to use a thirdparty program to do so, flashtool, or you can just take it to a Sony repair center

How has Sony not responded to this yet? I'm fighting the phantom screen touches on my Xperia Z Ultra, this is a joke Sony.

Clear screen guard attracts screen prints from the flip cover (default leather cover) and if not cleaned regularly (wiping off) it'll result in this random clicks issue. Try using a Matte screen guard instead and this problem would resolve to a gr8 extent. I've tried it and am quite satisfied.

Same here. Get a matte screen guard or get used to wipe your screen clean before you use ur marvelous device. It's tempered glass, why put a protector on it? :))
