Touch Problem...!!!

[diplubond]

Previously I was using 4.0.4, On last week of February 2013 after turning on Bluetooth, my phone was in continuous boot mode...!!!

Sony Service Center solving this by downgraded to 2.3.4

But now there is an another problem, which I don't suffer in previous...!!!

Touch is not working properly...!!!

Sometime it's not responding...!!!

Is there any solution for me...???

Can I update my phone to 4.0.4 ???

If I flash my phone using Sony flashtool, Is then warranty void ... ???

Regarding the touch screen i recommend that you contact the service center again. It should work fine in both 2.3 and 4.0.4.

Flashing the phone using 3:rd party softwares may void the warranty depending on the problem but you can of course flash the phone using PC Companion or Update Service without voiding the warranty.
